• An HP ML350p w/ 2x HT 8 core xeons (forget the model number) and 256GB DDR3 running Ubuntu and K3s as the primary application host
• A pair of Raspberry Pi’s (one 3, one 4) as anycast DNS resolvers
• A random minipc I got for free from work running VyOS as by border router
• A Brocade ICX 6610-48p as core switch

Hardware is total overkill. Software wise everything is running in containers, deployed into kubernetes using helmfile, Jenkins and gitea
