The document discusses applying DevOps principles in established corporate organizations, noting that such organizations typically have heterogeneous environments and teams, focus on integration, have a top-down management approach, and lower release frequencies compared to modern firms. It also outlines how to establish foundations of DevOps like configuration management, continuous integration and delivery, and monitoring through standardized templates, version control, and automation.

1. Dave Sayers
Applying DevOps principles in established
corporate organisations

2. “There is a difference in DevOps
approaches between organisation
where IT is not a core competency –
and those where it is”

3. Agenda
• Why?
• Characteristics of traditional and
modern firms
• Foundations of DevOps approaching in
the enterprise
• Importance of configuration
management
• Brief look forward

4. Why?
• Fast flow of planned change
• Efficiency
• Repeatability
• Audit
• Compliance
• Security, etc.

5. Characteristics of the enterprise

6. Heterogeneous environments

7. Focus on integration

8. Management approach

9. Heterogeneous Dev and Ops teams

10. Low frequency of releases

11. Manual Processes

12. Established Organisations
• Heterogeneous Environments
• Focus on integration
• Top down approach
• Low frequency of releases
• Manual processes
• Heterogeneous Dev and Ops
teams
• “Buy not build”

13. Characteristics of Modern firms
• Smaller number of decoupled
products
• More homogeneous dev and ops teams
• Built with automation in mind
• High deploy rates
• Built on modern / opensource
technology

Model Driven Deployments
• To ensure consistency – always deploy the same thing!
• Data driven
• Templates created that define infrastructure or application
configuration
• Contain the complete configuration for a target technology
• Deltas become part of the template – so configuration changes
are not made in isolation
