Tag: addresses

I look at Google Cloud and AWS. If you essentially select "Reserve static IP address," you must specify a region such as us-east-1, and so on. I understand that regions are different data centers, but I'm not there. Check what the process is for IP addresses used in terms of domain names.

Suppose you have a website like mywebsite.com, I'm wondering how this is assigned to a static IP address, or whether it needs to be static and can be dynamic instead.

I imagine that there is a 1-1 mapping of the IP address to the domain name. So mywebsite.com may be associated with the globally unique public static IP of 123123123123and then this will be distributed across multiple servers for load-balancing.

What is lacking in this understanding, however, is the area in which regions are deployed. When I want to "support different regions," requests are processed faster. I could imagine servers running in a specific region. These servers all handle the request for the domain mywebsite.com, But what I do not understand is if there are any multiple IP addresses (static IP addresses I guess) all mappings to the same domainhow the thing selects which IP address to use. I wonder if it's physically based on the interconnected systems. So my request to my laptop mywebsite.com go on my LAN to the WAN in the nearest region and find out that "Oh, I have to go 123.123.123.123 for the Eastern region, not the 123.123.123.124, which stands for the West region." Then the request is processed by the local servers and so on. I get the end.

What I miss is how to select the appropriate IP address if a domain has multiple IP addresses assigned to it to support the optimization of multiple regions.
