5 Useful Free and Open Source Linux Service Discovery Tools

Service discovery is the process of automatically finding devices and services on a computer network. Service discovery uses a service’s identity instead of traditional access information (IP address and port). This allows you to dynamically map services and track any changes within a service catalog.

There are two main service‑discovery patterns: client-side discovery and server-side discovery.

Benefits of service discovery include:

  • Dynamic IP address and port discovery.
  • Simplified horizontal service scaling.
  • Abstracts discovery logic away from applications.
  • Reliable service communication ensured by health checks.
  • Load balances requests across healthy service instances.
  • Faster deployment times achieved by high-speed discovery.
  • Automated service registration and de-registration.

It aims to reduce the manual configuration effort required from users and administrators. A service discovery protocol (SDP) is a network protocol that helps accomplish service discovery.

In this roundup we pick useful service discovery tools. Only free and open source software is eligible for inclusion.
