AWS Global Network is a collection of highly available and secure cloud infrastructure services that enable AWS customers to run their applications and workloads around the world.
The AWS Global Network:
- is a collection of interconnected data centers and network infrastructure that spans the globe. It provides high-performance, low-latency, and secure access to AWS services and resources for customers and end-users
- is constantly expanding and improving to meet the needs of customers and provide the best possible cloud computing experience
AWS Global Network consists of three main components: AWS Regions, AWS Availability Zones, and AWS Edge Locations.
AWS Regions
AWS Regions are geographic areas where AWS operates multiple data centers that host AWS services. Each region is designed to be isolated from other regions, ensuring fault tolerance and data sovereignty. AWS currently has 25 regions and plans to launch 20 more in the near future.
AWS Availability Zones
AWS Availability Zones are physically separate locations within each region that have independent power, cooling, and network connectivity. Each availability zone can host multiple AWS services and resources, such as EC2 instances, S3 buckets, and RDS databases.
Availability zones provide high availability and redundancy for customers who want to run their applications across multiple locations within a region.
AWS Edge Locations
AWS Edge Locations are points of presence that deliver AWS services closer to end users, reducing latency and improving performance. AWS Edge Locations include CloudFront edge locations, which cache and serve static and dynamic web content; Lambda@Edge locations, which run serverless functions at the edge; and WAF and Shield edge locations, which provide web application firewall and DDoS protection services. AWS has over 200 edge locations in 77 cities across 37 countries.
