Application Refactoring is the process of restructuring an existing application's computer code without changing its intended function with the expectation of improved performance, code maintenance and security.
This process is also referred to as refactoring migration as it is typically undertaken so the application can run in a cloud environment.

A business may consider refactoring as a viable approach if it wants to tap cloud benefits, scale or restructure code, and boost the application's agility.
