Contrast:

"Meanwhile, we suggest using the stronger security and isolation properties of EC2 instances to separate any untrusted workloads."

with:

"Google Compute Engine employs host isolation features which ensure that an individual core is never concurrently shared between distinct virtual machines. This isolation also ensures that, in the case that different virtual machines are scheduled sequentially, the L1 data cache is completely flushed to ensure that no vulnerable state remains."

The former does not inspire confidence. Given the hypervisor on EC2 is opaque to me, I'm not sure how I'm supposed to avoid co-tenanting in a risky fashion.
