In applications that have been developed by the modern practices of developing small microservices, hosting them over the enterprise infrastructure, and then integrating them together to talk to each other, we can no longer use the traditional approaches we were familiar with during the times of running and maintaining large monolithic applications or services. Let's first take some time to understand why point-to-point integration might not work in the case of microservices.
In the point to point integration approach for microservices, we make the microservices interact with each other directly through the APIs exposed by them. For this to happen, each microservice needs to have the knowledge about the endpoints exposed by the other service. This is perfectly fine, but what happens if the microservice has to do some operation that depends on interaction with five other microservices?
At this point, we...
