Architecting a high availability system
The Pega Platform supports production service level agreements and emphasizes redundancy as a best practice for physical and software-based highly available production architectures.
In the following diagram, redundancy is applied to the infrastructure across all tiers of the hardware and deployment architecture of Pega Platform servers, represented by the shadowed icons. For example, one implementation can have several load balancers, physical and virtual machines, shared storage repositories, and databases. These principles are general to three-tier architectures and are applicable to private hosting or cloud environments.
