Question
What is the primary advantage of using container
orchestration tools like Kubernetes over traditional virtual machines (VMs) for managing applications in a production environment?ÂSolution
Containers are designed to encapsulate only the application and its dependencies, without the need for an entire operating system like in virtual machines. This lightweight nature makes them portable across environments, faster to deploy, and much more efficient in using system resources. Container orchestration tools like Kubernetes manage these containers at scale, automating deployment, scaling, and management, which provides an edge in modern production environments. Why other options are wrong: A) Containers are lighter than VMs, so they actually require fewer resources. B) Containers share the host OS kernel, making them more efficient but not necessarily more secure than VMs, which run isolated OS environments. C) Containers do not run multiple OSes simultaneously; they share the host OS. E) Containers have faster startup times due to their lightweight nature.
