Each pod gets a dedicated IP address thatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s shared by all the containers belonging to it. They are co-located on the same host and share the same resources, such as network, memory and storage of the node. The concept of a pod in Kubernetes makes it easy to tag multiple containers that are treated as a single unit of deployment. If Kubernetes is the new operating system, then a pod is the new process.

This design calls for pairing the web and cache container together and co-locating them within the same host. When the request comes to a web container, it checks for the data set within the corresponding cache container if it is not found, a database query is made to MySQL. When the web tier is scaled out by running additional containers, the cache container also needs to be scaled out. For example, the cache container should be kept close to the web container. This pattern makes deployment challenging. If you throw Memcached or Redis into the stack for caching, they need to run on a separate container as well.

Based on my personal experience, I am attempting to call out the features that make Kubernetes the standard for container orchestration.
