Many large enterprises have successfully implemented DevOps practices to improve software development and delivery processes, despite challenges such as legacy assets and rigid organizational structures. One example is Watchful Bank, which underwent a digital transformation that included reorganizing its teams into cross-functional units, implementing containerization for rapid deployment, automating testing, and using feature flags to manage risks associated with legacy systems. As a result, the bank achieved faster release cycles and improved quality while minimizing disruptions to customer experience and back-office functions.
