The Future of Cloud Networking is VMware NSX

The Future of Cloud Networking is VMware NSX

This presentation was first given at Varrow Madness 2014 and discusses why cloud networking (networking in cloud computing environments) demands a new solution like VMware NSX.

  3. Networking in the era of cloud computing Why the term

    “cloud networking” isn’t just marketing-speak
  4. 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 6 Taken from http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf
  5. CONFIDENTIAL 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) 7
  6. Components of a cloud networking platform Looking at what is

    needed to build a platform to address the needs of cloud networking
  7. CONFIDENTIAL 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 11
  8. CONFIDENTIAL Peeling back the covers a bit 15 • 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
