Udemy - the world’s biggest online education platform
The history of Udemy dates back to 2007 when Eren Bali came up with an idea of creating software for a live virtual classroom.
The first attempt at launching an online education marketplace was not successful. So Bali and his friend Oktay Caglar moved from Turkey to Silicon Valley where they gave their project another try. Firstly, the idea did not seem appealing for the investors. Finally, in 2010 the platform saw the light of the day.
Today Udemy has over 57,000 instructors offering courses in 65 languages.

The stack of technologies used by Udemy
When it comes to the server-side, there are a great number of programming languages to choose from. For example, the Codica team creates fast-loading, user-friendly, and scalable online marketplaces with the help of Ruby.
As for Udemy, at first, it used PHP together with a custom MVC framework. However, later the company switched to Python and the process has not completed yet.
Regarding databases, MySQL is the ultimate choice for Udemy. Also, ElasticSearch is a great tool for search and analytics.
- Third-party tools and integrations
Udemy uses lots of applications and tools to achieve different business goals. They include Trello, Dropbox, Slack, Salesforce, and Zendesk
The stack of technologies used by Coursera
According to Brennan Saeta, an infrastructure engineer at Coursera, the first lines of this e-learning platform were written on PHP. Then the engineering team grew, and Python and Go were used for a short period of time. Finally, Coursera settled upon Scala, which is still used by platform developers together with the Play framework.
Similar to Udemy, Coursera manages relational databases with the help of MySQ. Also, the web-server called Nginx and such Cloud storage as Amazon S3 are widely used by the company.
