Kubernetes introduces the concept of a pod for several reasons. Firstly, pods allow for better resource utilization and scheduling by allowing multiple containers to share the same resources. Secondly, it allows applications to be logically grouped together in terms of scheduling and deployment. Thirdly, they provide a mechanism to manage and organize related containers into groups. Finally, a pod provides an isolated environment with its own networking and storage resources, which can help secure the application and keep it isolated from other applications.
Containers alone are not sufficient for orchestrating complex applications or providing a stable platform for running them. Kubernetes solves this by providing a secure, scalable, and powerful container platform with the capability to deploy complete applications as collections of related containers. Pods form the fundamental building block of Kubernetes and are the basic unit of deployment when using the platform.
