DATABASE RELIABILITY / REGION EU-CENTRAL

Keep the write path boringly reliable.

Managed PostgreSQL-style infrastructure for teams that care about replication lag, predictable failover and knowing exactly where their data is.

01 / CLUSTER MAP

One write leader.
Three ways to stay calm.

Replication is visible, boring and deliberate. Every node exposes role, lag and health without hiding behind a generic green checkmark.

02 / RELIABILITY PRIMITIVES

Everything around the database matters too.

01

Continuous WAL archive

Point-in-time recovery with immutable retention and routine restore verification.

VERIFIED
02

Connection pool guardrails

Protect the primary from stampedes with pool saturation controls and bounded queues.

62%
03

Replica-aware routing

Send analytics and read-heavy traffic away from the write path automatically.

ACTIVE
04

Failure drills

Practice promotion, client reconnection and rollback before the real incident.

MONTHLY

03 / OPERATIONS

Watch the state change, not just the dashboard.

Use the simulation to promote the synchronous replica, re-point traffic and watch the cluster settle. No backend is involved — it is a local UI demo running entirely in your browser.
