Often Hybrid Cloud is talked about in terms of migrating entire VMs. This is fraught with problems, and can be better acheived by using automation to move a VMs configuration instead of the entire VM.

5. Why the technical debt?

6. Failure to capture configurations
• Manual Changes
• Not Captured in a repeatable format
• Changes poorly documented

7. Large cumbersome automation
• Hard to use
• Not Repeatable
• Not Idemoptent
• Not Convergent

8. Low perceived value of automation
• Quicker to do it manually
• Focuses on longer term results
• Payback period for automation

9. Images are all I need
• Golden Images
• Build images to repeat configurations

14. Problems
• VMs are heavy
• C2Cing your technical debt
• Large management overhead
• Doesn’t really realize the benefits of Cloud

16. Solutions
• Configs lighter than VMs
• Reduces moving data already in your Clouds
• Can leverage things like SCM
• Define once, run anywhere

17. Problems
• Requires discipline
• Doesn’t solve data issues
• Requires upfront investment of time

18. The question isn’t: how do I get a server,
defined by VM (or instance) into another
Cloud to serve my application

19. The question is: how do I get a server,
defined by a set of finite configurations,
into another Cloud to serve my application

20. Some things I’ve seen work
• Ignore legacy
• Focus on Cloud first
• Get development buy-in to change app stack
• Build Composable, Data Driven Automation

21. Infrastructure as Code

22. TDD of Infrastructure Code
• Test Driven Development
• Verify before deployment
• Reduce development time

23. Leverages Software Development Lifecycle
• Infrastructure Code stored in Source Control
• Who, What, When, Why, How

24. Repeatable and Reusable
• Write once, Run anywhere
• Cross Cloud, Cross Platform

25. Additional Requirements
• API Based automation
• Node based evaluation and execution
• Declaritive DSL
• Flexibility of real language
