Qlik Sense Multi-Node Setup over cloud and on-premise nodes

[yura_ratu]

Hi All,

We are looking to the possibility to install Qlik Sense Server on multiple nodes - some of them on-premise, the other in the cloud (Azure). Haven't found the answer explicitly in the documentation available in the help section whether it's possible or not.

I've read about Qlik Sense Enterprise for elastic deployments, however, seems like for the moment it only allows users to open dashboards, they are not fully functional nodes.

Would appreciate any help here.

Yeah, you can install QSE on multiple servers which can be either on-prem and/or hosted by a cloud provider. The only thing you will need to do is make sure that the servers can talk to one another, which is less so a Qlik thing more so a SysAdmin responsibility. To the machines, it won't matter whether it is in the cloud or in your company's data center.

With that said, "elastic" is a whole other topic. If you want to dynamically scale, without the use of kubernetes, you will have to manage that all on your own. That means you will need to build the scripts to spin up a node in the cloud when usage hits a threshold. You'll need a way to spin down a node when usage is low, and unobtrusively move the users remaining (probably the hardest part) from the node about to be spin down. You'd also need to have an external load balancer which routes traffic accordingly. This is definitely not a small feat, but doable.
