When I first started building out my Proxmox environment, creating a full virtual machine for every service felt like the safe choice. Each application got its own operating system, virtual disk, memory allocation, and clearly defined place on the server. It looked organized and, more importantly, felt properly isolated. After a while, though, I had several nearly identical Linux installations running just to support small services that barely used the resources I’d a**igned them. Moving most of those workloads into Linux containers, or LXCs, made the waste much harder to ignore, because the same hardware suddenly felt quicker, less crowded, and much easier to maintain.
