Remote Procedure Invocation Design Pattern for Microservices Explained with Examples
In this video we will learn about Remote Procedure Invocation design pattern for microservices interaction with the real-world examples. This is a type of communication design pattern for microservices.
Microservice often intercommunicate with multiple microservices in order to complete complex functionality. Therefore, we can use an inter-process communication protocol for microservice communication. The solution is to leverage the RPI for any inter-service communication and collaboration.
In this solution, the client uses the request-reply-based protocol to make requests to a service. The well-known RPI technologies include REST, gRPC, and Apache Thrift. This pattern is easy to implement and there is no need for any intermediate broker for the communication.
Service uses RPI for inter-process communication to collaborate & to serve the requests. Clients and servers are stubbed so that remote procedure call would seem like local procedure calls.
Remote Procedure Call is an inter-process communication technique used to construct distributed and client-server applications. It is also known as a subroutine call or a function call.
We use remote procedure call (RPC) when they are multiple, independent applications and want to share data or orchestrate cross-application processes. We often use this pattern to build solutions based on Service Oriented Architecture (SOA).
** Usage of this Design Pattern **
1. Use this pattern when multiple, independent applications wants to share data.
2. Use this pattern when multiple, independent applications wants to orchestrate cross-application processes.
** Advantages of this Design Pattern **
1. Simple and familiar technology.
2. Request/reply is easy to manage.
3. Simple architecture as there is no need of intermediate broker.
