I know “cloud networking” sounds like...

...but this is cloud washing!

Networking in the era of cloud computingWhy 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)

What’s in a cloud networking platform?
• 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
