Serverless Blog! AWS Lambda, API Gateway, CloudFront and S3

I wanted to set up a little blog for myself so that I had a place to document all the shitty little projects home automation projects that I do, as well as a place to highlight whatever else I find that I think is interesting but would probably bore the shit out of my wife or other people around me, so this is it!

This blog is "serverless" and powered by a series of AWS services, instead of your traditional webserver architecture. Full credit for the architecture on this goes to Matej Šircelj who laid the groundwork for all this. Be sure to check out his github repo:

It's pretty slick in how it works. Essentially, instead of your request being routed to a standard web server,  your request gets sent to an API in AWS API Gateway, which parses the request and parameterizes whatever data comes with it, and then it invokes a corresponding Lambda function, which fetches whatever data it needs from DynamoDB and/or S3, renders the templates and returns the response. Static assets are also hosted in an S3 bucket and the routing and caching is handled by CloudFront.

All of this happens on request-- meaning I'm not paying for a server to run just to sit and wait for the 1 visitor who might stop by every other month. Pretty dope, eh?

Here's a bit of a visual breakdown (image credit also goes to the projects original author):

I've forked the repo and made some changes-- notably, adding some data fields for the posts, refactored some of the lambda functions to move some data around, and then cobbled together this stunning front-end.

This was dead-simple to get up and running, and you can find the project's github repo here.
