Highly Available Transactions: Virtues and Limitations

Highly Available Transactions: Virtues and Limitations - Bailis et. al 2014. Since yesterday we looked at the Boom Hierarchy, it seemed fitting today to take a selection from the BOOM project (no relation). Thus earning me the Basil Brush award ;) What a great paper this is, I have so many highlights and annotations on … Continue reading Highly Available Transactions: Virtues and Limitations

Leases: An efficient fault-tolerant mechanism for distributed file cache consistency

Leases: An efficient fault-tolerant mechanism for distributed file cache consistency - Gray & Cheriton 1989 This paper introduced the leasing model for distributed systems. Leases are conceptually very straightforward and bring a surprising number of benefits for such a simple mechanism. Also in this paper you'll find the simple formulas that can help you figure … Continue reading Leases: An efficient fault-tolerant mechanism for distributed file cache consistency

Improving Cloud Service Resilience using Brownout-aware Load Balancing

Improving Cloud Service Resilience using Brownout-aware Load Balancing - Klein et al 2014 This is what the previous two #themorningpaper selections have been building to. What happens when you apply brownout techniques to a set of load-balanced servers? We study how to extend the classical cloud service architecture composed of a load-balancer and replicas with … Continue reading Improving Cloud Service Resilience using Brownout-aware Load Balancing

Brownout: building more robust cloud applications

Brownout: building more robust cloud applications - Klein et al. 2014 How can we design cloud applications to be resilient in the face of varying resources and user load, and always deliver the best possible user experience? That's a pretty important question these days, and Klein et al. report on a very interesting new development … Continue reading Brownout: building more robust cloud applications

Consistency, Availability, and Convergence

Consistency, Availability, and Convergence - Mahajan, Alvisi, and Dahlin, 2014 We've seen in earlier papers that the classic definition of eventual consistency allows some unhelpful models such as all nodes becoming consistent due to returning a constant value. Mahajan et al. close these loopholes with a definition of convergence that matches our commonsense expectations. Then … Continue reading Consistency, Availability, and Convergence
