If companies are going to use Cloud World Model to test infrastructure decisions before spending real money, they should know how closely its simulations match the real cloud.

Documentation from cloud providers is useful, but it cannot replace testing that we run, measure, and publish ourselves.

Cloud World Model now has a streaming MCP server. Paste the URL into Cursor, Windsurf, or Claude Desktop and simulate AWS/GCP/Azure/OCI/DigitalOcean architectures, inject chaos, run RL training - no install, no API key required to start.

We finished #5 Product of the Day. Here's what three days of 60+ comments actually taught us.

We launched Cloud World Model on Product Hunt last week. The pitch: simulate AWS, GCP, Azure, OCI, and DigitalOcean infrastructure without provisioning real resources. You describe an architecture compute, databases, load balancers, serverless functions and the simulator models latency curves, CPU saturation, autoscaling behavior, failure propagation, and cost. No cloud bill.

We expected interest from learners. The comments told a different story.

Something we ve been thinking about while building Cloud World Model:

If an infrastructure simulator doesn t model a particular cost, a human might recognize that the estimate is incomplete.

An RL agent may not.

We just published a technical walkthrough of how Cloud World Model handles a simulation step.

The basic idea is simple:

Current state Action Simulated next state Metrics Recommendation

We ve been building a cloud pricing history feature for Cloud World Model, and we just published our latest snapshot covering November 2025 through August 2026.

Across the 33 resources we tracked:

• Google Cloud decreased by an average of 5.3%

• AWS showed no material average change

• Azure showed no material average change

• Oracle Cloud increased by an average of 1.1%

• DigitalOcean increased by an average of 3.9%

We tried an experiment with Cloud World Model today.

We gave Grok access to our API and asked:

Try the GitHub-Inspired Cascading Retry Storm scenario and tell me what happened. Why did the outage occur?

A couple days ago, I asked a simple question here:

What should a cloud simulation actually tell you before you make a real infrastructure change?

@rabnoor_s gave an answer that changed how we re thinking about simulation results.

Well it's a pretty simple reason or benign reason.

I'm ex-OCI and my former boss is now in charge of DigitalOcean.
