Now more than ever, return on investment (ROI) is vital to businesses of all sizes. Firstly, you must accurately calculate the ROI you will achieve from a project to gain approval. Then, ROI needs to be measured to demonstrate you have met or exceeded your goals.

ROI within a business case must be aligned with monetary values as much as possible. To gain approval for a learning program, the business wants to know what financial gains there will be.

Challenges of measuring ROI

For learning and development teams, predicting and measuring ROI is difficult. Understandably, ROI is aligned with financial gain for the business. And although the benefits of learning and development are clear, aligning them to a monetary value is complicated. Moreover, a learning program can contribute to the business indirectly or the true benefits can accrue over the long term. These factors mean that getting significant investment for new learning and development programs is complex.

How to measure ROI

As we have established, businesses want to see a monetary ROI value to justify learning and development spend. Once implemented, continued ROI measurement and reporting are vital for continued investment.

The challenge is every learning program is different, so it is difficult to use an ROI tool that fits all scenarios.

That said, there is certainly room in your ROI calculations for the best-known tool in the industry, the Phillips ROI Model.

Phillips developed his methodology in the 2000s, which builds on the original Kirkpatrick Model, which was developed in the 1950s, to include ROI. It compares the program’s total cost to its total monetary benefits, calculated as a cost/benefit ratio.

To achieve this, you need to isolate the training benefits and eliminate any non-training factors that may have contributed to the business impact. For example, competitive environment and seasonal effects that temporarily contribute to business improvements.

Calculating Return on Investment

Phillips ROI calculation is:

ROI = (Total Program Benefits – Total Program Costs ROI/Total Program Costs) x 100%

For example, let us assume that we are going to measure the effectiveness of a training program on health and safety for 50 people. We know that because of the program, the number of accidents has been reduced by 20 throughout the year. This has directly increased the company’s revenue by £100,000 per year. The total cost of the program was £50,000.

So, the benefit-cost ratio (BCR) is: £100,000/£50,000 = 2. In other words, for each £1 spent on the training program, £2 is returned.

Using the Phillips ROI calculation, the ROI of the program is calculated as so:

(£100,000 – £50,000/£90,000) x 100% = 55%

This means that every £1 spent on the program is returned and an additional £0.55 is returned as a profit.

Read the in-depth guide to Phillips ROI Model

Assigning Monetary Values to Tangible Learning Outcomes

It is easy to do an ROI calculation with sample numbers for an abstract example but in practice, it is a complex exercise to put monetary values on learning outcomes. Unfortunately, to build a successful business case and a successful learning program it is crucial you get an accurate ROI. That means selecting metrics that will accurately show the benefits of your program.

Hard data that can be converted easier include:

• Additional sales: Profit from these sales
• Employee time savings: Cost of the saved time calculated based on the average rate per hour
• Reduction of equipment downtime: Can be calculated in comparison with the results of the past periods
• Reduction of employee turnover: Money that you save on recruitment and onboarding
• Quality improvement: Money that was saved thanks to reducing the number of defective items
• Reduced costs: Online courses eliminate travel expenses and the time it takes to travel to and from the learning venue.

Identifying and Reporting on the Intangible Benefits

Whilst every effort should be made to assign a monetary value to as many learning outcomes as possible, sometimes it cannot be done. Most learning programs will have intangible benefits that fall into this category. For example, finding metrics to demonstrate how your learning program has improved the public image of your organisation or how it enhanced the company culture is difficult.

The challenge is this soft data is subjective so even with the best intentions, the data is often inaccurate and not credible.

If in any doubt, the ROI Institute offers some guidance:

The Impact of Digital Learning

The rise of digital learning, or e-learning, as part of a fully online learning program or a blended learning approach makes calculating ROI an easier task. Digital learning programs run through a Learning Management System (LMS) so you can document, track, report, automate and deliver your training program online.

Another consideration is learning content, when done well, can be used for years after the program launch. This long-term usage of learning content makes an ROI calculation more favourably than single-use learning content such as traditional classroom-based learning.

Summary

It is essential for any learning program to demonstrate value for the business with both tangible and intangible benefits. Predicting ROI to ensure the program is approved and then measuring and reporting ROI to establish it as part of your ongoing learning strategy is challenging but achievable with the right support and approach.

