Likewise, what is an event in AWS Lambda?

AWS Lambda integrates with other AWS services to invoke functions. Each service that integrates with Lambda sends data to your function in JSON as an event. The structure of the event document is different for each event type, and contains data about the resource or request that triggered the function.

Beside above, what is Lambda event in Python? Aws Lambda passes any event data to handler function as the first parameter. Your handler should process the event data and may invoke any other functions or methods in your code. Here lambda_handler(event,context) is the handler function.

Similarly, you may ask, what is a lambda function event source?

An AWS Lambda event source is the AWS service or custom application that publishes events. Lambda function is the custom code that processes the events.

What services can trigger Lambda?

Lambda can be directly triggered by AWS services such as S3, DynamoDB, Kinesis, SNS, and CloudWatch, or it can be orchestrated into workflows by AWS Step Functions. This allows you to build a variety of real-time serverless data processing systems.
