Setting path parameter when uploading cloudfront ssl certificate

Tags:

When you want to use your own SSL certificate on Cloudfront, you must upload your certificate to IAM. In order for the certificate to be usable at cloudfront, its path must be prefixed with /cloudfront/, else it will not show up in the list.

The information below is distilled from a forum post at the AWS forum. The explanation is for when you are use the aws cli to upload the certificate (which is the only possible way at the moment of writing this post).

aws iam upload-server-certificate --server-certificate-name my_cert --certificate-body file://my_cert.crt --private-key file://my_key.pem --certificate-chain file://intermediate_and_root.crt --path /cloudfront/

It is possible to differentiate further in the path, it can be --path /cloudfront/whateveryouwanthere/, for exaample.

Amazon Elastic Transcoder Notifications

The Elastic Transcoder can be configured via the Simple Notification Service (SNS) to send notifications when a transcoding job changes
it state (new, in progress, completed, etc.). The details of these notifications are not defined clearly in the documentation, which is
why I list them in this post. These are actual notification from my set up in AWS. See the documentation
on how to set up the notifications.

Each notification has the default attributes every notification has. The Message attribute has a JSON encoded string that contains the
Elastic Transcoder specific information. See examples below, I only use the COMPLETED and ERROR type of notifications.

From the data the URL to the video can be deduced, if you know the configured output bucket for the pipeline in the Elastic Transcoder.
