Kubernetes in One Shot

Kubernetes (often abbreviated as K8s) is an open-source platform designed to automate the deployment, scaling, and management of containerized applications. It acts as a container orchestration system, handling the complexities of running and managing applications composed of multiple containers across a cluster of machines.

Key aspects of Kubernetes:

• Container Orchestration:

  Kubernetes automates the deployment, scaling, and operational tasks of containerized applications. This includes tasks like managing container lifecycles, ensuring high availability, and handling load balancing.

• Declarative Configuration:

  Users define the desired state of their applications and infrastructure using configuration files (YAML or JSON). Kubernetes then works to achieve and maintain this desired state, automatically handling changes and self-healing when issues arise.

• Portability:

  Kubernetes allows applications to be deployed consistently across various environments, including on-premise data centers, public clouds (like Google Cloud, AWS, Azure), and hybrid cloud setups.

• Self-Healing:

  Kubernetes can automatically detect and recover from failures, such as restarting failed containers, replacing unhealthy nodes, and ensuring that the specified number of application instances are always running.

• Scalability:

  It provides mechanisms for easily scaling applications up or down based on demand, automatically adjusting resource allocation to meet varying workloads.

• Service Discovery and Load Balancing:

  Kubernetes includes built-in features for service discovery, allowing different parts of an application to find each other, and for load balancing traffic across multiple instances of a service.
