Minimal downtime during migration
With AWS Application Migration Service, you can maintain normal business operations throughout the replication process. It continuously replicates source servers, which means little to no performance impact. Continuous replication also makes it easy to conduct non-disruptive tests and shortens cutover windows.
AWS Application Migration Service reduces overall migration costs as there is no need to invest in multiple migration solutions, specialized cloud development, or application-specific skills. This is because it can be used to lift and shift any application from any source infrastructure that runs supported operating systems (OS).

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.
CloudEndure Migration software doesn’t charge anything as a license fee to perform automated migration to AWS. Each free CloudEndure Migration license allows for 90 days of use following agent installation. 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.
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.
The following diagram shows the Auto Scaling architecture for systems in AWS.
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.
- 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.

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.
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

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:
- 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.
- 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.
- 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.
- 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.
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
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.
Integrate your Cloud, Core, and Edge
With the advent of IoT, pervasive mobility, and growing cloud service adoption, the network has become increasingly distributed, and the need for faster compute and connectivity at the edge has become more pronounced.
As organizations increasingly drive digital transformation initiatives and adopt hybrid multi-cloud, the network must be rearchitected to support new-age topologies. Hence, Network Transformation gains predominance. Network Transformation and re-architecture must play out at all the 3 points of presence of the Network – at the Network Core, Network Management layer, and the Network Edge.
Let us look at the significance of the Transformation at these 3 layers and the contribution that Sify is bringing at each of these points of presence.
Transformation at the Network Core
With Cloud adoption, Data Center is no more the Core of the network. As enterprises are moving their applications to the cloud on consumption-based models for enhanced business productivity, it has become important to secure connectivity to the Cloud and extend the Quality of Service to a hybrid multi-cloud environment. Hence, the transformation of the network at the Core is essential for improved agility, enhanced productivity, and scalability.
Sify’s Transformation Services at the Core are designed to help customers harness the true potential of cutting-edge cloud, digital, and network technologies.

With our Hyperscale Cloud partnerships and the Cloud Interconnect Networks, combined with expertise to deploy technologies like SDWAN & NFV, we hold a distinct level of expertise in network integration and transformation for a hybrid multi-cloud environment.
Transformation at the Network Management and Control Layer
As networks become more & more complex, organizations nowadays are leveraging multiple network service providers, and they have distributed nature of applications and end-users. This has resulted in a very complex network architecture. Moreover, monitoring and management of these complex and distributed networks and network elements have become very critical. Network Management & Control requires a distinct level of expertise, advanced tools, and automation platforms, and hence makes good business sense to outsource the management to an expert who has the benefit of scale, experience, and toolsets to deliver the same. The customer can in turn focus on his core business.
Empowered with a robust Network Operating Center, Sify offers a wide spectrum of Network Consolidation, Network Transformation, and Operations Outsourcing solutions.

Not only this, but Sify also helps customers in network study & assessment and consulting for Network Re-Architecture and Managed Services.
Transformation at the Network Edge
Network Edge is the bridge between an organization and its end customers to deliver enhanced user experience and employee productivity. It is a strategic gateway to connect widely distributed organizations. The traditional networks cannot accommodate the new IoT devices, sensors, and plethora of Edge devices that are connected and managed at the Edge. Therefore, it is crucial to adopt transformation of the network at the edge to meet the requirements of the end devices and make them an integral part of the Enterprise Networks.
Sify Edge Connect Services include advisory services like an assessment of customer requirement with respect to coverage and performance. Further, we ensure end-to-end implementation of customer’s WiFi network, which includes configuring guest access and incorporating employee authentication & access. Our highly secure platform provides insight into user patterns and analytics such as the location of users, applications browsed, etc. Sify also provides deep visibility and control of the performance and usage of applications. In addition, Sify Edge Services include IoT services and aggregation and integration of the same with the Enterprise Network.
While rearchitecting your network, it is important to include aspects connecting the above three points of presence of users and applications. This will help you architect a network that delivers efficiency and is future-ready. However, the majority of organizations lack the necessary skills and expertise to envision and manage such a complex transformation, and that is where Sify Technologies can be your partner in this transformation journey.

