DriftSpend¶

DriftSpend is a lightweight, serverless cost‑analytics solution designed to give you fast, automated visibility into your weekly AWS cloud spend — without dashboards, heavy infra, or manual Cost Explorer clicks.

It collects daily cost data, aggregates and analyses it weekly, and delivers a clean HTML report straight to your inbox. An optional static dashboard provides a secure way to explore the latest results.

Why I Built DriftSpend¶

Working daily with AWS, I wanted a simple, automated way to stay on top of cloud costs across regions — without having to log into the AWS console, click through Cost Explorer, or remember to check dashboards.

The problem was simple:

• AWS billing data is powerful but not proactively delivered.
• Costs can drift quietly, especially in multi‑region setups or during development spikes.
• Dashboards require manual effort and context switching.

So I built DriftSpend as a lightweight, low‑maintenance solution:

• It collects and analyses spend automatically.
• It sends a clean, mobile‑friendly weekly email, so insights come to me — not the other way around.
• It adds optional dashboards only when needed, keeping the workflow lean and efficient.

DriftSpend trims away the noise I don’t need and delivers exactly the visibility I want.

What DriftSpend Provides¶

📡 Automated Cost Collection¶

A daily Lambda job queries AWS Cost Explorer and stores normalized snapshots in S3.

📊 Weekly Spend Insights¶

A weekly job aggregates data and produces:

• Total spend for the period
• Top services and their contribution
• Regional breakdowns
• 30‑day and 90‑day projections
• Week‑over‑week trends

Delivered via responsive HTML email.

🔒 Secure, Minimal Footprint¶

• Fully serverless (Lambda + S3 + SES)
• No persistent compute
• Private bucket & least‑privilege IAM
• Optional CloudFront‑secured dashboard

📁 Optional Static Dashboard¶

The weekly reporter can publish a small HTML dashboard to S3/CloudFront for at‑a‑glance visibility.
