Cloud Migration Strategies
Rehosting (Lift and Shift)
Rehosting, commonly known as ‘lift and shift,’ involves moving applications and data from an on-premises environment directly to the cloud without modification. This strategy is often favored for its simplicity and speed, allowing organizations to quickly realize the benefits of cloud computing without the complexities of extensive reconfiguration. Rehosting is particularly suitable for organizations that need to scale rapidly or exit a data center, fitting well within various cloud migration models.
Replatforming
Replatforming, sometimes referred to as ‘lift, tinker, and shift’ or ‘lift and reshape,’ involves making optimizations to applications during the migration process to leverage better cloud capabilities. While the core architecture of applications remains the same, some level of cloud optimization is introduced to improve performance or reduce costs. This strategy strikes a balance between the quick and straightforward nature of rehosting and the more intensive demands of refactoring, aligning well with application modernization efforts.
Refactoring
Refactoring, also known as re-architecting, involves significant changes to the application’s design to fully exploit cloud-native features like scalability, elasticity, and serverless computing. This approach is generally the most complex and costly but can yield substantial long-term benefits by aligning applications with the most advanced cloud capabilities. Refactoring is ideal for applications requiring extensive modernization to meet new business demands or technological advancements, making it a key component of cloud migration models and application modernization.
Repurchasing
Repurchasing, often termed ‘drop and shop,’ involves moving to a different product that is cloud-native, typically a SaaS platform. This strategy is beneficial for organizations looking to replace outdated systems with modern cloud solutions without the burden of maintaining legacy software. It allows companies to streamline operations by eliminating the need to manage and upgrade on-premises infrastructure, fitting seamlessly into various cloud migration models.
