Hybrid Cloud Networking• Architectural Challenges
– Performance• Latency v. Consistency
– Reliability• Failover, DR/HA strategies
– Security• Switched (E’net frames) v. Routing (IP Packets)• Firewalls, Encryption, Access Controls, etc.
• Implementation Challenges– Switched v. Routed
• Bridging (simple) v. Routing (not so simple)• Application Requirements (broadcast/multicast, discovery, failover, etc.)
– IP addresses• Dynamic v. Static• Routable v. Non-routable
– Routes to and from systems• Network Appliances and Leaky Abstractions
• Complexity and Agility– How does all this impact primary objectives of cloud efforts?
