In the 90's, everything was on-prem.

It was in your control, but expensive, hard to update, over-provisioned.

Lots of capex.

Then we moved everything to the cloud.

Predictable expense for just what you actually used, easy to update.

A shift to opex.

But with a downside: now out of your control!

The host could theoretically peek inside your VMs:

Perhaps from misconfiguration

Or a wayward SRE

Or a subpoena from law enforcement.

But now with confidential compute and Private Cloud Enclaves, we get the benefits of the cloud, but also under your control.

The best of both worlds!
