Introduction to Virtualized Networking

Home » Webinars » Network Virtualization » Introduction to Virtualized Networking

Introductory webinar describing the networking requirements of server virtualization and IaaS cloud services, workload mobility, large-scale virtual networking solutions and multi-tenant isolation. This webinar is the recommended entry-level starting point for networking engineers interested in virtualization and cloud services.

19:18 Introduction

Let's start with the basics: what is server virtualization, what are hypervisors, and what how is Infrastructure-as-a-Service implemented.

59:25 Virtual Networks

Virtual machines running within a hypervisor have to communicate with their clients through an outside network, and be able to access storage.

This section describes common mechanisms used to implement virtual networking and virtualized storage, including virtual disks, virtual switches, and multi-tenant isolation or security zones.

14:59 Virtual Network Services

You shouldn't use traditional hardware-based network appliances if you want to give the application developers the ability to deploy application stacks on demand. Modern cloud infrastructures therefore offer firewalling-as-a-service and loadbalancing-as-a-service.

These services are commonly implemented with virtual appliances and distributed in-kernel firewalls. Both technologies are described in this section.

17:36 Scaling the Virtual Networks

VLANs were commonly used to implement virtual networks, resulting in brittle environment using end-to-end bridging across whole data centers. Modern designs use MAC-over-IP encapsulations (overlay virtual networking). This section describes the basics of overlay virtual networking, you'll find more details in other network virtualization webinars.
