Published on 17 Oct 2013

At FNB, we don't just think of IBM zEnterprise as the platform for our core banking software; rather, it hosts the core functional layers that allow the channels to create value for our customers

First National Bank (FNB) is one of the four divisions of FirstRand Bank Limited within the FirstRand Group, one of the largest financial institutions in South Africa. FNB provides retail, wealth, business, commercial and corporate banking services to more than eight million customers. It also gives its customers access to other services provided by its parent group, including asset finance insurance, and investment fund management

Business need
The ubiquity and convenience of cellphone and tablets as computing devices represented a clear growth opportunity for FNB; in South Africa, more people have cellphones and smart mobile devices than bank accounts. FNB wanted to launch a reliable, secure and highly responsive mobile channel before its competitors, and looked for a platform that would enable very short time-to-market.

FNB integrated a new Java-based mobile front-end directly with tried-and-trusted business logic and core banking services running on IBM® Information Management System (IMS™) on an IBM zEnterprise® EC12 server. IBM IMS Enterprise Suite Connect APIs for Java and C and IBM IMS Enterprise Suite SOAP Gateway manage links between the channel applications and core functionality and data on the mainframe.

Rapid deployment enabled FNB to gain first-mover advantage in the market, gaining the number one spot for mobile banking. Ultra-low average end-to-end response times of 30 milliseconds ensure snappy performance for mobile banking users. Fast, secure and reliable mobile banking generates more business for FNB and reduces its average cost per transaction.
