Alexa: AWS regions for Lambda functions

Playing around with Alexa Skills Kit. I was having an issue where my lambda function was not being triggered by Alexa. The lambda function itself works fine when testing within AWS Console. The issue turns out related to the region where my lambda function was created.

For custom skills, Lambda functions can be hosted in one of these regions:

• Asia Pacific (Tokyo)
• EU (Ireland)
• US East (N. Virginia)
• US West (Oregon)

For smart home skill:

• N.Virginia for English (US) or English (CA) skills
• EU (Ireland) region for English (UK), English (IN), German or French (FR) skills
• US West (Oregon) for Japanese and English (AU) skills.
