SV and financial services are quite different.

It's 2026 and banks are still running their mainframe, running windows VMs on VMware and building their enterprise software with Java.

The big boys still have their own datacenters they own.

Sure, they try dabbling with cloud services, and maybe they've pushed their edge out there, and some minor services they can afford to experiment with.

If you are working at a bank you are most likely not standing up your own Postgres and related services. Even 15 years ago. I am not saying it never happened, I am saying that even 15 years ago even large orgs with data enters often had in place sys and devops that helped with providing resources. Obviously not the rule but also not an exception.

True. We had separate teams for Oracle and MSSQL management. We had 3 teams each for Windows, "midrange" (Unix) and mainframe server management. That doesn't include IAM.
