The first step in using Windows Azure should be to create an affinity group affinity groups

Windows Azure currently has eight big data centers worldwide (US West, US east, North Central US, South Central US, Nordic, Western Europe, East Asia, South Asia). There are two data centers in North and south of China. Each data center consists of several "containers", the inside of which is a cluster (cluster) and a rack (rack). Each container has a specific service, such as compute and storage, SQL database and service bus, access control services (an Access control service), and so on.

Not only do we create managed services and storage accounts in the same datacenter, it's a good idea to put the managed services and storage accounts on the same cluster/rack, which minimizes network latency.

The role of an affinity group is to ensure that both left and right resources within the same affinity group are deployed on tightly connected physical devices, ensuring minimal network latency, maximum bandwidth, and best performance.
