The Context…
Conditions of too much uncertainty

▶Buzzword + hype
– own convenience (even us)

▶Cloud is young and
complex concept
– “lack” of history
– it is still changing

▶Markets = non-additive
ecosystems
– dynamic, complex and interrelated
– credible/workable comparisons?
– everyone claims to be a “leader”
