{“description”:”Developed a fully-functional Django web app that runs as a AWS Lambda Function, with static assets hosted on AWS Cloudfront. The production site is infinitely scalable, requires no load balancing and no human monitoring nor intervention. Monthly fixed hosting costs are $0.00. More details on how to duplicate this deployment methodology are available in my blog article, Serve a Django App from an AWS Lambda Function.”,”images”:[“https:\/\/cdn-blog.lawrencemcdaniel.com\/wp-content\/uploads\/2018\/12\/06074203\/django-serverless-aws3.png”]}
