About SNS Bank

SNS Bank, part of the SNS REAAL group of financial services companies, is one of the top five retail banks in the Netherlands. The company employs 3,300 people and has more than 150 offices. In recent years, SNS Bank has increasingly focused on delivering high-quality banking services via the Internet.

Challenge

SNS Bank operates hundreds of servers, both to support internal services and applications and to provide Web services to clients. The key challenge is always to provide the highest quality of service possible to internal and external users, within a cost-effective infrastructure. This requires the bank’s IT team to balance performance, availability, security and flexibility while achieving a low total cost of ownership.

When the bank was looking for a new platform for its Web-based services, flexibility and time-to-market were important considerations. SNS Bank wanted to ensure that it could quickly deploy new servers based on a standard configuration, either to add capacity to the infrastructure or to launch a new application. Equally important were security and reliability.

SUSE Solution

After formally researching several options, SNS Bank selected SUSE Linux Enterprise Server. Today, 25% of the bank’s finance infrastructure runs SUSE Linux Enterprise Server. “We use SUSE Linux Enterprise Server to run the bulk of our Web applications for customers, as well as a variety of internal bank applications,” said Emiel van Doorn, Teamleader for Java and Datacenter, SNS Bank. “The Internet service is a highly visible part of our operations, and critical to our customer relationships, which shows the trust and confidence we have in SUSE Linux Enterprise Server.”

“The reliability and stability of SUSE Linux Enterprise Server makes it a highly valuable platform to run,” said van Doorn. “As the organisation adds new servers to cope with increasing business volumes and new applications, SUSE Linux Enterprise is the standard platform used whenever possible.” On this basis, Emiel van Doorn estimates that half of the bank’s servers will run SUSE Linux Enterprise Server in the future Using a pre-built default configuration, the IT team at SNS Bank can install a new instance of SUSE Linux Enterprise Server in less than 30 minutes. The bank also has several security-oriented configuration models based on Novell® AppArmor®, which ensure that the appropriate level of security is applied.This fits perfectly with the bank’s “always-on” concept, and helps ensure that business-critical services keep running even if some nodes in the scale-out server infrastructure suffer hardware failures.

Results

The key benefits for SNS Bank of running SUSE Linux Enterprise Server are its high availability and security. High availability means that internet services are always accessible for Internet banking clients, and also that the IT team at SNS Bank can minimise the time spent resolving service outages. Clearly, security is the most crucial element in Internet banking—clients must trust that the service will not expose their personal details or put them at risk of losing money.

“Novell AppArmor makes it easy to lock down applications and create sophisticated security profiles, and we are fully confident in the security that we offer to our clients,” said van Doorn.

Having worked closely with SUSE Technical Services during the early stages of deploying SUSE Linux Enterprise Server, the bank now largely uses its own internal resources to keep the operating system running optimally. “We have seen a clear reduction in licensing and maintenance costs from switching our Java-based Web applications to SUSE Linux Enterprise Server,” said van Doorn. “It’s hard to put a figure on the increased efficiency, but it is clear that we are able to manage a large number of Linux servers with a small team and little effort!”
