This document summarizes a presentation by Joe Arnold, CEO of SwiftStack Inc., about building applications with OpenStack Swift. The presentation discusses how Swift is well-suited for web and mobile applications due to its HTTP interface and ability to scale to support massive numbers of users. It also notes that Swift enables infrastructure as a service by providing multi-tenancy, scaling out capacity efficiently, and improving operational efficiencies.

Add Proxy Nodes A hash ring is

Swift Scales to Massive # of users
Swift uses shared-nothing architecture
1. account data
2. object data
3. All data distributed via hash
ring
Simple mechanisms proven at scale
1. Whole files on disk
2. Routed networking (Layer 3 networks)
3. Proven techniques with HTTP for transport
4. Proven techniques with rsync for
replication
