In the builder you can publish and update your Mame Website directly to an Amazon AWS S3 Bucket. Amazon S3, or Simple Storage Service is a static file hosting service provided by Amazon Web Services (AWS). You can use it to host your Mame website, as it's only made of HTML, CSS and JavaScript and you don't need any server side programming languages. You only pay for the storage and traffic you really use. Coupled with Amazon Cloudfront it even offers high-performance hosting world-wide.
Create Security Credentials for Mame
In order to upload the website's files we need an Access Key for API access. Login into your AWS account (or create a new one if you don't have one yet) and choose 'My Security Credentials' in the User menu.
Next create a new access key and store the credentials. Mame needs both, the Access key id and the Secret.
