Amazon Simple Storage Service (S3) lets you store, retrieve, update, and version objects in the Cloud. Not only does it guarantee durability and high availability at low cost, but it also enables event-driven systems by notifying you whenever objects are created, updated, or deleted. This lets you connect S3 to SQS queues, SNS notifications, or AWS Lambda for custom processing.
In this lab, we will learn how to process new image files uploaded into S3 with a Lambda Function. As a simple example, we will use Python to compress the input image and generate a gzipped version.
Upon completion of this lab you will be able to:
Experience with S3 and the Lambda command-line will be beneficial but is not required.
The following courses can be used to fulfill the prerequisites:
