High Availability and Cloudy Problems

Tuesday, September 21, 2010

VoltDB, like many distributed systems, achieves high availability through redundant processing nodes. VoltDB calls this K-Safety. Essentially, the distributed system can answer any request at at least K+1 servers, so it can tolerate at least K hardware failures. The operator specifies the value of K that they find is the best tradeoff between failure, robustness and cost. Other systems use the terms “replica set” to describe similar functionality.


Let’s talk about EC2-style clouds that provide you with a virtualized server at an hourly cost.

VoltDB in-memory database achieves best-in-class results, running in the cloud, on the YCSB Benchmark

Wednesday, May 7, 2014

The development team at VoltDB recently ran VoltDB v4.2 against the Yahoo Cloud Serving Benchmark (YCSB), an industry-standard performance benchmark for cloud databases. We ran our test on as realistic a cluster setup as possible: commodity hardware that we could easily book as spot instances on EC2, with features like durability and high availability enabled. And we ran a varied mix of workloads with realistically sized, 1 KB rows, rather than focusing on a specific, overly favorable use case.
