Thinking of migrating your applications to the Amazon Web Services (AWS) cloud? You’re on the right track! AWS offers scalability, cost-efficiency, and a wide range of services to meet your business needs. But before you dive in, it’s crucial to choose the right migration strategy.

This blog post will guide you through the seven most common AWS migration strategies, also known as the “7 Rs.” We’ll explore what each strategy entails, compare them, and help you decide which one best suits your migration goals.

The 7 Rs of AWS Migration Strategy

  1. Rehost (Lift and Shift): This is the simplest approach, where you essentially “lift and shift” your existing applications to the AWS cloud with minimal modifications. It’s fast and cost-effective but may not leverage the full potential of AWS.
  2. Relocate (Hypervisor-Level Lift and Shift): Similar to rehosting, relocation focuses on migrating virtualized applications using VMware directly to VMware Cloud on AWS. This ensures a smooth transition for existing VMware environments.
  3. Replatform (Lift, Tinker, and Shift): This strategy involves migrating your application to the cloud while making some architectural changes to optimize it for AWS services. You can improve performance and scalability without a complete overhaul.
  4. Refactor (Re-architecting): This is a more involved approach where you completely redesign your application to take full advantage of AWS cloud-native features and services. It offers the most significant benefits but requires considerable development effort.
  5. Repurchase (Drop and Shop): Here, you abandon your existing application and purchase a new, cloud-based solution from a third-party vendor. This can be suitable for outdated applications or if a better solution exists in the cloud marketplace.
  6. Retain: Not all applications need to migrate. Some may be critical for on-premise operations or not suited for the cloud. You can retain these applications on your existing infrastructure.
  7. Retire: If an application is no longer relevant or cost-effective, consider retiring it altogether during your migration process.

How to Choose an AWS Migration Strategy

The best migration strategy depends on several factors, including:

  • Application architecture and complexity
  • Desired level of cloud optimization
  • Budget and resource constraints
  • Timeline for migration

Here are some guiding principles:

  • Start with low-hanging fruit: Consider rehosting or relocating less complex applications first.
  • Refactor strategically: Reserve refactoring for applications that will significantly benefit from cloud-native features.
  • Don’t be afraid to mix and match: You can use different strategies for different applications based on their individual needs.
