Overlay Virtual Networking

This section contains important information you should read before starting the webinar, and describes the typical IaaS networking requirements:

• Multiple tenants sharing the same infrastructure;
• Multiple virtual networks (or routing domains) per tenant;
• Elastic and scalable solution architecture.

Traditionally we used VLANs to create multiple tenant networks... and hit numerous scalability limitations, resulting in most virtualization vendors embracing overlay virtual networks.

This section describes typical overlay virtual networking functionality, various encapsulation technologies, and interfaces between overlay networks and physical world.

Mastered the fundamentals? Let’s do a deep dive into how layer-2 forwarding, gateways, and distributed layer-3 forwarding work in overlay virtual networks.

These webinars contain more information on VXLAN and EVPN, standard technologies most commonly used to implement overlay virtual networks.

These webinars contain detailed information on various products using overlay virtual networking, from virtualization solutions (NSX and ACI) to containers (Docker and Kubernetes) and public cloud implementations (AWS and Azure).