Digital learning via an LMS undoubtedly makes measuring and reporting hard data easier. It also means the system administrator has a wider choice of data to track and report on.

The global workforce is continually evolving. A multigenerational workforce and a shorter shelf life for knowledge have placed a premium on reskilling and upskilling. It means there is ever-increasing importance on attracting, nurturing, and retaining the best talent for your organisation.

The LMS offers your end users a centralised place for learning content to ensure seamless learning is accessible anytime and anywhere. Administrators can create personalised learning courses or learning journeys for individuals, teams or company-wide and track and report on progress using their choice of metrics.

With 90%+ of Fortune-500 organizations running SAP to manage their mission-critical business processes and considering the much-enhanced risk of cyber-security breach in today’s volatile and tech-savvy geo-socio-political world, security of your SAP systems deserves much more serious consideration than ever before.

The incidents like hacked websites, successful Denial-of-Service attacks, stolen user data like passwords, bank account number and other sensitive data are on the rise.

Taking a holistic view, this article captures possible ways, remediation to plug in all the possible gaps in various layers. (Right from Operating system level to network level to application level to Cloud and in between). The related SAP products/solutions and the best practices are also addressed in the context of security.

1. Protect your IT environment

Internet Transaction Server (ITS) Security

To make SAP system application available for safe access from a web browser, a middleware component called Internet Transaction Server (ITS) is used. The ITS architecture has many built-in security features.

Network Basics (SAP Router, Firewalls and Network Ports)

The basic security tools that SAP uses are Firewalls, Network Ports, SAP Router. SAP Web dispatcher and SAP Router are examples of application level gateways that can be used for filtering SAP network traffic.

Web-AS (Application Server) Security

SSL (Secure Socket Layer), is a standard security technology for establishing an encrypted link between a server and client. SSL authenticates the communication partners(server & client), by determining the variables of the encryption.

2. Operating System Security hardening for HANA

SAP pays high attention on the security topic. At least as important as the security of the HANA database is the security of the underlying Operating System. Many hacker attacks are targeted on the Operating System and not directly on the database. Once a hacker gained access and sufficient privileges, he can continue to attack the running database application.

Customized operating system security hardening for HANA include:

• Security hardening settings for HANA
• SUSE/RHEL firewall for HANA
• Minimal OS package selection (The fewer OS packages a HANA system has installed, the less possible security holes it might have)

For any server hardening, following procedure is used –

• Benchmark templates used for hardening
• Hardening parameters considered
• Steps followed for hardening
• Post-hardening test by DB/application team

The above procedures should help SAP customers in securing their servers (mostly on HP UNIX, SUSE Linux, RHEL or Wintel) from threats, known/unknown attacks and vulnerabilities. It also adds one more layer of security at the host level.

3. SAP Application (Transaction-level security)

SAP Security has always been a fine balancing act of protecting the SAP data and applications from unauthorized use and access and at the same time, allowing users to do the transactions they’re supposed to.  A lot of thinking needs to go in designing the SAP authorization matrix taking into account the principle of segregation of duties. (SoD)

The Business Transaction Analysis (Transaction code STAD) delivers workload statistics across business transactions (that is, a user’s transaction that starts when a transaction is called (/n…) and that ends with an update call or when the user leaves the transaction) and jobs. STAD data can be used to monitor, analyse, audit and maintain the security against unauthorized transaction access.

4.   SAP GRC

SAP GRC (Governance, Risk & Compliance) , a key offering from SAP has following sub-modules:

Access control

SAP GRC Access Control application enables reduction of access risk across the enterprise by helping prevent unauthorized access across SAP applications and achieving real-time visibility into access risk.

Process control –

SAP GRC Process Control is an application used to meet production business process and information technology (IT) control monitoring requirements, as well as to serve as an integrated, end-to-end internal control compliance management solution.

Risk Management

• Enterprise-wide risk management framework
• Key risk indicators, automate risk alerts from business applications

5. SAP Audit –

AIS (Audit Information System) –

AIS or Audit Information System is an in-built auditing tool in SAP that you can use to analyse security aspects of your SAP system in detail. AIS is designed for business audits and systems audits. It presents its information in the Audit Info Structure.

