The best thing about nuWeBa is that it has everything in one place for you as an admin - so there's no need to have multiple tools at your disposal! It also gives us confidence when we're managing our cloud infrastructure because of its scalability (which allows us to grow with minimal downtime).
I would recommend using this service if you are looking into ServerLess architecture or want some peace of mind while monitoring Cloud Infrastructure. We use nubeaba primarily due to ease & speed of deployment but can't think of anything bad yet. Our main goal was having all applications under single umbrella allowing centralized management without any additional costs compared to traditional solutions like AWS ECS etc., Also being able to monitor both VMs running directly within Azure Stack vs those deployed via PKS/PKI stack.
