This tutorial will guide you through the basics of Service Discovery in a microservices architecture. Service Discovery is a critical component that allows services to find and communicate with each other dynamically.

Key Concepts

  • Service Registration: When a service starts, it registers itself with a discovery service.
  • Service Discovery: The discovery service maintains a list of available services and provides this information to other services.
  • Service Resolution: When a service needs to communicate with another service, it queries the discovery service to find its location.

How It Works

  1. Service Registration

    • When a service starts, it sends a message to the discovery service with its details, such as its hostname, port, and metadata.
    • Service Registration

  2. Service Discovery

    • The discovery service keeps track of all registered services and provides a list of available services to other services.

  3. Service Resolution

    • When a service needs to communicate with another service, it queries the discovery service for the location of the target service.

Benefits

  • Scalability: Service Discovery makes it easier to scale services up or down without manually updating configuration files.
  • Resilience: If a service goes down, the discovery service can automatically remove it from the list of available services.
  • Simplicity: Service Discovery simplifies the process of managing service dependencies.
