This repository contains source code for APC portal. This portal is used by students and teachers to assign, submit and test programming homeworks.
Reason for implementing our own solution was having ability to run different tests on submission by students and running even more tests by teacher later.
One of our primary targets was to create system with low maintenance costs. For this reason we used Azure serverless solutions as much as possible.
This project consists of these logical parts:
- Frontend - Javascript (React) application (hosted on Azure BLOB Storage)
- Backend - Azure functions (on consumption plan)
- Database - We choose Azure Cosmos DB with Mongo API (can switch to real Mongo)
- Tester - Python commmand line script able to compile (gcc + msvc) and test source codes
- API Mangement - Azure gateway for our backend, used to handle Google Auth and limit request rate
- Virtual machine - Azure VM able to run docker orchestrator.
- Go services - Services to run Tester scripts and communicate with our Backend
Because test and submissions are usually happening more often when submission deadline approaches, vms are automatically turned off and deallocated by azure orchestration functions (via automation account). These are then turned on automatically, when test request is queued.
Communication between our backend and Go services running in VM is signed via JWT, due to not having dns names for testers (it could be done, but who would do it 😀)
Here is basic directory structure for this project, some of these might have their own READMEs.
