What services are provided by AWS's global network infrastructure?

Last updated on 

Amazon Web Services (AWS) operates a global network infrastructure that plays a crucial role in delivering various cloud services to customers worldwide. The AWS global network is designed for high availability, low-latency, and scalability. Here are the key services provided by AWS's global network infrastructure:

  1. Amazon Elastic Compute Cloud (EC2):
    • AWS's compute service, EC2, is distributed across multiple Availability Zones (AZs) within each AWS region. These AZs are connected by a highly redundant and low-latency network to ensure fault tolerance and high availability.
  2. Amazon Virtual Private Cloud (VPC):
    • VPC allows users to create isolated virtual networks within the AWS cloud. The AWS global network provides the underlying infrastructure for VPC, enabling users to connect their VPCs across regions and create complex networking architectures.
  3. Amazon CloudFront:
    • AWS's content delivery network (CDN) service, CloudFront, leverages the global network infrastructure to distribute content to edge locations strategically placed around the world. This reduces latency and enhances the performance of web applications and content delivery.
  4. Amazon Route 53:
    • AWS's domain name system (DNS) service, Route 53, is globally distributed, providing low-latency DNS resolution. It uses a network of DNS servers located worldwide to route end-user requests to the appropriate resources.
  5. AWS Direct Connect:
    • Direct Connect allows users to establish dedicated network connections from their on-premises data centers to AWS. This service is available in multiple global locations, providing private, high-bandwidth connectivity to AWS resources.
  6. AWS Global Accelerator:
    • Global Accelerator is a service that uses the AWS global network to route traffic over the AWS backbone to optimize for global application performance. It provides static IP addresses and directs traffic over the optimal AWS network paths.
  7. AWS Transit Gateway:
    • Transit Gateway simplifies the connectivity between multiple VPCs and on-premises networks. It operates at the network level and is integrated into the global AWS network to facilitate scalable and efficient network architectures.
  8. AWS Direct Connect Gateway:
    • Direct Connect Gateway enables users to connect their Direct Connect connections to multiple VPCs across different regions. This allows for a centralized and simplified network connectivity setup.
  9. AWS Global Network Accelerator:
    • This service is designed to improve the availability and performance of applications for global users. It uses Anycast IP addresses to route traffic over the AWS global network to the optimal AWS endpoint based on health, geography, and routing policies.
  10. AWS Wavelength:
    • Wavelength is designed for applications that require ultra-low latency. It brings AWS compute and storage services to the edge of telecommunications networks, allowing for faster and more responsive applications.

AWS's global network infrastructure provides a robust foundation for delivering a wide range of cloud services with a focus on reliability, low-latency, and scalability across the globe. The interconnected nature of these services allows customers to build and deploy applications that meet their specific requirements for performance and availability.
