2.5.2 High Availability or Multi-Tier Docker Installation

A High Availability (HA) architecture is one of the key requirements for any Enterprise Deployment. It refers to the ability of users to access a system without loss of service.

Deploying a High Availability system minimizes the time when the system is down or unavailable and maximizes the time when it is running or available. This section provides an overview of high availability from a problem-solution perspective.

High Availability (HA) preparation is an integral part of contingency planning. This section explains how a standard OFSAA deployment should be architected to protect its applications from unplanned downtime and minimize planneddowntime.
