Do people here think the ideal public cloud infrastructure would be a cluster in a box rather than a single symmetric multiprocessor running virtual machines from multiple users? For example, imagine a 1U chassis containing 12 processor chips and 12 hot-swap 2.5” U.2 NVMe drives. Each processor chip could include:

8 performance CPU cores plus caches
interfaces to two 128-bit LPDDR DRAMs
4 PCIe lanes to connect to one NVMe drive
a 10G ethernet connection

If the minimum unit a cloud user could get is 8 cores, they would not be sharing this chip with anyone else so the risk of data leakage between users would be greatly reduced. If it is possible to combine these processor units for bigger single tasks but still keep them partitionable into independent units for small tasks, that would be even better.
