What is Virtual Network?
- The process of combining hardware and software network resources and network functionality into a single, software-based administrative entity is called a virtual network (VNet)
- VNet is the interconnection between devices (i.e. VMs, virtual servers and others) in a virtualized computing environment
- A VNet is a network where connection between devices are done through software and wireless technology
- The Internet as a whole may be characterized as a virtual network!
- Virtual networking technology makes it possible to control one or more remotely located computers or servers over the internet
Virtual Network in Azure
- Network security groups: containes security rules to filter network traffic
- Address space:
- an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device
- the amount of memory allocated for all possible addresses for a computational entity, such as a networked computer
- an address space must be specified when creating VNet
- to segment the virtual network into one or more sub-networks
- when creating VNet, a default subnet will be created by default
- VNet is scoped to a single region/location
- multiple VNets from different regions can be connected together using Virtual Network Peering
