In 2019, I worked at an investment bank in the city of São Paulo. Every day, our systems processed millionaire transactions, and our general motto was "stability and security."

One of the precautions we took was to prevent DDoS (Denial of Service) attacks. Although cloud platforms guarantee they will not have DDoS problems because their systems are robust and scalable to handle a large number of requests (with a large amount of money), we did not want the bank to spend an absurd amount of money if they suffered such an attack.
