When choosing a migration strategy for your application, it's essential to consider various factors such as business objectives, cost savings, scalability, and resource availability. Below are the six common application migration strategies, known as "The 6 R's":
Rehosting (lift-and-shift): migrating applications to the cloud without making significant changes to the architecture. This approach is suitable for organizations seeking a quick migration to the cloud to meet specific business needs.
Replatforming (lift-tinker-and-shift): making some cloud optimizations to an application without altering its core architecture. This strategy allows for cost savings, increased agility, and improved scalability.
Repurchasing: moving from one product to another, often involving the adoption of Software-as-a-Service (SaaS) platforms. This strategy can offer improved functionality, better vendor support, and reduced maintenance efforts.
Refactoring / Re-architecting: involves reimagining an application's architecture and development to leverage cloud-native features fully.
