1. Give a man a Container and you keep him busy for a day

2. Teach a man Kubernetes and you keep him busy for a lifetime

Kubernetes is not a “CI/CD”, “Micro-service” focused container cloud

• kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services.
  It facilitates both declarative configuration and automation,
  letting us run distributed system resiliently that scale to meet users’ demand.
• kubernetes (k8s) is an open-source platform for containerized application deployment, automation, management, and scaling.
• Kubernetes groups containers into logical clusters for easy management and discovery. K8S can operate both in cloud and
  on-premise environments, including hybrid clouds.

Key features of Kubernetes include:

Load Balancing and Service Discovery:

  - Automatically assigns DNS names, IP addresses, and load-balances to pods.

Automatic Bin Packing:

  - Ensures the availability and optimization of resources by placing containers based on 
    their resource requirements.

Self-Recovery:

 - Restarts failed containers, replaces containers after node failures, and removes containers 
   that fail health checks.

Rollout and Rollbacks Automation:

 - Rolls back to previous versions when issues occur and prevents system failure by 
   running modifications.

Batch Execution and Scaling:

 - Enables you to scale applications manually or automatically and manages batches and 
   Continuous Integration (CI) workloads.

Kubernetes is a declarative platform

- brain for your distributed container deployment

- Container Centric DevOps/Workload Orchestration System

- Platform for building Platforms
