Subnets and subnet groups - Amazon MemoryDB (original) (raw)
A subnet group is a collection of subnets (typically private) that you can designate for your clusters running in an Amazon Virtual Private Cloud (VPC) environment.
When you create a cluster in an Amazon VPC, you can specify a subnet group or use the default one provided. MemoryDB uses that subnet group to choose a subnet and IP addresses within that subnet to associate with your nodes.
This section covers how to create and leverage subnets and subnet groups to manage access to your MemoryDB resources.
