Serverless architecture serves as a cloud computing model that allows developers to build and run applications without managing the underlying server infrastructure. In serverless models, the cloud provider handles server management, scaling, and resource allocation, which significantly simplifies development and reduces the operational burden on developers.
AWS Lambda is the correct answer because it is an example of a serverless computing service. With AWS Lambda, users can execute code in response to events without needing to provision or manage servers. This service automatically scales in response to incoming traffic, allowing developers to focus on writing the application logic rather than worrying about server capacity or management tasks.
In contrast, AWS EC2 (Elastic Compute Cloud) is a service that provides virtual servers for computing, requiring users to manage instances and handle scaling manually. AWS S3 (Simple Storage Service) is a storage service that allows for file storage and retrieval but does not involve running code. AWS RDS (Relational Database Service) is a managed database service that requires database management actions and resources, which also does not align with the concept of serverless as it still requires users to manage instances and configurations.
By focusing on event-driven execution without the complexity of handling server infrastructure, AWS Lambda embodies the principles of serverless architecture, making it the right
