Networking in the era of
cloud computing
Why the term “cloud networking” isn’t just
marketing-speak
CONFIDENTIAL
NIST definition of cloud computing
• Five “essential
characteristics” of cloud
computing:
• On-demand self-service
• Resource pooling
• Rapid elasticity
• Measured service
• Broad network access

How does this affect networking?
To support cloud computing, networking must:
1. Be fully automated & programmable for integration into CMPs
(on-demand self-service)
2. Be abstracted from hardware in order to pool available capacity
(resource pooling)
3. Support programmability and integration with orchestration/
provisioning solutions (rapid elasticity)
4. Provide fine-grained visibility & accounting (measured service)
5. Support any network topology & any network equipment (broad
network access)

• Virtual switch at the edge of the network
• Centralized control over/knowledge of the logical network
topology
• Decoupled control plane and data plane
• Network isolation mechanism
• Virtualized network services (L2, L3, load balancer, firewall)
• Programmatic access for integration with CMP

• Key components of VMware NSX:
• Scale-out, highly-available controller cluster
• Northbound RESTful API for CMP integration (vCAC,
OpenStack, CloudStack)
• Virtual switch in the hypervisors at the edge (Open vSwitch
for KVM and Xen; NSX vSwitch for vSphere)
• Tunneling protocol for data plane traffic (STT, GRE, VXLAN)
• Virtualized and distributed network services (load balancing,
firewalling, VPN)
• Physical switch integration
