Authentication and Authorization in Microservices

Scala, , , ,

Reading Time: 3 minutes Microservices Architecture has been gaining a lot of ground as the preferred architecture for implementing solutions as it provides benefits like scalability, logical and physical separation, small teams managing a part of the functionality, flexibility in technology etc. But these benefits come at a cost of simplicity since microservices are distributed the complexity of managing them increases. One of the key challenges is how to Continue Reading

Why gRPC for Inter-Microservice Communication.

Microservices, Tech Blogs, ,

Reading Time: 3 minutes Hi folks! In this blog we will understand why one should use gRPC for inter-service communication over other RESTful services. What is gRPC?
