Build your own private cloud lab — free, fast, and fully under your control.

Cloud Jam Gauntlet: Sovereign Systems Foundations is a self-paced, hands-on journey where you launch your own private cloud lab and learn to run it like a pro — without risking production, racking up an AWS bill, or handing your skills to a single vendor.

Cloud Jam runs in your browser and on your hardware. You’ll spin up virtual machines, test apps, and practice real-world cyber operations in a safe, isolated environment that you control.

Why Cloud Jam matters

Most people “learn the cloud” by watching videos or copying screenshots — and then freeze when it’s time to touch real infrastructure.

Cloud Jam flips that.

• Train safely. Practice incident response, automation, and deployments in your own lab instead of on production systems.
• Own your skills. Every lab you build lives inside your Nexus — you control the data, the AI, and the tools.
• Level up fast. Complete the Gauntlet to earn credentials and unlock access to the Sovereign Research Institute and advanced training.

What is the Cloud Jam Gauntlet?

The Cloud Jam Gauntlet is a guided, pay-what-you-want experience where you’ll build the foundations of your own sovereign cloud system — a digital environment that you fully control, designed to learn, adapt, and defend itself.

This is not a passive course or a vendor training. It’s a modern rite of competence for builders who want to be able to spin up infrastructure anywhere, follow real documentation, and trust themselves under pressure.

“Don’t just learn the cloud. Become the architect of your own.”

What you’ll actually do

• Launch your lab. Use Underground Nexus to bring up a secure, browser-based cloud lab on your own machine.
• Work at the command line. Get comfortable with shell workflows you can reuse on AWS, Azure, GCP, or bare metal.
• Follow real guides. Practice reading and executing technical documentation so you can navigate any vendor’s docs with confidence.
• Tour the stack. Move through networking, services, logs, and automation — seeing how the pieces fit together instead of learning them in isolation.
• Survive “trial by chaos.” Run a guided chaos test against your own setup and harden it until it holds.

Skills you’ll build in the Gauntlet

By completing Cloud Jam, you’ll practice skills that map directly to real roles and projects:

• Cloud engineering and architecture
• DevOps / DevSecOps practices
• Cloud-native and container-based software deployment
• AI and agentic infrastructure basics
• Critical infrastructure and hardware-aware thinking
• Home lab, smart home, and data-lakehouse-style setups

These skills are especially valuable if you’re an entrepreneur, freelancer, or technical founder who wants to own your own infrastructure instead of renting it in someone else’s walled garden.

By the end of the Gauntlet, you will have:

• A functioning private cloud lab you can reuse for experiments, demos, or client work.
• Hands-on experience following documentation, debugging issues, and finishing what you start.
• A clear view of how to grow into more advanced paths — including building a Digital Twin and joining the Sovereign Research Institute.

Who Cloud Jam is for

• Engineers & DevOps practitioners who are tired of vendor-locked training and want portable, agnostic skills.
• Founders & solo builders who want to run their own infrastructure and keep their data, IP, and systems sovereign.
• Career switchers & learners who want a concrete project they can point to instead of just certificates.
• Security-minded tinkerers who want a safe place to practice incident response and chaos without breaking anything important.

If you’re willing to think for yourself, try new things, and finish what you start, the Gauntlet is designed for you.
