S3 support SNS notifications for new objects. These SNS notifications can fan out to SQS queues.

• http://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html

Logstash can read from inputs including:

• S3 input
• SQS input

but neither of these are sufficient:

• S3 input has very low performance in attempting to read for a bucket with a high number of writes. The S3 reader lands up spending most of its time listing the bucket contents vs. reading objects.
• SQS input works well. It works well with a single logstash process or a cluster of multiple processes. However, the SQS input doesn't understand the format of an SNS notification object for S3 changes.

Core Goals:

• Can test in up-to-date versions of all major browsers
• Can test on up-to-date versions of all major OSes
• Can test in IE9 (because Bootstrap v4 will support IE9+)
• Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
• Workflow for management of reference/baseline/norm screenshots
