What is AWS Global Infrastructure?
AWS is able to offer services that are fast, resilient, and accessible from anywhere in the world. This is possible thanks to its global infrastructure — one of Amazon Web Services’ greatest advantages. The following image helps illustrate how it works.
Regions
These are independent geographic regions that contain multiple Availability Zones (AZs). This way, if one region experiences an issue, it won’t affect the others. In the image, we have an example: us-east-2 - US East (Ohio).
Examples:
- US East (N. Virginia) – us-east-1
- South America (São Paulo) – sa-east-1
- Europe (Ireland) – eu-west-1
There are regions all over the world — the image only shows a few examples.
Choosing the right region is important to reduce latency. For instance, if your customers are in Brazil, it’s a good idea to deploy your application in the Brazil region. In this case, you can use sa-east-1.
Availability Zone (AZ)
Each region has at least two AZs, which are physically separated data centers but interconnected with low latency. This enables high availability and fault tolerance. In the image, we have three AZs.
If one AZ becomes unavailable — due to a disaster, for example — the other AZs remain operational, keeping your application available and ensuring high availability and fault tolerance.
Local Zones
They are extensions of an AWS Region that are close to large population centers and industrial hubs.
Wavelength Zones
AWS Wavelength enables developers to build applications that require edge computing infrastructure to deliver low latency to mobile devices and end users or increase the resiliency of their existing edge applications.
Outposts
They bring AWS infrastructure and services closer to the edge or on-premises locations.
For example, a data center in a small city that is not part of a Local Zone — or even an on-premises deployment inside a customer’s facility.
This helps reduce latency even further.
Why AWS Global Infrastructure Matters?
🌍 Global Availability
⚡ Low Latency
🔁 Resilience & Redundancy
🧩 On-demand Scalability
🛡️ Regional Compliance & Security
Conclusion
AWS is not just a collection of cloud services — it’s a powerful and intelligent global infrastructure that enables applications to scale worldwide with security, reliability, and performance.
