 # Image Flex
 A robust, secure, and easily deployable image resizing service that scales, optimizes, and caches images on "the edge," on the fly, built on AWS Serverless technologies. Served by [CloudFront](https://aws.amazon.com/cloudfront/) via an [Origin Access Identity](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/private-content-restricting-access-to-s3.html). Executed on [Lambda@Edge](https://aws.amazon.com/lambda/edge/). Backed by [S3](https://aws.amazon.com/s3/). Protected by [AWS WAF](https://docs.aws.amazon.com/waf/latest/developerguide/web-acl.html). Provisioned via [CloudFormation](https://aws.amazon.com/cloudformation/). Built and deployed by the [Serverless Application Model (SAM)](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/what-is-sam.html) CLI.

 The original inspiration for this application came from [this AWS blog post](https://aws.amazon.com/blogs/networking-and-content-delivery/resizing-images-with-amazon-cloudfront-lambdaedge-aws-cdn-blog/) I read a few years back. The article intended to provide a [semi-]working example, which was far from being suitable for a production environment.
 
 ## IMPORTANT!
-While Image-Flex allows you to indicate a region to use other than `us-east-1`, CloudFront requires `us-east-1`. **Until I figure out a workaround, don't attempt to deploy in any region other than `us-east-1`.**
+While Image-Flex does technically support setting a region to use other than `us-east-1`, CloudFront requires `us-east-1`. This is an AWS limitation
