Hello everyone! During one of those illuminated evenings, I got the idea to move my small server in Scaleway to some more powerful server in Hetzner. If I will make the move, I am thinking of splitting the server in various VMs, to host different services that belongs to different trust boundaries, for example:
- A Lemmy/writefreely instance
- Vaultwarden/Gitea
- Wireguard tunnel to my home infrastructure
- Blogs, and other convenience services
In order to achieve the best level of separation, I was thinking of using VMs. My default choice would be Proxmox, because I used it in the past, and because I generally trust it, however I am trying to evaluate multiple options, and maybe someone has good or better experiences to share.
Other options I thought about are:
- Run everything in Docker. I am going to do this nevertheless, but Docker escapes are always possible, especially with public facing images that I did not write myself and/or that require a host volume.
- KVM directly? I am OK even without a GUI to be honest. I am not aware if there is some ansible module or even better Terraform provider for this, it would be great. (EDIT: I found https://registry.terraform.io/providers/dmacvicar/libvirt/0.7.1 which seems awesome!)
- ESxi? I have no experience with this solution.
Any idea or recommendation?
For me, it’s a personal decision. I find BSD more cohesive. That is subjective and has been debated for a decade now. I also find
bhyvea bit easier to use, albiet the features are newer and more in number in KVM (for example:bhyveuntil very recently didn’t have VirtIO drivers, so Windows machines would be useless on it).I’m interested in working in Security myself. Would you be able to tell me a little more about your work? Also, what role/path in security would you recommend for a Cloud admin/System Admin?
Well, I started as an IT ops person, I got lucky before the first job was still in a fairly modern environment, and I got introduced to k8s, containers and linux administration (we were running k8s on baremetal). Slowly I moved more and more towards security, specifically infrastructure/platform security, which to be honest, is not too far from a regular Cloud/System admin. However, the big difference is in mindset and priorities, which slide from availability to mostly confidentiality and integrity. My job essentially consists on supporting the security of whatever Kubernetes cluster we run, both managed and on baremetal, with the usual spinkle of network security in the middle, and a strong focus in secure computation (i.e., container security). The actual work can range from research and experimentation, to concrete setup or development of new tooling, to developing standards and guidelines.
(Cloud) Security Engineering seems an obvious path for a cloud/system admin, and I don’t think it’s extremely hard to build the necessary security knowledge on top of a solid engineering background!
