Plan for delivery using Amazon VPC
You might set up the MediaLive channel for the SRT output to have output endpoints in Amazon Virtual Private Cloud (Amazon VPC). Following are some guidelines for setting up the secret in Secrets Manager and for delivery the output to MediaConnect (if MediaConnect is the destination).
Considerations for Secrets Manager
SRT outputs are always encrypted, therefore AWS Secrets Manager is always involved. There are specific requirements for the VPC subnet where you will create the channel:
-
The subnet for the channel must have a Secrets Manager endpoint.
-
The subnet for the channel and the Secrets Manager endpoint must use the same security group, which means that the same security group must be associated with the subnet and with the endpoint.
Considerations for MediaConnect
You might be delivering to a MediaConnect that also uses a VPC. This means that the SRT output egress from the MediaLive channel is on your VPC and that the MediaConnect flow has a VPC interface.
-
The administrator for your VPC must ensure that there is an appropriate route between MediaLive and MediaConnect.
