Case Study: Preventing Site Outages During the Holiday Rush

Performance testing in advance of trigger points can save your customer relations

This time of year, many companies are now in the process of conducting web load testing in advance of the holidays. In this article, you'll learn details on how a large online retailer conducted web load testing in advance of the holiday spike in traffic - and they're moving into the holiday season more confidently than ever.

Why This ‘Retailer' Came to Compuware
As a leading retailer of personalized gifts, it needed to ensure that its website would be ready for the 2012 holidays. Despite load testing its site last year with a different vendor, The Retailer experienced several outages during peak traffic, costing them significant revenue. Great customer experiences and relationships are very important to this Retailer - both in-store and online. However, as a result of the site outages, customer relationships were impacted both online and in its brick and mortar locations.

In order to provide its customers with great experiences, and protect its reputation, the Retailer's online store has to not only provide a great shopping experience, but also withstand the traffic spikes caused by seasonal upswings, events and promotions. Since performance directly impacts the business, much is riding on the performance of its website during the critical holiday season.

Understandably, leery of promises about ensuring scalability after last years' experience, the Retailer contacted Compuware to engage services to deploy its Gomez 360o Web Load Testing solution which was selected based on three key factors:

  • Enough Load could be generated from enough locations to thoroughly stress its system;
  • Real browser technology for the agents would ensure the most realistic testing and problem identification; and
  • The diagnostic capabilities of dynaTrace's PurePath technology would show the root cause of any problem

The Retailer utilized Compuware Professional services in order to have an independent third-party that would help them design a test plan to re-create issues, not just prove that the system worked.

With Gomez 360o Web Load Testing, each transaction performed during load testing was traced. In addition, all of the diagnostic information correlated into load test reports so there was complete visibility into how applications behaved under load. Armed with this information, the Retailer identified any problems in both proprietary code as well as third-party code.

Retailer's Plan of Attack

  • Test from the end-user perspective using last mile, real browsers and less than ideal Internet speeds.
  • Test the production system during least use in the middle of the night giving a four hour test window with normal peaks lasting approximately 10 hours
  • Calculate load volume based on highest hourly historical activity - then multiply the test window by 2.5 to obtain a 10 hour peak.

Results
The Retailer's site could handle the peak load but not for the allotted four hours. The analysis revealed multiple root causes of instability including:

  • Load balancer issues
  • Gateway errors
  • SQL issues
  • JVM Issues

Reconfiguring the load balancer solved the site crashes while code changes optimized certain queries. JVM optimization was taken care of by forcing garbage collection more frequently.

The quality and speed of the Retailer's website is now on par to provide exceptional user experiences for their e-commerce customers, aligning it with the caliber of in-store service that is expected. The Retailer was also able to reduce testing iterations and cycle time with proactive problem resolution and prevention and validate that the website architecture is performing properly for maximum scalability under peak load.

Actionable data is easily provided to their outsourced development vendor. This not only gives the vendor a deep, code level view in order to quickly fix and optimize the application code, but relations between the vendor and the retailer are greatly improved since the data eliminates finger pointing.

The Retailer is confident it will not have a repeat of last year's outages and its site will perform optimally during peak traffic periods throughout the holiday season.

There is no doubt that Big Data is here and getting bigger every day. Building a Big Data infrastructure today is no easy task. There are an enormous number of choices for database engines and technologies. To make things even more challenging, requirements are getting more sophisticated, and the standard paradigm of supporting historical analytics queries is often just one facet of what is needed. As Big Data growth continues, organizations are demanding real-time access to data, allowing immediate and actionable interpretation of events as they happen. Another aspect concerns how to deliver ...
WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment.

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
As we approach the next @ThingsExpo, to be held June 9-11 at the Javits Center in New York, my thoughts naturally turn to the Internet of Things. The IoT is a leviathan—in the best possible sense of the term—that will sweep up most everything in the ocean of data and technology being created today and tomorrow. But rather than try to grasp all of its possible uses, for today I'm looking at “just” the Industrial Internet part. I just read a long paper co-authored by Tim Berners-Lee about the possibility of describing a “web science,” that is, discipline that combines the study involved ...
