The cloud came tumbling down for many startups and sites based on the Amazon EC2 API today. There's a perception that storage and scaling in the cloud is supposed to mean we don't have to deal with outages. It's pretty clear that's not actually the case, as some popular sites like Heroku and Foursquare nosedived.
After Facebook announced that apps can be deployed to Heroku, the cloud platform saw tremendous growth. It's on pace to add five times as many applications in 2011 as it had last year, likely fueled by being the only cloud service supported from within Facebook. The two companies introduced a new concept in developer relations, the "click-to-cloud" sample app.