Besides this, there can be license audit by SAP and or by the auditing firm of your company (like Deloitte/PwC).

Basic Audit

Here the SAP auditors collaborate strongly with a given license compliance manager who is responsible for ensuring that the audit activities correspond with SAP’s procedure and directives. The number of basic audits undertaken is subject to SAP’s yearly planning, and it is worth noting that not all customers are audited annually.

The auditors perform below tasks (though they will vary a bit from organization to organization & from auditor to auditor):

• Analysis of the system landscape to make sure that all relevant systems (production and development) are measured.
• Technical verification of the USMM log files: correctness of the client, price list selection, user types, dialog users vs. technical users, background jobs, installed components, etc.
• Technical verification of the LAW: users’ combination and their count, etc.
• Analysis of engine measurement – verification of the SAP Notes
• Additional verification of expired users, multiple logons, late logons, workbench development activities, etc.
• Verification of Self Declaration Products, HANA measurement and Business Object.

SAP Enhanced Audit –

Enhanced audit is performed remotely and/or onsite and is addressed to selected customers. Besides the tasks undertaken in ‘Basic Audit’, it additionally covers –

• Checking interactions between SAP and non-SAP systems
• Data flow direction
• Details of how data is transferred between systems/users (EDI, iDoc, etc)

6. Security in SAP S/4 HANA and SAP BW/4 HANA

SAP S/4 HANA & SAP BW/4 HANA use the same security model as traditional ABAP applications. All the earlier explained components/security solutions are fully applicable in S/4 HANA as well as BW/4 HANA.

But these are increased security challenges posed by its component, SAP Fiori, which brings in mobility. But increased mobility means that data can be transferred over a 4G signal, which is not as secure and is easier to hack into. If a device falls into the wrong hands, due to theft or loss, that person could then gain unlawful access to your system. Its remediation is elaborated next.

7. Security in Fiori

While launching SAP Fiori app, the request is sent from the client to the ABAP front-end server by the SAP Fiori Launchpad via Web Dispatcher. ABAP front-end server authenticates the user when this request is sent. To authenticate the user, the ABAP front-end server uses the authentication and single sign-on (SSO) mechanisms provided by SAP NetWeaver.

Securing SAP Fiori system ensures that the information and processes support your business needs, are secured without any unauthorized access to critical information.

The biggest threat for an SAP app is the risk of an employee losing important data of customers. The good thing about mobile SAP is that most mobile devices are enabled with remote wipe capabilities. And many of the CRM- related functions that organizations are looking to use on mobile phones, are cloud-based, which means the confidential data does not reside on the device itself.

SAP Afaria, one of the most popular mobile SAP security providers, is used by many large organizations to enhance the security in Fiori. It helps to connect mobile devices such as smartphones and tablet computers. Afaria can automate electronic file distribution, file and directory management, notifications, and system registry management tasks. Critical security tasks include the regular backing up of data, installing patches and security updates, enforcing security policies and monitoring security violations or threats.

8. SAP Analytical Cloud (SAC)

SAP Analytics Cloud (or SAP Cloud for Analytics) is a software as a service (SaaS) business intelligence (BI) platform designed by SAP. Analytics Cloud is made specifically with the intent of providing all analytics capabilities to all users in one product.

Built natively on SAP HANA Cloud Platform (HCP), SAP Analytics Cloud allows data analysts and business decision makers to visualize, plan and make predictions all from one secure, cloud-based environment. With all the data sources and analytics functions in one product, Analytics Cloud users can work more efficiently. It is seamlessly integrated with Microsoft Office.

SAP Analytical Cloud use the same security model as traditional ABAP applications.

The concept of roles, users, teams, permissions and auditing activities are available to manage security.

9. Identity Management

SAP Identity Management is part of a comprehensive SAP security suite and covers the entire identity lifecycle and automation capabilities based on business processes.

It takes a holistic approach towards managing identities & permissions. It ensures that the right users have the right access to the right systems at the right the time. It thereby enables the efficient, secure and compliant execution of business processes.

10. IAG – (Identity Access Governance) for Cloud Security

SAP Identity Access Governance (IAG) is a multi-tenant solution built on top of  SAP Business Technology Platform (BTP) and SAP’s proprietary HANA database. It is SAP’s latest innovation for Access Governance for Cloud.

