The 30% AWS Cut. An Engineer's Guide to Cloud FinOps, Infrastructure Automation, and Unit Economics using Python and Terraform - Ashish Prasad

The 30% AWS Cut: An Engineer's Guide to Architecting for Unit Economics

Stop donating your margins to the cloud provider. Move beyond "On-Call" and start building for "On-Value."

Is your AWS bill eating 30% or more of your SaaS revenue? Most DevOps engineers are trained to build for scale, but few are taught to build for profitability. This book bridges the gap between high-level cloud architecture and the brutal reality of unit economics.

Written by a DevOps veteran, this guide provides a technical roadmap for engineers who are tired of repetitive "Ops" work and ready to command the architecture of value.

Part I: Stop the Bleeding. Immediate ROI strategies to hunt down "Zombie" EBS volumes and bypass the silent $0.045/GB NAT Gateway data processing trap.

Part II: Core Infrastructure Optimization. Learn the "Fear of Downtime" tax. We analyze CloudWatch metrics to right-size RDS/DynamoDB and identify the exact "Tipping Point" where Serverless Lambda becomes more expensive than Fargate.

Part III: The Silent Accumulators. Master S3 Lifecycle management and Storage Lens to eliminate "Ghost Storage" fees through automated tiering.

Part IV: Real-World Case Study. A deep dive into architecting a lean, privacy-first Micro-SaaS. Learn how to calculate the exact AWS cost per active user.

This isn't just theory. Each chapter includes:

Boto3 & Lambda Scripts: For automated cleanup and FinOps guardrails.

Terraform Snippets: To deploy Gateway Endpoints and Fargate Spot integrations via Infrastructure as Code.

10-Minute Action Plans: Checklist-style summaries for immediate implementation.

DevOps & Cloud Engineers: Ready to move into Architectural roles and master the financial side of cloud infrastructure.

SaaS Founders & CTOs: Who need to optimize their burn rate and understand the true cost of their tech stack.

Python Developers: Looking to apply their skills to infrastructure automation and financial modeling.

Platform Engineers: Dedicated to building internal tools that make cost-efficiency a default setting.

Stop viewing AWS as a utility bill and start viewing it as a profit lever. Grab your copy of "The 30% AWS Cut" today and architect your way to a leaner, more profitable cloud.
