Do I need buy two license for a Master-Standby cluster?
I use Veritas Cluster Server to build a mater-standby cluster, do I need buy two license for my cluster?
If two instances of Wowza are running at the same time they each need to be licensed. If the standby server is stopped until it is needed, and the primary is stopped when the standby is started and in use, then they could use the same perpetual license and it will only count as one instance in a monthly subscription license. There is a some tolerance in the subscription license for overlap, an hour I think.
