A cloud region refers to a specific geographical location where cloud service providers, such as Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure, host their infrastructure. These regions consist of multiple, isolated, and physically separate data centers known as availability zones, offering users the ability to run their applications and store data in close proximity to their end-users. This geographical distribution helps in reducing latency, improving application performance, and ensuring data sovereignty compliance by adhering to local regulatory requirements. Cloud regions also play a crucial role in disaster recovery and data redundancy strategies, as users can deploy their applications across multiple regions to enhance availability and protect against region-specific failures. Each cloud provider offers a global network of regions, allowing users to select the most appropriate location(s) for their services based on factors such as cost, compliance, and connectivity.
