When it comes to network security, we use firewalls for perimeter defense. It helps to define security boundaries for infrastructure. There are many conversations about validity of perimeter defense against modern security threats as its more about identities now. However, firewall is still the most commonly used tool to control in & out communications in a network.
In Azure so far, we…
In Hyper-V or VMware virtualization environment, Enable/Disable NIC in a VM is not a big deal. Even if you do not have NIC or valid IP configure, administrators still can connect to VM as it does have “Console” access. Few weeks ago, I received an email from one of my regular blog readers. He accidently disabled NIC in azure vm and he lost RDP access to it. since there is no console…
In my previous post I have explained what is Azure Accelerated networking and how it works. If you didn’t read it yet, you can do it using http://www.rebeladmin.com/2018/01/azure-accelerated-networking/ . In this post I am going to show how we can create VM with AN and verify its actions.
There are few limitations we need to aware before we use Azure Accelerated networking.
1.
Early January Microsoft announced general availability of Azure Accelerated Networking (AN). It is now available for all the regions. This will improve the VM’s performance as its offloading software-define networking from CPU to FPGA-based SmartNICs. To make it more interesting, it can provide up to 30Gbps networking throughput without any additional charge.
How it works?
If you…
