This month we had Don Jones, an instructor, speaker and co-author on PowerShell and Microsoft MVP since 2003. Don helps run PowerShell.org, the PowerShell Summit events and the Scripting Games. Catch Don’s video training for PowerShell through Pluralsight, and the YouTube channel.
Don talked about Desired State Configuration (DSC) and DevOps.
DSC is a new management platform in Windows 2012 where PowerShell enables deploying and managing configuration data for software services, it also manages the environment in which these services run.
DSC provides a set of Windows PowerShell language extensions. These are new Windows PowerShell cmdlets and resources used to configure software environments. These cmdlets also provide a means to maintain and manage existing configurations.
DevOps takes Application Lifecycle Management (ALM) and Agile methodologies to a comprehensive platform by addressing the needs of the digital business along with the technology of DSC. These two technologies run in tandem; DSC configures and maintains the virtual front-end environment while DevOps manages the collaboration between different apps and environments. The benefits of DSC as a part of DevOps are:
- DevOps manages the critical importance of transparency, communication and collaboration between development and operations teams.
- DevOps runs the inclusion of the project’s business owner and other critical groups such as security (DevOpsSec), networking and compliance.
- DevOps reduces managing unique objects such as assigning IP addresses and DNS Servers.
- DSC can assign computer names, IP-Addresses,etc
- DSC can deploy the image and join the computer to Active Directory.
- DSC can do separate things for different applications such as applying baseline security policies and installing updates.
- Scripts no longer have to be told how to install, they are instructed to install and they figure it out.
An example is to picture DSC as a front-end. This front-end acts and feels much like group policies does today and DevOps is the back-end database.

Don’t waste time learning Exchange Server, Microsoft is no longer developing future releases of Exchange, it is most likely re-developing into a hosted email solution.
