Configuring High Availability for Cloud Licensing

Sentinel LDK supports configuring a vendor-hosted cloud license server for high availability.

Sentinel LDK License Manager servers in the vendor's data center can be configured to store licenses in a common external trusted license storage (a MySQL database cluster).

NOTE Sentinel LDK License Manager servers are referred to as license servers in this document.

You can set up two or more active license servers. The load balancer spreads out the traffic of the workload among the license server machines. All of the License Managers handle license requests simultaneously.

This section describes how to configure Sentinel LDK to support high availability for cloud licensing hosted by the vendor.

NOTE

>The purpose of this section is to demonstrate one method for implementing high availability, using NGINX. Using the functionality provided by Sentinel LDK, you can use the same tools and methods or you can use other tools and methods to accomplish the same goal.

>If you are working with the active-passive configuration for multiple License Managers, see the High Availability Configuration Guide available from here.
