A microservices-based software system requires applications to talk to each other. gRPC is a microservices communication system that is scalable and more efficient than the traditional RESTful services.
gRPC for microservices communication

In the olden days, a software application was built as a large monolith, and It's still being done. However, in recent times microservices architecture has become a popular choice for developing software applications. In a microservice architecture, the microservices often need to communicate with each other. Compared to the traditional RESTful web API, a gRPC based RPC framework can be a better alternative for microservices communication.

Do you want to know more about gRPC, the remote procedure call (RPC) framework used by companies like Netflix and Dropbox?

Let's get started:

What is microservices architecture?

A microservice architecture consists of many (often hundreds) of small, autonomous, self-contained services. A microservice is built around business capability. Some of the important characteristics of microservice architecture are:

Microservices are modeled around business capabilities .

. Microservices are independently deployable .

. A microservices encapsulates the data it owns . In case, if one microservice needs to get data from another microservice then it should call API.

. In case, if one microservice needs to get data from another microservice then it should call API. A microservice should be small in size.

Microservices inter-process communication

A microservices-based software system requires applications to talk to each other using an inter-process communication mechanism. Microservices can communicate with each other as

Synchronous communication (request-reply) : In this pattern, a service calls an API exposed by another service and waits for the response. The API must have well-defined semantics and versioning.

: In this pattern, a service calls an API exposed by another service and waits for the response. The API must have well-defined semantics and versioning. Asynchronous communication: In this pattern, a service sends a message, without waiting for a response from another service. And,…
