Requirements for deploying locally:

• docker engine

Running locally:

• clone the project and navigate to the root directory
• docker volume create engine
• docker-compose up

Example:

• sending POST request at localhost:8080/lang/python
• attaching python code to request body

Supported programming languages:

• Java 17: localhost:8080/lang/java
• Python 3: localhost:8080/lang/python
• JavaScript / Node 16: localhost:8080/lang/javascript

Simple code snippets for testing:

• Java

public class BrainDrill {
    public static void main(String[] args) {
        System.out.println("drill my brain");
    }
}

• Python

print("drill my brain") 

• JavaScript:

console.log("drill my brain");

DONE:

• implement POC - ✅
• introduce http layer (pekko-http) - ✅
• introduce local master and worker pekko actors - ✅
• introduce Pekko Cluster - ✅
• turn local master actor into load balancer node - ✅
• create 3 worker nodes - ✅
• distribute worker actors equally on each node (e.g 25 actors on each node, awaiting tasks) - ✅
• run cluster via docker-compose - ✅
• implement timeouts & cleanup for long-running code, limit CPU and RAM, add secure layer - ✅
• write basic load test to check how system behaves during high load - ✅
• perform aggregation statistics in load test - ✅

TODO:

• add support for C, Go, Rust and others - ❌
• use other pekko libraries to make cluster bootstrapping and management flexible and configurable - ❌
• wrap the cluster in k8s and enable autoscaling - ❌
• deploy two separate clusters and enable RoundRobin load balancing via k8s - ❌
