Microservices with gRPC [Java + Spring Boot + Protobuf]

gRPC is one of the hottest technologies in the recent years from Google for designing highly performant and scalable APIs for your Microservices. By using gRPC, you can have 10X performance compared to traditional REST based microservices communication. It is very very fast!

It allows us to choose different types of APIs depending on our use case which is not possible with REST. One of the biggest challenge in Microservices design is inter-services communication. Most of the developers use REST as it is general-purpose. But It has a lot of challenges. We would be learning how to solve the common problems with REST by using gRPC.

By the end of this course, You would be comfortable with,

• Microservices development with gRPC
