Many retail environments rely on high availability (HA) for uninterrupted functionality. Such operations may include theft detection and prevention, point of sale, inventory management, and real-time data analytics. The ability of these systems to maintain an agreed-upon level of uptime is critical for smooth operations. HA can also be configured based on role-based access requirements so that mission-critical users and devices achieve a higher level of availability compared to those with less importance. Similarly, HA systems should be configured so that the operations and workflows with lower importance (also known as noisy neighbors) do not interfere with mission-critical operations and workflows. Systems with proper high availability practices allow administrators to use the applications with minimal involvement, improving the productivity and reliability.
