(Read more about Hosting Your Own Custom Skill Web Service.) With the AWS Free Tier, you get 1,000,000 free requests per month, up to 3.2 million seconds of compute time per month. Learn more at https://aws.amazon.com/free/. In addition, Amazon now offers AWS Promotional Credits for developers who have live Alexa skills that incur costs on AWS related to those skills.
