Introduction

Fake Client Brief is the first platform dedicated solely to Cloud Engineering scenarios. We simulate the messy reality of designing distributed systems, where constraints like Cost, Latency, and Compliance matter more than clean code.

For Juniors

  • •Practice gathering requirements from a difficult AI Client
  • •Move beyond "To-Do Apps" to real distributed systems
  • •Learn trade-off thinking (e.g., Cost vs Performance)

For Seniors

  • •Showcase your specialized System Design knowledge
  • •Mentor the community by reviewing architectural diagrams
  • •Keep your skills sharp with constraints like FinOps & Compliance

The Philosophy: "It Depends"

In software, there is often a "clean" way to write a function. In the Cloud, there is only "trade-offs". Should you use DynamoDB or RDS? Lambda or Fargate?

"The goal isn't just to build it. The goal is to build it so it doesn't bankrupt the client when they scale to 1 million users."

Our AI Client pushes you to justify these decisions. They won't just ask if it works; they'll ask why the monthly bill is $5,000.