It provides out of the box integration with SAP’s latest cloud applications such as SAP Ariba, SAP Successfactors, SAP S/4HANA Cloud, SAP Analytics Cloud and other cloud solutions with many more SAP and non-SAP integrations on the roadmap.

11. SAP Data Custodian

To allay the fears of data security in SAP systems hosted on Public Cloud, SAP introduced its latest solution called ‘SAP Data Custodian’.  It is an innovative Governance, risk and compliance SaaS solution which can give your organization similar visibility and control of your data in the public cloud that was previously available only on-premise or in a private cloud.

• It allows you localize your data and to restrict access to your cloud resources and SAP applications based on user context including geo-location and citizenship
• Restricts access to your data, including access by employees of the cloud infrastructure provider 
• Puts encryption key management control in your hands and provides an additional layer of data protection by segregating your keys from your business data
• Uses tokenization to secure sensitive database fields by replacing sensitive data with format-preserving randomly generated strings of characters or symbols, known as tokens
• With data discovery you can scan for sensitive data categories such as SSN / SIN, national ID number, passport number, IBAN, credit card, email address, ethnicity, et cetera, based on pattern determination and machine learning

12. Futuristic approach towards securing ERP systems

Driven by the digital transformation of businesses and its demand for flexible computing resources, the cloud has become the prevalent deployment model for enterprise services and applications introducing complex stakeholder relations and extended attack surfaces.

Mobility (access from smart phones/tablets) & IOT (Internet of things) brought in new challenges of scale (“billions of devises”) and required to cope with their limited computational and storage capabilities asking for the design of specific light-weight security protocols. Sensor integration offered new opportunities for application scenarios, for instance, in distributed supply chains.

Increased capabilities of sensors and gateways now allow to move business logic to the edge, removing the backend bottleneck for performance.

SAP has been investing a lot in drawing, refining its roadmap for security for the future.

It used McKinsey’s 7S strategy concept to review SAP Security Research and adapt supporting factors. Secondly, it assessed technology trends provided by Gartner, Forrester, IDC and others to look into probable security challenges.

As per SAP’s research, today’s big challenges in cybersecurity emanate around ML (Machine Learning). The trend is ML anywhere! ML itself provides a new attack vector which needs to be secured. In addition, ML is used by attackers and so needs to be used by us to better defend our solutions.

Machine Learning that has the most significant impact on the security and privacy roadmap these days, both providing the power of data to design novel security mechanisms as well as requiring new security and privacy paradigms to counter Machine Learning specific threats.

Deceptive applications is another trend SAP foresees. Applications must be enabled to identify attackers and defend themselves.

Thirdly, still underestimated, SAP foresees the attacks via Open Source or Third-party software. SAP has been adapting its strategy accordingly to tackle those new trends.

Wishing all SAP Customers a Happy, Safe and Compliant SAP experience!

During this period, you can start the replication of your source machines, launch target machines, conduct unlimited tests, and perform a scheduled cutover to complete your migration.

This blog exclusively covers the options available in AWS to recover SAP HANA Database with low cost and without using native HSR tool of SAP. With a focus on low costs, Sify recommends choosing a cloud native solution leveraging EC2 Auto Scaling and AWS EBS snapshots that are not feasible in an on-premises setup.

Solution Overview

The Restore process leveraging Auto Scaling and EBS snapshots works across availability zones in a region. Snapshots provide a fast backup process, independent of the database size. They are stored in Amazon S3 and replicated across Availability Zones automatically, meaning we can create a new volume out of a snapshot in another Availability Zone. In addition, Amazon EBS snapshots are incremental by default and only the delta changes are stored since the last snapshot. To create a resilient highly available architecture, automation is key. All steps to recover the database must be automated in case something fails or goes wrong.

Autoscaling Architecture

The following diagram shows the Auto Scaling architecture for systems in AWS.

Use Case

EBS Snapshots

Prior to enabling EBS snapshots we must ensure the destination of log backups are written to an EFS folder which is available across Availability Zones.

Create a script prior to the command to be executed for an EBS snapshot. By using the system username and password, we make an entry into the HANA backup catalog to ensure that the database is aware of the snapshot backup. We use the snapshot feature to take a point in time and crash consistent snapshot across multiple EBS volumes without a manual I/O freeze. It is recommended to take the snapshot every 8-12 hours.

