Do you need a “cloud”, as in a programmatic API to access and provision a pile of compute and storage? Or do you mean a “cloud” as in a bunch of locally hosted productivity tools?
The first case, creating a pool of resources with API access to deploy VMs, can be accomplished with something like CloudStack or OpenStack. This is what you would want if you are just handing off compute and storage resources for other teams to provision and deploy software on.
If you are managing internal IT resources and software, especially critical infrastructure like DNS, NTP, virtual routers/firewalls, identity management platforms, then you probably want a a hypervisor solution like Proxmox, or Nutanix or VMware if you have need of the extra features and have the budget for it.
My base infrastructure and productivity suite looks like this:
- Proxmox + Ceph for hypervisor and storage
- Red Hat IdM for directory services and PKI
- Chrony for NTP and Bind for internal/external resolvers
- Grafana / Prometheus / Loki for metrics and log ingestion, alerting, and dashboards
- Ansible for configuration management
- Caddy for edge proxies
- OPNsense for virtual routers
- Gitlab for source control and issue tracking, and I abuse scheduled CI/CD a bit as a distributed scheduler
- Keycloak for SSO auth to hosted apps
- Outline for wiki
- Grist for hybrid spreadsheet / database
- OwnCloud Infinite Scale for document management, integrated with OnlyOffice and Draw.io
- JetBrains YouTrack for project management
- Sharry for large file sharing externally
There is a lot of addressable market that can add chargers inexpensively. But I get that doesn’t mean much to anyone in a 70 year old home with a full panel, all electric appliances, and 2 AWG cable buried in the yard.
To try to save some money, make sure you really need the 40 amp charger circuit and make sure your panel really needs the upgrade. I don’t want to imply that you are getting into $6k of work without thinking very hard, but here’s some thoughts and observations, just in case your electrician didn’t suggest all this.
Tandem breakers can be used to move two single-pole circuits into one breaker slot. Doing this with four circuits can free up space for a double. Also check on how much peak load you are actually pulling, then figure on how many reactive starting loads are realistically going to happen at once (like AC coming on). I have the 40 amp charger circuit, a 50 amp hot tub circuit, a dozen servers pulling ~7 amps all day, and two air conditioners (main 40 amp and garage mini-split 15 amp). My peak 1 minute load is like 59 amps while charging the car. All that said, if you have electric baseboard heat in your home that can be a lot tighter of a squeeze.
I have had the EV for two years and I also find that a 240v 15 amp charger circuit, 12 amp max charge would have been perfectly fine for me. That would allow recovery of about 60 miles overnight, or ~90 miles in a typical commute-to-commute time-span of 14 hours. That’s with a big chonky Nissan Ariya, the Bolt will do better.
