🧿 8 Most-Used Distributed System Design Patterns

If you are building a distributed system, you’ll need to use some of these patterns.

1 - Ambassador Pattern Focuses on offloading all major tasks other than business logic to helper services. Example of such tasks include logging, monitoring, and retries. 2 - Circuit Breaker Pattern This pattern helps prevent cascading failures when one service calls another service by preventing such calls. 3 - CQRS Pattern Separate read and write operations for better flexibility and supporting different scaling requirements. 4 - Sharding Split a monolithic database into multiple partitions known as shards for better horizontal scalability. 5 - Sidecar Pattern Deploy auxiliary components alongside the main service containers to manage cross-cutting concerns like configuration management, logging, and monitoring. 6 - Pub/Sub Used for asynchronous communication between publisher services and subscriber services. 7 - Leader Election In distributed systems, some tasks (such as leader-follower replication) need a single leader. Leader election algorithms ensure that only one node is designated as the leader. 8 - Event Sourcing Store the events or state changes in a separate event store. The event store can add the event to a message broker to update the read database.