Now the log backups are stored in EFS and full backups as EBS snapshots in S3 and both sets are available across AZs. Both storage locations can be accessed across AZs in a region and are independent of an AZ.

EC2 Auto Scaling

Next, we create an Auto Scaling group with a minimum and maximum of one instance. In case of an issue with the instance, the Auto Scaling group will create an alternative instance out of the same AMI as the original instance.

We first create a golden AMI for the Auto Scaling group and the AMI is used in a launch configuration with the desired instance type. With a shell script in the user data, upon launch of the instance, new volumes are created out of the latest EBS snapshot and attached to the instance. We can use the EBS fast snapshot restore feature to reduce the initialization time of the newly created volumes.

If the database is started now (recently), it would have a crash consistent state. In order to restore it to the latest state, we can leverage the log backup stored in EFS which is automatically mounted by the AMI. Additional Care to be taken so that the SAP application server is aware of the new IP of the restored SAP HANA database server.

Benefits

• Better fault tolerance – Amazon EC2 Auto Scaling can detect when an instance is unhealthy, terminate it, and launch an instance to replace it. Amazon EC2 Auto Scaling can also be configured to use multiple Availability Zones. If one Availability Zone becomes unavailable, Amazon EC2 Auto Scaling can launch instances in another one to compensate.
• Better availability – Amazon EC2 Auto Scaling helps in ensuring the application always has the right capacity to handle the current traffic demand.
• Better cost management – Amazon EC2 Auto Scaling can dynamically increase and decrease capacity, as needed. Since AWS has pay for the EC2 instances, billing model can be used to save money, by launching instances only when they are needed and terminating them when they aren’t.

Conclusion

This blog discussed how Sify can help SAP customers to save cost by automating recovery process for HANA database, using native AWS tools. Sify would be glad to help your organization as your AWS Managed Services Partner for a tailor-made SAP on AWS Cloud solution involving seamless cloud migration experience and for your Cloud Infrastructure management thereafter.

Cloud computing (which later became known as just Cloud), one of the technology trends since last few years, has become a game-changer. Cloud offered a platform for organizations not just to host their applications but also to maintain it / manage it and charge organizations on a pay-per-usage model. This translated into getting rid of the Capex (Capital expenditure on hardware/servers) and instead, opting for the flexible Opex (Operating Expenses) model which also helped organizations in slashing the manpower budget.

The biggest advantage of Cloud is its scalability – freedom to add/reduce storage/compute/network bandwidth as per the need within an agreed SLA-framework.

The rise of Cloud adoption led to two categories:

• Cloud as a hosting platform
• Cloud-based software/applications

Cloud as a hosting platform

This is more popularly known as Platform-as-a-Service (PaaS) or Infrastructure-as-a-Service (IaaS) wherein the service provider offers bundled services of Compute, Storage, Network & Security requirements.

Cloud providers deliver a computing platform, typically including operating system, programming language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers.

Based on the deployment options, Cloud is classified under Public, Private and Hybrid Cloud, which vary due to security considerations.

Why AWS

With some PaaS providers like AWS, the underlying compute and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually. They use a load balancer which distributes network or application traffic across a cluster of servers. Load balancing improves responsiveness and increases availability of applications.

As per a 2020 IDC study, over 85% of customers report cost reduction by running SAP on AWS.

Get consulting support, training, and services credits to migrate eligible SAP workloads with the AWS Migration Acceleration Program (MAP).

AWS has been running SAP workloads since 2008, meaningfully longer than any other cloud provider. AWS offers the broadest selection of SAP-certified, cloud-native instance types to give SAP customers the flexibility to support their unique and changing needs.

Whether you choose to lift and shift existing investments to reduce costs, modernize business processes with native AWS services, or transform on S/4HANA, reimagining is possible with SAP on AWS.

When you choose AWS, you will be joining 5,000+ customers who trust the experience, technology, and partner community of AWS to migrate, modernize, and transform their SAP landscapes.

AWS & Sify collaboration

While AWS has been a global leader in Public Cloud services, in India Sify Technologies (one of the pioneers in the ICT domain & India’s first SSAE-16 Cloud certified provider) had designed its own Cloud called ‘CloudInfinit’ way back in 2013 and since then has been helping diverse organizations in moving their ERP applications, especially SAP workloads to its Cloud, seamlessly.

