Consensus exists because coordination needs rules. The practical lesson is that agreement has a cost: latency, complexity, operational burden, and sometimes reduced availability.

Connected Knowledge

Concept

Distributed Systems

A distributed system is a system made of independent components that communicate over a network to behave like one useful whole.

Concept

Fault Tolerance

Fault tolerance is the engineering discipline of designing for partial failure instead of assuming perfect components.

Mental Model

Trade-offs

A way to reason about engineering choices where improving one property changes cost, complexity, risk, or behavior elsewhere.
