“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

Another way to think about it...
...what interfaces with the service?
End User Software-as-a-Service
API Platform-as-a-Service
Operating System Infrastructure-as-a-Service

Case Study: Start-up Scalability
![Page 25: "To The Cloud!"](https://reader033.fdocuments.us/reader033/viewer/2022052618/554efd31b4c90577698b4c3e/html5/thumbnails/25.jpg)
“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”
![Page 26: "To The Cloud!"](https://reader033.fdocuments.us/reader033/viewer/2022052618/554efd31b4c90577698b4c3e/html5/thumbnails/26.jpg)
“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.”
http://mashable.com/2011/03/30/scaling-instagram/
“Today, just six months later, Instagram’s nearly three
million users are regularlysharing north of four to five
photos a second each weekend”
