Basically Lambda can be integrated with the so many AWS suite services also we can use difference programming languages like python, java,node,react etc.. and can be monitored using AWS Cloud watch.
AWS Lambda Integrations
- API Gateway: to create rest api
- Kinesis: for data transformations
- Dynamo DB: whenever a change happens in the Database the lambda functions is triggered.
- S3 : Lambda function will be triggered when a new file is created.
Lets see how to integrate cloud watch events /Event bridge with Lambda
At first Event bridge rule is created and it triggers the AWS lambda function every one hour to perform a task.
Also same way we can integrate S3 notifications with Lambda.
Basically we should get notified every time whenever an object is created, deleted, restored. So every events sent from event bridge is delievered quickly to the lamba functions like from SNS to SQS to Lambda functions.
