Server Survival is an interactive 3D simulation game where you play as a Cloud Architect. Your mission is to build and scale a resilient cloud infrastructure to handle increasing traffic loads while fighting off DDoS attacks and managing your budget.
Survive as long as possible! Manage your Budget ($) and Reputation (%).
- Earn Money by successfully processing legitimate traffic (Web & API).
- Lose Reputation if requests fail or if Fraud traffic slips through.
- Game Over if Reputation hits 0% or you go bankrupt.
- 🟢 Web Traffic (Green): Needs to be stored in S3.
- 🟠 API Traffic (Orange): Needs to be processed and saved to a Database.
- 🟣 Fraud/DDoS (Pink): Must be blocked by a WAF.
Build your architecture using the toolbar. Each service has a cost and upkeep:
| Service | Cost | Upkeep | Function |
|---|---|---|---|
| WAF | $50 | Low | Firewall. The first line of defense. Blocks Fraud traffic. |
| ALB | $50 | Medium | Load Balancer. Distributes traffic to multiple Compute instances. |
| Compute | $100 | High | EC2 Instance. Processes requests. Upgradeable (Tiers 1-3). |
| Database | $200 | Very High | RDS. Destination for API traffic. Upgradeable (Tiers 1-3). |
| S3 | $25 | Low | Storage. Destination for Web traffic. |
- Web Request: +$1.25 / +5 Score
- API Request: +$1.25 / +5 Score
- Fraud Blocked: +5 Score
- Fraud Leak: -5 Reputation
The classic experience - survive as long as possible against escalating traffic.
A fully customizable testing environment for experimenting with any architecture:
| Control | Description |
|---|---|
| Budget | Set any starting budget (slider 0-10K, or type any amount) |
| RPS | Control traffic rate (0 = stopped, or type 100+ for stress tests) |
| Traffic Mix | Adjust WEB/API/FRAUD percentages independently |
| Burst | Spawn instant bursts of specific traffic types |
| Upkeep Toggle | Enable/disable service costs |
| Clear All | Reset all services and restore budget |
No game over in Sandbox - experiment freely!
- Sandbox Mode: Full control over budget, traffic rate, traffic mix, and burst spawning
- ESC Menu: Press ESC to pause and open main menu, Resume to return (stays paused)
- Service Upgrades: Click on Compute or Database instances with their respective tools to upgrade them.
- Tier 2: Increased capacity (Cost: $200/$400).
- Tier 3: Maximum capacity (Cost: $250/$600).
- Smart Load Balancing: ALBs now use Round Robin to distribute traffic evenly across all connected instances.
- Visual Feedback: Upgradeable services glow when hovered, and rings indicate their current tier.
- Left Click: Select tools, place services, and connect nodes.
- Right Click + Drag: Pan the camera.
- ESC: Open main menu and pause game. Press again or click Resume to close menu (stays paused).
- Camera Reset: Press
Rto reset the camera position. - Birds-Eye View: Press
Tto switch between isometric and top-down view. - Hide HUD: Press
Hto toggle UI panels. - Connect Tool: Click two nodes to create a connection (flow direction matters!).
- Valid Flows: Internet -> WAF -> ALB -> Compute -> (DB/S3)
- Delete Tool: Remove services to recover 50% of the cost.
- Time Controls: Pause, Play (1x), and Fast Forward (3x).
- Block Fraud First: Always place a WAF immediately connected to the Internet. Fraud leaks destroy reputation fast.
- Scale Compute: As traffic increases, a single Compute node won't be enough. Use an ALB to split traffic across multiple Compute nodes.
- Watch Your Queues: If a service's queue fills up (red ring), requests will fail. Add more capacity!
- Budget Wisely: Databases are expensive. Don't over-provision them early on.
- Core: Vanilla JavaScript (ES6+)
- Rendering: Three.js for 3D visualization.
- Styling: Tailwind CSS for the glassmorphism UI.
- Build: No build step required! Just standard HTML/CSS/JS.
- Clone the repository.
- Open
index.htmlin your modern web browser. - Start building your cloud empire!
