As cloud computing continues to evolve, serverless architecture has emerged as a critical solution for building scalable applications. Amazon Web Services (AWS) Lambda allows developers to run code without managing servers, enabling a focus on code rather than infrastructure. To streamline development and enforce best practices, AWS introduced Lambda Powertools—a set of utilities designed to simplify the building of serverless applications.
