What are the 7 key strategies of application modernization transformation, commonly known as the 7 R’s?

  • Retain: This strategy involves keeping existing applications or systems as they are, without making any significant changes. It may be suitable for applications that still meet business needs effectively and do not require immediate modernization.
  • Rehost: Also known as “lift and shift,” this strategy involves moving existing applications to a new environment without making changes to their code. It can be a quick and cost-effective way to migrate applications to the cloud or newer infrastructure.
  • Replatform: In this strategy, applications are moved to a new platform or environment with minimal changes to their code. It often involves updating underlying components or dependencies to leverage the benefits of the new platform, such as improved performance or scalability.
  • Refactor: Refactoring involves making significant changes to the codebase of existing applications to modernize their architecture, improve performance, or enhance scalability. It may involve restructuring code, adopting new development patterns, or incorporating modern technologies.
  • Repurchase: This strategy involves replacing existing applications with commercial off-the-shelf (COTS) software or Software as a Service (SaaS) solutions. It can be a viable option when existing applications no longer meet business requirements or when it’s more cost-effective to adopt pre-built solutions.
  • Relocation: Relocation involves moving applications or systems to a different physical location or data center. It may be necessary to improve performance, reduce latency, or comply with regulatory requirements.
  • Retire: This strategy involves decommissioning or retiring outdated or redundant applications or systems that are no longer needed. It helps streamline the IT landscape, reduce maintenance costs, and simplify management.
