Building a Serverless Markdown‑Driven Blog on AWS

Welcome to the future of lightweight publishing. In this article, we’ll explore how to build a fully serverless, zero‑maintenance, Markdown‑powered blog using AWS services.


Why Serverless Blogging

Serverless architecture gives you:

  • No servers to patch
  • No CMS to maintain
  • No plugins to break
  • No database to scale
  • Near‑zero cost

It’s the perfect setup for a personal blog or documentation site.


Architecture Overview

Here’s the high‑level flow:

  1. Upload a Markdown file to content/input/
  2. S3 triggers a Lambda function
  3. Lambda:
  4. Parses YAML front‑matter
  5. Converts Markdown → HTML
  6. Applies your HTML template
  7. Writes the final page to the site bucket
  8. CloudFront serves the static site globally

Code Example

Here’s a small Python snippet showing how the Lambda converts Markdown:

```python import markdown

def convert(md_text): return markdown.markdown(md_text)
