Overview
A single PostgreSQL instance is a single point of failure. This engagement builds a PostgreSQL setup that survives a node failure without waking anyone up — streaming replication for redundancy, automatic failover so a downed primary doesn't mean downtime, and backups that are actually tested, not just scheduled.
What's Included
- Primary-replica streaming replication — synchronous or asynchronous, depending on your consistency requirements
- Patroni automatic failover — a downed primary is detected and replaced automatically, without manual intervention
- PgBouncer connection pooling — protect Postgres from connection exhaustion under load
- Automated backup with pgBackRest — scheduled, incremental backups with tested restore procedures
- Monitoring & alerting — replication lag, connection saturation, and failover events surfaced before they become incidents
Our Process
- Current state review — existing database setup, data volume, and RTO/RPO requirements.
- Architecture design — replication topology, failover strategy, and backup schedule proposal.
- Implementation — HA cluster built and validated with an actual failover drill, not just a config review.
- Handover — runbook covering normal operations, failover behavior, and how to restore from backup.
Who This Is For
Teams running a single PostgreSQL instance in production, or a "HA" setup that's never actually been tested with a real failover. Also relevant if you're currently paying for a managed HA database service and want to bring it in-house.
FAQ
Do you support managed Postgres (RDS, Cloud SQL) instead of self-hosted? Yes — for managed services, this becomes a configuration and read-replica strategy engagement rather than a Patroni deployment; the deliverable (tested HA, tested backups) is the same.
How do you test failover without risking real data? Failover is drilled against a staging or cloned environment first, then validated against production during a scheduled maintenance window.
What's the actual RTO/RPO we can expect? Depends on your replication mode — synchronous replication gets near-zero RPO at some latency cost; we'll size this to your actual requirements during the design phase.
