EDB Postgres Distributed Always On Architectures

This whitepaper describes the blueprint for Always On architectures for PostgreSQL. These architectures reflect EDB’s recommended practices and help customers achieve highest possible service availability in multiple different configurations, ranging from single-location architectures all the way to complex distributed systems that protect from hardware failures and data centre failures. The architectures leverage EDB Postgres Distributed's multi-master capability and leverage its ability to achieve 99.999% availability including maintenance operations.
