I remember discovering Heroku while I was in grad school in 2014. I was learning how to use AWS...which in a way was a lot simpler back then. But I was working on different kinds of workloads and more focused on learning Hadoop so it didn't seem that useful to me and I kind of, disdained things that were "too simple." Seeing it again several years later it seemed a lot more useful to deploy webapps for dev projects but there didn't seem to be a way for us to leverage in in prod. Needed much more control and capability to run complex apps. Like, I was setting up ELK stack and I couldn't see how to integrate so I just...stopped thinking about Heroku, lol.
