Highlights

1. Pillow==4.1.1 compiled to be usable with AWS Lambda
2. Python scripts for the actual compression

How to use

1. Understand what is Lambda and how to use it: Getting Started with AWS Lambda. Also check out how to work with Python on AWS Lambda: Packaging for Lambda
2. Go through the architecture in the accompanying blog: Leveraging AWS Lambda for Image Compression at scale
3. Deploy orchestrator.py and image_compress.py using AWS Lambda.
4. Invoke the lambda for orchestrator with a payload like:

   {
   "key_urls_map": {
           "image1.jpg": "https://media.licdn.com/media/p/8/005/05b/1fb/0cf50ca.png",
           "image2.jpg": "https://media.licdn.com/media/p/8/005/05b/1fb/0cf50ca.png"
       },
   "quality": 90,
   "bucket_name": "compression-test-bucket"
   }

5. Check your S3 bucket for the compressed images^
