Overview

CloudShell High Availability is available for Premium accounts only.

This document presents the recommended architecture for implementing CloudShell in a High Availability (HA) environment and should be read in conjunction with the CloudShell HA Installation and Configuration Guide.

A failover cluster is a group of independent servers (nodes) that work together to increase the availability and scalability of clustered nodes. The clustered nodes are connected by physical cables and by software. If a disaster occurs and the active cluster node goes down, the clustering solution changes the active node automatically to the standby server and Quali server starts on the new active node.

Use Cases

This document covers the following use cases:

• Planned downtime: scheduled by administrator. Used for maintenance purpose. The primary system is manually switched to the standby mode.
• Unplanned downtime: failure of one of the component in the system, automated failover.
