Embrace the Hybrid Cloud with VMC on AWS


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)
