Distributed Locks

Coordination Services in Distributed Systems (ZooKeeper, etcd, Consul)

April 9, 2026March 16, 2026 by Rahul Suryawanshi

Coordination services provide strong consistency and fault tolerance for leader election, locks, and configuration in distributed systems.

Coordination and Distributed Locks in Distributed Systems

April 9, 2026March 16, 2026 by Rahul Suryawanshi

Coordination allows distributed systems to serialize access, elect leaders, and maintain correctness despite failures and unreliable time.
