What defines a region in cloud services?

A region in cloud services is defined as a unique geographical area that contains isolated infrastructure. This means that within each region, the data centers and their associated resources are physically distinct from those in other regions. This isolation is essential for providing redundancy and disaster recovery capabilities, as well as ensuring compliance with local regulations that may govern data residency and privacy.

Regions allow cloud providers to deploy services in various locations around the world, enabling customers to choose where their data is stored and processed. This can improve latency by placing services closer to end users and enhance service availability through geographical dispersion. Thus, the concept of regions is foundational in cloud architecture, as it emphasizes both the performance and legal considerations of deploying applications and managing resources in the cloud.
