What is a common use of AWS Lambda?

• A. For running servers continuously
• B. For executing code in response to events
• C. For managing virtual networks
• D. For hosting static websites

Answer: (B)

AWS Lambda is a serverless computing service that allows you to execute code in response to specific events without the need to manage server infrastructure. This event-driven architecture means that whenever an event occurs—such as changes in data in an Amazon S3 bucket, updates to a DynamoDB table, or even requests from an API Gateway—Lambda can automatically run the corresponding code without any ongoing management of servers or resources. This approach is highly scalable and allows developers to focus on writing code that responds to events rather than worrying about the underlying infrastructure. Using AWS Lambda provides significant benefits, including cost efficiency, since you only pay for the compute time used while executing the code and not for idle server time. It also simplifies the development process by enabling the integration of different AWS services that can trigger the execution of the business logic encapsulated in Lambda functions. This makes Lambda a preferable choice for various applications, including chatbots, data processing, and back-end services for web and mobile applications.
