Microsoft Azure Network Security Group (NSG) Example

Here is a quick example of using Network Security Group (NSG) within Microsoft Azure to protect your workload.  In terms of design perspective you would setup a Virtual Network and then attach a large address space.  This would then be carved into smaller subnets for various workload like Internet facing traffic, middle-tier applications and back-end applications.  To control the traffic flow and enable security you can apply multiple NSG’s.  The effect would be as per diagram.
