As business apps move to the web outside of the corporate walls, the implications for IT are growing more than ever. Businesses are increasingly under pressure to maintain application quality as it sets itself apart from the competition and has a significant impact on customer satisfaction and user productivity. A performance-oriented development cycle helps IT stores meet business performance demands more effectively and efficiently, as customers expect applications to be fast, easy to use and reliable. Application performance management has become one of the most important IT challenges today.
In today’s market, even a minor glitch in a customer-facing application can result in its failure, ultimately resulting in loss of revenue, potential loss of customers, and the credibility of the organization in the market. If business-critical applications fail to work as expected, it can have a significant impact on user productivity and additional costs to recover from the application error. Poorly performing internal business application code will hamper the productivity of the enterprise, increase operating costs, result in more recovery time and delayed product delivery.
Application performance issues can arise at any stage of the software development lifecycle, and implementing performance testing from the beginning of the SDLC will help resolve the failures as early as possible and before it goes live. While performance testing helps enterprises identify the root cause of performance issues, enterprises should ensure that they set clearly defined expectations to measure the performance of an application. Applications may work well before going live, but they could go down in real time if there were massive spikes in demand in the future. An important requirement for today’s applications is that they must perform acceptably even under heavy load, as more traffic can affect the performance of the application architecture. Load testing helps companies to determine to what extent the application can handle the load and provides information about the number of users that an application can handle.
Knowing an application’s breakpoint to predict how much volume it can handle and whether it will be able to meet future demand is also an important feature in measuring application performance. Stress testing assesses the capacity of a system or application to saturation or breakpoint. In a similar way, there are several tests that provide insight into different attributes of an application, helping to start an application that is performing as expected.
But often companies are cutting back in areas like performance testing because of the budget constraints of building test labs that replicate the production environment. Companies need to realize that firefighting is a waste of time, money and goodwill. Outsourcing performance testing tasks to independent testing specialists is one of the best options for them. It will help companies take corrective action to resolve performance issues as early as possible by using advanced testing services, competent resources and implementing appropriate tools based on organizational requirements.
