7. 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?
