Key considerations while adopting microservices

A microservice architecture introduces well-defined boundaries, which makes it possible to isolate failures within the boundaries. But being like other distributed systems, there is likely a chance of failure at the application level. To minimize the impact, we need to design fault-tolerant microservices, which react in a predefined way to certain types of failure. While adapting to microservice architecture, we add one more network layer to communicate with rather than in-memory method calls, which introduces extra latency and one more layer to manage. Given next are a few considerations that if handled with care while designing microservices for failure, will benefit the system in the long run.
