Azure Geolocation and Affinity Groups
Windows Azure can be deployed in any of six data centers around the world – South Central US, North Central US, West Europe, East Europe, East Asia, Southeast Asia. ( Microsoft has pledged to increase the number of gelocated data centers going forward. Developers should consider geolocation for any of the following reasons:
- Performance — The closer a data center is located to a user the more responsive an application will be for that user. Developers should also consider the Windows Azure CDN which can serve an apps content from the the closest of 18 geographical ‘edge’ locations.
- Legal — Legal requirements vary across the world and often pertain to the location in which the application is located
- Business continuity/backup — To minimize the risk of an outage due to severe network outage or natural disaster, applications can be spread out across multiple locations.
