Late last year, Broadcom acquired VMware for more than $60 billion, and shortly after, the company announced it would be moving entirely to a subscription model.
For many existing VMware users, this was terrible news since details of the new model made it clear that the valuable tool would eventually become far too expensive for all but the most prominent companies.
While the VMware subscription model switch came with a three-year grace period, depending on when customers last signed their agreement, the writing is on the wall that companies unable—or unwilling—to pay up needed to find an alternative.
The good news is that alternatives are available. We recommend that our clients move their workloads to AWS when they are already primarily using the platform.
Transitioning from VMware to AWS requires careful planning and execution to ensure a smooth and successful migration.
All told, there are six steps we generally take when helping companies make the switch. These are:
Understanding the current infrastructure of your VMware environments will help determine the best migration strategy and identify potential challenges. Key areas to focus on include:
Once your VMware environment has been assessed, you should select a migration strategy. AWS offers several migration paths, each with different levels of complexity and benefits. Your plan depends on your needs, timelines, and risk tolerance.
Lift-and-shift involves migrating VMware workloads to AWS with minimal changes to the underlying architecture. This is the fastest and most straightforward method since workloads are rehosted on AWS without modifying the applications or virtual machines. Tools like AWS Application Migration Service or third-party solutions like CloudEndure can help automate migration. This strategy is ideal for businesses looking for a quick migration with minimal upfront investment.
In a re-platforming migration, applications are partially modified to take advantage of specific AWS services, but the core architecture remains intact. For example, you may move from VMware-based databases to Amazon RDS or shift storage to Amazon S3. This strategy requires more effort than lift-and-shift but allows you to leverage AWS-native services to improve performance and reduce costs.
Refactoring involves re-architecting applications to fully leverage the benefits of cloud-native services. This often requires significant changes to application code and architecture. While this approach demands more time and resources, it offers the most significant long-term benefits regarding scalability, performance, and cost-efficiency.
A successful migration to AWS requires careful planning and execution in phases. Attempting to move all workloads simultaneously can lead to unexpected downtime, disruptions, and operational challenges. Common phases include:
Proof of Concept (POC)
Start by selecting a few non-critical workloads or applications for a proof-of-concept migration. This will allow the team to test the migration process, identify potential issues, and refine the approach before moving critical workloads.
Pilot migration
After the POC, move a small set of critical workloads in a pilot phase. This will allow you to fine-tune the migration process, address any performance or compatibility issues, and ensure minimal disruption to business operations.
Full-scale migration
Once the POC and pilot migrations are successful, it’s time to migrate the remaining workloads. Depending on the size and complexity of the VMware environment, this may need to be broken into further phases to minimize risk and downtime.
AWS has put a lot of work into creating several services and solutions that make the migration of VMware workloads easier. Some of their key offerings include:
Security is a critical aspect of any migration to AWS. VMware environments are often heavily customized with specific security controls, and businesses need to maintain or enhance these controls during the transition.
Key considerations include:
Thorough testing is essential to ensure that everything is functioning as expected. Performance, compatibility, and security should all be evaluated.
Look, migrating from VMware to AWS can be a complex process. But with careful planning, the right tools, and a phased approach, you can ensure a smooth and successful transition.
