5. How Puppet Enterprise Works

6. What is Patch Management?
And what is it becoming?

7. What is Patch Management?
• Traditional Model
Application
s
OS
OS Updates

8. Windows Server Patch Management Today
• Patches stored in a central repository
– Windows Update (Internet)
– Internally hosted
• Distributed to end user systems on a schedule
• Microsoft Technologies
– Windows Server Update Services (WSUS)
– System Center Configuration Manager (SCCM)
– Extensive research and experience

9. Windows Server Update Services (WSUS)
• Updates distributed via Microsoft Update
• WSUS Server stages updates
• Updates pulled by clients
– Similar to Automatic Updates on desktops

10. System Center Configuration Manager (SCCM)
• Integrates with WSUS for software updates
• Wizard-driven configuration
– Deployment targets
– Update Rules
• Manages WSUS client behind the scenes. Can initiate WSUS
runs

11. Traditional View: OS as Platform
Application
s
OS

12. Can we alleviate this tension?

13. A Different Conceptual Model
OS
Applications
• OS, applications are interdependent
• Work together towards a common end

14. Extend the Patch Concept
OS Updates
Application Updates

15. Application Update Challenges
• Inconsistent formats
– .zip, .exe, .msi
• No central location
• No unified delivery mechanism

16. Package Management
• Package Management
– Centralized distribution of packages from curated repositories
– Package: Atomic bundle to deliver software
• Versioned
• Metadata (dependencies)
• Allow scripts
– Create repositories of packages
– Machine-implemented

17. Chocolatey
• Package Management for Windows
• Common format for software delivery
– Versioned
– Metadata (dependencies)
– Allow scripts
• Defines repositories
– Public, internet-hosted
– Private, internal

18. Install Notepad++ with Chocolatey

19. But wait, there’s more
OS
ApplicationsApp Configuration
OS Configuration

20. How do we patch configuration?

21. Configuration Patch Requirements
• Versioned
• Coupled to OS, App versions
• Machine-driven delivery mechanism

22. Puppet Enterprise

23. Enabling Technologies
• Infrastructure as Code
• Package Management

24. Puppet: Infrastructure as Code
• System state defined in software
– Stored in Version Control System (VCS)
• Microsoft Team Foundation Server (TFC), Git
• Centralized location
– Versionable
• Commit hash
– Dependency resolution
• System state implemented by machine
– Puppet agent

25. Puppet Manages Configuration State

26. Puppet Manages Package State

27. Desired State Configuration (DSC)
• Windows PowerShell Desired State Configuration
• Microsoft Implementation of Infrastructure as Code
• Native support for many core types
– Users, Files, Registry settings, etc.
• Active development of extensions
• Integration with Puppet

28. Look Familiar?
• Configurations
– Versioned
– Centralized
• Application Packages
– Versioned
– Centralized
• OS Patches
– Versioned
– Centralized

29. What’s missing?
• Unified management
• Visibility
• Security and Compliance
• Heterogeneous Environments

30. Puppet Enterprise Ties it all Together

31. Convergence of Functionality
• Infrastructure and Applications look like OS Patching
• WSUS client
– Query Windows Update service for new packages on a schedule
– Apply new updates when available
• Puppet agent
– Query puppet master for new configuration on a schedule
• New versions of application packages
– Apply new configuration when available

32. Aren’t OS Patches Just Packages?

33. Use the Right Tool for the Job
• Using package management is not a replacement for
Windows OS patch management
– Reinventing the wheel
– Increased burden on Operations personnel
• Manage OS patches individually
• Maintain Puppet code to manage OS patches individually

34. Rich Ecosystem of Windows Resources
• WSUS Client Module
– Manage configuration of Windows Updates
• Chocolatey
– Manage application updates
• Desired State Configuration (DSC)
– Manage Windows State
• PowerShell support
– Automate arbitrary configuration requirements

35. Manage WSUS Client

36. The Puppet Approach
• Define OS update policies in Puppet code
• Manage OS patch policy as part of overall system
– Application versions
– System, application configuration
• Native Puppet Types
• DSC
• Continually enforce state of OS patching policy
• Report on changes to update policies

37. Puppet Enterprise allows you to more
effectively use proven Microsoft technologies
to integrate OS patch management into a more
unified approach to platform management.
