 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.
Introduction to Kubernetes

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

 Definition: The ability of a system to consistently perform its intended function.
 Key elements:
o Uptime and availability
o Fault tolerance
o Self-healing
o Scalability

Monitoring)
What is Reliability in Systems?

How Kubernetes Supports Reliability –
Self-Healing
 Features:
o Automatically restarts failed containers.
o Replaces and reschedules containers on failed nodes.
o Kills containers that don’t respond to health checks.
 Impact: Minimizes downtime and ensures service
continuity.
• Visual: Animated flow of failed pod getting replaced.

 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.
Scalability and Load Balancing

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.

 Built-in support for monitoring tools:
o Prometheus, Grafana, Fluentd, ELK stack
 Logging and Metrics: Enable alerting, performance
monitoring.
• Visual: Stack diagram of Kubernetes + Monitoring

Monitoring and Observability

Summary & Takeaways
 Kubernetes enhances system reliability through:
o Self-healing
o Automated scaling
o High availability
o Seamless updates
o Real-time monitoring
 Quote: “Kubernetes isn’t just about running containers, it’s about
running resilient systems.”
• CTA: Explore Kubernetes in action with real-world case studies
or labs.
