For a little context, this is a dev ops group but entirely flexible.

I've run lab sessions (that were attended pretty okay) where AWS gave us a bunch of credits for people to hack on lambda to explore different languages for Hacktober.

I had another where we managed to get a senior engineer from Pulumi, Hashicorp (for Terraform), and AWS (to present CDK) and got them to give a highlight and demo as to why pick them which I thought would be fun, and I found really interesting. For the heavy tech city that I'm in, it wasn't well attended.

Has anyone have thoughts as to what they would be interested in learning more about, more hands on?

As I said, I'm planning on folding because of the lack of feedback so this is more curiosity.
