I work for a startup bank in the UK (Mondo). Our Go microservices architecture allows us to maintain velocity whilst staying secure. The core banking services that actually move money around are isolated from the more "fluffy" customer facing ones that we want to be able to push updates to several times a day. We have to have incredibly rigorous procedures for updating services that control money, if we had a monolithic architecture then these procedures would have to be used even if the change was simply cosmetic.
