Serverless architecture is a way of building and running applications without the need to manage infrastructure. You write your code, and the cloud provider handles the rest - provisioning, scaling, and maintenance. AWS offers various serverless services, with AWS Lambda being one of the most prominent.

It's a little more code, but it's 1000% safer, and even in the worst case (the row does not already exist), it performs the same as the anti-pattern.
