About Server Survival

Build a cloud that survives real traffic: place firewalls, load balancers, servers and databases, link them up, and keep the requests flowing.

Server Survival is a 3D strategy game about running cloud infrastructure. Requests arrive from the internet and each type has to reach the right place: static files and uploads go to storage, reads and writes go to a database, and malicious traffic has to be stopped by a firewall. You earn money for every request served and spend it on more services, but each one has upkeep, degrades under load and can fail. Survival mode ramps the traffic up until your budget or reputation runs out. The 25-level campaign teaches one idea per level, such as caching, autoscaling, queues, circuit breakers and multi-region failover. Sandbox mode removes the budget so you can experiment. Progress and an unfinished run are saved in your browser.

Server Survival sits in our strategy & td games lineup. Tower defense, conquest and tactics.

How to play Server Survival

Pick a service from the bottom toolbar and click the board to place it, then use Link (C) to connect it to the next service. Press Play to start the traffic.

1. Choose Start Survival, Campaign or Sandbox from the menu. The tutorial walks you through your first setup.
2. Select a service in the toolbar (tabs 1-5 switch categories) and click the board to place it.
3. Choose Link and click two services in turn to route traffic from the first to the second.
4. Press Play, watch the service health and finance panels, and add capacity before a traffic surge.
5. Click damaged services to repair them, or turn on Auto-Repair for a fee.

Tips for Server Survival

• Place a firewall early: malicious requests that slip through cost reputation, not just money.
• Send static files and uploads to storage and reads and writes to a database; requests that reach the wrong service fail.
• Watch the Next RPS Surge timer and add capacity before it hits, not after services start failing.
• Every service has upkeep, so remove ones you no longer route traffic through.
