Identifying subnet and Availability Zone requirements
Subnets and Availability Zones apply as follows:
-
Inputs – Some MediaLive input types are in your VPC, which means that they are in a specific subnet. For example, an RTMP input can be in your VPC. For more information, see Input types, protocols, and upstream systems .
-
Endpoints – The channel endpoints are in a subnet.
-
Destinations –The IP addresses for outputs in the VPC are in a subnet.
You must identify the VPCs and subnets for the MediaLive endpoints and for those of your output destinations that are an address in your VPC. You must consider the following:
-
You must make sure that the setup follows the rules for allocation across subnets and across Availability Zones. See Use case A – no VPC inputs and the section that follows it.
-
Each subnet must have a private CIDR block (a range of IP addresses).
-
Each subnet must have at least two unused addresses in that block.
