Digital transformation and the introduction of legislation aimed at meeting cybersecurity requirements is forcing businesses to go through a process of modernisation that involves a move towards open architecture models. In particular, with the introduction of the revised Payment Services Directive (PSD2), the most recent directive (no. 2366) issued by the European Parliament and the EU Council, banks are now also obliged to update their IT ecosystems in ways that facilitate new operational models.
The existing IT architectures used by banks already allow services to be offered based on the use and consumption of existing channels (e.g. Internet and mobile banking). These rely on SOA service layers and integration with legacy systems. However, there is a clear gap to be filled in terms of providing such services publicly and securely.
