Containers are a form of virtualization at the operating system level. They are more lightweight than virtual machines because they share the host operating system’s kernel, making them faster and less resource-intensive. Containers allow multiple isolated applications to run on the same operating system instance. Virtual machines, on the other hand, virtualize the hardware and run their own guest operating system (OS) on top of a hypervisor. This makes VMs more resource-intensive, as each VM needs its own OS, which consumes more system resources compared to containers. Option B (VMs are faster): This is incorrect. Containers are generally faster than virtual machines because they do not require the overhead of running a full guest OS. Option C (Containers at hardware level): This is incorrect. Containers provide isolation at the OS level, not at the hardware level. VMs provide isolation at the hardware level by running a full OS on top of a hypervisor. Option D (Containers run multiple apps, VMs run one): This is not a correct distinction. Both containers and virtual machines can run multiple applications. The main difference is how resources are managed and isolated. Option E (VMs are part of serverless environments): This is incorrect. Virtual machines are not part of serverless environments. Serverless computing abstracts away infrastructure management, whereas VMs require managing the underlying infrastructure.
