So I'm creating a lock on the database because requests can be multi-threaded. And the VMs is just basically an ID to a virtual machine. All right. So I'm creating my application and now the data model. So the image is an enum with Ubuntu, Debian, and Alpine. And the VM has a CPU count, memory size, and the image which is one of these.
