It is very critical evaluate the application behavior under a specific load condition before releasing it to public. Imagine a user tried to access your news webpage taking more than 30 sec. User would prefer to visit other website which gives him faster response and save time. We are in competition world and person/object/application who performs better would win the race and gain the people attraction.

There are several tools exist in the market to perform load testing. However, it is always difficult to choose which one best suites my needs. Most of the small and mid size product owners would prefer to skip from performance testing or limit performance testing. These are several reasons and below are top 3 reasons :

1. Need to invest log of money to procure the a tool license.
2. Procuring/Leasing the hardware recourses need lot of investment.
3. Project release deadlines.

Earlier, there was no easy solution for all these 3 problem. However, with the help of cloud and SaaS we have very easy solutions.
