Introducing LoadRunner

Over the last 20 years, companies have turned to software as a means of automating work. Software applications have been used to drive huge efficiency and productivity gains and to provide a new medium for
collaboration and information sharing in a global economy. Software applications have, in fact, become the primary channel both for business critical information sharing and transaction processing of all kinds. Today,
software applications from e-mail to CRM to Transaction Processing are the business.
While software development technologies have changed and matured tremendously in this time period, the omplexity of modern applications has exploded. Applications may utilize tens and hundreds of components to do work once done with paper or by-hand. There is a direct correlation between the degree of application complexity and the number of potential points of failure in a business process. This makes it increasingly difficult to isolate the root cause of a problem.
Moreover, software applications aren’t like cars. They don’t have permanent parts that are replaced only when they wear out. Whether to deliver competitive advantage or to respond to changes in business conditions, software applications change weekly, monthly, and yearly. This stream of change introduces yet another set of risks that companies have to manage.
The incredible pace of change and the explosion of software complexity introduce tremendous risk into the software development process. Rigorous performance testing is the most common strategy to both quantify and reduce this risk to a business. Automated load testing with HP LoadRunner is an essential part of the application deployment process.
