• What is multi-cloud?

• Certain scenarios with demos.
• The hard problems
• Summary

4. WHAT IS MULTI-CLOUD?
The ability of an organization to mix and match the
computing services from different cloud
providers to provide maximum business
value and customer happiness.
@tushardadlani

5. DOYOU NEED IT?
1. Do you have public and internal facing
applications?
2. Do you fear being locked-in to a single cloud provider?
3. Do your applications have different security or
compliance requirements?
4. Do you need specialized services from some cloud
provider?

7. CF APPLICATION PROMISE
Write once, run anywhere.
@tushardadlani

8. SCENARIO - 1
My application used to run on our X cloud on my
private infrastructure and now my company wants
me to move it to cloud providerY.
@tushardadlani

9. SCENARIO - 1-BEFORE CF
1. This will take few months.
2. Now I have to learn about cloud providerY.
3. How do I securely run it here?
@tushardadlani

10. SCENARIO - 1-AFTER CF
cf push
@tushardadlani

11. SCENARIO -2
I ran out of resource quotas on cloud provider X,
though IT told me that we have some spare quota
on cloud providerY.
@tushardadlani

12. SCENARIO -2 - BEFORE CF
1. How do I use that spare quota?
2. Cloud providerY won’t work with my existing
automation.
@tushardadlani

13. SCENARIO - 2 - AFTER CF
cf push
@tushardadlani

14. SCENARIO - 3
Our service has applications, X andY. My manager
told me, they now need to be “A” compliant.
@tushardadlani

15. SCENARIO - 3 - BEFORE CF
1. I know nothing about compliance A.
2. Now I need to rewrite my entire application with
all these considerations listed in compliance A.
3. I will wait till the other team figures out
compliance A.
@tushardadlani

16. SCENARIO - 3 - AFTER CF
cf push
@tushardadlani

17. SCENARIO - 4
I want to split the traffic of 1000s of my applications
across cloud provider X and cloud providerY.
@tushardadlani

18. SCENARIO - 4 - BEFORE CF
1. My application logic and deployment needs to be
rewritten to be cloud agnostic.
2. We don’t have all the skills on our team to
understand cloud X andY.
@tushardadlani

19. SCENARIO - 4 - AFTER CF
Custom DNS based round robin
cf api api.cloudA.com && cf push
cf api api.cloudB.com && cf push
Note: BOSH has an upcoming proposal for multi-cloud CPI
@tushardadlani

20. SCENARIO - 5
Application A now needs capability P, that is available
only on cloud provider X and application B needs
capability Q that is only available on cloud providerY.
@tushardadlani

21. SCENARIO - 5 - BEFORE CF
Custom application logic that integrates with each
cloud providers backend logic independently.
@tushardadlani

22. SCENARIO - 5 - AFTER CF
Cloud foundry applications with user provided
services.
@tushardadlani

23. OTHER SCENARIOS
1. Dev, test, production
2. Scale testing
3. Performance testing
@tushardadlani

24. DEMO
@tushardadlani
Disclaimer: None of the demos are directly targeting any vendors. It’s just what I have access to.

25. ELEPHANTS INTHE ROOM
1. Persistent data
2. Cloud foundry operations
3. Infrastructure stability

26. PARADOX OF CHOICE
Autonomy and Freedom of choice are critical to our well being, and
choice is critical to freedom and autonomy. Nonetheless, though
modern Americans have more choice than any group of people
ever has before, and thus, presumably, more freedom and
autonomy, we don't seem to be benefiting from it psychologically.
— quoted from Ch.5,The Paradox of Choice, 2004

27. SUMMARY
• Cloud foundry applications are extreme portable.
• Easy to achieve multi-cloud for application logic
portability.
• Persistent data is a hard multi-cloud problem.
• Have a multi-cloud strategy if and only if you need it.
