Introduction to Kubernetes

• Definition Kubernetes is an open-source
  container orchestration platform that automates
  the deployment, scaling, and management of
  containerized applications.
• Why it matters Designed to manage complex
  microservices architectures across distributed
  environments.
• Visual Simple architecture diagram of Kubernetes
  with master and worker nodes.

Core Components of Kubernetes

• Key Components
• Pod Smallest deployable unit.
• Node A worker machine.
• Cluster A set of nodes managed by Kubernetes.
• Kubelet, API Server, Scheduler, etc.
• Visual Component relationship diagram.

What is Reliability in Systems?

• Definition The ability of a system to
  consistently perform its intended function.
• Key elements
• Uptime and availability
• Fault tolerance
• Self-healing
• Scalability
• Visual Pillars of reliability diagram
  (Availability, Scalability, Recovery, Monitoring)

How Kubernetes Supports Reliability Self-Healing

• Features
• Automatically restarts failed containers.
• Replaces and reschedules containers on failed
  nodes.
• Kills containers that dont respond to health
  checks.
• Impact Minimizes downtime and ensures service
  continuity.
• Visual Animated flow of failed pod getting
  replaced.

Scalability and Load Balancing

• Auto-scaling Based on CPU/memory usage or custom
  metrics.
• Load balancing Distributes traffic across
  healthy pods.
• Horizontal Pod Autoscaler (HPA)
• Visual Diagram of load balancing and autoscaling
  process.

High Availability Rolling Updates

• HA Deploy applications across multiple nodes and
  zones.
• Rolling Updates Deploy new versions without
  downtime.
• Rollback Revert to the previous version in case
  of failure.
• Visual Timeline showing a rolling update vs
  downtime.
