If you need to troubleshoot, check the AWS CloudWatch logs for details of each call to your Lambda function.
The Lambda function would execute whenever a new stream record appears, but only process new items added to the Customers table.
Our Lambda function will be subscribed to these S3 bucket notification events.
Each AWS Lambda function runs in its own isolated environment, with its own resources and file system view.
Create an SNS Topic to connect to your CodeDeploy application and the Lambda function 2.
The codes that are run on the Lambda are called“Lambda Function”.
When a“Create Account” event is triggered, the respective nanoservice is executed as a AWS Lambda function.
Looking at the AWS Lambda service, you will see the new DeepLearning_Lambda function.
An event source is an AWS service or developer-created application that produces events that trigger an AWS Lambda function to run.
In addition, AWS Lambda supports versioning and aliasing, which let you quickly switch between different variations of your Lambda function.
I go to the Lambda Console and create a Lambda function using the Python 2.7 runtime(the IAM role does not matter here).
This role defines the permissions scheme that the Lambda function will run under- in this case, we're granting Lambda access to the S3 bucket.
For example, each time a person arrives at your residence, your door camera can upload a photo of the visitor to Amazon S3, triggering a Lambda function that uses Rekognition API operations to identify your guest.
If you're a developer and already comfortable with AWS, you may want to jump straight to the Lambda function in Step 3, or just grab the example code from GitHub and get up and running yourself.
For example, a Lambda function that is invoked when an image is uploaded to an S3 bucket could insert an item into a DynamoDB images table and publish a message to a Kinesis stream to trigger image processing.
Uploading a file to the bucket will trigger our Lambda function, which composes and submits a request to the Zencoder API to create an encoding job.
In most cases, either an Amazon Simple Notification Service(SNS) notification mechanism is used or user code placed inside an AWS Lambda function is automatically triggered.
That's it We have got an S3 bucket with a watch folder and we have got a Lambda function that receives file creation events from that watch folder, which forms a Zencoder job to transcode those files and drop them back into our output folder.
This will ensure the Lambda function is only triggered when files are added to that folder, and not elsewhere in the bucket- and most importantly, this will also prevent our output files from triggering more encoding jobs in an endless loop.
For example, if you use the Amazon SES endpoint in US West(Oregon), then any Amazon S3 bucket, Amazon SNS topic, AWS KMS key, and Lambda function that you use must also be in US West(Oregon).
