To reduce perceived latency when accessing your skill, Alexa now provisions three AWS Lambda endpoints for your Alexa-hosted skill. Alexa provisions a Lambda endpoint for your skill in each of the following regions:
- US East (N. Virginia) us-east-1
- Europe (Ireland) eu-west-1
- US West (Oregon) us-west-2
You can provision your Amazon S3 resources in any of these regions. We recommend that you choose the region closest to your users by using the table located on this page: https://developer.amazon.com/en-US/docs/alexa/hosted-skills/build-a-skill-end-to-end-using-an-alexa-hosted-skill.html#regions
The table also determines the default hosting region that appears in the console when you create your skill.
If you'd like to select a hosting region for your Alexa-hosted skill that's different from the default, you can do so during the skill's creation. After clicking on the "Create Skill" button in your developer console, navigate to the "Hosting Region" drop-down menu in the top right corner of the screen. It's important to note that once the skill is created, the primary AWS region where your skill resources are located cannot be changed.
