Overview
Modern software applications are large and complex. However, there are common patterns and approaches to designing architectures that satisfy functional requirements while supporting scalability, consistency, and high availability.
In this course, we will examine architectures that underpin large-scale, real-world systems such as Uber, Yelp, TinyURL, and Ticketmaster. Through analysing these systems, we will trace the evolution of a system serving tens of users into one capable of serving millions.
Learning highlights
- Real-world applications consist of multiple components, including a load balancer, database, message queue, and object store (such as S3). We will explore how these components work together to build reliable and useful applications. Much of the programme is dedicated to in-depth analysis of case studies, including Uber, TinyURL, Ticketmaster, and the Twitter newsfeed.
- Software runs on hardware and network infrastructure that is prone to faults. We will learn how to design systems that remain reliable in the face of failure. Students will develop the ability to present and defend their system designs effectively. They will also work collaboratively to discuss the trade-offs between different solutions.

Acquaintance with distributed systems
Acquaintance with SQL databases
Methodology
The course mainly consists of case studies of different systems. The common framework for approaching a design will be given in the first session.
Students will be working in groups of up to 3 people on a final project. The goal of the final project is to design the system of students’ choice. The system may be their existing or a new project. Implementing the systems, e.g. writing code is not required. However the system design should be detailed enough to implement the system.
Each session will consist of a lecture and a quiz based on the lecture. An important part of the course is class discussions and presentations. During practical sessions, students will work with technologies in a Docker container to gain hands-on experience. A homework assignment will be given to reinforce classroom learning.
