Assess the Regions based on whether they have the features and services you need to manage your workload and are compliant. You can find this information on the AWS Regional Services List website. Plus, if your workload has specific requirements, you should also determine whether the available versions and services offer the required features or not. Also, don’t forget to test the latency between the base location of your users and the AWS Region you’re considering. To compare the costs associated with the workload on different regions, use the AWS Pricing Calculator.
