How does REST API Work?

In REST Calls the process is synchronous, which means suppose a service SERV1 is waiting for the response from SERV2 it will wait for an infinite time until it gets the response. Now the problem here is that if for some reason SERV2 is taking way too much time to give a response, so SERV1 keeps on waiting resulting in overall lag in the System or the Application. To overcome this type of situation we use something called Request Timed out. If Timed out time is defined as say 5 seconds, and the repose from a service didn’t come in between that time it will wait no further for the response and terminate the process.

In Microservice architecture, there are multiple microservices available for an application. For the application to work properly necessary services need to communicate with each other. There can be communication of messaging type or REST calls.
