With the tens of thousands of lines of code that go into modern software and the inconsistencies that can sometimes occur when programs are compiled to machine language, it can be very hard to guarantee the integrity of almost any software. For organizations that rely on the quality, reliability, and security of their software, no hole can go unpatched. To achieve this, rigorous software testing is an absolute necessity.
One of the most difficult situations any piece of software can undergo is extreme load. With the ubiquity of the Internet and sheer computing capacity computers have today, situations of extreme load are no longer very uncommon. Denial-of-service attacks happen almost on a day-to-day basis, and software bottlenecks can occur when poorly optimized code is fed so much data too quickly.
