DSC – Definition “Standard Space management to manage heterogeneous networks containing different types of Servers connected with Clients of different form factors. ” Servers • Windows/Linux etc. Clients • Windows/i. OS etc Form Factors • PC/Servers/Tablet/Phones etc.

Why DSC? Life with non. Registered (mobile) Devices Different (including non-Windows) type of devices needs to be handled Life in the Cloud… Rapid change, at scale with, constant failures Requirement Need of an agent to “Make It So” Want to compare Actual and Expected States easily Need a language to express custom desired state easily

What is “Make it so”? • With DSC we just define in configuration – “Hey, you are a web browser, this is what you should look like. Get to it, stay that way. ” • Logic of making configuration in that way lies with ‘Local Configuration Manager’ on Client Machines. • Making logic on client side enable us to control device specific behavior implementation

How DSC help? One Stop Solution to Manage Enterprise Cloud BYOD - non -Win Devices Laptop (VPNs) Desktop/ Server Option of correcting configuration drift when it occurs, or just report on configuration drift, to ley it know to admins that it has occurred

How DSC help? One Stop Solution to Manage Enterprise Cloud BYOD - non -Win Devices Laptop (VPNs) Desktop/ Server Allows you to describe the desired state of your environment by using this new power shell syntax Option of correcting configuration drift when it occurs, or just report on configuration drift, to ley it know to admins that it has occurred

Where DSC can be used? Install or remove server roles and features Manage registry settings Manage files and directories Start, stop, and manage processes and services Already Supported in GP Manage local groups and user accounts Install and manage packages such as. msi and. exe Manage environment variables Discovering the actual configuration state on a given node Fix a configuration that has drifted away from the desired state

How DSC works? 3 Phase Model Authorizing Phase “Make It So” Phase Staging Phase

How DSC works? Authoring Phase In this phase Admin creates the DSC configuration locally, through Power. Shell or by third party languages/tools. The output is one or more MOF (Management Object Format) files, the format which is consumable by DSC.

How DSC works? DC / Pull Server Authoring Phase Staging Phase In this phase DSC data (MOF files) is staged for Deployment – • Push Model – On DC • Pull Model – Dedicated Web Server (IIS)

DSC data is either pulled or pushed to the “Local Configuration Store” and contains the current, previous and the desired (DSC) state configuration. How DSC works? DC / Pull Server Authoring Phase Staging Phase “Make it So” Phase Enterprise The configuration then gets parsed and the relevant (WMI) provider implements the change and “makes it so”.

Power Shell Extension • Support type definitions for eg. Configuration types • New language/constructs specific to authoring of the Configuration scripts. Eg. configuration My. Website { node ("Web. Server 1", "Web. Server 2") { Windows. Feature IIS { Ensure = "Present" Name = "Web-Server“ } } } @ITPro. Guru

As Dan the developer, I can easily author a DSC script reusing DSC resources from a public or private gallery, so that I can quickly and easily write DSC scripts with very little custom code.

Author a DSC script WITHOUT DSC Resource

… reusing DSC resource/s - I I can Find DSC resources from Gallery by Search Term/Name/Tag I have a rich set of resources to use from Day 1 that replace my RM actions [see next slide]

Rich set of DSC resources replacing RM actions No. 1 RM Tool Application Pool Tag IIS RM Action Create/Config/Start/Remove App Pool RM Customer Usage 1. Very Frequent 2 Web Application IIS Create/Configure/Remove Web Application 1. Very Frequent Web. Deploy 3 Website IIS Create/Configure/Remove/Start/Stop/Restart Website 1.

Existing PS Modules/DSC resources ported to gallery I can port PS modules & DSC resources from Technet Script center to the gallery.

reusing DSC resource/s - II WITH DSC Resource I can install multiple resources & modules that my DSC script depends on before deploying to a node in push mode.

Power. Shell Gallery http: //www. powershellgallery. com/

… from a public or private gallery - I I can install DSC resources from the Gallery

… from a public or private gallery - II I can choose the URI of the public/private gallery or the path [like a build drop path] that I want to install the module from.

… from a public or private gallery - III User can choose to not install module from the public/private gallery but to directly copy all the required bits directly from a build drop path.

What does a Script look like? “My. Configuration. webserver” Configuration Block… Resource Block… (AKA: Compilation Job) Within a Configuration block, you can do anything that you Node block… normally could in a Power. Shell function https: //azure. microsoft. com/en-us/documentation/articles/automation-dsc-overview/
