Study Notes

Virtual Network in Microsoft Azure

A Virtual Network (V-NET) acts as an organization's network in Microsoft Azure.

Characteristics of V-NETs in Microsoft Azure

A V-NET is a virtual private network in Microsoft Azure.
By default, V-NETs in Microsoft Azure are isolated from each other.
A V-NET in Microsoft Azure must be configured with a valid IP address range.

Routing and Connectivity in Microsoft Azure

VMs in different subnets within a V-NET can route to each other directly.
Dynamic assignment of IP addresses in Microsoft Azure means that IP addresses are assigned automatically.
Static assignment of IP addresses in Microsoft Azure means that IP addresses are assigned manually.
The public IP-address of a VM in Microsoft Azure exists as a resource that can be assigned to a VM.

Connectivity Options between V-NETs in Microsoft Azure

The two main ways to achieve connectivity between different V-NETs in Microsoft Azure are peering and gateways.

Graphical Overview of a Network in Microsoft Azure

The graphical overview of a network in Microsoft Azure includes resources such as VMs, subnets, and V-NETs.

Layer 2 Traffic in Azure

Azure does not allow broadcast, multicast, and non-IP traffic in Layer 2 modes.

Role of the SDN Virtual Router in Azure

The SDN virtual router in Azure plays the role of a router, facilitating network connectivity.

Traffic Allowed in Cloud Computing in Azure

The type of traffic allowed in cloud computing in Azure is IP traffic.

Purpose of Azure V-NET Peering

The purpose of Azure V-NET peering is to enable connectivity between different V-NETs.

Third-Party Resources for Connectivity in Azure

Third-party resources, such as ExpressRoute and VPN gateways, can be used for connectivity in Azure.

Role of the Underlay Network in Azure

The underlay network in Azure provides the underlying infrastructure for network connectivity.

Communication between VMs and the Internet in Azure

When a VM wants to communicate with another VM or access the internet in Azure, it sends traffic through the SDN virtual router.

Limitations in Azure for Layer 2 Modes

Azure does not allow Layer 2 modes that use VLAN tags, MAC addresses, or non-IP protocols.

Configuration Requirements for a VM in Azure

A VM in Azure must be configured with a valid IP address and subnet mask to receive traffic.

Purpose of the Router Icon in Azure

The router icon at the center of the image in Azure represents the SDN virtual router, which enables network connectivity.
