Working for the FITT project, which consist of migration from several datacenters into one, more then 400 applications will be migrated.

Study researchers found three-quarters (77%) of mobile users are concerned about app performance before they buy. (Kristina Knight)

However mobile devices typically have: slower CPUs, smaller screens, and less memory than the typical desktop PC.

Connections can come from cell phones, tablets, and various other devices with widely different capabilities. Then there is the diverse and growing range of platforms used in the mobile world, including Android, BlackBerry, iPhone, and Microsoft Windows Phone. To complicate matters further, there are many existing versions of platforms in use today.

There aren’t enough hours in the day to test on every device….

Best Practice Guidelines for Developing Quality Mobile Apps

In house,Need to buy devices all the time / For older models secondhand .In controll of network and installed apps.Good for Performance testing

In the cloud,

Pay per useGood for functional testingNewest devices availableNetwork control ?Installed apps ?Measuring recources ?
