Introduction to Kubernetes & Why It Matters
Understand the challenges Kubernetes solves, its benefits, and its role in modern cloud-native development.
Welcome to Kubernetes!
Welcome to the world of Kubernetes, often shortened to K8s! It's an open-source system designed to automate deploying, scaling, and managing containerized applications.
Think of it as an operating system for your data center, but specifically for containers.
Life Before K8s
Before orchestration tools like K8s, managing many containers was tricky. Imagine you have 100 containers running different parts of your app.
- How do you ensure they all start correctly?
- What if one crashes?
- How do you update them without downtime?
- How do they find each other?
These are the challenges K8s was built to solve.
