What is a key advantage of containerization over hypervisor-based virtualization?

Containerization offers a key advantage over hypervisor-based virtualization primarily through its lower resource consumption. Containers share the host system's operating system kernel, which allows them to start up quickly and use fewer resources than traditional virtual machines that require their own dedicated operating system instances. This shared environment leads to less overhead, resulting in more efficient use of system resources like CPU and memory.

Additionally, because containers are lightweight, they can be deployed and scaled much faster, allowing for agile development and operational environments. This efficiency is especially valuable in cloud environments and microservices architectures, where rapid scaling and resource management are crucial.

While the other choices touch on important aspects of technology, they do not directly reflect the primary advantage of containerization in the context of resource efficiency.
