The Problem

After opening its doors in 2017, the Elbphilharmonie began to experience unprecedented demand for tickets to shows. This level of demand lead to unacceptable latency issues being experienced by customers accessing the ticket portal, resulting in ticketing issues and a negative user experience.

Why Kemp

To improve the customer experience, the Elbphilharmonie’s hosting provider, Medialine AG was tasked with finding a best in class load balancing solution that was easy to use, could be deployed quickly and keep latency to a minimum. After conducting a review of the leading load balancing solutions, Kemp came out on top.

The Solution

Elbphilharmonie deployed Kemp VLMs configured in a HA pair to intelligently manage client connections to their ticket portal, providing a rapid response time and ensuring continuous uptime during peaks and troughs of usage. Once implemented, the VLM’s provided a quick and seamless user experience for customers purchasing tickets.

The Challenge

The Elbphilharmonie, a state of the art concert hall and iconic landmark located in Hamburg, Germany, was completed towards the end of 2016. It had been planned with the aim of creating a new landmark for the city and a “concert house for all to enjoy”. The 360-foot building comprises a large concert hall with 2,100 seats and a smaller hall with 550 seats, as well as a hotel and 45 residential units. The Elbphilharmonie’s sophisticated program includes classical concerts as well as festivals, presentations, and workshops for all ages.

Since its grand opening in January 2017, the concert hall has enjoyed unpreceded attendance levels at shows and concerts taking place in its state of the art facilities, welcoming over 480,000 guests in its first season. The upward curve has continued into the second season, with over 850,000 tickets expected to be sold and further plans announced to increase the number of shows on offer throughout the remainder of the year.

While the success of the Elbhilharmonie since its opening day has brought many benefits to the city of Hamburg, from a technology perspective, it has also provided many challenges. One such challenge is to provide a smooth user experience for guests when booking tickets online during periods of high demand.

Tasked with solving this challenge was Medialine AG, a full-service IT&C systems house responsible for hosting the Elbhilharmonie’s servers and applications in its Frankfurt based data center, including the ticketing booking system, the website, integrated checkout and website based on NGINX. “As soon as advance ticket sales for Elbphilharmonie events begin, traffic on the website and the associated ticket shop sky-rockets. On some days, we have received over 30,000 enquiries at the same time,” explains Knut Kopf, Sales Manager at Medialine.

To meet its SLA of not losing a single event-related enquiry from a potential customer, Medialine knew they required an intelligent load balancing solution to provide a seamless and non-disruptive ticketing experience for online customers.

 
“The importance of both the website and the online ticket shop being available around the clock and working reliably should not be underestimated. A server failure could do considerable damage to the image of such a renowned concert house. We therefore, began to look for load balancers which can process enquiries at peak times and at a reasonable cost.”

The Solution

As Medialine AG began their search for a load balancing solution, they came across Kemp. They were particularly impressed with the fact that Kemp was a specialist provider of application delivery controllers and could offer a range of advanced virtual ADCs, at a price point that represented a good return on investment in comparison to other leading vendors. In early 2017, Medialine decided to order two Virtual LoadMaster 5000s, capable of individually delivering 5000 Mbps of throughput and 10,000 SSL TPS, an optimal solution for providing high availability in demanding enterprise application and e-commerce web deployments.

Kemp VLMs intelligently direct requests for client access automatically to the virtual servers in order to deliver high performance based on factors such as simultaneous connections, CPU load, and memory usage to avoid "bottlenecks" in the network. If then a server or application does not respond, the user is automatically redirected to another server that is up and running.

The Implementation

The VLMs were deployed within Medialine's infrastructure, consisting of 3 physical servers, all of which had been virtualized with Hyper-V. Running on the physical servers and a redundant storage environment were 80 virtual machines.

The VLMs were configured in a HA pair to manage client connections to the business critical applications, ensuring continuous uptime during peaks and troughs of usage. Thanks to the Kemp load balancers, the critical applications could be expanded or scaled with additional virtual machines whenever needed so that the required performance levels could be guaranteed at all times. “The load distribution among the virtual servers fully meets our specifications in terms of functionality and performance. We have been able to get spontaneous configuration adjustments quickly whenever necessary to adapt the overall system to unforeseen load situations,” said Hanns-Wolfgang Trippe, project manager at the Elbphilharmonie.

The End Result

Since deploying the pair of VLMs, they have done exactly what has been expected, distributing peak usage enquiries among the available scaled virtual servers of the website, ticketing system, and integrated checkout, thus ensuring high availability.

With the pair of Kemp VLMs sitting at the heart of Medialine’s Hyper-V environment, they have been able to provide a seamless user experience for online ticket buyers and with no adverse disruption to ticket sales during peak demand. The Elbphilharmonie’s goal of not losing a single event-related enquiry from a potential customer has therefore been achieved. “We are very satisfied with how the project progressed. Kemp’s German-language technical support assisted us splendidly, the price-performance ratio is outstanding, and the systems are running reliably. In addition, the installation effort is minimal,” Kopf summarizes.

Due to the positive end result, Medialine intends to extend its cooperation with Kemp in the future, especially when it comes to larger customer environments where the load balancers can realize their full potential.
