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 most common scenarios hackers targets open ports in servers to gain access. It can be web server port, RDP ports, SQL ports etc. If genuine users also use same ports to access the system it’s hard to keep these ports closed. There are other methods such as firewalls that we can use to secure the access but it will still keep the ports open. when it comes to public clouds, its increase…
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…
