High Availability

Large enterprise organizations typically require production systems to have some level of failover or high availability setup to achieve uptime targets. Snow Commander is an application that can be run in an Active-Passive clustered configuration to meet this common enterprise requirement.

This guide explains the process by which Commander is made highly available by using a two-node cluster of application servers. To further protect the availability, install the application against a highly available Microsoft SQL database. (Note that the default Postgres SQL database can't be used for a High Availability deployment.)

This guide uses as its example the Commander HA configuration with a front-end load balancer, but the same configuration will work for any service-aware load balancing solution.
