Kubernetes Architecture
A Kubernetes architecture is a distributed, fault-tolerant computer system designed for managing containerized applications. Kubernetes provides a platform for developers and IT professionals to build, deploy, and manage containerized applications on multiple servers.
Pods
A pod is a group of one or more containers that are deployed and run together on the same physical server. Pods are managed by Kubernetes as a single logical unit, ensuring that they are deployed and scaled together.
Services
A service is a way to expose a pod's port externally. Services allow multiple pods to communicate with each other and access their services through a single IP address. Users can also access the service using a URL or by using a service mesh.
Example
Let's consider a cluster of three Kubernetes nodes (servers) running a web application. Each node contains two pods: a web server and a database server. The service is deployed to expose the web server's port 80 on the external IP address. Users can access the web application using the service's URL.
In this example, Kubernetes ensures that the pods are deployed on different nodes and that the service is accessible from the outside world. Pods and services are essential components of Kubernetes that allow developers and IT professionals to build and manage containerized applications efficiently
