Guide to AWS Lambda Triggers
What is AWS Lambda Triggers:
AWS Lambda Triggers are components that start the function's execution. Triggers could be changes in data state, system state, user action, or from other AWS services.
Why Lambda Triggers are important:
Lambda triggers are vital because they allow for automatic scaling, running code in response to certain triggers, and creating a seamless system of tasks that work in response to changes in your AWS environment.
How AWS Lambda Triggers work:
The Lambda Triggers are essentially components that start the execution of Lambda Functions. For instance, if an image is uploaded to an S3 bucket serving as a trigger, AWS Lambda could be configured to automatically create a thumbnail of that image.
Exam Tips: Answering Questions on Lambda Triggers:

Lambda Triggers practice test
Lambda Triggers are the AWS services or resources that can invoke or start an AWS Lambda function on specific events. These services include Amazon S3, Amazon DynamoDB, Amazon Kinesis, and various other AWS resources. The Lambda function accepts an event in JSON format that contains information related to the triggering event, which helps the function to process the data as per the requirement. Using Lambda triggers allows you to create event-driven processing pipelines, serverless data processing, and decouple your application components to improve the scalability and manageability of your applications.
