AWS Lambda : S3 Event Notification

The Amazon S3 notification is a feature that enables you to receive notifications when certain events(put, delete, modify, etc.) happen in your bucket. There can be three types of target that can be added as a Destination - SNS topic, SQS queue or Lambda function.

Perfect Tutorial ! This worked fine for me. I am making an API call on the trigger and sending necessary data to my another lambda function. Is there a way that could be replaced without API call to communicate with another lambda to pass necessary data ?

Could you elaborate your flow?

So I was able to trigger lambda based on S3:ObjectCreated by uploading a file. But what happens when the whole S3 bucket region is down? In this case, the file won't be uploaded to the bucket and won't trigger the lambda. In this case, what do we do to still process the file when the bucket region is down?

The service tries it's best to keep up with the availability -
