The interest on Rich Services Cloud Applications is growing fast. Users want responsive and immersive interactions from any locations. Nowadays, you cannot think about a business application without mobility in mind. However, you cannot avoid creating a rich user experience (UX) in mobile devices whilst accessing services on the cloud. If you want to offer a really nice experience, you’ll have to use parallel programming skills everywhere.

Most modern Web pages run scripts. So far, there are many limitations to allow these scripts to take advantage of multicore microprocessors. However, Web Workers is a draft specification that defines an API to allow Web application authors to spawn background workers running scripts in parallel.
