Amazon wants developers to be fully locked into its ecosystem, which is why on Wednesday it announced a new program to give additional promotional credits to developers that build Alexa skills and use Amazon Web Services (AWS).
Alexa developers are already provided with AWS Free Tier, which gives one million AWS Lambda requests and 750 hours of Elastic Compute Cloud time per month, but if developers exceed the limit they are charged.
