Top Stories by Eric Farrar

Up until recently, Web applications were "connected-only" applications. Users could only use the application by connecting to the central server and all data access was done in a single place. For many years, people accepted that was the limitation of Web applications. But it isn't a limitation any longer. Over the past year a number of technologies have come along such as Adobe AIR and Google Gears that allow offline access to the data and the application.

Isolated Customer Data: A Better Fit for the Cloud?

For all that global business has embraced cloud computing - welcoming its low cost, low barrier to entry and reduced IT burden - not everything about this architectural sea change is working out perfectly. Limitations in security and customization are a growing source of discontent for many current and prospective cloud customers. The need to serve similar data for many customers usually shows up in hosted environments.
