🧿 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.

📖 Data Structure and Algorithm Patterns for LeetCode Interviews – Tutorial

This is a comprehensive course on data structures and algorithms. algo monster will break down the most essential data structures—like arrays, strings, sets, hashmaps, and heaps, and he'll show you exactly how and when to use them. You’ll also master core algorithmic patterns such as two pointers, sliding windows, binary search, breadth-first search (BFS), depth-first search (DFS), and backtracking, all explained with clear examples and real interview problems.
