Deploy PCS in HA mode without vTM

Deploy PCS in HA mode without vTM

Hello,

 

My PCS instance is hosted in AWS. Since I only have 1 instance running, the failure of this instance implies down time.

My goal is to achieve a redundant architecture to avoid that without introducing vTM in the architecture.

AWS best practices suggest creating multiple EC2 isntances and put them behind a load balancer.

However, I have 1 issue with this setup: the license. Since I have one license for PSA, another license for concurrent vpn users, if PCS #1 fails (where both previously mentioned licesnes are installed) and the traffic is sent to PCS #2, how are the licenses transfered to the other one? How do yo automate this? If this is impossible to implement, do you suggest other approaches?

 

Thanks in advance.

Regards,

Tony

Re: Deploy PCS in HA mode without vTM

To have an uninterrupted PCS deployment, you must have a High Availability Cluster on your deployment. We offer 2 options: Active/Passive and Active/Active deployments.

  1. Active/Passive Cluster: the active PCS accepts all the connection request. If the active PCS fails, then the passive PCS gets promoted and takes control of the incoming connection request. The active/passive utilizes a VIP and monitors PCS instances using heartbeats and health checks to check on the status of each server.
  2. Active/Active Cluster: this solution gives you the option to have two PCS servers to be actively accepting connection requests. The requirements for this topology will require a load balancer (Pulse Virtual Traffic Manager), platform license and concurrent licenses for both PCS servers.

For your request, you don’t need to have a new set of licenses if you use option 1: Active/Passive Cluster. In addition, one caveat is to have the same PCS appliance in a cluster. Also if it fails you have 20-day grace period to the licenses as long as your active/passive servers are in a cluster.
