EDB Postgres Distributed Always On Architectures

Database availability is more important than it has ever been. Your Tier 1 mission critical applications demand it, and so do your customers.

This white paper describes the blueprint for Always On architectures for PostgreSQL. EDB Postgres Distributed’s multi-master capability enables you to maintain extreme high availability, including rolling upgrades and providing up to five 9s uptime.

Achieve the 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 center failures.

This white paper covers:

• The structure of an Always On architecture
• How to choose the right architecture
• Deployment and sizing considerations
• How to add flexibility to your architecture
