An application must meet certain requirements to be considered a good candidate for migration to the cloud. Most endeavor IT shops have more than 1,000 applications they should comprehend or relearn before moving any of them to the cloud. You simply can't move your applications all at once.
Before you make your turn, ensure you've truly thoroughly considered the majority of the key contemplation: What's in it for your business?

In short, how can you transform this initiative from a source of heartburn into a source of new business advantages? Here is some practical advice for moving apps to the cloud.
On the off chance that you found a current cloud-based application that gives the usefulness you required, you could essentially utilize it on a membership or pay-as-you-go premise (Software as a Service, or SaaS).

2- Then there's partial refactoring, where you change as little of the code and data as you can, but build in cloud-native awareness where it improves the application's capabilities or effectiveness, but mainly has the application do what it always has done.
3-Finally, there's complete refactoring, where you rewrite the application to be as cloud-native as possible. This approach involves building facilities into the applications that scale and provision using native APIs, as well as take deep advantage of other features supported by the native cloud.
