I noticed that on virtually any platform that provides managed databases (Digital Ocean, GCP, AWS, etc etc) has non-linear price increases. I use a managed db service personally and it's easily 90% of my infrastructure bill. Why is that? What's going on under the hood? Is it really that costly for a service provider to provide a reliable and safe db?
Edit; I was referencing specifically postgresql, mongodb, and mysql
You can often configure these a bit, things like number of open connections allowed.
Is it expensive? Is managing it yourself actually cheaper? How do salaries effect this calculation?
Think about configuring a multi az sync replication dB yourself. Then back it up regularly. Then make it scaleable. Patch management. It pays for itself!
which database? is it a licensing thing?
I've mostly noticed this with postgresql
