Identity at Scale; How Okta uses Postgres
summary
Operating a fleet of 650+ Postgres clusters across two clouds, Okta runs Postgres alongside Redis, DynamoDB and MongoDB and relies on Kubernetes and DBaaS for automation; backups, PITR, version upgrades and observability are operational pain points. Scaling prefers vertical scaling for fast emergency capacity, uses manual logical splits for horizontal scale, and groups databases by retention and criticality into tiered shared vs dedicated clusters. Deployments use red-black flips and PG Bouncer to absorb connection storms; move triggers and heavy audits out of the DB or offload to replicas.
