The AWS Cloud's global infrastructure spans across regions and Availability Zones (AZs), enabling high availability and fault tolerance. Regions are geographic areas with multiple AZs, each comprising isolated data centers. AZs are interconnected via low-latency links to ensure redundancy and reliability. Edge locations facilitate content delivery through Amazon CloudFront's Content Delivery Network (CDN). With this robust infrastructure, AWS offers scalable, secure, and performant cloud services worldwide, meeting diverse business needs.
