## Amazon Alexa Developer Account

Create or have access to [Amazon Developer Services](https://developer.amazon.com/) account - sign-up is free - if you do not have account then create one

> **_NOTE:_** This account owns your Alexa skill for Smart Mirror. Make sure the account you are using is the same account you use in your Alexa device (Phone / Echo) and connect this with AWS CodeStar

## AWS Account

If you do not have existing AWS account please see instructions how to create one.

Please see [Create and activate AWS Account](https://aws.amazon.com/premiumsupport/knowledge-center/create-and-activate-aws-account/)

> **_NOTE:_** We use AWS region Ireland (eu-west-1) throughout examples - other regions should work as well.

## AWS costs from this project

This solution will incur cost based on your usage.
- Used services are [AWS Free Tier eligible](https://aws.amazon.com/free/)

Free tier covers:
* EC2 for Cloud9 (running only when IDE is used - by default it shuts down after 30 minutes)
* Persistent storage (S3 Artifacts + EBS for Cloud9)
* Data Transfer out is free up to 100GB
* One active AWS CodePipeline

Additional costs:
There is cost per on-premise AWS CodeDeploy deployment as per https://aws.amazon.com/codedeploy/pricing/ 

Estimation of cost outside of Free Tier is less than 1$ per month - depending on number of deployments you make.
