Why mobile devices need single-sign-on technologies

As the iPad's popularity continues to grow and security concerns increase, providers of cloud-based single-sign-on (SSO) solutions face a prime business opportunity: to make their tools the weapons of choice for next-generation mobile identity management and authentication. By replacing multiple user names and passwords with one-click access to cloud-based apps like Google Apps and Microsoft’s Active Directory, cloud-based SSO solutions have earned a reputation for enhancing end-user convenience, easing the pressure on IT administration, and cutting help-desk costs.

The economics of clean-data-center innovation

Around the world, data centers consume around 1.5 percent of total electricity demand, a figure that’s expected to increase significantly. Greenpeace predicts power consumption will grow 19 percent by 2013 to 31 gigawatts. To cut power and, with it, costs, tech titans like Google, Apple, and Facebook are aggressively pursuing strategies to cut electricity use by greening their data centers. But do energy-efficiency gains justify huge capital outlays? This report attempts to answer that question by looking at the ways in which companies are greening their data centers and attempting to achieve social, economic, and environmental value.…

As is the case in any market, disruption calls for smart innovation, and several companies are rising to the task. Challenges await, including trade wars, funding shortages and other roadblocks to commercialization. The clear winner will be the solar-energy player that breaks new records in solar efficiency without the breaking the bank.…
