For most personal projects, hosting on the cloud may be overkill, but tempting with its supposed ease of use and benefits of scale. Self-hosting is often overlooked as a solution with the benefit of simplicity and cost.
Interesting discussion and demonstration of self hosting the kinds of apps most personal projects will end being.
I think this is an excellent video and I love the format of walking through a complete on-prem deployment.
My only criticism is the attack on “the cloud” as a whole. You can choose your level of abstraction, from a computer in the cloud (like EC2) to managed services (like EB). Personally I don’t want to deal with hardware, so I use a Compute instance on Oracle cloud (free tier). The rest of my setup is similar to the author’s.
