 <p>They are very similar but have some nuances to them. For example, AWS does not allow all traffic within the VNET by default, whereas Azure NSGs allow all traffic between VMs in the VNET. Unfortunately, I don't have a guide for translating from one to the other. The best reference for Azure NSGs: <a href="https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-nsg/" rel="nofollow">https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-nsg/</a>. This documents those default inbound and outbound rules, too. </p>
