Exposing Applications with Services

When you deploy applications in Kubernetes, your Pods can come and go. They get new IPs, they scale up or down, and they might even crash and restart.

This creates a challenge: how do other parts of your application, or external users, consistently find and communicate with these ever-changing Pods?

Kubernetes Services solve this problem by providing a stable network abstraction over a set of Pods. Think of a Service as a single, unchanging IP address and DNS name for your application.

• Services act as load balancers, distributing traffic to healthy Pods.
• They ensure your application remains reachable even if individual Pods change or fail.
