Why Percona?

An architecture for every business need

Percona HA PostgreSQL architectures pull together open source tools and components to enhance and harden interoperability, ensuring your applications always have access to the data they need.
The HA infrastructure is built within a single data center on your local node. It is intended to keep the database available should the primary node go down, either from an automatic failover or planned switchover.
Availability is spread across data centers to add more layers of availability to the cluster. It is intended to keep your infrastructure available and data safe and consistent should a problem arise in the primary data center.

The infrastructure features a disaster recovery site and an external layer of ETCD nodes. Should communication between the sites be lost, the ETCD node layer will act as a “source of truth” and decide what replica will be promoted as a primary — keeping the cluster healthy without a split-brain and the infrastructure highly available.

The infrastructure features two disaster recovery sites, which ensures high availability and keeps your applications up and running. Based on tightly coupled database clusters spread across data centers and availability zones, it offers an HA level of 99.999% when using synchronous streaming replication, having the same hardware configuration in all nodes, and a fast internode connection.

Built solely with open source components
