I keep this following list of AWS Regions up-to date for my own reference but I thought it might help others too and so I publish it here.
People often ask which region they should use. There are three main considerations that I think about when choosing a region for my application.
- Service and feature availability. Whilst a best effort is made to place all services in all regions there are differences. Some regions often get services before others although this is becoming less common. In the UK, where I am Ireland eu-west-1 tends to have services released first.
- Cost. Different regions have different costs due to various local cost like electricity.
- Latency. You should place your applications as close to your users as possible to reduce latency. There is no getting around the laws of physics.
