By default Azure does not provide any network traffic isolation between the subnets in VNETs. This creates a unique challenge for IT network and security professionals who have multiple subnets in Azure and would like to provide segmentation within the VNETS; an architecture that is common in on premise networks, for both physical and virtual infrastructures, for mitigating various security concerns. Azure NSGs (Network Security Groups) provides solutions for such virtual network segmentations without using any additional virtual appliances.
