Your app goes down. Your database has no failover. Now what?
One region failing is all it takes to find out your database isn't actually replicated — it was just on your list. ZeusK8s makes multi-region replication a deploy-time decision, not a recovery-mode crisis, for the database you already run.
Your database. In two regions. Without touching your app.
There's a well-trodden answer to "my database needs to be global": rewrite your application against a distributed database. That's a project measured in quarters, and most teams have an app that works and a deadline that doesn't move.
ZeusK8s takes the other road. Deploy MySQL, PostgreSQL, or ClickHouse and tell it to go global. We stand it up across your clusters, wire the replication, and hand your application a normal endpoint. No new driver. No new query dialect. No migration weekend.
Need strict synchronous global writes? Zeus also runs Yugabyte — same deploy flow, same operational surface, full multi-master consistency.
Replication was supposed to be a follow-up ticket. It never happens.
No more "we'll set up replication later"
Cross-region replication is configured when the database is created, not a follow-up ticket that ships to the bottom of the backlog. Primary and replicas are placed across your clusters with locality in mind.
Backups & point-in-time restore
Scheduled backups to S3-compatible storage, and the ability to roll back to a moment or stand up a brand-new cluster from a backup.
Failover you can reason about
One board for topology, lag, and actions. MySQL multi-cluster auto-arbiter when eligible; guided switchover and rebuild for every engine. You always see which path applies.
PostgreSQL
CNPG-based PostgreSQL with HA failover, continuous WAL archiving, and point-in-time restore — same deploy flow, same global replication model as MySQL.
ClickHouse
Columnar analytics with multi-region replication and the same ops surface — topology, lag, rebuild guidance, backups.
Yugabyte
Synchronous multi-master writes across regions. Deploy it the same way as any other database and get strict global consistency — plus the same cross-cluster networking, DNS, and operations on top.
Standard data, no lock-in
Real databases with real replication protocols. Export, dump, point your own tools at it, or leave. The data was never hostage.
RDS is a great database. It's also an anchor.
The managed databases from AWS and Google are excellent — right up until your infrastructure needs to span both. Their replication ends at their own cloud's edge, so every service that touches the database is anchored to one provider, and "we could move if we had to" quietly stops being true.
The alternative — running your own databases — usually means someone becomes the DBA on top of their actual job, or you buy a separate management product to do the monitoring, backups, and failover for one engine.
Zeus closes that gap: real open-source engines running in your clusters on any cloud or Proxmox/k3s, with monitoring, health checks, backups, and failover controls handled as one product surface — the managed-database experience, without the single-cloud anchor.
Async or synchronous. Zeus runs both.
- · No rewrite. Your existing app keeps talking to the same endpoint.
- · Write in one region, reads from the nearest replica when configured.
- · Shared monitoring, backups, and failover controls — recovery physics match each engine.
- · Right for: existing apps, tight deadlines, multi-region without a migration weekend.
- · Strict multi-master consistency across regions.
- · A write commits in two regions or it doesn't commit at all.
- · Right for: financial systems, inventory, anything where split-brain is not acceptable.
Both models deploy the same way inside Zeus. Both get cross-cluster networking, DNS, IAM, observability, backups, and operations. The difference is the consistency model — and how each engine recovers, which Zeus surfaces honestly.
