17. Communication & connectivitychallenges • Not every application is a server application • a number of different app styles need to communicate • proper DMZ is seldom in place • Advanced communication patterns • peer-to-peer • publish/subscribe • enabled for cross-platform and -technology • IPv4 address shortage • dynamic IP address allocation • Network Address Translation (NAT) Network Address Translation Network Firewall Machine Firewall ? Sender Receiver Dynamic IP

18. Possible Service Bus usagescenarios • Syndication • Peer-To-Peer • Callbacks, notifications • Multi-casting, Pub/Sub • Light-weight orchestration • Remote control
