This argument in favor of PaaS makes a lot of sense to me. A PaaS vendor might say, "sure, you could set up your own observability layer, configure storage for it, troubleshoot that one service that can't connect to the API's endpoint, etc. Or you could just check the "observability" box on our dashboard and boom, there it is."
I'm currently at a company that really likes setting everything up from scratch. And the amount of time my team has spent building out a platform, as opposed to providing business value, is really sobering.
And when you take a step back and think for a moment, it just doesn't make sense that you have to run a whole separate team for something that's pretty much reusable across products.
