Hybrid Cloud Networking

This document discusses hybrid cloud networking challenges and solutions. It presents typical web application deployments on-premises and in the cloud. Architectural challenges with hybrid clouds include performance, reliability, and security. Implementation challenges involve using switched versus routed networks and managing IP addresses, routes, and network appliances across environments. The document proposes two approaches for hybrid cloud networking - a routed virtual private cloud using routing and firewalls, and a switched virtual private cloud using virtual switches and tunnels to simplify connectivity while maintaining security and performance.

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?
