Refactoring/Re-architecting
Refactoring involves restructuring and optimizing an application’s code and architecture without changing its external behavior. This is often done to break a monolithic application into microservices to leverage cloud-native capabilities like containers. Re-architecting takes this a step further by materially altering the application’s architecture and code to modernize it.
Rebuilding
Rebuilding or rewriting an application from scratch while preserving its scope and specifications. This is done using cloud-native architectures and technologies for cases where an application requires a complete overhaul to meet current and future needs.
Replacing
Eliminating a legacy application altogether and replacing it with a new custom application or off-the-shelf software package that better aligns with the organization’s needs.
