The Challenge
The bank, one of the 20 largest regional banks in the world, was facing new competition from non-traditional banks with flexible infrastructure and agile development. Despite recent IT systems centralization of all regional subsidiaries onto a single platform, and reliability improvements, the bank’s leaders called for faster application development and innovation. Each application required a unique development and testing environment, making the bank’s infrastructure complex and diverse. The bank’s engineers had to wait days or weeks for new systems to be provisioned, during which time, provisioning visibility remained low. Once deployed, engineers and IT had poor visibility of platform utilization. These inefficiencies drove new server purchases to 500 units per year, constraining other IT investment. The bank needed a new environment to minimize the time and effort it took to build platforms, ideally with self-service and visibility for developers.
About The Customer
The customer is one of the 20 largest regional banks in the world, with over 300,000 employees and 100 million customers. The bank serves more than 20 countries across two continents and operates more than 10,000 branches and 80,000 ATMs. Despite its size, the bank remains responsive and stays ahead of market trends with a strong focus on digital transformation. Extensive online and mobile banking investments have produced over 30 million consumer and corporate users. The bank has outperformed industry rivals, however, it faces new competition from non-traditional banks with flexible infrastructure and agile development.
The Solution
The bank’s IT infrastructure team began a broad search for a new, flexible private cloud platform. They decided to use OpenStack as it could provision and manage their wide range of Dev/Test configurations. Mirantis was selected to demonstrate its technology stack with a simple user interface to provision diverse virtualized environments. Mirantis designed the bank’s architecture and deployed a small-scale version of the new platform by the end of 2015. The new platform used Mirantis OpenStack distribution as well as the Fuel cloud provisioning and management tool included in the distribution. Additionally, the Horizon user interface provides a web based dashboard to provision OpenStack services such as Nova compute, Swift storage, and Keystone identity services. And custom Fuel plug-ins integrate the new platform to existing IT environments including Active Directory and EMC, Hitachi, and Huawei SAN storage.
Operational Impact
  • The bank’s OpenStack instance of 160 nodes is now deployed in a new European data center. Already, 100 developers access the platform and are benefiting from its one-click, self service provisioning and usage visibility.
  • One group of developers has already started re-coding the core banking system in a cloud-native format. Others are building new cloud ready applications such as online banking user interfaces.
  • The infrastructure group has been able to closely monitor platform use and reallocate resources that are checked out but sit idle. As a result of this success, the bank has plans in place to use OpenStack, not just for Dev/Test, but also for many production environments. With OpenStack, the bank can scale the platform and still efficiently manage it with a small operations team.
Quantitative Benefit
  • Faster and self-service platform provisioning; from weeks to hours
  • Accelerated application development and deployment
  • Improved infrastructure utilization and efficiency
