BrokerAZDistribution (string) --
The distribution of broker nodes across Availability Zones. This is an optional parameter. If you don't specify it, Amazon MSK gives it the value DEFAULT. You can also explicitly set this parameter to the value DEFAULT. No other values are currently allowed.
Amazon MSK distributes the broker nodes evenly across the Availability Zones that correspond to the subnets you provide when you create the cluster.
ClientSubnets (list) -- [REQUIRED]
The list of subnets to connect to in the client virtual private cloud (VPC). AWS creates elastic network interfaces inside these subnets. Client applications use elastic network interfaces to produce and consume data. Client subnets can't be in Availability Zone us-east-1e.