In today’s hyper-connected and fast-paced global marketplace, connectivity is the lifeblood needed to keep businesses running smoothly. Enterprise, small or large, need reliable and fast communication networks to work and grow.
MPLS with its ‘labeling protocol’ provides organizations with a communication network that is completely dependable, fast, flexible and cost effective. The obvious and many benefits of MPLS Connectivity is driving businesses to consider switching to MPLS networks, but with the industry inundated by a wide range of services and management models the process of selecting an MPLS service provider can be long and complicated.
How do you evaluate the various telecom service providers and their offerings to get the best possible solution for your requirements? We list out the 5 key criteria that you need to consider.
Network coverage and reach of the MPLS service provider
The first thing that business need to check, is the network coverage offered by the service provider. Do all your desired locations fall under the network carrier’s footprint and in case you need global connectivity can they offer reliable international coverage? The coverage and reach of the service provider will directly impact issues such as latency, jitter, resilience and cost of the MPLS network.
Network project management and monitoring
Complex networks require constant management to run smoothly. Proactive management can lead to reduced costs and downtimes and enhanced security. Businesses need to understand the details of pricing and the scope of services offered under the head of network management and monitoring services. Do they monitor the entire network? Can they provide managed services to free up IT staff?
Complete MPLS Network Security
Security capabilities of the MPLS service provider need to be scrutinized closely. Businesses need to ensure that service providers are able to support and monitor the entire network closely and provide access to a dedicated security infrastructure including experienced NOC engineers to ensure guaranteed uptime.
Compare SLAs and check references
Another surefire way to assess the capabilities of the service provider is to check the SLAs (Service Level Agreements) offered. While experienced service providers with tested capabilities are usually willing to back their services with SLAs, it pays off to compare SLAs of several MPLS network providers. It is also helpful to look at their existing clients and check references to evaluate their performance.
Class of Service and Quality of Service
Businesses need to evaluate and understand the classes of service (COSs) offered by the carrier. How the carrier consolidates and prioritizes various traffic types will affect the Quality of Service (QoS). It is important that these COSs match your business requirement and the contract with the service provider clearly defines and states these service commitments.
While the above mentioned points form a base to shortlist the right MPLS network provider, other points, such as routing protocols, staff expertise, 3rd party partnerships, network architecture and future scalability capabilities, must also form a part of the decision making process.
Although cost always plays a big role in any business decision, alignment to your business’ current and future needs and long-term goals should be the deciding factor. After all, your MPLS Network will form the backbone of your business for a long time to come.
Sify Technologies is uniquely positioned to cater to the MPLS Virtual Private Network (VPN) connectivity requirements of Large & Emerging Enterprise customers through its SiteConnect™ services which enable cost-effective converged network solutions that enable point to point data, voice and video traffic. Sify’s carrier-grade next-generation network core offers stringent SLA-based converged data, voice and video traffic support.

Hybrid WAN and Application performance-focused Network Architecture:
In the age of hybrid and multi-cloud, it becomes critical for organizations to have a well-thought-out network strategy for distributed workloads, data footprints, applications, services, and microservices. With the rise in multi-cloud adoption, the legacy hub-and-spoke WAN architecture can hold organizations back. The shift from Data Centers towards Cloud has resulted in the more prevalent use of the SLA-defined Internet (in addition to MPLS) as a reliable and pervasive way to establish robust connectivity. Hence, modern-day businesses need a hybrid WAN strategy – the use of internet for business applications along with MPLS. This means the new-age network must enable the hybrid WAN and be smart enough to adapt to the changing application performance demands in a hybrid or multi-cloud environment, ensuring better performance.
Herein, Software Defined Networking can enable fundamental network transformation. SDN can help accomplish the goals of network transformation – agility, flexibility, and application centricity – by intelligently controlling the network architecture using software applications.
- Software Defined Networking facilitates flexible network architectures, which can utilize multiple network connectivity options (MPLS/ILL/BB/4G-LTE/Internet) which help leverage a Hybrid WAN strategy for the evolving DC and Cloud landscape
- SD-WAN ensures application awareness and complete visibility of site-wise utilization of various applications, which paves way for better performance, availability, and security.
- SD-WAN leverages the power of Cloud-based monitoring and management platform for centralized, real-time visibility of all resources.

Centralized visibility, control, and insights of the Network:
Organizations need complete visibility and control over network connectivity to make the most of their Cloud investment. They would also want their network to provide intelligent insights that enable data-driven decision-making. An intelligent network can help businesses with automated and effortless orchestration of network resources. However, enabling a network with comprehensive intelligence is not as simple as it seems, because it requires a well-established network management practice with well-integrated toolsets.
Currently, only a few network service providers, such as Sify Technologies, have the assets, capabilities, and expertise to deliver Intelligent Network Services.
