Like most other global banks, Barclays has faced challenges in adapting to modern digital banking. Most banks still operate on mainframes, which means that there is a single point of failure and any sort of glitch or outage can leave customers without access to their services for hours, if not days.
Last year Barclays made the headlines with two outages, which caused its customers problems. However, Barclays is using NoSQL database provider MongoDB to accelerate its digital banking capabilities, with future plans to even let customers carry out some of their banking transactions on Facebook, under the new PSD2 EU directive.
