Which cloud use model allows you to use containers without having to manage the underlying hardware and virtualization layers, but still lets you access the underlying virtualization if needed?

Serverless computing (FaaS) completely abstracts the underlying infrastructure, meaning users only deploy code and have no access to the virtualization layers.

Containers as a Service (CaaS) provides a platform for deploying and running containers, abstracting away the management of the underlying hardware and virtualization layers, though some advanced configurations might allow limited access or insight into the underlying infrastructure.

Standard Docker containers refers to the container technology itself, not a specific cloud service model that abstracts infrastructure management.

VM-integrated containers imply running containers within virtual machines, which requires managing the VMs themselves, contradicting the requirement of not managing virtualization layers.
