Containers & Orchestration

Containers package applications and dependencies together, making them portable and consistent across different environments.

What Are Containers?​

  • Lightweight, standalone, and executable packages.
  • Encapsulate code, runtime, libraries, and configs.
  • Docker is the most widely-used container runtime.

Why Use Containers?​

  • Consistency between dev and prod environments
  • Fast, scalable, and efficient deployments
  • Isolation and security

Orchestration with Kubernetes​

As applications grow, managing many containers becomes challenging. Orchestration automates deployment, scaling, and management.

  • Kubernetes is the leading orchestration platform.
  • Coordinates containers across multiple machines.
  • Handles load balancing, scaling, rollouts, health checks.

Other Tools​

  • Docker Compose (development)
  • Amazon ECS, Azure AKS, Google GKE (managed Kubernetes)

Containers and orchestration are vital for modern DevOps and microservices architectures!
