Considerations for customizing the solution

Bucket Region

If you specify your own S3 ingestion (and/or proxy) buckets, ensure the bucket(s) are in the same AWS Region as the Region where the solution is deployed to avoid cross-Region data transfer costs.

Bucket CORS settings

If you decide to use your own Amazon S3 ingest (and/or proxy) bucket, the solution updates your bucket's CORS settings to allow the web interface to perform cross origin GET/POST requests. The following example shows the CORS settings:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>https://<cf-id>.cloudfront.net</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>PUT</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>HEAD</AllowedMethod>
    <AllowedMethod>DELETE</AllowedMethod>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <ExposeHeader>Content-Length</ExposeHeader>
    <ExposeHeader>ETag</ExposeHeader>
    <ExposeHeader>x-amz-meta-uuid</ExposeHeader>
    <ExposeHeader>x-amz-meta-md5</ExposeHeader>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>
