*Coursetune is a robust application, similar to using AutoCAD or video editing tools. If you use multiple, demanding applications you might need higher specs for the best experience.

Overview

Coursetune consists of a rich-client/SPA (single page application), ”restful” server services, in which the servers receive and handle very simple requests and the client application is responsible for presentation & user interactions. This provides a very simple & clean separation of concerns and works well when presented in a browser as well as “an app” on a mobile platform. It also scales very well to growing numbers of users & user interactions. On top of this we have added a real time data streaming service, using “push” technology, to make authors and contributors able to cooperate seamlessly, not having to deal with saving & refreshing browser pages.

We keep source code & assets in an SCM-system and we have a CIS (continuous integration system) in place, building automatically to all environments and deploying automatically to our development & QA environments. We have a fully automated provisioning system for setting up the services on Google Cloud.

On top of our own stack, we use reliable, tried and tested, high performance open-source components.

Client tech

The client application/web site is executed in javascript and renders using html/html5.

Server tech

Server programming is done in Go, NodeJs and DotNet, some of the fastest and simplest to develop in runtime systems that exist. An ocean of free, open-source, high-quality components exist for any purpose we need.

For databases we use PostgreSQL, generating automated backups every 24 hours.
