Replit to Cloud CI/CD

I’m building a SaaS ESG tool that I prototype in Replit, commit to GitHub, and now need running reliably for paying customers in a proper cloud production environment. I’m open to either Google Cloud or AWS and would like your guidance on which one best fits the stack; I haven’t nailed down whether that ends up being GKE, App Engine, ECS, or another service.

Here’s the flow I’m after: I continue to develop inside Replit, push to GitHub, an automated CI/CD pipeline tests, builds, and promotes to a staging space, and—once approved—deploys to the live environment. Alongside that, I need the underlying database layer planned, provisioned, and managed so that scaling later is straightforward.

Deliverables
• Cloud architecture diagram with recommended services
• GitHub-based CI/CD pipeline (build, test, deploy, rollback)
• Secure dev, staging, and production environments
• Cloud-managed database setup plus migration process
• Step-by-step documentation so I can operate and extend the setup on my own

If you’ve set up similar Replit-to-cloud workflows before, let me know the approach you took and the tools you prefer. I’m ready to start as soon as we agree on the outline.
