As many of you already know, the recession is having a widespread effect on the technology industry. One example is that many companies are now looking into green IT in order to save money on data hosting. Rhonda Ascierto, senior analyst at Datamonitor, believes that companies "facing critical limitations with their existing data centres, such as a shortage of floor or rack space, are now looking at options such as IT leasing, managed services, virtualisation, cloud computing and software-as-a-service (SaaS)."

With SaaS solutions, the vendor's central data center provides the computing resources to run the application. This means that customers don't have to consume critical resources to generate the power for their own host machine. Not only that, but the redundant backup power and HVAC systems are also handled by the vendor, saving customers money that they could really use in this economy.
