Expanding the number of data centers in different regions is crucial for improving cloud service performance and meeting local regulations. By situating data centers closer to users, we can reduce latency, which means faster access to data and more responsive applications. This local presence also helps cloud providers comply with data residency laws, like GDPR and CCPA, ensuring customer data is handled according to legal requirements. Overall, having more regional data centers builds trust with users and enhances the reliability of cloud services, allowing businesses to operate more efficiently across various locations.
