No, the existing gear has stretch; innovation is software. My setup is one brain, a machine in the homelab that holds the platform, the customer projects, the photo library, the backups and the agents, reachable from anywhere. The cloud servers run the sites, the agents work from home. Everything else is glass: a screen and a keyboard to look at the brain with. A local model runs there with no data leaving the house. Two problems on the cloud were analysed and fixed on the same day in August, which is only possible when the agents can read the logs. So before you order a faster machine: give the one you have some agents and a look at its logs.
