Cloud Networking – From Theory to Practice

Why Does It Matter?

Cloud computing is the future

Regardless of personal opinions and foggy definitions

Cloud computing requires large-scale elastic data centers

Hard to build them using the old tricks

Modern applications generate lots of east-west (inter-server) traffic

Existing DC designs are focused on north-south (server-to-user) traffic

IaaS clouds require flexible VM placement and VM mobility

Hard to implement with existing VLAN-based approaches
