“The key characteristics of the cloud are the ability to scale and provision

computing power dynamically in a cost efficient way and the ability of theconsumer to make the most of that

power without having to manage the underlying complexity of the

technology”from the Open Cloud Manifestowww.opencloudmanifesto.org

Case Study: Start-up Scalability

“On Wednesday, October 6, 2010, Instagram launched its mobile photo sharing service for iPhone. In six hours, the back-end operation, which was running off a single machine in Los

Angeles, was completely overwhelmed.”

http://mashable.com/2011/03/30/scaling-instagram/

“Krieger called his dedicated server representative to inquire about getting a new machine —

he was quoted a two day turnaround. Instagram, alreadyfast-approaching 40,000 users,

would need something muchsooner to meet the weekend

demand”

“Instagram officially went from a local server-run operation to an EC2 hosted shop in the wee hours of Saturday morning October 9, 2010. Doing so was much like open heart surgery, according to

Krieger.”

“Today, just six months later, Instagram’s nearly three

million users are regularlysharing north of four to five

photos a second each weekend”
