Cloud computing adoption has increased in the banking and financial sector over the last five years. It offers lower upfront IT costs and quicker implementation compared to traditional systems. Both large and small banks are investing in cloud technologies, with smaller banks finding cloud solutions to be cost-effective. Public cloud provides agility and innovation, though many large banks prefer private cloud for its security and control. Cloud adoption varies by region but is growing in popularity globally. Vendors must understand customer needs to offer the right cloud solutions and ensure ongoing support for customer success.
