|Lift & shift||Attempting to rehost the legacy application on to the new cloud based infrastructure.||The benefits are limited as code is not modified, but it’s a good starting point to migrate to cloud infrastructure. The original challenges will remain however there will be some benefits from a cloud infrastructure of portability and scalability. There are also no guarantees that the legacy application will behave as expected in the new setup.|
|Refactoring||Attempting to rewrite or restructure the application codebase to benefit from cloud based features.||A complex and potentially expensive approach but it’s the right approach depending on the application so it can benefit from migrating from a monolith to a microservices architecture and this benefiting from cloud features such as containerization and orchestration.|
|Re-platforming||A compromise approach where software development is kept to a minimum to allow the application to work on a cloud infra.||It might be a necessary step if Lift & Shift fails. The purists may not appreciate this approach as it can be considered as a non-ideal compromise and may be fraught with support issues. It might make sense if the legacy application is going to be retired in the short/medium term.|
