Distance between Azure Zones

Question

Hello,

AWS is clear and provide the minimum distance between 2 zones "although all are within 100 km (60 miles) of each other.": https://aws.amazon.com/about-aws/global-infrastructure/regions_az/

Regarding Azure, I couldn't find the any information about it. How to advise clients when they are multi-cloud ?

Regards

Answer 1

Hi, Welcome to Microsoft Q&A community forum!
Many Azure regions provide availability zones, which are separated groups of datacenters within a region. Availability zones are close enough to have low-latency connections to other availability zones. They're connected by a high-performance network with a round-trip latency of less than 2ms. However, availability zones are far enough apart to reduce the likelihood that more than one will be affected by local outages or weather
But the actual distance between datacenters in availability zones is not defined and may vary. MS does not provide this type of information, but guarantees that a problem with one of the datacenters will not affect the other datacenters in the availability zone. If you have stringent parameters, you can consider using a different region for your disaster recovery
Azure strives to ensure a minimum distance of 300 miles (483 kilometers) between datacenters in enabled regions, although it isn't possible across all geographies.
