devops practices:configuration as code
DESCRIPTION
The DevOps movement, like its Agile predecessor, is focused on improving the communication and collaboration between the development and operations teams responsible for different aspects of an app throughout its lifecycle. While successful DevOps initiatives start and end with organizational and cultural change, there are also common practices that are enablers and/or tools used in support of DevOps. In this session you will learn about the DevOps practice of Configuration as Code &ndash managing and maintaining application configuration as versionable assets. This session will focus on the practice of Configuration as Code, while demonstrating a few of the popular tools available today, including Opscode Chef, Powershell DSC (Desired State Configuration) and others. If you are interested in implementing a DevOps initiative in your organization, then this session is a must-see.TRANSCRIPT

Configuration as Code
• Enables you to collaborate with operations on the application environments to ensure they have the correct configuration.
• Allows “continuous deployment” and prevents “configuration drift”.
Configuration Fundamentals
Environment Configuration(Dev Test Production)
Define the Environmente.g. 3 Nodes (2 Web Severs, 1 Database Server)
Structural Configuration
Define the capabilities of the nodee.g. Windows IIS
Idempotent Automation
