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
