The primary U.S. banking subsidiary of Citigroup, a financial services multinational corporation, will work with the search engine giant so they can "modernise" things going forwards.

Citi technology and business enablement head Tim Ryan said: “Citi is on a mission to modernise our infrastructure and increase our safety and soundness so that our businesses can continue to serve our clients with speed and agility.

“Leveraging Google Cloud opens up a whole new frontier for us in how we can run applications with faster and more comprehensive outputs, and provide our colleagues with the tools they need to deliver for our clients.”

The upgrade will enable Citi to offer better digital products, streamline employee workflows, and leverage high-performance computing (HPC) and analytics platforms, according to Google Cloud.

Google Cloud CEO Thomas Kurian said: “Our strategic partnership with Citi to continue to modernise its technology infrastructure and drive enterprise-wide innovation underscores Google Cloud’s commitment to helping the financial services industry transform with cloud and AI technology.

“By combining Citi’s deep banking and customer experience expertise with Google Cloud’s leading cloud and AI capabilities, we can deliver significant benefits to Citi’s clients and employees.”
