I just finished up a POC for an integration with a major retailer that allows our Customer Engagement Center to better assist customers buying custom blinds in store. It leverages AWS Lambda, AWS API Gateway and AWS SES to deliver a massively scalable, highly available web API with no servers to manage. I am really liking the tools provided by the JAWS Framework that made it far easier to manage and deploy the solution. I hope to do a full blog post on this in the near future.
