High-Availability Database Cluster Deployment & HardeningRené Bon Ćirić
Eliminate database single points of failure, prevent costly application outages during hardware failures or maintenance windows, and ensure verifiable zero data loss.
We architect, deploy, and benchmark high-availability database clusters powered by PostgreSQL (with Patroni, pgBouncer, and WAL-G) or MariaDB Galera synchronous multi-master clusters on hardened CentOS Stream 10. Every deployment includes sub-second automated failover, connection pooling, continuous streaming backups, and verified point-in-time recovery (PITR).
Why Professional HA Database Clustering?
Zero-Downtime Maintenance: Perform operating system upgrades, security patches, and hardware replacements on individual nodes without taking your application offline.
Sub-Second Automated Failover: Distributed consensus agents detect node or network failures and promote healthy replicas instantaneously without manual intervention.
Connection Pooling & Query Routing: Decouple application connection spikes from backend database worker limits using high-performance connection pooling.
Verifiable Disaster Recovery: Continuous transaction log streaming to S3-compatible object storage with automated point-in-time recovery drills.
