What are the 3 components of AWS Lambda?

AWS Lambda consists of three main components that enable serverless execution: Function, Event Source, and Execution Environment.

1. Function – This is the actual code that runs in response to an event. It can be written in Python, Node.js, Java, or other supported languages.

2. Event Source – Lambda triggers functions based on events from sources like S3, API Gateway, DynamoDB, or CloudWatch.

3. Execution Environment – AWS provides a managed runtime for executing functions, ensuring automatic scaling and security.

These components allow businesses to run scalable, event-driven applications without managing infrastructure.

Key takeaways:

• Function: The code executed by AWS Lambda.

• Event Source: The AWS service that triggers Lambda functions.

• Execution Environment: The runtime that manages scaling and security.

• AWS Lambda enables serverless computing for real-time applications.
