## What it is
PGO is the Crunchy Data Postgres Operator, a Kubernetes operator that declaratively manages production PostgreSQL clusters. It automates high availability, disaster recovery, backups, monitoring, and rolling updates for Postgres on Kubernetes.

## Use cases
- run production postgres on kubernetes
- manage highly available postgresql clusters declaratively
- automate postgres backups and disaster recovery
- set up postgres database-as-a-service on k8s
- clone postgres clusters for staging environments
- roll out postgres upgrades with minimal downtime
- monitor postgresql clusters with metrics

## When to choose
- you run PostgreSQL on Kubernetes and want GitOps-style declarative cluster management
- you need built-in high availability, failover, and disaster recovery for Postgres
- you want automated backups, monitoring, and rolling updates without hand-rolled scripts
- you are building a database-as-a-service offering on Kubernetes

## When to avoid
- your databases run on VMs or bare metal outside Kubernetes
- you use a different database engine than PostgreSQL
- you need a fully managed hosted database rather than self-operated clusters
- you cannot adopt Kubernetes operators or CRDs in your environment

## Facets
- artifact type: service
