This document discusses setting up a CI/CD pipeline with Visual Studio Team Services (VSTS, now Azure DevOps). It begins with an overview of CI/CD and its main components like source control, build servers, and deployment environments. It then covers Continuous Integration (CI) and Continuous Deployment (CD). The document demonstrates how to automate building and deploying a simple ASP.NET web app to Azure with a VSTS CI/CD pipeline. It also references deploying a more complex sample project with full release management. Best practices discussed include automating infrastructure, building in containers, adapting pipelines to development processes, owning commits, and automating tests.
