4 ECTS points / 3 Contact hours

2nd Semester



The students acquire knowledge about techniques and concepts of distributed systems using the example of web applications. In particular, they acquire skills to explain the general architecture of the Internet and the Web, to analyze requirements of a Web application, to create an interactive Web application with HTML, CSS and client-side JavaScript, to identify security issues in a Web application and to develop server-side code for application services with authentication, cookies and sessions.

Course Distributed Systems 1



Prof. Dr. Christian Zirpins



Written Exam 90 Min. (graded)

The course provides a practical introduction to the concepts and paradigms of distributed systems using the example of web technologies and application development on the web. This initially involves an introduction of the world wide web with basic protocols such as HTTP and other standards in the context of the Internet. After that an introduction to the design and construction of web applications is provided. This includes firstly the frontend development with HTML5, CSS3 as well as client-side JavaScript and secondly the backend development with server-side JavaScript on the Node.js platform. Interactions between frontend and backend follow modern REST/HTTP and AJAX techniques. In addition, mechanisms for personalization with cookies and sessions as well as to authenticate users are presented. The course closes with a detailed discussion of web application security.
