Microservice pattern: Remote procedure invocation

[iluwatar]

Description

The Microservices - Remote Procedure Invocation (RPI) design pattern is crucial for enabling microservices to communicate effectively in a distributed system. This pattern allows a program to cause a procedure to execute in another address space (commonly on another physical machine). The procedure call is abstracted to appear as a local function call, though it is executed remotely.

Main Elements of the Pattern:

1. Service Definition: Defines the methods and parameters that can be called remotely.
2. Client Proxy: Acts as a local representative for the remote service. It abstracts the complexity of remote communication.
3. Network Protocol: Handles the transmission of requests and responses between client and server.
4. Server Stub: Unpacks the requests, executes the corresponding service methods, and packs the results to be sent back to the client.
5. Serialization/Deserialization: Transforms data structures or objects into a format that can be easily transmitted and reconstructed.
6. Error Handling: Manages issues like network failures, timeouts, and service unavailability.

Acceptance Criteria

1. Implement a basic example of the RPI design pattern demonstrating remote communication between microservices.
2. Include comprehensive unit and integration tests to ensure reliable communication and proper error handling.
3. Update the project documentation to include an explanation of the RPI pattern, its implementation details, and usage instructions.
