Reading Group 151. Towards Modern Development of Cloud ApplicationsReading Group 151.
We kicked off the winter term set of papers in the reading group with the “Towards Modern Development of Cloud Applications” HotOS’23 paper. The paper proposes a different approach to designing distributed applications by replacing the microservice architecture style with something more fluid. The paper argues that splitting applications into microservices from the get-go can…

Reading Group #149. On-demand Container Loading in AWS Lambda
For the 149th paper in the reading group, we read “On-demand Container Loading in AWS Lambda” by Marc Brooker, Mike Danilov, Chris Greenwood, and Phil Piwonka. This paper describes the process of managing the deployment of containers in AWS Lambda. See, when AWS Lambda first came out, its runtime was somewhat limited — users could…

Metastable Failures in the Wild
Metastable failures in distributed systems are failures that “feed” and strengthen their own “failed” condition. The main characteristic of a metastable failure is a positive feedback loop that keeps the system in a degraded/failed state. These failures are hard to spot, as they always start with some other distraction — some trigger event that nudges…

One Page Summary. Photons: Lambdas on a diet
Recently, to prepare for a class I teach this semester, I went through the “Photons: Lambdas on a diet” SoCC’20 paper by Vojislav Dukic, Rodrigo Bruno, Ankit Singla, Gustavo Alonso. This is a very well-written paper with a ton of educational value for people like me who are only vaguely familiar with serverless space! The…

Reading Group. Multitenancy for Fast and Programmable Networks in the Cloud.
We discussed “Multitenancy for Fast and Programmable Networks in the Cloud” in the 59th DistSys Reading Group meeting. In a sense, this was a continuation of a previous discussion we had a few months ago when covering Pegasus paper. Pegasus and many other new protocols rely on specialized programmable network hardware that is not yet…

Reading Group. New Directions in Cloud Programming
Recently we have discussed a CIDR’21 paper: “New Directions in Cloud Programming.” Murat Demirbas did the presentation: Quite honestly, I don’t like to write summaries for this kind of paper. Here, the authors propose a vision for the future of cloud applications, and I feel that summarizing a vision often results in the misinterpretation of…

Paper Summary: Bolt-On Global Consistency for the Cloud
This paper appeared in SOCC 2018, but caught my Paxos attention only recently. The premise of the paper is to provide strong consistency in a heterogeneous storage system spanning multiple cloud providers and storage platforms. Going across cloud providers is challenging, since storage services at different clouds cannot directly talk to each other and replicate the…
