A cloud region is a geographic area containing multiple independent availability zones. Cloud providers distribute their infrastructure across regions to improve performance, comply with data regulations, and ensure resilience. Users choose regions based on proximity to customers, required latency, and compliance needs.
Why it matters
Selecting the right region affects latency, data residency, cost, and disaster recovery strategies. Deploying across multiple regions can improve global performance and redundancy.
Examples
Deploying a web application to us-east-1 or storing analytics data in eu-central-1. Lessons like Regions and Availability Zones provide deep insight.
