How to Install etcd on Ubuntu 24.04

etcd is a distributed key-value store used widely in modern infrastructure stacks like Kubernetes, service meshes, and microservice systems. It’s reliable, lightweight, and production-ready.This guide focuses on Install etcd on Ubuntu 24.04.

• Distributed Configuration & Coordination
  etcd provides strong consistency and distributed coordination using the Raft algorithm  making it ideal for shared configs.
  
• Service Discovery
  Applications can register themselves and discover each other via etcd.
  
• Critical Component in Kubernetes
  Kubernetes stores all its cluster data (pods, services, secrets, configs) in etcd.
