What is AWS Global Infrastructure?

The AWS Global Infrastructure is a vast network of data centers and resources strategically located worldwide to provide cloud services. The infrastructure comprises multiple interconnected components, such as Regions, Availability Zones, Local Zones, and Wavelength Zones.

AWS Global Infrastructure’s main component is data centers called Availability Zones (AZ). AZs are isolated locations within AWS Regions. The AWS Global Infrastructure Map includes 102 Availability Zones spread across 32 geographic regions globally. Moreover, plans are underway to expand with an additional 12 Availability Zones and 4 more AWS Regions, covering countries like Canada, Malaysia, New Zealand, and Thailand.


What are the Key Components of AWS Global Infrastructure?

The AWS Global Infrastructure represents a highly distributed and robust ecosystem of data centers, ensuring global coverage, reliability, and performance for a wide array of cloud-based services and applications. Here are the 6 components of AWS Global Infrastructure:


  • Regions
  • Availability Zones (AZs)
  • Local Zones
  • Edge Locations
  • AWS Regional Edge Caches
  • Wavelength Zones



AWS Regions

An AWS Region is a distinct geographical area worldwide where a collection of data centers is clustered. This model incorporates multiple Availability Zones and physically and logically separate logical data center groups. Each AWS Region comprises at least three Availability Zones, ensuring geographic redundancy and high availability.

AWS Regions and Availability Zones are not the same. AWS Regions are the larger geographical areas where data centers are located, while Availability Zones are subsets within those regions. We will discuss AZs intensely in the next part.

AWS operates in several geographic regions, including North America, South America, Europe, China, Asia Pacific, South Africa, and the Middle East.


AWS Availability Zones

People often refer to Availability Zones (AZs) in AWS as data center facilities. Each Availability Zone is a physically separated data center with power and infrastructure. AWS has strategically designed these Availability Zones to provide redundancy and resiliency for applications and services.

AWS Availability Zones have their own power, cooling, and networking infrastructure. Deploying resources across multiple Availability Zones ensures that if one AZ experiences issues or downtime, it enables the others to continue operating, thereby enhancing the overall resilience of applications hosted on the AWS platform.

Here is the complete list of AWS data center locations in all regions:


  • Europe / Middle East / Africa
  • 11 Geographic Regions
  • 33 Availability Zones
  • 39 Edge Network locations
  • 2 Regional Edge Cache locations
  • Availability Zones: Bahrain (3), Cape Town (3), Frankfurt (3), Ireland (3), London (3), Milan (3), Paris (3), Spain (3), Stockholm (3), Zurich (3), and UAE (3)


  • North America
  • 7 Geographic Regions
  • 25 Availability Zones
  • 44 Edge Network locations
  • 2 Regional Edge Cache locations
  • Availability Zones: N. Virginia (6), Ohio (3), N. California (3), Oregon (4), US-East (3), US-West (3), Central (3)


  • South America
  • 1 Geographic Regions
  • 3 Availability Zones (in São Paulo)
  • 4 Edge Network locations
  • 1 Regional Edge Cache locations
  • Asia Pacific and China
  • 12 Geographic Regions
  • 38 Availability Zones
  • 34 Edge Network locations
  • 5 Regional Edge Cache locations


AWS Local Zones

AWS Local Zones are a part of the AWS Global infrastructure that brings cloud services locally to specific areas with a high concentration of users and applications. These Local Zones are a subset of AWS Availability Zones near specific metropolitan areas.

Local Zones allow customers to deploy applications that require low latency to end-users or specific resources in those geographic areas. They are handy for applications that require real-time processing, such as gaming, interactive multimedia, and financial services, where reducing latency is critical for a seamless user experience.


AWS Edge Locations

AWS Edge Locations are endpoints for Amazon Web Services’ CloudFront service. They are strategically distributed data centers situated in various areas around the world. These Edge Locations act as caching servers that store copies of frequently accessed content, such as images, videos, web pages, and other static files, closer to the end users.

The Edge Location closest to the client receives requests for content distributed via CloudFront. This reduces latency and improves the overall performance of the application or website if the content already exists at that Edge Location. If the content still needs to be cached, the Edge Location retrieves it from the origin server (such as an Amazon S3 bucket or a custom origin) and caches it for subsequent requests.


AWS Regional Edge Caches

Like edge locations, Regional Edge Caches are CloudFront service sites strategically placed worldwide near your viewers. They deliver content directly to viewers between your origin server and global edge locations.

Regional edge caches assist with many sorts of material, especially content that becomes less popular over time. Examples are user-generated material, e-commerce assets, news, and other content that may rapidly gain popularity.


Wavelength Zones

AWS Wavelength is an Amazon Web Services (AWS) service that brings cloud services to the edge of 5G networks. It supports real-time gaming, augmented reality (AR), virtual reality (VR), video streaming, and other applications that require ultra-low latency and high bandwidth connectivity.

A Wavelength Zone is a specialized infrastructure deployment within a data center run by a telecommunications provider.

These zones are strategically placed near 5G base stations, directly connecting the AWS resources and the 5G network. The proximity minimizes latency for applications requiring instant responses.


What are the 6 benefits of AWS Global Infrastructure?

The AWS Global Infrastructure offers 6 key benefits to businesses and organizations that leverage its services, as mentioned on the AWS website: security, availability, performance, scalability, flexibility, and global footprint.


Security: AWS offers robust security measures, including encryption and constant monitoring. You maintain control over your data with encryption, movement, and retention options.


Availability: AWS ensures the utmost network availability among cloud providers. Each region is isolated and divided into multiple Availability Zones (AZs). If one AZ experiences an issue, other AZs can continue to operate without interruption.


Performance: Low latency, minimal packet loss, and high network quality are all characteristics of AWS Global Infrastructure.


Scalability: AWS enables flexible scaling of resources, eliminating over-provisioning. You can instantly adjust resources based on business needs, rapidly deploying hundreds or thousands of servers.


Flexibility: You can choose how and where to run workloads, utilizing the same network, control plane, APIs, and services. Options include global AWS Regions, AWS Local Zones, AWS Wavelength for low latency, and AWS Outposts for on-premises deployment.


Global Footprint: AWS has an extensive global infrastructure presence. You can select technology infrastructure close to your intended users, ensuring ideal assistance for a wide range of applications, from high throughput to low-latency performance.
