With business apps going beyond the corporate walls to the web, the implications on IT have increased more than ever. There is an increased pressure on enterprises to maintain application quality as it acts as a major differentiator from its competition and has a lot of bearing on customer satisfaction and user productivity. A performance-driven development life cycle helps IT shops more effectively and efficiently meet business performance requirements as customers expect applications to be fast, easy-to-use, reliable. Application performance management has become one of the key IT challenges today.

In the current market place, even a small glitch in a customer-facing application can result in its failure, ultimately resulting in revenue loss, potential loss of customers, and the organizational credibility in the market. The failure of business critical applications to work as expected can have a significant impact on the user productivity and additional costs to recover from the application failure. Poorly performing code of the internal business applications will hamper enterprise productivity, increase operational costs, result in more time for recovery, and lost time delaying product delivery.

Application performance issues can arise at any stage of the software development life cycle, and implementing performance testing right from the starting stage of the SDLC will help in rectifying the defects as early as possible and before going live. While performance testing helps enterprises to identify the root cause of performance issues, enterprises must make sure to set clearly defined expectations to measure the performance of an application. Applications might work well before going live, but they might fall flat in real time when there would be huge peaks in demands in the future. A key requirement for applications today is that they should perform acceptably even under the heavy-load conditions as increased traffic can impact the application architecture’s performance. Load testing helps enterprises to determine the application’s capacity to handle the load and provides information about the number of users an application can handle.

Knowing the breaking point of an application to predict the amount of volume it can handle and whether it will be able to meet the future demand is also an important characteristic in measuring the performance of an application. Stress testing evaluates the capability of a system or application up to saturation or breaking point. In a similar way, there are several tests that provide insights into different attributes of an application, which will help in launching an application that performs as expected.

But, often enterprises skimp on areas like performance testing due to the budgetary constraints of building test labs that are replica of the production environment. Enterprises must realize that firefighting wastes time, money, and good will. Outsourcing performance testing tasks to independent testing specialists is one of the best options for them. It will help enterprises to take corrective measures to rectify performance issues as early as possible by using advanced testing services, skilled resources, and implementing the suitable tools based on the organizational requirements.
