I never understood the popularity of AWS. It's much cheaper using VPSs and even dedicated servers sometimes. I've worked on very cost-sensitive projects where I rolled our own highly-available k8s and postgres clusters on dedicated servers and VPSs and saved the company a shit load of money. Only used the "cloud" to store backups (Backblaze). There's tons of other options other than major "cloud" providers, and they're often much cheaper.
