Abstract: Serverless computing has transformed cloud application development by enabling organizations to build scalable, event-driven applications without managing infrastructure. AWS Lambda, a leading Function-as-a-Service (FaaS) platform, allows developers to run code in response to events while AWS handles provisioning, scaling, and execution. This paper presents best practices for event-driven applications using AWS Lambda, emphasizing performance optimization, security, cost efficiency, and observability. Key areas include cold start mitigation, concurrency management, IAM security, API Gateway integration, and compliance automation. A real-world use case demonstrates how AWS Lambda can be used for real-time compliance enforcement by leveraging AWS services such as S3, DynamoDB, SNS, and Step Functions. Intended for enterprise architects, DevOps engineers, and developers, this paper provides actionable insights to achieve higher performance, stronger security, and lower operational costs in serverless architectures.

Keywords: Serverless computing, AWS Lambda, Function-as-a-Service (FaaS), Cloud security, Compliance automation
