The application is hosted on azure app service with Tomcat 9.0

Article creation and view is done through rest APIs using spring.

Each article gets stored as a article object on the server which is used to view them and for avoiding multiple articles with the same name/url a serializable red black tree is used (i could have used an array, but tree will provide better complexities) which stores the article object name/url.

After uploading an article the server responds with the link, with which it can be accessed later.