SAP SYSTEMS monitoring

Once SAP workloads are moved to AWS, Sify’s Managed Services takes care of every aspect, including monitoring the Operating System, Database, Connectivity, Security, Backup etc. as per the agreed SLAs. It also monitors the mission-critical SAP systems closely as depicted in diagram below.

Conclusion

Cloud, the scalable, flexible and yet robust hosting platform allows you to use your ERP workloads as well as SaaS applications effectively. Going by the increasing number of customers moving to Cloud, it is certain that Cloud is not vaporware, it is here to stay and only to grow bigger and safer by the day! It would also necessitate organizations to chart out a Smart Cloud strategy.

According to Gartner, most of midsize and enterprise customers will be adopting a hybrid or a multi-cloud strategy. Companies have already realized that in order to move to public cloud, it is important to structure workload in hybrid cloud model.

Companies must understand that hybrid IT is not an easy methodology and therefore they must organize their existing IT resources and application workloads both on-premises and in public cloud efficiently to accomplish the goals of hybrid model. Additionally, they must also look for right skills for different private/public clouds and different sets of tools from respective cloud providers.

At Sify, we define some guidelines and structure to right fit your workloads in Hybrid Cloud. Please read on to know how Sify can help customers identify the right cloud (from the set of appropriate private and/or private clouds) for different sets of workloads.

Unique Challenges in Hybrid Cloud

In hybrid cloud, there are some unique challenges that businesses need to address first. key challenges that need to be addressed while designing solution on Hybrid Cloud are mentioned herein.

• Generally, it is very difficult to identify the most suitable cloud environment and manage the cost of different clouds.
• Though all cloud environments are powerful in providing features like scalability and elasticity, however the process of managing a hybrid cloud is quite a complex task.
• Security Risks: The threat of data breach or data loss is perhaps the biggest challenge faced during hybrid cloud adoption. Generally, companies prefer on-premises private cloud to protect data locally. However, in order to ensure top-tier security of data and applications on hybrid cloud, companies must draft robust data protection policies and procedures.

Identify Applications for Hybrid Cloud

It is very important to identify applications for hybrid cloud, and your decision must be based on application’s architecture, behavior and user accessibility. Below are some key points to remember while designing Hybrid Cloud strategy: –

• Consider the compatibility of applications before deciding whether you want to continue running the applications in an on-prem cloud environment or migrate them to Public Cloud.
• Identify the running cost/budget for an application and compare it with different cloud providers to choose the most suitable cloud platform that suits your budgetary outlines and business requirements.
• Pay due attention to licensing requirements before migrating to Public/Private Cloud because a minor loophole in this aspect can have a major impact on the overall business.
• Re-look experience of existing IT team to manage different Private/Public cloud seamlessly.

Why VMC on AWS as Hybrid Cloud Choice?

VMware Cloud (also called as VMC) on AWS brings VMware’s enterprise-class Software-Defined Data Centre software to the AWS Cloud and enables customers to run production applications across VMware vSphere-based private, public, and hybrid cloud environments, with optimized access to AWS services.

AWS is VMware’s preferred public cloud partner for all vSphere-based workloads. The VMware and AWS partnership delivers a faster, easier, and cost-effective path to the hybrid cloud while allowing customers to modernize applications enabling faster time-to-market and increased innovation.

New Amazon EC2 i3en.metal instances for VMware Cloud on AWS, powered by Intel Xeon Scalable processors, deliver high networking throughput and lower latency so you can migrate data centres to the cloud for rapid data centre evacuation, disaster recovery, and application modernization.

VMC on AWS can be the right choice because VMware is trusted as a trusted virtualization platform for many years in the industry and enterprise VMware ensures that all your applications run seamlessly. Plenty of companies are already running on VMware platform and have applications running on it. Below are some key identifiers for VMC on AWS:

• VMware SDDC is running on bare metal, which is delivered, operated, supported by VMware
• On-demand scalability and flexible consumption
• Full operational consistency with on-premises SDDC
• Seamless workload portability and hybrid operations
• Global AWS footprint, reach, and availability
• Native AWS services accessibility

How VMC on AWS Solution Works?

