AWS Global Infrastructure: Regions

If you ask me a simple question what is the heart and soul of AWS or Amazon Web Services.Then I do have a simple answer to that and it is its global infrastructure.

Now what exactly is the AWS global infrastructure?

AWS global infra is actually built around regions and availability zones and in AWS world it is called AZs. Now you might ask what is the difference between a region and an availability zone.

Region: is nothing but a geographical area or metropolitan area.It could be like US-East, US-West, Asia Pacific or APAC, Europe …

And what is Availability Zone?

Availability Zone (AZ): in simple terms it is a data centre or collection of different data centres and please note each region consists of 2 or more Availability Zones

AWS global infra span across 18 geographic locations and 55 availability zones and there are plans for 12 new AZs and 4 new regions (Bahrain, Cape Town, Hong Kong and Milan).

So it appears is already planning to build twelve new Availability Zones and four new regions.

I would say our data region or AWS region provides multiple physically separated and isolated Availability Zones AZs which are connected with low latency high throughput and high redundant networking.

And how does it look like it looks like this.

So this is the map of the AWS global infrastructure.Now if you see here a few if I highlighted a bit you can see that there are different orange circles and there are some green circles.

Now what exactly are the orange circles the orange circles indicate the existing regions. And that is a small number in that region. So that number indicates the availability zones.

So if I look at this it shows that this region has three Availability Zones in it.

And now these green circles these green circles indicate the new regions that would be coming up and that would be coming up in near future I would say so folks I think now you would be much more confident with regions and Availability Zones again regions as nothing but geographical regions or geographical area or metropolitan area and Availability Zones actually map to the different data centres that are available in that region.
