Kubernetes

About container

A container is a lightweight and portable software package that contains everything needed to run an application, including the code, runtime, system tools, libraries, and settings
Containers decouple the application from the underlying infrastructure allowing us focusing on application development rather than underlying infrastructure.
Containerization of application fits well into DevOps practice by simplifying CI/CD processes

Why To Use Container?

Simplifies and accelerates application development workflows
Container allows applications to be shuttled easily between environments by encapsulating everything an application needs to run
Gives developers the freedom to innovate with their choice of tools, application stacks, and deployment environments
Reduces complexity (multiple languages, frameworks, architectures etc.) of software development lifecycle
Containers much smaller, faster, and more efficient than Virtual Machines
Takes away repetitive tasks and makes application development lifecycle fast, easy and portable
Build once, share and run anywhere, any counts of instances
Solves “… but it works in my machine” problem
Containers provide several benefits, including: Portability, Scalability, Isolation Efficiency

Kubernetes is an open-source container orchestration platform
Kubernetes provides a framework for automating the deployment, scaling, and management of containerized applications
Kubernetes abstracts away complex container management tasks
Kubernetes also called K8s

Why To Use Kubernetes?

Scalability: Kubernetes allows easy scaling of applications to handle varying levels of demand.
High availability: Kubernetes ensures application availability by automatically recovering from failures and distributing traffic effectively.
Container orchestration: Kubernetes simplifies the management of containerized applications, automating deployment and updates.
Resource efficiency: Kubernetes optimizes resource utilization, preventing resource wastage and maximizing cost-effectiveness.
Portability: Kubernetes provides a consistent platform for deploying applications across different environments, avoiding vendor lock-in.
Self-healing: Kubernetes monitors application health and takes corrective actions, ensuring high availability without manual intervention.
Ecosystem support: Kubernetes has a vibrant community, offering a wide range of tools and resources for enhancing deployments.
Declarative configuration: Kubernetes uses a declarative approach, enabling easy definition and management of the desired application state.
