I think it will be abstracted kubernetes - something a little like ec2, but where the cpu, memory, and disk are multi-tenant, overprovisioned, and your code and aps run on the os provided, but are suspended during non use and unsuspended by the supervisor service on demand. Common architectures are available (elk, ssh/scp, tls load balancer with lamp/tomcat-postgres/etc.) Out of the box with automating, overprovisioned, multi tenant bandwidth, storage, etc.

Virtual private servers, but suspended/resumed/scaled for you without you needing to worry about the underlying method of deployment. AWS lambda + aurora but running actual operating systems. You want more threads or memory - they're there for you. Every user process is metered and monitored. Charged by cpuops + memoryops + iops + hdstorage bytes by the second. You never need to worry about how much disk you need, it's there, unlimited except by your pocket book. You never need to worry about how much compute you need - it's there, unlimited by your pocketbook. You never need to worry about how much memory you need. Backups of your drives are automatic.

All data is encrypted to allow it to live amongst all the other tenants' data. All wire traffic is encrypted.

It works exactly like ec2, except it's on-demand usage and overprovisioned and multi-tenant. Alarms and user-set limits for price and scale are respected. The only thing that will leak about the abstraction is that you'll have to mark processes as suspendable and dependent. You don't need to run your metrics collector if your app isn't running. Cron jobs should wake up the server, etc. Ssh/scp just works. You get service discovery out of the box, and your point of entry is the app lb dashboard. A real, on-demand, virtual private cloud.
