Multi-Node setup and Session persistence

nfederico360insights — Wed, 29 Jan 2025 16:57:53 GMT

My team is working on deploying Qlik on an AWS multi-node solution, for which we require that proxies V1 and V2 Protocols as well as a "True Source ID".

Now we have a challenge with the management of the (ticket) sessions across the nodes:

Can Qlik’s Load Balancer manage sessions across the multinode solutions without an external (AWS) Load Balancer?

What are the pros/cons of enabling or disabling the AWS Load Balancer?

Would it be advisable to move to a authentication method that doesn't use Certs?
What is the best solution given the above details?

Thank you,
Nico

Hi @nfederico360insights

Yes, Qlik Sense can manage sessions natively via its QPS (Qlik Proxy Service).

Adding a Network Load Balancer ( ALB in your case) is generally recommended to allow your environment to be highly available (HA).

Typically a NLB would redirect sessions to at least 2 QPS, so if one QPS is down it should still send users to other QPS.
