  6. Manual configuration management doesn’t cut it anymore • Modern change management requires automation. • Individuals cannot manage thousands of instances manually.

  7. Automated systems management is one of the top priorities for global technology infrastructure decision makers.

  8. You need to help the “bad good guys”

  9. Infrastructure is now defined by models Source: Lead The I&O Software Revolution With Infrastructure-As-Code Forrester report

  10. Source: The Quest For Speed-Plus-Quality Drives Agile And DevOps Tool Selection Forrester report

  11. Transition the I&O mindset • Adopt immutable/composable philosophies. • Modern infrastructure has a much quicker life cycle. • Assume rapid creation/destruction of systems. • Nothing is failproof. • Developers don’t always write code: They rely on automation. • Version control • Application release automation/continuous delivery • Configuration management

  12. However, it’s a bit of a “Wild West” Source: The Forrester Wave™: Continuous Delivery And Release Automation, Q3 2017 Forrester report

  13. 24% of decision makers never use change/configuration management tools.

  14. Agenda • The changing role of I&O in an automated world • The tools themselves • Next steps

  15. Configuration management tool sets • Chef, Puppet, Ansible, Salt, CFEngine, and PowerShell DSC • Some tools are more developer- or operations-friendly. • Integration with other tools is essential.

  16. Chef and Chef Automate • Broad support for various operating systems, containers, and cloud services • “Cookbooks” available through Chef Supermarket • Automate adds web-based GUI and dashboard for compliance visibility • Strengths • Deployment support (available as SaaS) • Monitoring and governance • Community support

  17. Puppet and Puppet Enterprise • Focuses on broad platform support; if it’s reachable by IP, it should be configurable. • Puppet Forge provides thousands of modules. • Puppet Enterprise adds web-based UI that provides visibility into configurations, dependencies, and events. • Strengths • Drift correction • Out-of-the-box third-party plug-ins • Monitoring and governance

  18. Ansible and Ansible Tower • Focuses on minimalism and ease of use • Does not require agents — configurable via SSH and WinRM • Code can be written in multiple languages. • Ansible Tower adds analytics and compliance capabilities. • Strengths • Version control • Vulnerability/defect tracking

  19. Salt and SaltStack Enterprise • Emphasizes choice: run with or without agents. • Operations-first focus • Reactor: events-driven engine • SaltStack Enterprise adds enterprise GUI and API for integration. • Strengths • Analytics and reporting • Vulnerability tracking • Compliance enforcement

Microsoft PowerShell DSC and Azure Automation • PowerShell DSC • Primarily supports Windows, but recent support added for Linux. • Code can be written in PowerShell or Python. • Azure Automation • SaaS-based offering • Includes change tracking, inventory, and update management • Strengths • Analytics and reporting • Vulnerability/defect tracking

  22. What you should be looking for in a tool • Flexibility • Modularity • Integration with common APIs • Large community • Integration with service delivery • Not necessarily the big players

  23. Agenda • The changing role of I&O in an automated world • The tools themselves • Next steps

  24. Good and bad infrastructure automation • Good: • Automatic changes • Minimal or no approvals for minor changes • Consistent models from dev to production • Cross-silo • Bad: • Manual changes • Approvals for all changes, regardless of criticality • Inconsistent models at different levels • Siloed workforce