VMware Cloud on AWS infrastructure runs on dedicated, single tenant hosts provided by AWS in a single account. Each host is equivalent to an Amazon EC2 I3.metal instance (2 sockets with 18 cores per socket, 512 GiB RAM, and 15.2 TB Raw SSD storage). Each host is capable of running many VMware Virtual Machines (tens to hundreds depending on their compute, memory and storage requirements). Clusters can range from a minimum 3 hosts up to a maximum of 16 hosts per cluster. A single VMware vCenter server is deployed per SDDC environment.

How do We Access AWS Services?

For companies that are using VMware Cloud on AWS (VMC) as production environment for their business-critical application, it will require connectivity to an AWS account. This is enabled by an AWS elastic network interface which provides a 25Gbps connectivity between VMC and AWS. Applications deployed on VMC can leverage native AWS services for storage, EC2 instances, RDS Databases, load balancing and DNS routing, etc., providing customers with the best of both worlds. These native services can be accessed from applications deployed on VMC and include:

• Simple Storage Service (S3)
• Elastic File Service (EFS)
• Amazon Relational Database Service (RDS)

With the increased demand in scalability and flexibility of the infrastructure for organization to ramp up and speed up the go-to-market approach, it has become necessary to adopt the Public Cloud which can tackle this challenge efficiently. Therefore, businesses are looking for simple, reliable, and rapid migration of on-premises workload to Public Cloud with minimal disruption. Sify, being an AWS Advance Partner, has successfully carried out many large cloud migrations for several customers using CloudEndure and the best practices it brings in.

CloudEndure is a SaaS service offering from AWS to migrate workload from any source (physical, virtual, or private/public cloud) to AWS, from one AWS region to other AWS account (within same Account), and across different AWS accounts. It uses block level continuous replication to replicate data on to the target AWS environment.

To replicate data from source machine to target machine, we need to install agent on the source machine and should have the required CloudEndure license for migration. The migration license has expiry date post which the data replication stops.

The Continuous Data Replication task is performed and pushed to the staging area (includes Replication Server, EBS Volume, S3 Storage, Subnets and IP). The CloudEndure Service Manager ensures the co-ordination among the Source Machine, Replication Server and the Target Server.

Three points of contact for CloudEndure’ s components with the external network:

• The CloudEndure Agent needs to communicate with the CloudEndure Service Manager.
• The CloudEndure Agent needs to communicate with the CloudEndure Replication Servers.
• CloudEndure Replication Servers need to communicate with the CloudEndure Service Manager and S3.

CloudEndure helps you overcome below migration challenges effectively:

• Diverse infrastructure and OS type
• Legacy application
• Complex database
• Busy continuously changing workloads
• Machine compatibility issues
• Expensive cloud skills required
• Downtime and performance disruptions
• Tight project timelines and limited budget

Best Migration Practices that CloudEndure recommends:

Planning

• Begin by mapping out a migration strategy that identifies clear business motives and use cases for moving to the cloud.
• Migrate in phases/waves or conduct a pilot light migration in which you start with the least business-critical workloads.
• Do not perform any reboots on the source machines prior to a cutover.
• When scheduling your cutover, ensure that you allow enough time for data replication to complete and for all necessary testing to be carried out.

Licensing

• Ensure that you have sufficient migration licenses for your project.
• CloudEndure Migration license is free for 90 days of use following agent installation on source machine.
• While the use of CloudEndure Migration is free, you will incur charges for any AWS infrastructure that is provisioned during migration and after cutover, such as compute (EC2) and storage (EBS) resources.

Testing

• Check and optimize the network needed for migration.
• Perform a test at least one week before you plan to migrate your source This time frame is intended for identifying potential problems and solving them, before the actual cutover takes place.
• Train the staff early on CloudEndure and mitigate any risk during testing phase only.
• Ensure connectivity to your target machines (using SSH for Linux or RDP for Windows) and perform acceptance tests for your application.

Successful Implementation

• Cutover the machine on planned date.
• Carry out the acceptance test for the application migrated and functionality.
• Remove Source machines from the console after the cutover has been completed in order to clean up the staging area, reduce costs, and remove no longer needed replication resource.

