I'm Nolan Peet. I like to do stuff that is interesting
This project was pretty fun, its a very compact bit of code all hosted on AWS all for free.
I'm using AWS API Gateway to serve html with embedded JS through a REST api. The api uses AWS Lambda integrations written in python to run the logic for my webserver.This includes serving files from my self-hosted websites for a low-cost solution, or load-balancing with AWS mirror backups for a cloud-based backup.
AWS gives enough cloud compute time for free to run simple serverless web applications like this forever with 0 oversight. Combining Lambda automation scripts with self-hosted endpoints can help me distribute my network more securely and with greater availability through AWS proxies.
