Requirements (High Availability Deployment)

This section describes the CloudShell clustering requirements.

The following table lists the requirements for the following infrastructure components: NICs, Switches and host.

Based on the High Availability Deployment guide, the administrator should select the optimal set up for the environment (4/6 nodes on physical or virtual machines).

For additional requirements to configure Web Server Load Balancing, see Requirements (High Availability Load Balancer).

For hardware/OS requirements for CloudShell servers and clients, see Minimum Requirements for CloudShell Servers and Clients.
