What is Kubernetes? Why organizations are using it?

Kubernetes, often abbreviated as K8s, is an open-source platform designed for automating the deployment, scaling, and management of containerized applications. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), Kubernetes has become the de facto standard for container orchestration due to its robust features and extensive ecosystem[4][6].

What is Kubernetes?

Kubernetes orchestrates containers across a cluster of machines, which can be either virtual or physical. It abstracts the underlying infrastructure, allowing developers to focus on application development rather than infrastructure management. Key components of Kubernetes include:

• Control Plane: Manages the overall state of the cluster, including scheduling, scaling, and maintaining the desired state of applications.
• Nodes: These are the worker machines where containers run. Each node contains the necessary services to run pods, which are the smallest deployable units in Kubernetes.
• Pods: A pod is a group of one or more containers with shared storage and network resources, and a specification for how to run the containers[4][9][17].

Why Organizations are Using Kubernetes

Organizations are increasingly adopting Kubernetes for several compelling reasons:

1. Scalability and Flexibility:

   • Kubernetes can automatically scale applications up or down based on demand, ensuring optimal resource utilization and cost efficiency[1][8][11].
   • It supports a wide range of workloads, from stateless applications to complex stateful applications and data-processing tasks[4][6].

2. Portability and Multi-Cloud Capability:

   • Kubernetes abstracts the underlying infrastructure, making it possible to run applications consistently across on-premises, public cloud, and hybrid environments. This reduces the risk of vendor lock-in and enhances flexibility[1][5][11].

3. Automation and Efficiency:

   • Kubernetes automates many operational tasks, such as deployment, scaling, and management of containerized applications. This reduces the manual effort required from DevOps teams and increases overall efficiency[1][2][9].

4. High Availability and Resilience:

   • Kubernetes ensures high availability by automatically restarting failed containers, rescheduling them on healthy nodes, and providing self-heal...
