Empirical Study of Responsiveness of AWS Regions

Overview

This is a study that aims to help you decide in which AWS region to place your server for optimum responsiveness.

Assumptions:

• You run a company website that addresses an audience spread globally but have a small budget.
• Have funds for only limited number of instances of your website & back end database.

Goals:

Decide optimum placement of an EC2 instance depending on:

• Predicted response times from users everywhere
• Presumed geographical distribution of users
• Maximum cost

Method

We launch an EC2 instance in each of the 7 AWS regions and perform HTTP requests from a slice of around 100 PlanetLab nodes distributed globally every 15min for a duration of two weeks. We then collect the data at a central point and analyze the request times to determine which AWS regions are more responsive for clients from various geographical locations.
