Triggers

AWS Lambda support AWS services that you can configure as event sources:

• Amazon S3
• Amazon DynamoDB
• Amazon Kinesis Streams
• Amazon Simple Notification Service
• Amazon Simple Email Service
• Amazon Cognito
• AWS CloudFormation
• Amazon CloudWatch Logs
• Amazon CloudWatch Events
• AWS CodeCommit
• Scheduled Events (powered by Amazon CloudWatch Events)
• AWS Config
• Amazon Alexa
• Amazon Lex
• Amazon API Gateway
• Other Event Sources: Invoking a Lambda Function On Demand
• Sample Events Published by Event Sources

Ardy actually support integration with S3, SNS and loudWatch Events. The worst integration of AWS Lambda is the trigger configuration. You can’t see all triggers as a glance in your lambdas configuration and, if you use whe AWS Cli, each trigger is configured outside AWS Lambda, it’s mean, a trigger of S3 is a Event of a S3 bucket; a trigger of SNS is a subscription of a SNS Topic.
