Lucas123 writes: As enterprises increasingly consider moving their computing infrastructure to the cloud, IT professionals wonder whether they should follow the migration. Jake Robinson said he remembers the day he really understood what it means to work on "the other side of the cloud." It was Thanksgiving, a couple of years ago. A customer posted an iPhone app designed to give users access to coupons and discounts the following day, Black Friday. The retailer had vastly underestimated demand for the app, and the ASP's database crashed. A solutions architect, Robinson was called in and spent most of the holiday tuning the client's database server to handle the traffic. Computerworld spoke to a half-dozen IT professionals who worked for cloud service providers to get their their experiences.
