I'm a junior DevOps engineer and I'm a bit worried about the direction I'm learning in, so I wanted to get some outside opinions.

At my job (and in my personal projects) I work almost entirely with on-prem / self-managed infrastructure. The stack I'm learning is roughly:

• K3s (self-managed Kubernetes on VMs)
• Cilium as the CNI (incl. Gateway API)
• ArgoCD for GitOps
• Ansible for provisioning
• Terraform
• Longhorn for storage, CloudNativePG for Postgres
• etc...

The thing is, I've never used a public cloud — no AWS, Azure, or GCP. No EKS/AKS/GKE, no managed databases, no Terraform against a cloud provider. Everything I do is bare VMs and self-hosted components.

My question: is this a problem? A few things I'm wondering:

1. Will I be at a disadvantage in the job market by not knowing the big clouds?
2. Are the concepts I'm learning (Kubernetes internals, networking, GitOps, storage, etc.) transferable to cloud-managed setups, or is it a different world?
3. Should I make an effort to learn a cloud on the side, or is deep on-prem experience valuable enough on its own?

I genuinely enjoy the on-prem / "build it yourself" side of things, I just don't want to accidentally box myself in. Any honest perspective from people who've been in the field longer would be really appreciated. Thanks
