9. Kubernetes Services
• ClusterIP: Exposes the service on a cluster-internal IP.
• NodePort: Each Node’s IP at a static port (30000-
32767).
• LoadBalancer: Exposes externally using a cloud
provider’s load balancer.
• Ingress: Collection of rules that allow inbound
connections to reach the cluster services. (Think of it as
a 1:many) relationship between LB and service.

10. Prometheus
• Monitoring for Kubernetes, and your applications running on K8s.
• Think of it like datadog (or Nagios)…

11. Helm
• Package management for Kubernetes and Cloudnative apps.
• Think of it like npm….but for K8s.

12. Thank you!
