Using Hetzner or IVH will cut your infra bill by 4x or 5x

This is true, but be careful about losing the work experience. Companies love cloud computing and somehow are conditioned to want to pay for them and anyone who works on them. I received a devops job application rejection because they didn't see cloud computing providers on my resume. That's because I highlighted running my own dedicated servers.

That’s because architecting stuff for the cloud effectively means you’re building your infrastructure differently to how you’d run dedicated servers. I say this as someone who’s done both professionally.

As a DevOps hiring manager, if you said to me “I don’t have cloud experience but I can do all the same things with dedicated servers” then I’d likely pass on you for another candidate too.

A better way to frame your applications is “I have significant on prem experience using DevOps methodologies, and I’m excited to broaden them with Cloud technologies.” That way you’re acknowledging your knowledge gap and turning it into a positive.
