Influence on the chosen AWS region in performance

Logically, comparing two similar infrastructures, it is expected that the closer to the request user respond more quickly.

For web applications in AWS in general (not being real time), the difference between regions is significant?

I ask because I would like to use Cloudfoundry to deploy my apps, but I only see it available via the US-East region. I’m afraid my application will be slow because it would be restricted to users from Brazil.

It depends a lot on your application, in any case follows here some resources to better evaluate:

  • You can use the http://cloudping.info to estimate the latency of your local network to the AWS regions.

  • In addition to latency, consider also that the price and availability of services is different by region.

  • With Amazon Cloudfront you can get the best price and the best latency. Consider using the American region and global focal points for content distribution.

  • I appreciate the answer but I wanted something more comprehensive about the influence of latency on the performance of the application. Is it just adding latency to the response time of every request? Times two because the request has to go to the user and go back to the server?

  • It’s actually a little more complicated, because it depends a lot on the application and how it behaves. The number of requests, and the distribution of response times, influence a lot. If you want something deeper, I recommend Brendan Gregg’s book and lectures
