22. Why do some Cloud providers
use Amazon and others do not?

23. Why do some Cloud providers use
Amazon and others do not?
• Don’t kid yourself – cost is an important consideration!
• Margins are thinner and managing all aspects of cost
is a first for application providers
• Security concerns –
• Latest one: MIT Technology Report – 46% of
virtualized environments in an EC2 test environment
could be hacked
• CIO’s read this stuff and within hours it comes up
in questions to us!
• Remains a concern long after the issue has been answered

Kaizen their mistake?

28. Don’t forget about the people
• Do your due diligence on the technology but
do NOT forget about the people part
• What is their tenure? New technologies tend to have people jump
around a lot while their skills are considered fresh
• Cloud is new but not that new…
• Where did they come from?
• Have they built/delivered scalable solutions or applications?
• SuccessFactors Alumni:
• eBay, Yahoo!, Oracle, Informatica
• Ran Large and Small Engineering teams, CIOs (multiple times), Security
focused
