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.
