What is Replatforming?
Replatforming is a cloud migration strategy in which existing applications are optimized for the cloud with minimal modifications. Unlike simple rehosting (lift & shift), minor changes are made to the application code or architecture. The goal is to leverage the benefits of cloud technologies without completely redeveloping the application.

What does Replatforming mean in practice?

Beim Replatforming wird die Anwendung in die Cloud übertragen und gleichzeitig so angepasst, dass sie besser mit Cloud-Diensten zusammenarbeitet. Typische Optimierungen betreffen die Nutzung von Auto-Scaling, Datenbanken als Service oder Container-Technologien. Wichtig ist, dass die Kernstruktur der Anwendung unverändert bleibt.

When is Replatforming appropriate?

Replatforming is suitable when companies want not only to move their systems but also to modernize them. This approach is particularly useful when an application is intended to operate in the cloud long-term. Replatforming is also a good solution for legacy systems, as it increases performance, reduces costs, and ensures future viability.

Benefits of Replatforming

Better performance: Applications run more stable and faster in the cloud.
Cost efficiency: Optimized resource utilization reduces operating costs in the long term.
Integration of modern services: Easy integration of cloud functions such as serverless computing or containerization.
Lower risks: Since the core architecture remains intact, the migration process is comparatively low-risk.

Challenges and Limitations

Replatforming is more complex than simple rehosting. Companies must possess expertise in cloud technologies and carefully plan the process. Additionally, while the application is optimized, it is not fully cloud-native, meaning some benefits may remain untapped.

Comparison to Other Migration Methods

Rehosting: Fast migration without modifications, but minimal optimization.
Refactoring: Comprehensive adaptation for maximum cloud utilization, but with higher effort.
Replatforming: Middle ground with targeted changes that enable quick results and better scalability.

Conclusion

Replatforming offers a pragmatic approach to migrating applications to the cloud while optimizing them. It combines the benefits of speed and efficiency with the ability to utilize cloud resources more effectively. This makes replatforming an attractive solution for companies that want to modernize their applications without undertaking a complete redevelopment.
