In information technology, high-availability application architecture is a process followed when implementing a new application into an existing business-wide computer system or ERP while minimizing downtime. The architecture contains three stages: development, quality assurance, and production. High Availability is usually achieved through redundant set-up of each component such that any single point of failure is avoided.
In computer networking, the Hot Standby Router Protocol is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway.
