a8s PostgreSQL: Postgres
operator for Kubernetes

Run production-grade PostgreSQL in Kubernetes without all the manual ops or ticket queues.

Purpose-built Postgres for Kubernetes

a8s PostgreSQL brings a developer-friendly, operations-safe PostgreSQL experience to Kubernetes. Unlike traditional DBaaS products that rely on VM-based infrastructure, a8s PostgreSQL runs natively in Kubernetes pods. This means no context switching, no external dependencies, and no compromise on control.

Built with declarative APIs, GitOps compatibility, and platform automation in mind, a8s PostgreSQL is ideal for teams that want to treat data infrastructure like application infrastructure: versioned, repeatable, and observable.

Benefits of a8s PostgreSQL

Declarative & GitOps-friendly

Manage database instances like any other Kubernetes object. All changes can be version controlled, peer-reviewed, and rolled back.

Developer self-service

Empower your developers to provision, bind, and scale PostgreSQL instances on demand—without waiting on platform teams.

Keep data local & secure

Run fully managed PostgreSQL inside your own Kubernetes clusters—no vendor lock-in or forced multi-cloud exposure.

Operational automation

a8s PostgreSQL handles backups, failover, replication, and observability out of the box—freeing operators to focus on higher-order work.

Efficient resource usage

Share infrastructure between apps and databases to reduce cloud spend and simplify your environment.

Integrates with your platform stack

Designed to work with popular Kubernetes tools to easily plug into your existing CI/CD, monitoring, and GitOps workflows.

DBaaS features at a glance

Automated backup & restore

Secure, encrypted, and compressed backups with seamless recovery via the Kubernetes API.

Kubernetes-native bindings

Easily bind applications to database instances using standard Kubernetes patterns.

High availability & replication

Built-in failover and replica orchestration with topology awareness for rack/zone resilience.

Prometheus-compatible metrics

Instant visibility into health, usage, and potential issues that integrates cleanly with existing monitoring stacks.

Other database & data-related services

Looking for more than PostgreSQL? Explore our a9s Data Services for enterprise-grade databases like MongoDB or other data services such as Valkey for caching, RabbitMQ for messaging, and more. They are ideal for organizations running VMs or using Cloud Foundry.

If you’re managing both VMs and Kubernetes, check out our open-source project Klutch to manage VM-based data services as if they were local to Kubernetes. a8s PostgreSQL plugs right in for a unified control plane for hybrid environments.
