Reliability in Modern Cloud Systems
Cloud systems power a large fraction of the computing world today. Ensuring that these systems are correct and performant remains a key challenge that continues to bedevil developers. In this seminar, we will explore various themes around the various forms of reliability in modern cloud systems as well as learn about state-of-the-art strategies for mitigating incidents and understanding issues in modern cloud systems today.
Pre-requisites: Programming 2, Software Engineering Lab (Praktikum)
Recommended: Distributed Systems
Places: 20
Lecture Time: Wednesdays, 2:15pm-3:45pm
Room: TBD
Format
Each lecture will be divided into 2 parts:
- Lecture Part: In this part, the instructors will give a lecture on a specific topic in reliability.
- Discussion Part: In this part we will discuss the assigned reading and the previous week's lecture.
Assignments
All assignments will be based on Blueprint, a toolchain for generating microservice implementations and for exploring the design space of microservices.
