Distributed Locking

Distributed locking is a technique used in systems where multiple computers or services need coordinated access to shared resources, like files or data. It ensures that only one system can access or modify the resource at a time, preventing conflicts and inconsistencies. Think of it as having a digital "lock" on a resource: before making changes, a system acquires the lock; after completing, it releases the lock for others. This process maintains data integrity and smooth operation across distributed systems, even when they are geographically separated or operating simultaneously.
