Amazon Simple Storage Service S3 Object Lambda Icon

Amazon S3 Object Lambda lets you run custom code on your data stored in Amazon S3 without downloading it first. This means you can process, transform, or filter your data in real-time, only retrieving the parts you need. This saves on costs and bandwidth, making it useful for handling large datasets or when you need to access specific parts of your files efficiently. It's particularly beneficial when working with image or video processing, data analysis, or serving customized views of your data.
