Lately, I've heard a lot about cloud computing. It starts with fast networks and technologies such as Mashups and REST interface. A mashup allows you to take information and processing coming from different sources and put them together to provide a new application and new insights based on the data manipulation.
REST (REpresentational State Transfer) is a way to access data, possibly through a web service, using the HTTP protocol (Web server protocol). This makes it simpler than using the SOA SOAP interface.
