Using Software-as-a-Service (SaaS), software resides on servers not on user computers. Service Oriented Architecture (SOA) provides the ability to divide an application into parts known as services. This allows enhanced support for distribution, code re-use and code sharing. Combining these ideas, applications can be dynamically composed from components stored at convenient locations in a wide-area network. This benefits users since software installation and upgrades are unnecessary and is also suited to personal devices that may have limited resources (e.g. disk space) to support conventional installed software. I have designed, prototyped, and evaluated component-placement and location algorithms for a system that combines ideas from SaaS and SOA to support on-demand composition of applications that run on user devices from storage sites in the network. These algorithms support mobility and are scalable and reliable. I have implemented a Java prototype and a simulation system that I used to assess my system’s behaviour.
