What are Azure Extended Zones?
Azure Extended Zones are small-footprint extensions of Azure placed in metros, industry centers, or a specific jurisdiction to serve low latency and data residency workloads. Azure Extended Zones supports virtual machines (VMs), containers, storage, and a selected set of Azure services and can run latency-sensitive and throughput-intensive applications close to end users and within approved data residency boundaries.
Azure Extended Zones are part of the Microsoft global network that provides secure, reliable, high-bandwidth connectivity between applications that run on an Azure Extended Zone close to the user. Extended Zones address low latency and data residency by bringing all the goodness of the Azure ecosystem (access, user experience, automation, security, etc.) closer to the customer or their jurisdiction. Azure customers can provision and manage their Azure Extended Zones resources, services, and workloads through the Azure portal and other essential Azure tools.
Key scenarios
The key scenarios Azure Extended Zones enable are:
Latency: users want to run their resources, for example, media editing software, remotely with low latency.
Data residency: users want their applications data to stay within a specific geography and might essentially want to host locally for various privacy, regulatory, and compliance reasons.
The following diagram shows some of the industries and use cases where Azure Extended Zones can provide benefits.
