Message VPNs
Message VPNs allow for many separate applications to share a single Solace PubSub+ software or appliance event broker while still remaining independent and separated. Basically, Message VPNs enable the virtualization of an event broker into many individual virtual event brokers.
Message VPNs allow for the segregation of topic space and messaging space by creating fully separate messaging domains. Message VPNs also group clients connecting to a network of Solace PubSub+ event brokers so that messages published within a particular group are only visible to clients that belong to that group. Each client connection is associated with a single Message VPN.
