In this artictle we are going to discuss about KUBERNETES
before learning about kubernetes we need to know about container and containerization and container Orchestration.

What is Container:-

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.

What is Containerization:-

Containerization is a method of packaging an application along with its dependencies, libraries, and configuration files into a single unit called a container. This ensures that the application runs consistently across different computing environments.

To know about container and containerization need to know about docker and its concepts
Docker fundamentals 🐳 and Advanced docker concepts

Container Orchestration:-

Container orchestration is the process of automating the deployment, management, scaling, and networking of containers throughout their lifecycle. This technology is essential for enterprises that need to deploy and manage hundreds or thousands of containers and hosts

What is kubernetes:-

Kubernetes, often abbreviated as K8s, is an open-source container orchestration platform that automates the management, scaling, and deployment of containerized applications. Developed originally by Google, Kubernetes is now maintained by the Cloud Native Computing Foundation (CNCF).

Pre-req to learn k8s:-

• Any cloud Knowledge (AWS,Azure,Gcp...etc)

• Docker Basics

• Docker fundamentals 🐳

• Advanced docker concepts

• Linux Basics

Why you need Kubernetes and what it can do

Containers are a good way to bundle and run your applications. In a production environment, you need to manage the containers that run the applications and ensure that there is no downtime. For example, if a container goes down, another container needs to start. Wouldn't it be easier if this behavior was handled by a system?

That's how Kubernetes comes to the rescue! Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application, provides deployment patterns, and more. For example: Kubernetes can easily manage a canary deployment for your system

Key Features of Kubernetes

1. Container Orchestration: Manages multiple containers across clusters of nodes, ensuring high availability.

2. Load Balancing: Distributes traffic across your application to ensure performance and reliability.

3. Scaling: Automatically scales applications up or down based on demand.

4. Self-Healing: Detects and replaces failed containers automatically.

5. Automated Rollouts and Rollbacks: Updates applications incrementally without downtime and reverts to previous versions if necessary.

6. Storage Management: Provides persistent storage for applications using various backends (e.g., cloud providers, on-prem).

Why Kubernetes is Powerful

It enables you to:

• Deploy applications consistently across different environments, such as on-premises, cloud, or hybrid setups.

• Optimize resource usage by efficiently scheduling containers on available nodes.

• Focus on development rather than infrastructure management.

Kubernetes is widely adopted because it supports flexibility, scalability, and resilience for modern cloud-native applications.

Conclusion

This article aimed to provide a high-level overview of Kubernetes, hopefully sparking your curiosity and encouraging you to delve deeper into its fascinating ecosystem. If you're intrigued, I urge you to explore Kubernetes further and immerse yourself in the rich world of cloud-native technologies.

Remember, Kubernetes may seem complex at first, but don't let it intimidate you. Once you've deployed a few applications, it becomes much more straightforward and intuitive to use—especially for developers. So, embrace the challenge and enjoy the journey!
