The cloud is great. Long live the cloud. Just to illustrate how popular the cloud really is, today the Amazon AWS servers are down. Tech startups and SaaS (Software as a Service) tech companies have been saving a ton of money by moving their online services to AWS instead of buying, licensing , and maintaining their own serves, and the primary target of this move is Amazon AWS. About a year ago I heard a statistic that Amazon AWS hosts more data on the Internet than the next 28 services combined! That's huge!
Lesson learned: Redundant services are still a good plan even in these days of the cloud.
