Overlay Virtual Networking

Overall rating: 4.67 Instructor: 4.89 Materials: 4.73 more …

Networking and virtualization vendors have launched numerous overlay virtual networking solutions in the last 2 years as a response to the rigidity and scalability failures of traditional VLAN-based data center virtual networks.

Not surprisingly, each vendor touts its particular (and usually proprietary) solution as the best one to solve your networking infrastructure challenges, forcing you to make tough choices when designing or deploying the network infrastructure for a private or public cloud.

This vendor-agnostic session revisits the networking needs of server virtualization and IaaS cloud computing, and describes the benefits and drawbacks of overlay virtual networks as compared to traditional VLAN-based solutions(including VM-aware networking technologies like 802.1Qbg).

The second half of the session focuses on architectural and scalability aspects of individual solutions from major virtualization vendors (Cisco, VMware, Microsoft), and open-source alternatives (OpenStack).
