The Eight Fallacies of Distributed Computing
Explore the classic assumptions developers make about networked systems that lead to failures. Learn how to avoid these pitfalls in distributed architecture.
The FLP Impossibility Result
The FLP impossibility theorem proves that no consensus algorithm can guarantee termination in an asynchronous system with even one faulty process. Understanding FLP is essential for distributed systems designers.
Google Chubby: The Lock Service That Inspired ZooKeeper
Explore Google Chubby's architecture, lock-based coordination, Paxos integration, cell hierarchy, and its influence on distributed systems design.
Google Spanner: Globally Distributed SQL at Scale
Google Spanner architecture combining relational model with horizontal scalability, TrueTime API for global consistency, and F1 database implementation.
Gossip Protocol: Scalable State Propagation
Learn how gossip protocols enable scalable state sharing in distributed systems. Covers epidemic broadcast, anti-entropy, SWIM failure detection, and real-world applications like Cassandra and Consul.
Graceful Degradation: Systems That Bend Instead Break
Design systems that maintain core functionality when components fail through fallback strategies, degradation modes, and progressive service levels.
Health Checks in Distributed Systems: Beyond Liveness
Explore advanced health check patterns for distributed systems including deep checks, aggregation, distributed health tracking, and health protocols.
Leader Election in Distributed Systems
Leader election is the process of designating a single node as the coordinator among a set of distributed nodes, critical for consensus protocols.
Logical Clocks: Lamport Timestamps and Event Ordering
Understand Lamport timestamps and logical clocks for ordering distributed events without synchronized physical clocks. Learn how to determine what happened before what.
