Verbundprojekt »The Microservice Dungeon« (The Microservice Dungeon), WS21

The Microservice Dungeon is a large, interconnected project in WS 21/22, where four modules in three study programs interact. There will be ca. three months of joint preparation, and then we will have a 1.5 week Hackathon in January 2022 - with the goal to build a large microservice architecture, where robots swarm through a dungeon and fight each other.

Game Idea

In small teams (or as solo players) the students will implement autonomous robot swarms, who compete for resources (e.g. mining) and fight each other in a dungeon. Each robot swarm is a microservice - with complete freedom of choice wrt. technology. Central services such as dungeon, mining exchange, trading, robot registry (and whatever else we need) each also are services. The robots communicate via REST (submitting commands) and asynchronously - for example, listening to events to follow the moves of their opponents.

The individual teams keep their code secret, so they can implement sophisticated algorithms to “trick” others teams, so that they are able to cleverly secure resources, or attack others. In the game, an economy will be defined. I.e. everything costs - spawning new robots, moving robots, attacking, defending, etc. Money can be earned by mining, or by successful attacks.

A Dungeon of Planets

The dungeon represents the gameworld and is one of the central services in our microservice dungeon game. It consists of several planets, connected with other neighbouring planets1.

Dungeon Example

(Graduates of ST2 in SS20 will find this a bit familiar. In fact, the idea takes the practical assignment for ST2 to the next level: The goal is to implement a loosely coupled architecture according to DDD principles (i.e. a microservice application) in a realistic size.

Four coupled modules - and their roles

For this project, four modules in three study programs will come together - this is pretty new, complex, and innovative. The students will take up different roles, as shown below.

Literature

If you want to prepare: In this project, you can apply your DDD and coding knowledge (… what you learnt in ST1 and ST2 …) to a real application. The following books I can recommend. You can access online versions from the TH Köln VPN.
