[UNI_MELB_08] Traditional business applications have always been very complicated and expensive. The amount and variety of hardware and software required to run them are daunting. We need a whole team of experts to install, configure, test, run, secure, and update them.

Small and mid-sized businesses don’t stand a chance. In today’s era with cloud computing, you eliminate those headaches because you’re not managing hardware and software that’s the responsibility of an experienced vendor like salesforce.com. The shared infrastructure means it works like a utility: You only pay for what you need, upgrades are automatic, and scaling up or down is easy. In this paper we analyze several aspect and impact of software engineering parameter like design, modularity, testing etc.
