I am located in Asia-Pacific(Mumbai) region. I have S3 bucket abc.
I have a image A.png with full public read access.

So now URL i can use to access it from internet as suggested by AWS in AWS console is:

I can also access Image from Following URLs as well:

Now AWS Docs here Provides following info:
enter image description here

If my bucket is in US-East(N.Virginia), the URL format provided is

So my question here is, Do i need to keep in mind about the URL patterns while using public URLs in my applications?
Why AWS is giving different URL patterns instead of standardising one format for virtual-hosted-style and one format for path-style?

Please let me know if i misunderstood any technical details here.

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

You can get the list of endpoints from here:

https://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

You should use website endpoint & rest endpoint as per actual requirement and use cases.

Please find the details here:

https://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint.
