SLIDE 2

 Significant growth in number of Cloud IaaS

providers

 Different providers, different API, different

resource offering types, different pricing structures...

 Complex resource choices

(hardware spec, os, hosting cost, bandwidth cost, data throughput, value-added services, etc…)

 c1.xlarge (high cpu extra large)

8 cpu virtual cores
$0.66
