In 2006, Amazon Web Services (AWS) pioneered cloud computing as we know it today. And with about 34% of the market share, Amazon Web Services remains the largest cloud infrastructure provider today, followed by Microsoft Azure and Google Cloud Platform (GCP).
AWS is a Cloud Service Provider (CSP). That means AWS builds, maintains, and continually improves multiple data centers worldwide and then rents the computing infrastructure out to other companies as needed, over the Internet.
For organizations, this is often an effective way to avoid purchasing, installing, maintaining, and upgrading their own data centers, which can be expensive and time-consuming.
In a nutshell, that’s how the cloud works — except there’s no cloud, just lots of third-party data centers and managed IT infrastructure. Here’s what we mean.

What Is A Data Center?
A data center is a physical facility that stores computing machines along with the hardware that supports their operation. This location houses the computing infrastructure IT systems need, like servers, network equipment, and data storage drives.
A modern data center is the physical location that stores your company’s digital data.
An AWS Data Center provides scalable computing power that multiple businesses can access anytime, anywhere over a network. Instead of building and maintaining their own data centers, businesses pay a monthly fee to access this global network of AWS data center infrastructure. In essence, this is what’s referred to as the Cloud.
AWS provides over 200 services and products. And virtually all AWS data centers support multiple cloud services, including compute, storage, networking, database, enterprise applications, security, analytics, Machine Learning (ML), Artificial Intelligence (AI), mobile, developer tools, Internet of Things (IoT), and more. In essence, these are the services that support Cloud Computing.
How many data centers does AWS have?
AWS has over 100 data centers in different parts of the world. Each data center can have as many as 50,000 servers, and as of 2014, AWS had over 1.4 million servers in all its data centers.
AWS data centers are spread across 31 AWS Regions, 99 Availability Zones (AZ), 245 countries and territories, over 400 Edge Locations, 34 Local Zones, and 115 Direct Connect Locations. The cloud provider plans to launch another 5 Regions and 15 Availability Zones soon.
You might be wondering what AWS Regions and AZs mean.
What Is An AWS Region?
An AWS Region is a geographic area anywhere in the world where the company has a cluster of data centers. The 31 launched AWS Regions are available in all continents except Antarctica. Most AWS Regions are in North America, Europe, and Southeast Asia.
The North Virginia AWS Region was the first to launch in 2006 and comprises the most Availability Zones to date (6).
What Is An AWS Availability Zone?
An AWS Availability Zone refers to one or more data centers that are physically separate and have independent power and cooling, yet are linked logically. This design adds layers of resilience (durability, security, and reliability) to the AWS cloud infrastructure.
For example, AWS stores your data in multiple Availability Zones in the same or different AWS Regions so it remains available even if the primary data center is affected by an outage. This is perfect for backup and disaster recovery purposes.
A single AWS Region comprises multiple, autonomous, and geographically distinct AZs spread across a geographic area.
What is the difference between an Availability Zone and Local Zone in AWS?
The differences between Availability Zones, Local Zones, Wavelengths, and Outposts are subtle but important.
- AWS Availability Zone – A group of logically connected but geographically separated data centers.
- AWS Local Zone – An extension of an AWS Region where you can run selected services close to your end users or on-premises installations to reduce latency.
- AWS Wavelength – Supports ultra-low-latency mobile edge computing by providing compute, storage, and networking services within 5G networks of communications service providers (CSPs).
- AWS OutPost – Delivers native AWS operating models, services, and infrastructure to virtually any on-premises facility, data center, or co-location space. Provides a consistent hybrid experience across on-premises and AWS cloud services, including APIs and tools.
- AWS Edge Location – A cluster of data centers designed to provide fast access to data from any location by keeping cache copies of that data closest to the end user. They include AWS Local Zones, Regional Edge Caches, and Edge lkocations
- AWS Regional Edge Caches – These are AWS CloudFront (the low-latency content delivery network (CDN) service) locations in close proximity to your viewers — anywhere in the world. These are positioned between your origin server and related POPs, which are the global edge locations serving content directly to your viewers.
Speaking of positioning, here are details about where AWS has data centers across the globe.
Where Are AWS Data Centers Located And Why?
AWS provides data centers in the geographic regions of North America (US and Canada), Europe (Germany, UK, France, Ireland, Sweden, Italy, Switzerland, and Spain), Asia Pacific (China, Japan, India, Indonesia, and Singapore), Middle East (Bahrain, UAE, and Israel), Africa (South Africa), South America (Brazil), and Australia/New Zealand.
There are multiple edge locations and regional edge caches at each of these locations.
In addition, each AWS Region or AZ in any of these locations offers a different price for compute, storage, networking, and other AWS services.
It’s for that reason that you’ll want to be attentive when deciding where to deploy your applications on the AWS cloud. For example, the US East (Ohio) Region tends to offer the lowest AWS service prices.
Here are the AWS data center locations in terms of AWS Regions and Availability Zones.
North American locations

Over To You
AWS plans to expand its data center network to support the growing demand for cloud computing as more organizations migrate to the cloud.
But here’s the thing.
AWS infrastructure costs can be hard to track, analyze, and act on. It is especially difficult if you have workloads or applications running in different regions, availability zones, etc. The most common culprits behind surprise AWS bills are data transfer charges and complex multi-cloud pricing.

What is the difference between a data center and the cloud?
The cloud is a distributed network of remote servers accessible on an as-needed basis over the Internet, while a data center is a centralized physical location for storing, processing, and distributing data.
Also, while owning a data center requires you to manage your own infrastructure, the cloud service provider manages the infrastructure on your behalf in the cloud.
