Many even call it a hybrid model. Speaking technically, it is not migration application but keeps some standard alone workloads.


For some of the complex application architectures, a few components are easily turned off without affecting the productivity of the application. This case comes into action when the migration application is tough, and you need to delete some duplicate features in order to ease the process.
