This document provides an introduction to modern DevOps technologies. It discusses DevOps concepts like source code management using Git, different methods of deploying programs including using bare metal servers, virtualization, containers, and cloud functions. Specific container and container orchestration technologies like Docker and Kubernetes are explained. Continuous integration and continuous delivery (CI/CD) practices are also introduced. The presentation includes an agenda with slides on these topics and ends with a question and answer section and announcement of a Docker workshop to deploy an HTTP server container.

12. How to deploy a program?
Compiled Languages
- Compile
- Upload executable to server
Interpreted Languages
- Upload (or `git pull`) source codes to the server

13. Bare Metal Server
● Pre-cloud era
● Install OS and dependencies on a machine
● One machine - one server
● Expose the network to the internet
● Colocation/on-premise
● SSH/FTP/Git to the server

14. Virtualization
● One machine - many servers
● One machine multiple customers
● VPS / Cloud
● SSH/FTP/Git to the server
IaaS

15. Containers
● Docker / Kubernetes
● Auto deployment
● Auto scale (automatically spawn new workers)
● Pay on number of nodes
● Infrastructure as code! (IaC)
PaaS/ CaaS

16. Cloud Functions
● Write your code and deploy!
● Auto deploy
● Auto scale
● Pay per request
● No infrastructure work!!
FaaS

18. Virtualization vs Containers

19. Benefits of using Docker
● Consistent development, testing, and production environments
● Docker Engine can run on Linux, MacOS, and Windows
● Language and application dependencies are pre-install
from docker images
● Run different versions of same programming language
on the same machine
