When a company experiences a surge in document volume but lacks the computing power needed to process them efficiently, what's the solution? Volkswagen Financial Services AG (VWFS) recently faced this challenge. For years, they relied on a central Rendition Service (zRS) consisting of an SAP front-end and server farm (worker) to convert documents. Specialist applications electronically send data to the zRS, which prepares finished documents as AFP, PDF/A, and TIFF files and sends them back to the specialist applications.
However, the zRS system is built on a 32-bit architecture, which quickly reaches its capacity limits, making it difficult to handle increasing document volumes without expanding the server farm. Scaling up the hardware is a costly and time-consuming process, and maintaining this unique system is an arduous task.
Security is another crucial concern for VWFS. While the server farm can compensate for the failure of a worker and ensure uninterrupted processing, the SAP front end is a single point of failure. If it fails, the entire zRS comes to a halt, causing significant disruption to operations.
Over the last four years, VWFS has seen a visible increase in the volume of documents to be processed, with 14 million conversions currently being performed and the trend continuing to rise. According to Gottfried Busch, who is responsible for IT and processes at Volkswagen Financial Services Digital Solutions GmbH, the zRS system in place at the time and its architecture were unable to keep up with this demand, resulting in decreased performance. This issue was further complicated by the introduction of new document-generating systems, which led to a growing variety of formats, and the increasing demands for quality and speed in customer communication. Initially, VWFS tried to address the problem by enlarging the server farm, but soon realized that this approach was not sustainable in the long run.
To address the performance and scalability issues of the previous system, VWFS decided to switch to the master node architecture of DocBridge® Mill Plus. This is a flexible software that can analyze, split, modify, and convert documents of any type, size, and format. The new zRS is now composed of two independent and self-contained master node chains, each capable of handling the entire rendering workload at VWFS. The master modules now control the system instead of SAP, ensuring very high availability at all times (7x24 and 99.5%).
If a master node fails, daily operations still continue, thanks to this redundancy. Moreover, the system can easily expand by adding further virtual nodes, providing arbitrary scalability for future growth. The new zRS can now process more than 14 million documents with just one master node server, making it well-equipped to handle the increasing volume of data in communications in the future.
Mr. Busch, who is responsible for IT and processes at Volkswagen Financial Services Digital Solutions GmbH, stated that the new DocBridge® Mill Plus system offers flexibility that was not possible with the previous server farm architecture. The ability to easily adjust capacities to prevent processing speed from being affected even when volumes increase or fluctuate is a significant advantage of the new system. When comparing the current and previous systems, taking into account the increased volumes, it can be said that the performance has multiplied many times over. In the past, downstream applications were slowed down because the legacy system (32-bit) repeatedly reached its limits and throttled performance.
However, the new system can render data up to a size of 20 MB in real-time and transfer it to downstream applications without any delays. Additionally, the system's 64-bit architecture provides a performance improvement of ten times within a two-minute time window, without affecting downstream systems. According to Busch, the specialist departments were fully supportive of the conversion project from the start because of the ability to process larger files much faster than before.
It's great to see how the new zRS with the master node architecture of DocBridge® Mill Plus has not only improved the data throughput and processing speed but also reduced the costs for dark processing. The fact that the new system enables high-performance dark processing has opened up new and more efficient possibilities in data processing processes for certain specialist applications.
Moreover, the employees quickly realized the potential of the new system and worked with Compart to develop it with many technical refinements and put it into production within a very short time. Finally, it's worth mentioning that Compart also offers a cloud-enabled technological platform for rendering called DocBridge® Conversion Hub.
