I don't understand how anyone uses a paid API for a personal project. I looked hard into MS, Google and Amazon a few years ago for a project and couldn't find anywhere where you could hard block services to never ever go above the free tier.
Considering that I'll build a project and forget about it for years, putting in my credit card into a cloud service was a guaranteed gigantic bill sometime in the future when things went wrong. (Over your life, something is guaranteed to go wrong.)
Have you heard of virtual debit cards? You can't charge what's not there.
Also, at least AWS will in fact send you an email when you approach the end of free tour usage.
Having said all that, most devs can host the few hundred visits they might get over a month with a $200 home server and a free CloudFlare cache if they know what they're doing.
None of those specifically, but after you have a virtualization host your flock tends to grow pretty quickly. More that I'm hosting big multi-user things like nextcloud for a single user.
Learn to solve problems using programming. Go learn Python. Stick with the basics and have fun. If you start worrying about losing older versions of your code, learn Git. Grow from there.
Kubernetes? Microservices? Cloud platform? These are all distractions and a waste of your time.
I used to have this enormous dev folder of projects. Some with git, some before I knew what it was.
I clinged and backed it up like crazy, until I actually looked at what was contained (spoiler: horrid code). Then I just got used to burning some old code. Now I'm often distracted by stuff like docker, kubernetes and that stuff
It's fun though, I've grown a bunch. but the setup sometimes does overscale badly
I have a personal project that was getting big and unruly, and I'm so happy I learned how to use Docker and converted all the little pieces into their own repos and containers.
That being said, I totally went down rabbit holes that didn't end up being helpful, like setting up my own CI/CD or trying to learn Kubernetes. They were totally overkill for me.
