According to AWS official website, “There are 77 Availability Zones across 24 regions worldwide.” The nearest geographic AWS Region to India is Mumbai (ap-south-1). Only in ‘ap-south-1’ region, there are three AWS Availability Zones (also called Subnets):
So here the question is that, “Choose Which of these three Availability Zone, so that your EC2 instance can perform better in India?”
To solve this question, We did some tests on a WordPress website for all the three Availability Zones, So that you can choose The Best AWS Region and Availability Zone for low latency in India.
Here their result is given in these three pictures:
You can clearly see in the above results, who is the winner. I mean which Availability Zone is best for India. All these tests were done on KeyCDN. Its Indian server is in Bangalore. So in the results, Bangalore is showing.
Below the final result is given for The Best Availability Zone for India:
|AP-SOUTH-1A||32.22 ms||69.72 ms||81.19 ms||260.03 ms|
|AP-SOUTH-1B||34.99 ms||70.88 ms||81.8 ms||267.75 ms|
|AP-SOUTH-1C||35.38 ms||39.95 ms||52.38 ms||357.43 ms|
So looking at these results, we can say that ‘ap-south-1a‘ is the winner in AWS Availability Zones for India. But there is not significant difference between these Availability Zones. That’s why you can choose any region for your server.
