🏗️ Infrastructure

The project uses Terraform for infrastructure management. Configuration can be found in the terraform/ directory.

This project uses the following services:

• Cloudflare CDN
• GCP Cloud Run (Webapp, Router)
• GCP Cloud Run Jobs (Static Builds)
• GCP Batch (Server builds by orchestrating isolated VMs)
• Neon Postgres (Cloud SQL is too expensive)
• Upstash Redis (Cloud Memorystore is too expensive)
• GCP Cloud Bucket (Static site builds)
• GCP Artifact Registry (Docker images for server builds)
• GCP Eventarc (Webhook triggers)

$_2$: Google Cloud Run configured with multiple concurrent requests with autoscaling are used to create the same behaviour as Vercel Fluid Compute
