Summary
Shanghai Blue Cloud Technology (Azure China)
hosting cloud
Shanghai Blue Cloud Technology Co., Ltd (BLUECLOUD) operates the network
behind Microsoft Azure's China regions, which are run locally under a Chinese
partner rather than by Microsoft directly.
What it's used for
- Public cloud hosting and compute for Azure customers within China (Azure China / China East and related regions).
Notable
- This is a cloud/hosting network, not a consumer mobile carrier — addresses here front datacenter and cloud workloads, not end-user handsets.
- China's regulatory model requires foreign cloud providers to operate through a domestic partner, which is why Azure China sits under a separate operator.
Interesting
- Running Azure in China through a local entity keeps the service inside China's regulatory and data-residency framework, isolated from Microsoft's global cloud ASNs.