Use cases

The Most Common uses cases for CloudEndure Migration are:

• Lift and Shift, then optimize
• Vast majority of Windows/Linux server when agent can be installed on source machine
• Replicating Block Storage devices like SAN, iSCSI, Physical, EBS, VMDK, VHD
• Replicating full machine/volume

Conclusion

You must keep these above points in mind while migrating to AWS using CloudEndure to reap the desirable outcomes. Sify would be glad to help your organization as your AWS Managed Services Partner for a tailor-made solution involving seamless, cloud migration experience and for your Cloud Infrastructure management thereafter.

Taking steps to meet your legal obligations may sound obvious, but only fulfilling your minimum requirements might result in missed opportunities. Understanding the compliance needs that govern your business will help you take advantage of any benefits while ensuring you stay compliant. Companies that have compliance as a key component of their learning and development culture and have it fully integrated into their business processes will perform better. Why? Their employees have a higher level of satisfaction, resulting in improved productivity and employee retention. Their reputation and brand perception is better, which results in better economic performance in the marketplace. Safety records improve reducing both cost and risk. Companies that do not adopt a compliance culture and ethical behaviour put themselves at risk. Organisations with poor compliance reputations will have a harder time recruiting and retaining the best talent and customers. With global 24/7 news coverage and the reach of social media, word of damaging compliance issues can spread quickly to a large audience. Visit the Financial Conduct Authority website for guidance on money laundering laws and regulations A well-planned compliance strategy can help companies grow revenue in many ways, such as:

• Winning or retaining contracts that have safety or other compliance performance requirements.
• Enhancing brand image and reputation, which may attract more customers.
• Attracting the best talent who want to work for a company with a reputation and culture they can be proud of.
• Motivating employees with training and developing plans to be more productive and enjoy their roles.

6 Factors to Consider Ahead of Your Compliance Journey

1. Get Leadership Buy-in

   Your compliance journey must start with commitment from the leadership team to achieve behaviour change. Executives need to define and own the risk management process.

2. Identify Risks

   Risks to the organisation should be identified and prioritised. High-risk issues will require the greatest commitment to training and to achieve behavioural change. Low-risk issues should receive less attention.

3. Align Risks to Business Goals

   Once the risks have been prioritised, they should be aligned to support key business goals and incorporated into your business strategy. Key goals may include revenue growth, expense reduction, risk reduction, and employee safety. Next, a training program should be planned to train the right people, on the appropriate subjects, in the right way. The learnings from the training should be embedded in the daily routine of employees and practised on the job.

4. Be Strategic with Training

   Many compliance training programs overlook the emotional aspect of training. Emotional training messages help your team feel that the company is looking out for their safety and well-being. By instilling pride in working for an ethical company, employees will stay longer and work harder to support company goals. People enjoy feeling that they are a part of something good that is bigger than themselves. Help employees understand that bad behaviour may have dire consequences.

5. Be Relevant

   Your compliance training program needs to target the right job roles for each training format. Nothing will annoy employees faster than a training course that is of no help to them in their role.

6. Develop Metrics

   Meaningful metrics for the compliance program should be established at the onset. Metrics should be aligned around the key company goals that the compliance program has been designed to support. The compliance program should be implemented in such a way that data for the metrics can be easily collected and reported via a Learning Management System. Targets for the metrics should be realistic and achievable. When targets are unachievable, people are not motivated to reach them.

Conclusion

Your compliance journey is a marathon, not a sprint. It is important to keep your team motivated throughout their learning experiences to keep the momentum going. Here are some ideas to consider:

• Share success stories with your employees of how your compliance program has succeeded in helping the company reach its goals.
• Tell the outside world about your compliance program successes. This will help enhance the reputation and brand perception of your organisation and help recruit the best talent.
• Empower your employees. Provide a Learning Management System that provides easy access to digital learning content that will help them in their jobs.
• Create learning experiences that are engaging and maximise learning technologies to provide high-quality content.
• Proactively seek feedback and survey, listen to the concerns of employees, and act quickly to respond to needs.

The benefits of strategically using compliance to support business objectives are clear. A people-centric compliance culture can help organisations reach important goals, such as revenue growth, cost and risk reduction, and improved safety. The risks of failing to adopt a compliance culture can be severe.
