Multi-region Object Storage – 4 Options for SwiftStack (with OpenStack Swift)
Multi-region SwiftStack deployments with OpenStack Swift offer big advantages to keep data online utilizing multiple data centers. I met up with John Dickinson, the Swift Project Technical Lead and Dir. of Technology at SwiftStack to discuss the options for multi-region data center configurations.
There are 4 basic configuration options. Two using replicas and two using erasure encoding strategies.
Replicas: Algorithmic Placement
Replicas: Deterministic Placement
EC: In-Region Rebuild
EC: Capacity Optimized
All of these policies can be utilized within the same cluster on the same hardware. So different data sets can utilize different policies depending on the use case.
