- Rehosting (Lift and Shift): Moving applications to the cloud with minimal or no modifications. This approach is quick and cost-effective but may not fully utilize cloud-native features.
- Refactoring: Modifying applications to better fit the cloud environment, often by breaking them into microservices. This enhances scalability and performance but requires more effort and resources.
- Replatforming: Making minimal changes to applications to optimize them for the cloud without altering their core architecture. This balances efficiency and resource investment.
- Repurchasing: Replacing existing applications with cloud-based solutions, such as Software as a Service (SaaS) offerings. This can streamline operations but may involve data migration challenges.
- Retiring: Identifying and decommissioning applications that are no longer useful, reducing complexity and costs.
- Retaining: Keeping certain applications on-premises, especially if they have recently been upgraded or if there are compelling reasons to maintain them in their current environment.
