Kubernetes, often abbreviated as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. It's essentially a platform that helps you run and manage applications across a cluster of machines, handling tasks like scheduling, networking, and storage orchestration

Key Concepts :

• Containers:Kubernetes works with containerized applications, meaning the application code, dependencies, and configurations are packaged together into a single unit
• Orchestration:Kubernetes automates the complex tasks of managing containers, such as deploying, scaling, and updating them
• Clusters:Kubernetes manages applications across a cluster of machines (nodes), providing a unified platform for your application
• Pods:The basic unit of deployment in Kubernetes is a pod, which can contain one or more containers that are tightly coupled and share resources.

How it works :

• Declarative Configuration: You define the desired state of your application using configuration files (YAML or JSON). Kubernetes then works to make the actual state match the desired state
• Automated Management:Kubernetes handles tasks like
• Scheduling: Deciding which nodes to run containers on.
• Scaling: Automatically increasing or decreasing the number of running containers based on demand.
• Service Discovery: Providing a consistent way for applications to find each other, even as containers are created and destroyed.
• Load Balancing: Distributing traffic across multiple containers.
• Self-Healing: Automatically restarting or rescheduling containers that fai

Benefits of using Kubernetes :

• Portability:Kubernetes can run on various infrastructure (public cloud, on-premises, hybrid)
• Extensibility:Kubernetes has a large ecosystem of tools and extensions that can be used to customize and extend its functionality
• Scalability:Kubernetes makes it easy to scale your applications up or down based on demand.
• Automation:Kubernetes automates many of the manual processes involved in managing containerized applications, freeing up developers to focus on other tasks.
• Cost Efficiency:By optimizing resource utilization, Kubernetes can help reduce infrastructure costs
