Covers master-replica, multi-master, and leaderless replication topologies and their tradeoffs.

Covers horizontal and vertical partitioning and consistent hashing for distributing data across nodes.

Covers the saga and outbox patterns and eventual consistency as alternatives to distributed ACID transactions.

Covers the CAP theorem's consistency, availability, and partition tolerance tradeoff.

Extends CAP with PACELC's latency-vs-consistency tradeoff and its practical implications for system design.

Horizontal vs. vertical scaling, autoscaling, and load shedding as the toolkit for absorbing load spikes without over-provisioning permanently.

Multi-region active-active vs. active-passive topologies, and the consistency and failover trade-offs each one makes.

Capacity planning, FinOps, and resource optimization as the discipline that keeps reliability decisions honest about what they cost.
