Strategies How to Migrate Existing Applications to Microservices

Another set of how to migrate monolithic(Existing) application to microservices, an easy and simple steps design by DEV IT expert.

Monolithic application is set of modules, business process, and all functionality in one set and various database related operation. it is easy to test and only one application to release all time.

But the main issue with monolithic application is to scaling up, because whenever any bug occurs you have to check entire system and solve it out and redeploy it and that takes much time of developer.

So, as the technology evolved developers has found the way to develop all require module into separate way as they deploy separately and easy to manage while any bug occurs and its called microservices.

migrating monolithic(existing) application to microservices require proper planning by an expert Below I have mentioned few practical strategies which helps to developer.

1. Make a good transition plan
2. Identify all logical modules and most independent modules.
3. Identify inter-system relationships.
4. Identify groups of modules.
5. Prepare an individual service-wise database.
6. Never allow migrated-service code to again fall in the monolith app.
7. Migrate module groups to separate services and make separate deployments.
8. You can also break an existing microservice into smaller ones.Make use of the event bus to communicate between microservices.
