Replatforming involves moving an application to a new cloud environment without fundamentally altering its core architecture or code. This process focuses on leveraging cloud capabilities like managed services, scalability, and improved deployment pipelines. It matters because it allows organizations to modernize their infrastructure and gain operational efficiencies without the extensive effort of a complete rewrite. For instance, migrating a monolithic application from on premises servers to a cloud based virtual machine instance while keeping its original structure is a replatforming effort. This differs from refactoring, which involves significant code changes to optimize for the cloud. Replatforming concepts are frequently assessed on cloud security certifications like CCSP and AWS specialty exams.
