Global Infrastructure in AWS(Amazon Web Services)
In this article,we will see Global Infrastructure in AWS(Amazon Web Services).
The AWS global infrastructure is built around Regions and Availability Zones.
The AWS Cloud operates 69 Availability Zones within 22 geographic Regions around the world, with announced plans for 9 more Availability Zones and three more Regions in Cape Town, Jakarta, and Milan.
We can see the above world map.
Blue color circles represent Region and Red color circle represents upcoming region across the world.
What is the Region?
Regions are nothing but physical location or geographic location across the world.
Each region is a separate geographic area.
Each region has multiple isolated locations known as availability zones.
Each Amazon EC2 region is designed completely isolated from other Amazon EC2 region.
Availability Zones
Availability zones consists of one or more discrete data centres, each with redundant power, networking and connectivity
Each availability zone completely isolated from each other.
Availability Zones are clustered with each other.
An Availability zone combination of one or more data centers.
AZ’s are physically separated and isolated and are connected with low latency, high throughput and highly redundant networking.
When you launch an instance, you can select an Availability Zone or let us choose one for you.
If you distribute your instances across multiple Availability Zones and one instance fails, you can design your application so that an instance in another Availability Zone can handle request.
Data Centers
A data center is a location where actual physical data resides.
A single or couple of data centers are clubbed in to on availability zone.
Edge Locations
AWS has more points of presence with edge locations, smaller locations that cache data and used through AWS cloud front service.
Used by content delivery network(Cloud Watch).
There are currently 40 edge locations with more being added each month. They are located in most the major cities around the world and are used by CloudFront (CDN) to distribute content nearer to the end user.
You can use the Amazon EC2 console to determine which Regions and Availability Zones are available for your account.
Logging to AWS Management Console
Go to AWS Management Console by using below link.
https://aws.amazon.com/console/
Login using username & password and click on sign in.
We can see the AWS Management Console Dashboard.
In the AWS Management Console, we can see 18 Regions across the world.
In the above image we can see only 18 regions out 22 regions across the word.
Out of 18 regions 16 are regions are enabled by default and 2 are regions are Disabled by default.

Change the region
Here, we can see the “Mumbai” is my current region.
I want to change my current region “Mumbai” to another region “Singapore”.
Go to region tab “Mumbai” and click on there we can see 18 regions and select required region ( I am choosing the Singapore region) then click on that.
Now, the region has been changed, there we can see only location name “Singapore”.
Disabled by default regions
- Asia Pacific (Hong Kong)
- Middle East (Bahrain)
These two regions are disabled by default.
We need to enable and disable the regions manually.
Administrators can enable and disable these regions.
You cannot enable or disable regions that are enabled by default. You can only include regions that are disabled by default. For more information.

Here, we can see all the Regions and Availability Zones.
