Amazon Web Services (AWS) operates one of the most comprehensive and secure global infrastructures in the world. AWS spans the globe with a robust network of 100+ Availability Zones across 30+ Regions, designed to deliver high availability, low latency, and fault tolerance.

Each Region is a separate geographic area, and within it, Availability Zones (AZs) are isolated data centers interconnected through ultra-low-latency networks. This architecture ensures seamless scalability, reliability, and disaster recovery capabilities for millions of users worldwide.

3. Data Centers

These are the actual physical buildings that house AWS servers, storage, and networking gear.

Data centers are highly secure, redundant, and maintained under strict environmental controls.

Exact numbers are not publicly detailed, but each Region can have dozens of data centers across its AZs.

4. Edge Locations

Edge Locations are data centers for content delivery (used mainly by CloudFront, Route 53, AWS Global Accelerator).

These are located closer to end users to cache data and reduce latency.

As of now, AWS has over 400+ Edge Locations globally.

5. Local Zones

A Local Zone is an extension of an AWS Region that places compute, storage, database, and other services closer to large metro areas.

Used when applications require very low latency (single-digit milliseconds).

AWS currently has 34 Local Zones in cities like Los Angeles, Dallas, and more.

6. Wavelength Zones

Wavelength Zones bring AWS services to telecom 5G networks, enabling ultra-low latency apps (e.g., AR/VR, smart cities).

AWS partners with telcos to embed compute/storage near 5G towers.

Available in select cities globally.

7. AWS Outposts

Outposts are fully managed racks of AWS infrastructure installed in your own data center.

Useful for hybrid cloud where data must remain on-premises due to regulatory or latency reasons.

8. Points of Presence (PoPs)

These include both Edge Locations and Regional Edge Caches.

Helps optimize performance of globally distributed content.
