Application Modernisation
Definition
Application Modernisation
Application modernisation is the process of updating existing applications so they meet current standards and business requirements. This can include migrating to modern infrastructure, refactoring code, or replacing components with cloud-native alternatives.
In detail
Outdated applications accumulate technical debt, resist change, and create security exposure. Vendors stop releasing patches. Developers avoid touching code they do not understand. The cost of inaction compounds every quarter.
The 6R framework helps determine the optimal path for each workload: Rehost, Replatform, Refactor, Rearchitect, Replace, or Retire. The goal is always the same: reduce operational risk, increase agility, and lower total cost of ownership.
