Which cloud use model runs just one container per virtual machine?

1. Serverless

2. Containers as a Service (CaaS)

3. Standard docker containers

4. VM-integrated containers

The correct answer is: VM-integrated containers

The correct choice highlights the concept of VM-integrated containers, which operate by deploying a single container within a dedicated virtual machine (VM). This model effectively combines the virtualization benefits of traditional VMs with the lightweight capabilities of containers. By running one container per VM, it enforces a level of isolation and security since each container is fully encapsulated within its own VM environment. VM-integrated containers allow users to utilize the full functionality of a VM, such as managing networking and storage resources, while still benefiting from the efficiency and speed of containers. This architecture is well-suited for scenarios that require the rigorous security and configuration offered by VMs, alongside the agility and quick application deployment intrinsic to containers. On the other hand, serverless architecture is designed for executing code without the need for managing servers, and it typically abstracts away both containers and VMs. Containers as a Service (CaaS) provides a platform for deploying and managing containers, often enabling multiple containers to run on a single VM. Standard Docker containers do not inherently mandate a one-container-per-VM model, as they can run multiple instances on a single VM, which offers flexibility but contrasts with the specific setup of running one container per virtual machine.
