PostgreSQL High Availability and Scalability

PostgreSQL systems often need to stay online through failures while supporting more users, more connections, and heavier read workloads. In this course, PostgreSQL High Availability and Scalability, you'll gain the ability to design and operate practical PostgreSQL availability and scaling patterns. First, you'll explore building physical streaming replication and inspecting the WAL, lag, and slot behavior behind it. Next, you'll discover how to compare asynchronous, synchronous, and quorum synchronous replication while practicing promotion and failover mechanics. Finally, you'll learn how to add PgBouncer, route read traffic to replicas, use logical replication for selective scale-out, and evaluate monitoring signals that help you choose the right architecture. When you're finished with this course, you'll have the skills and knowledge to plan and validate PostgreSQL HA and scalability approaches needed to align with real operational environments.
