Hi Sebastian,
The configuration maximums are all listed here: https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-10A0804B-...
In addition, configuration maximums are part of the VMC Sizer, which can be found here: https://vmc.vmware.com/sizer/quick-sizing
I'd recommend you utilize the Sizer for your needs- it will ask for the number of total VMs, vCPUs/VM, vRAM/VM (simply round up to 1GiB), and Utilized Storage/VM.
