The system to be used as Cloud in a Box must fulfill these minimum requirements.

| Type of resource | Amount | Note |
|------------------|---------------------------------------------------------|-------------------------------------------------------------------------|
| CPU | at least 1 socket with 4 cores | |
| RAM | at least 32 GByte | |
| Storage | at least 1 TByte | Has to be available as `/dev/sda` or `/dev/nvme0n1` |
| Network | at least 1 network interface (dhcp and internet access) | An optional 2nd network interface can be used for external connectivity |
| USB stick | at least 2 GByte | Installation media for cloud in a box bootstrapping |

| CPU | at least 1 socket with 4 cores | More is better here. This is the minimum where you can't use much payload (LBaaS, VMs). The use of Kubernetes with Cluster API is not possible with this minimum size. |
| RAM | at least 32 GByte | More is better here. In principle, it also works with 8 GByte, but then no payload (LBaaS, VMs) can be used. Kubernetes with Cluster API cannot be used then. |
| Storage | at least 1 TByte | Has to be available as `/dev/sda` or `/dev/nvme0n1`. Less than 1 TByte is also possible, the smaller the less storage is available for use in Ceph. |
| Network | at least 1 network interface (DHCP and internet access) | An optional [2nd network interface can be used for external connectivity](#use-of-2nd-nic-for-external-network). |
| USB stick | at least 2 GByte | Installation media for Cloud in a Box bootstrapping |
