3. Devops is Hard • Even the best engineers struggle with deployments • A lot of manual work • Post-deployment monitoring • Never-ending stream of security & reliability issues
4. But it doesn't have to be
5. Kubernetes • Open-source container automation framework • Simple, Modular and Declarative • Automate as much as possible
6. Imperative Systems • Create VPS instances for all of them • Manually install dependencies • ConGgure environment • Some automation possible • Still need to react in case something goes down
7. Desired State • Tell Kubernetes what you want,
 not what to do • If something blows up, • Kubernetes will automatically Gx it • Will always go back to desired state
8. Concepts
9. Images & Containers • Represents application environment • Includes all dependencies • Isolated and bare minimum • We'll be using Docker
10. Pods & Clusters • One or more containers deployed together • Representing an instance of your application • One IP per pod • One machine / node • Cluster is a group of nodes / pods
11. Services • Named high-level application abstraction • Maps actual requests to pods • Load-balancing
