People ask me fairly often what my home lab setup looks like and I have been putting off writing about it because it feels self-indulgent. But I get the question enough that it is clearly useful to some people so here is the honest version.
My philosophy on home labs is that the goal is hands-on repetition with the concepts you are testing on, not building the most impressive rack you can photograph for Reddit. Everything else follows from that. Spend what you need to get comfortable repetitions on the material. Do not spend more than that.
Right now I am running a small Proxmox cluster on two older workstations I picked up used. Total cost for both machines was under four hundred dollars. Proxmox is free and gives me a solid virtualization platform for spinning up VMs for whatever I am studying at the time. Right now those VMs are running Ubuntu servers that I am using to practice Kubernetes concepts for the CKA exam I am working toward. Before that it was Windows Server environments for Azure admin prep. The platform is flexible enough to serve multiple study goals over time which is important when you are on a budget and cannot dedicate hardware to a single use case.
For cloud-specific studying I lean heavily on free tier accounts. AWS Free Tier and Azure’s free credits give you enough access to do meaningful hands-on work with the services that appear most frequently on those certification exams. The important thing is to actually build things and break them, not just read about them. Reading documentation is necessary but it is not sufficient for the kind of recall and application that performance-heavy exams require.
For study materials I have been using a combination of official documentation, which for Kubernetes specifically is genuinely excellent at kubernetes.io, and practice exam platforms that let me identify weak areas before the actual test. I track wrong answers in a simple spreadsheet and come back to those topics until I stop getting them wrong. Not glamorous but effective.
The biggest upgrade I would make if I had more budget right now is more RAM. You can never have enough RAM for running multiple VMs simultaneously and it is consistently the bottleneck in home lab environments. If you are building from scratch and you have to choose between a faster processor and more RAM, take the RAM.
That is honestly most of what there is to say about it. It does not need to be complicated. It needs to run the things you are studying and be accessible enough that you actually use it regularly.
