Let's supposed I am running an API that are available via different endpoints, each being deploy in different data centres. For instance:
ny.api.example.com(New York, US data centre)ln.api.example.com(London, UK data centre)sg.api.example.com(Singapore data centre)
I want to use a service like Cedexis Openmix to point DNS requests for api.example.com to the endpoint that would provide the quickest response time. (E.g. a request from Paris would resolve to ln.api.example.com) Therefore, I need some data about the latency of requests to each endpoint.
Most of the traffic to our API will be from other enterprise applications, and so are likely to originate from major AWS data centres. So is there a service that measures the response time / latency from different AWS regions / availability zones to different endpoints?
There are several services that measures latency from my browser to different AWS availability zones, such as CloudHarmony, CloudPing and CloudWatch. I am looking for something similar, but the other way round - from AWS availability zones to a specific endpoint.
You could use AWS route53 health check to your end point. Or you could predict the latency between to aws regions from https://www.cloudping.co/
