Now when we know what is Microsoft Azure as discussed in Understanding Microsoft Azurelet's move ahead and try understand few networking concepts in Microsoft Azure.
Virtual Networks can be used to configure and to control connectivity between virtual machines and Paas Cloud Services roles.
Virtual Networks (VNets) helps in extending on premises network into cloud.
VNets enable a direct communication between a VM and a Pass Cloud Service.
VM's in aVNet can communicate directly with any other VM in the VNet,even if it is in a different Iaas cloud service.
Can i use the similar private IPv4 range as used in my on premises network ?
Yes we can use the same IPv4 range as used in on-premises network in Azure VNets.
2) 172.16.x.x -172.31.x.x
How can i move my on premises server to Cloud?
Moving an on -premises server to cloud can be done by using VPN, which can help connect our on premises network to Azure VNets and to the VM's and Pass cloud services which it contains.
Customization of my on premises DNS servers in possible?
Customization of on premises DNS servers is supported to ensure that your on premises computers can resolve the IP address of virtual servers in VNets.
What are the available options to connect on premises network to Azure VNet.
- Point-to-site VPN - Connects a single computer to VNet, to create such a connection type we need to configure each on premises computer.
- Site-to-site VPN- It connects with on premises network and all the computers to VNet, configuration of gateway and Routing in on premises network is required.
- Express Route- Dedicated service which helps us to connect on premises network to Azure VNet over a dedicated private connection provided by connectivity provider.
