6. SITUATION

7. Transitioning to the Cloud
• New organizations have it easy
• Real challenge is existing ones
• Especially in the Enterprise

8. COMPLICATION

9. IT objectives != BU
objectives

10. IT objectives
• Keeping BUs productive
• Leverage economies of scale
• Define & enforce policies

11. BU objectives
• Reducing time to market
• Facilitating experiments
• Reducing cost of failure

12. Trading off between security and
convenience means trading off
aforementioned objectives.

13. Historical failures of IT
• Stem from procurement process
• Build vs buy

14. Buy
• UX never a criteria.
• Managing supplier risk leads to big
shops.

15. Build
• No competition
• Best developers go product.

16. Different levels of risk
aversiveness

17. Selecting for a culture
• New teams (i.e., Netflix) have selected
for a certain culture
• Risk tolerance & cloud familiarity
• An Enterprise can't do this easily

18. Pets vs cattle
• Traditionally, servers are managed like
pets
• In Cloud Native architectures, servers
are managed like cattle

19. Evidence
• Private clouds built as on-demand VPS
• Used for self-service, not for Cloud
Native
• Management tactics different

20. Cost of wrongful shutdown
>> savings from shutdown

21. IMPLICATION

22. Politics & tensions

23. Politics
• Who's job is going to be made easiest?
• Effort diverted away from customers

24. Rebellion & Rogue IT

25. New Problems
• Incomplete picture
• Genentech story
• Risks, legal and other

26. Private cloud purposes

27. Private cloud
• Built to accommodate wrong pet /
cattle type
• Repatriation breaks applications
• API-compatible yet broken portability

28. SOLUTIONS

29. No silver bullet–
Awareness is a first step

30. Identify type of workload
• Pet or cattle? Is everyone on the same
page about this?
• Elastic? Regulated? Offered to
customers, or for internal use?
• What's the application lifecycle? Oneoff development, or continuously
improved?
• Special orchestration or not?

31. Picking the right cloud

32. From Amazon to Terremark
• Amazon tries hard to accommodate
pets & cattle
• Private cloud accommodates your use
case
• Terremark keeps your instances on
quality hardware

33. QUESTIONS

34. TAKEAWAYS

35. Driving fast vs driving slow

36. Disaster recovery > disaster
avoidance
• Sometimes no choice: app can't be
rewritten, tech stack doesn't support it
• Tooling needs to accommodate both
mindsets
• Scalr learned this the hard way
