Seminar Informatik WS 1415 Verteilte Systeme: "Consistency and Fault Tolerance in Geo-replicated Data Stores"

Registration is now available via Email and in person.

*Kick-Off Meeting* Wednesday 15 Oct. 2014, 15:00-16:00, (IZ Raum 105)

05.11.2014 - 28.01.2015 Wednesday, 15:00-16:00 (IZ Raum 105)

Overview

Geo-replicated, distributed data stores that support complex online applications, such as social networks, must provide an “always-on” experience where operations always complete with low latency. The CAP Theorem, unfortunately, proves it impossible to create a system that achieves all three: Consistency, Availability and Partition-tolerance. Besides, most such systems assume benign fault model which can’t depict the malicious behaviours caused by Byzantine Faults. Robusted and trustworthy data stores with Byzantine Fault Tolerance (BFT) are highly desired to maximize the safety and liveness properties of corresponding services. In this seminar, we are going to show you the latest technologies from both academia and industry, which explore the solutions to leverage the essential trade-offs among all aspects. Our seminar covers both fundamental and most crucial topics:

• State Machine Replication (SMR)-based Fault Tolerance
• Original BFT and Improved BFT Protocols
• Consistency Semantics in Data Stores
• Fault Tolerance and Rubustness in Data Stores

Seminar Topics

Course

This seminar will be given in English. Each participant will take one or more papers under a specific topic. Participants are responsible for a peer review, including:

• Attend peer's presentation dry run and give feedback.
• Review peer's report before submission.
• Collect questions to peer's presentation during discussion session.

Notes

Please submit the report together with your presentation slides after your talk. The requirements for presentation and report are listed as follows:

• Please give presentation and finish report in English.
• Presentation takes 20 - 25 minutes.
• Report should be written within 6-10 pages, including summary of paper(s), background knowledge, your own thoughts and meaningful Q&A of your talk.

Each paticipant is supposed to do further research based on the paper. The supervisors are always glad to help in this case.

The strength of the university depends on academic and personal integrity. In this seminar, reports must be done in your own words. Plagiarism is an offense against the examination regulations.

Templates

LaTeX templates for report and presentation slides can be found here.
