A Globally Distributed OpenStack Swift Cluster

Several of the organizations we work with here at SwiftStack operate multiple, geographically distributed datacenters. In some cases, disaster recovery is the main driver – in other cases, applications in different datacenters all need low latency access to data. We are now working towards evolving Swift where a single cluster can be distributed over multiple, […]

Video: How OpenStack Swift Handles Hardware Failures

A couple of weeks ago we held a great meetup in San Francisco where John Dickinson, the OpenStack Swift PTL, took an in-depth look at how Swift handles hardware failures. I made John sit down and walk through it again – this time on video. It was a great overview examining the code paths for […]

Monitoring Swift With StatsD

A Swift cluster is a complicated beast—a collection of many daemons across many nodes, all working together. With so many “moving parts” it’s important to be able to tell what’s going on inside the cluster. Tracking server-level metrics like CPU utilization, load, memory consumption, disk usage and utilization, etc. is necessary, but not sufficient. We […]
