What is AWS? Decoding why it attracts so much attention from businesses

AWS is currently the leading cloud computing platform, offering a comprehensive suite of solutions that include compute services, storage, databases, big data processing, and artificial intelligence. The platform is designed to meet the needs of businesses for secure, stable data operations, storage, and management in the digital era.

In the content below, Homenest Software will walk you through AWS—from its core concepts to the key benefits and essential services it provides.

What is AWS?

AWS (Amazon Web Services) is a cloud computing platform operated by Amazon, offering more than 175 services that cover almost every business need—such as virtual servers, data storage, databases, AI, machine learning, and IoT.

One of AWS’s standout strengths is its global scalability. With a vast network of data centers worldwide, businesses can deploy applications in any region without geographic limitations.

As a result, products and services can easily reach international customers with high speed, stable performance, and exceptional flexibility.

How does AWS work?

AWS operates on a multi-layered infrastructure consisting of Regions, Availability Zones, and Edge Locations. These three components work together to ensure high speed, high availability, and globally stable performance.

Region

A Region is a large geographical area where AWS builds multiple data centers. Examples include Singapore, Tokyo, Paris, and Ohio.

Each Region operates completely independently and includes:

• data storage and processing systems

• networking and security

• power supply and backup systems

• cooling, monitoring, and operations

Thanks to this separation, businesses can choose the Region closest to their customers for faster access, or select specific Regions to meet legal or compliance requirements (such as storing data within the EU).

Availability Zone (AZ)

Each Region is divided into 2–6 Availability Zones, and each AZ is its own standalone data center. AZs are placed far enough apart to avoid being affected by the same incident (power outage, fire, flooding…) yet remain connected through high-speed networks.

AZs are designed to:

• Ensure high availability

• Support multi-AZ applications to prevent downtime.

• enable automatic failover when one AZ encounters an issue

Example: The Singapore Region (ap-southeast-1) has 3 AZs: 1a, 1b – 1c.
When businesses deploy applications across multiple AZs, their systems continue running even if one AZ fails.

Edge Location

Edge Locations are smaller server sites distributed across the world and positioned closest to users. They are mainly used for the Amazon CloudFront (CDN) content delivery service.

Roles of Edge Locations:

• cache static content such as images, videos, CSS, and JS

• shorten the distance between the application and end-users

• reduce latency

• improve global website or API loading speed

AWS currently has 600+ Edge Locations, helping applications load quickly even when users are far from the primary Region.
