IT service provider ensures scalability of banking apps
Digitization increases demand for high performance banking systems
One focus of the service offering is ‘Centralized Online Real-time Exchange Banking Systems‘ (CBS). These allow finance companies to make information about transactions available in a decentralized form for real-time processing. Swisscom was looking for an IT monitoring solution that would allow CBS and other IT assets to be monitored. The aim was to find a solution that could replace several other tools and was suitable for use in the managed service environment. This includes a secure separation of customer information and comprehensive scalability if, for example, a large number of new assets have to be included in the monitoring process within a short time frame.
At the same time, Swisscom Banking is bound by a wide range of regulations. For example, for security reasons, a CBS may not be operated as a cloud platform. It should therefore also be possible to set up monitoring on-premises. In addition, access from outside Swiss territory is not
permitted under any circumstances, as no data may leave the country.
At the heart of the monitoring are the computer centers which Swisscom Banking operates as the basis for its Managed IT Services. The hardware is based on mainframes running AIX or Solaris as operating systems. The MSP can monitor all systems via the supplied Checkmk agents.
Swisscom customers usually book monthly adaptable infrastructure plans with targets for CPU, RAM, and hard disk space. According to these bookings, Swisscom Banking partitions an LPAR segment in their computer center and allocates the agreed resources to the customer. The IT team also creates a Checkmk remote site in the customer’s environment. The IT team then manages this via a Checkmk central site, which it sets up in the same computer center.
All Checkmk instances run on high availability Red Hat server clusters (active/passive). Swisscom Banking’s IT specialists then set up the desired servers and systems in the customer segments. CBS usually rely on large Oracle databases. The monitoring experts at Swisscom Banking wrote their own checks for the Checkmk Oracle plug-in so as to optimize data evaluation.
