Cloud based core banking: Is it possible?

Benefits of migrating core banking to cloud

Financial institutions can realize long-term benefits by migrating their core banking infrastructure to the cloud.

Cloud computing for financial services

Over the years, cloud computing has transitioned into mainstream technology from bleeding edge. In 2017, 74 percent of financial services companies* in the industry, have already adopted some extent of hybrid/public cloud architecture. However, most financial institutions have typically taken a risk-based approach to adopting the cloud, beginning with proofs of concepts, Software as a Service solutions, new native cloud application development, and front-office functions but not necessarily core functionality. Hence the next question is, has the time come to move core processing to the cloud? And if so, how fast should businesses adopt and transform to use the cloud?

This thoughtware summarizes the immediate and long-term benefits for financial institutions when migrating their core banking infrastructure to cloud, while enlisting the risks and challenges associated. Some of them include:

Rewards

  • Infrastructure savings: Cloud computing can cut out the high cost of infrastructure for companies, eliminating the need to maintain their own data centers.
  • On-demand scaling and agility: Cloud-based services are agile and easy to scale up (or down) on-demand, adhering to organizational computing needs.
  • Security & availability: The public cloud excels in two critical security areas. Information resiliency and privacy.

Risks

  • Limited understanding of mainframe applications: Cloud migration of technical assets such as legacy platforms, can pose a risk if due diligence is not performed to ensure that all necessary dependencies are preserved and functionality tested.
  • Preserving upstream/downstream dependencies: Depending on where a particular application falls within the data chain, upstream or downstream data dependencies must be accounted for when migrating said application to the cloud.
  • Untangling data transformations from third-party sources: Core banking applications can rely on data from third-party systems. When transmitted into the enterprise, such data often goes through various layers of transformation to ensure consumption by a target application.

Leading the core banking transformation

The time has come to move core bank processing to the cloud, and it should be on the minds of all banking executives. Ultimately, mainframe-based applications that support core banking will need a target disposition assigned to them; this report outlines the dispositions that lay out the migration methodology.

The approach detailed in this paper lays out an achievable, calculated approach to moving core banking to the cloud while mitigating risk throughout the move. Cloud has the scale, security, availability, and meets the regulatory needs to have critical core banking workload migrated. Banks can realize quick wins while simultaneously learning—as a cohesive organization—on how they need to adapt to a post-mainframe world.
