Virtualisation

Shipping Virtual Machines and Containers

Creating and managing virtual environments. Exploring containers with docker and kubernetes. Deploy opensource hypervisors solutions like Proxmox, OpenStack and Incus. Going hands on with virtual machine setup, resource allocation, and machine containers with lxc and LXD. How I maximize hardware utilisation and build services for fun and profit and flexible test environments in my lab.
