The described technology is containerization. Containers are a form of OS-level virtualization where applications run in isolated user spaces but share the host operating system's kernel and resources. This architecture allows for extremely rapid startup and deployment compared to traditional virtual machines, which must boot a full guest OS. However, because the kernel is shared, the isolation between containers and the host is less complete than the hardware-level isolation provided by hypervisors for VMs.

A. Type 1 hypervisor: Runs on bare-metal hardware and hosts entire virtual machines, each with its own OS, providing strong isolation, not sharing the host OS kernel.

C. Virtual desktop: This is a use case for virtualization (VDI), not the underlying technology itself. It can be implemented using VMs or other technologies.

D. Virtual machine: A VM emulates a full computer system, including its own guest OS and kernel, resulting in slower startup and strong, not limited, isolation.
