Top 4 Case studies – Missed to do Load Testing and failed miserably thereafter!

For automation of core business processes, most of the businesses go for applications. But prior to making the application available for customers, partners, stakeholders or employees, it should be understood whether the application can acceptably perform under peak load conditions. Herein lays the significance of load testing. It helps you to avoid unnecessary investments through adequate application capacity planning and tuning. Companies may experience serious setbacks without proper load testing, as these four case studies will show.

Case One

Customer service is a significant thing and almost all companies are very serious about it. Here we have a case where an organization on a regular basis indulges in evaluation of the satisfaction levels of the clients by means of different feedback mechanisms including surveys. This is followed by required enhancements to maintain high satisfaction levels. The performance and the reliability of the website play a vital role in empowering the organization to render supreme level of customer service. The web infrastructure is extended across a number of servers linked to the internet through manifold backbone providers. This particular company tried testing the performance of the distributed network by allowing people to log on randomly and provide performance report, through running test scripts. But this load testing was a failure because it did not provide a global perspective with respect to the performance. Measurement of certain specific areas only was being done.

Case Two

A particular appliance was installed by a customer on the network for load balancing a service provider’s Application Firewall. It was reported by the customer that the website stress test did not work out on enabling the Application Firewall. It was also stated by the client that the set up was working so far as the test environment is concerned. However, when the same thing was tried with the Website testing tool, it led to failure. Moreover, the firewall did not have any block logs.

Case Three

This case is about a company owning an HTML5 game development portal which ignored load testing and the web portal had to be again pulled back into beta testing. As the portal was taken out of the beta and put into the live world, several problems cropped up with the backend. As a result, the site was unable to scale at a rapid pace to keep in line with the load. It was an uncomfortable experience for the users who were keen on browsing the website and accessing the games. The organization owning the portal was not prepared enough for the real world usage, and owing to this the launch of the application was a failure.

Case Four

Here we have a company whose content delivery network enables media companies to go for large file delivery of the present age rich media Internet to the clients. Since the organization renders B2B content delivery services, keeping in line with the expectations of the media clients is a must. This can only be done through facilitating content delivery with high performance. For this, monitoring of static content of web pages as well as streaming media with respect to a global end user perspective was required. The company found it difficult to perform appropriate load testing because it did not have servers across the globe set up for testing streaming quality or http service. As a result, the organization failed to evaluate the stream quality as well as performance of its Windows Media Video and Flash Media servers.

Load and stress testing, when appropriately performed through an application’s development cycle goes a long way in reducing the count of failures affecting the application. This is a very essential aspect, especially when the application is customer facing and in involved in interaction with an external audience.

Load Testing: The Ultimate Way to Control the Queue

As the current trend goes, developers are into the habit of releasing brand new mobile apps with an aim to generate a queue for the users before a comprehensive support system can be built up for their app to fix evident issues. From the usability point of view, implementing a queue is indeed a great idea. It generates a lot of excitement within your users and also succeeds in adding that exclusivity factor to an application while the developer can deal with the scalability concerns in parallel.

However, let’s have a look at the other side of the coin. Having a queue may indeed be exciting for a few days but making users wait for the applications while the issues are being sorted out may prove to be a very risky bet for the developer or application owner, particularly when the switching cost for a user is very low. This gives a lot of scope to the impatient user to cross out your application and switch over to the subsequent one, without even getting the chance to appreciate the quality of your application.

There is off course a brilliant way to reduce this risk factor, and that’s where Load Testing comes in. It is the process of subjecting your system to high load and participation and evaluating the response. So, before making your application/app public, try to figure out the application’s performance against peak load conditions, maximum anticipated load. This will help you understand whether all the systems will synchronize in the proper manner and manage the burden of the entire user base.

Significance of Load Testing Services

The fundamental goal of Load Testing is to make sure than an application will register a good performance, in the production stage itself. With the help of load testing, you will be able to find out whether you application will cease to function or function inappropriately under heavy load and if the application is sturdy enough to fulfill the pre-determined performance levels. Moreover, load testing also gives a fair idea as to the number of users the website or application can simultaneously handle.

Some of the common performance issues that applications may face are the following:

• Issues related to software configuration (for database, web server, load balancers and so on)
• Problems arising from improper network configuration
• Imperfect software code
• Inadequate hardware assets

The sole means to identify these performance setbacks at the production stage is load testing, i.e., simulating a plethora of concurrent users. It also has a positive impact on the company’s Return on Investment by reducing the financial cost arising out of service interruptions and poor performance.

Generally speaking, this type of testing is most applicable to multiple-user systems, usually those operating on a client-server model, like web servers. But load testing can also be done for other software systems. For instance, you can always verify whether a financial package is suitable enough to process years of data and create a report accordingly or if a word processor can read an exceptionally bulky document.

Things to consider while Load Testing

• The following things need to be considered in order to ensure that your load testing is successful:
• The load goals should be clearly defined and measurable in terms of relevant parameters like requests per second, concurrent users, etc.
• Specify the goals based on real-time scenarios. For example, when you are setting the load goals in terms of number of concurrent users, specify according to the expected number within a particular time span.
• In case your application is brand new and there are no previous or specified server logs, take help from those involved in the company’s promotional activities and decide the peak.
• Set the response time based on the user acceptance quotient.

Load Testing is the ultimate means to identify the shortcomings in your website or application before launching, to ensure that even the user who is the earliest in the queue, is not facing any performance setbacks. In the long run, this will help you rise above the low ratings and unfavorable reviews, and make your application seamlessly sail through.
