Distributed systems have become essential in the modern software landscape. They enable services to scale, handle large amounts of data, and provide high availability. This article will guide you through building a simple distributed system in Golang, utilizing a Master Node and a single Worker Node that communicates using the gRPC protocol.
This architecture is ideal for distributed tasks such as data processing, parallel computation, and large-scale processing workloads. We’ll cover setting up a Master and Worker structure, establishing gRPC-based communication, and implementing a simple job assignment and execution flow.
The first step in creating a gRPC-based distributed system is defining the gRPC service and messages in a .proto file. This file outlines the services, RPC methods, and message structures for communication.
We set up a gRPC server to report status and continuously send client tasks via a command channel. It uses Go’s concurrency features to handle real-time command notifications.
