2. This sounds great. I like the k8s angle particularly as well - I have yet to find much useful in that area, so having a service that's good at it would be wonderful.
3. This I'd imagine would be end-game at AWS. Specifically ability to handle own storage and keys would be an immediate sell here. We've just taken on Slack Enterprise Grid for basically this (granted this was a 2-way deal: https://www.theverge.com/2020/6/4/21280829/slack-amazon-aws-...) so clearly we're up for it :D
I get the focus though. Seems like a good opportunity to set yourself up as best-in-class for this type of thing. I'll certainly be using CloudSkew for anything I need privately. :)
