AWS has 30 launched regions, each with multiple Availability Zones (AZs). There are 96 AZs in AWS. Also, it has 400+ Edge locations and 13 Regional Edge Caches. In addition, they are increasing their Regions and AZs.
Regions
The region is a physical location around the world where we cluster data centers.
We call each group of logical data centers an Availability Zone. Each AWS Region consists of a minimum of three, isolated and physically separate AZs within a geographic area. Examples of regions are the Asia Pacific (Mumbai) Region - ap-south-1,** US East (Northern Virginia) Region - us-east-1, and so on.**
Availability Zones
An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region.
AZs are physically separated by a meaningful distance, many kilometers, from any other AZ, although all are within 100 km (60 miles) of each other. Examples of AZs:In ap-south-1, we have 3 AZs - ap-south-1a, ap-south-1b, and ap-south-1c.In us-east-1, we have 6 AZs - us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1e, and us-east-1f.
Services
AWS offers a broad set of global cloud-based products including computing, storage, database, analytics, networking, machine learning, and AI, mobile, developer tools, IoT, security, enterprise applications, and much more.
A few examples of services are Amazon Elastic Compute Cloud (EC2), Amazon Elastic Container Registry (ECR), Amazon Simple Storage Service (S3), and so on.
Edge locations
Edge locations are AWS data centers designed to deliver services with the lowest latency possible.
Amazon has dozens of these data centers spread across the world. They're closer to users than Regions or AZs, often in major cities, so responses can be fast and snappy.
Local Zones
AWS Local Zones place computing, storage, database, and other select AWS services closer to end-users.
With AWS Local Zones, you can easily run highly-demanding applications that require single-digit millisecond latencies for your end-users such as media & entertainment content creation, real-time gaming, reservoir simulations, electronic design automation, and machine learning.
Wavelength
AWS Wavelength enables developers to build applications that deliver single-digit millisecond latencies to mobile devices and end-users.
Outposts
AWS Outposts bring native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility.
You can use the same AWS APIs, tools, and infrastructure across on-premises and the AWS cloud to deliver a truly consistent hybrid experience.
