How I Learned to Stop Worrying and Love the Cloud
- 1. How I learned to stop worrying and love the cloud Cloudops 17-‐03-‐2011
- 3. An Epiphany 389 Boulder Creek Fault
- 4. An Epiphany 389 389 Boulder Creek Fault
- 5. An Epiphany 389 389 Boulder Creek Fault So I asked for more informaGon…
- 6. And the first few pages of the presentaGon were pictures of machines
- 7. To me it looked like this And I decided to understand what was wrong
- 8. What’s wrong with Hardware 1. It’s a fixed asset that needs to be planned
- 9. What’s wrong with Hardware 1. It’s a fixed asset that needs to be planned – In most cases, you cannot plan for any Gmeframe
- 10. What’s wrong with Hardware 1. It’s a fixed asset that needs to be planned – In most cases, you cannot plan for any Gmeframe – So people overplan (too many machines, too many top-‐line configuraGons)
- 11. What’s wrong with Hardware 1. It’s a fixed asset that needs to be planned – In most cases, you cannot plan for any Gmeframe – So people overplan (too many machines, too many top-‐line configuraGons) – And you pay (or commit to pay) in advance. Bite-‐ size increases difficult because of approval
- 12. What’s wrong with Hardware 2. Once the machines are there
- 13. What’s wrong with Hardware 2. Once the machines are there – ApplicaGons and data will fill them like gas
- 14. What’s wrong with Hardware 2. Once the machines are there – ApplicaGons and data will fill them like gas – If your requirements change, machines are simply unused
- 15. What’s wrong with Hardware 2. Once the machines are there – ApplicaGons and data will fill them like gas – If your requirements change, machines are simply unused – You cannot scale up fast and you certainly cannot scale down at any speed
- 16. What’s wrong with Hardware 3. Once a machine is installed
- 17. What’s wrong with Hardware 3. Once a machine is installed – You program and configure it as if it will remain the same forever
- 18. What’s wrong with Hardware 3. Once a machine is installed – You program and configure it as if it will remain the same forever – SoXware and hardware become too interconnected someGmes even by design
- 19. What’s wrong with Hardware 4. There is NEVER an opGmal to think or act differently
- 20. What’s wrong with Hardware 4. There is NEVER an opGmal to think or act differently – If you introduce the idea of cloud, people will approach as if it were alternaGve hosGng and your vendor will gladly underprice to keep you hooked
- 21. What’s wrong with Hardware 4. There is NEVER an opGmal to think or act differently – If you introduce the idea of cloud, people will approach as if it were alternaGve hosGng and your vendor will gladly underprice to keep you hooked – Your applicaGon developers will predict mayhem
- 22. What’s wrong with Hardware 4. There is NEVER an opGmal to think or act differently – If you introduce the idea of cloud, people will approach as if it were alternaGve hosGng and your vendor will gladly underprice to keep you hooked – Your applicaGon developers will predict mayhem – As a compromise, your tech people (you?) will propose to build an internal cloud system…
- 23. It’s not an evoluGon
- 24. It’s not an evoluGon • Using the cloud like you use a fixed asset system will never yield any advantage
- 25. It’s not an evoluGon • Using the cloud like you use a fixed asset system will never yield any advantage • You have to think and build differently
- 26. It’s not an evoluGon • Using the cloud like you use a fixed asset system will never yield any advantage • You have to think and build differently • Learn from people who can afford to start from scratch (start-‐ups)
- 27. How to think right • Hardware is soXware (it always sort of was…)
- 28. How to think right • Hardware is soXware (it always sort of was…) cpu

- 35. What do you get? • It’s basically an object or a class.
- 36. What do you get? • It’s basically an object or a class. – You can construct it
- 37. What do you get? • It’s basically an object or a class. – You can construct it – It can do inheritance/delegaGon (get the code to do your work from a repository, assume a role)
- 38. What do you get? • It’s basically an object or a class. – You can construct it – It can do inheritance/delegaGon (get the code to do your work from a repository, assume a role) – Get the data it needs (from scratch or cloning it from another object)
- 39. What do you get? • It’s basically an object or a class. – You can construct it – It can do inheritance/delegaGon (get the code to do your work from a repository, assume a role) – Get the data it needs (from scratch or cloning it from another object) – ParGcipate in the system unGl told to stop or it crashes

- 79. How to get there • Start with what you build yourself and experiment
- 80. How to get there • Start with what you build yourself and experiment • Try to expose yourself to startups and see how they do what they do
- 81. How to get there • Start with what you build yourself and experiment • Try to expose yourself to startups and see how they do what they do • If you use vendors system and just install and maintain them, educate yourself and try to find a vendor that thinks right
- 82. How to get there • Start with what you build yourself and experiment • Try to expose yourself to startups and see how they do what they do • If you use vendors system and just install and maintain them, educate yourself and try to find a vendor that thinks right • If your revenue/job depends on the inefficiency being solved, start to pivot
