Service-oriented software today: Delivery and mobility rule

The cutting edge in application development has moved on from ''captive'' in-house applications to Web applications and mobile applications,'s Jack Vaughan tells James Denman in a brief discussion on trends in Service-oriented architecture, Web services, and application development.

Vaughan cited the words of Rashid Khan, who contributed to a recent article on Khan said mobile applications require developers to change their style in order to cater to mobile devices. The devices are smaller and have systems constraints around memory, storage, screen size and other factors. Also, mobile users are constantly on the go and have less patience to sift through extra functionality. As a result, we're seeing a trend of developers chunking services in new ways so that they can present more concise mobile applications for the mobile workforce.

Also, Vaughan cited another article from the pages of with Andi Gutman of Zend. From Gutman we learned that PHP has come into the enterprise. Business people see the success of commercial applications like Netflix and FaceBook that are flexible and constantly evolving and they expect that sort of flexibility within the enterprise. This is an area where PHP has some ease-of-use advantages over Java.

Finally, Vaughan discussed the Forrester Application Development & Delivery Forum 2011. According to Mike Gilpin, who had a hand in organizing the event, there may heretofore have been extra focus on development and not enough focus on delivery. This is a problem Forrester aims to correct at this year's conference. Gilpin says that application developers are now closer to the customers than they used to be, and that it has become necessary to develop client-facing applications in an agile, iterative fashion.
