SD WAN Segmentation and POC Tools

SD WAN microsegmentation allows admins to segment traffic according to application characteristics and network policies. The default settings are designed for the best possible performance and are also compatible with all major operating systems, also there are services that specialize in the use of SD WAN technologies and that you can find at sites such as https://www.fortinet.com/solutions/small-business/security-sd-wan.

POC

The POC tool is the new feature in vSphere 6.5. It is a great tool for debugging and analyzing issues that occur due to the virtualization environment, and is also great for learning new things about how vSphere works, such as virtual storage, VMDK/VHDX/VMX/DAS or Fault Tolerance. POC is now built in with the vSphere Web Client. With POC you can view and create a virtual machine as a new host and also modify the configuration of the host while it is running. Once your new virtual machine is running and you are ready to deploy, POC provides you a way to deploy an OS, the network configuration, the virtual machine’s vmx file, the vmkernel and other features that a host has. It also provides you a method for inspecting and testing the OS, network, virtual machine and vmx files, in particular the virtual machines’ vmx file.

Let’s see how we can use POC in our VMWare environment.

Deploying a new VM with POC

We are going to deploy our new virtual machine from the command line using poc -vm name of the VM. POC will create the following files in the directory where the VM is being deployed.

/deploy/

The default name of the folder in which the POC is installed. /vm/vmnameofvminpoc The name of the new virtual machine. /vm/vmshell The output of the POC will be available in this folder. /vm/vmshellfile The file where the output of the POC is written. /vm/vmshellpath The path where the POC’s output is written. /vm/vmshellsubdir The subfolder containing the POC output files.

Warning: Do not use a folder as the root of the POC folder. /vm/machines/a-z0-9+/a-zw+ The name of the machine, and optionally: a-z0-9 The letter and number of the first character in the name. You can use this as a prefix to any new virtual machines that will be created within this project. /vm/virtualbox The virtual machine. Can be a path on the network, the name of a disk image, or an existing virtual machine. Note: This option is only valid when using the -vm option. /vmfs/hyper-v/vmfs-path path to the file The name of the file to be mounted under the VMFS root. When mounted with the -o option, the specified file is interpreted relative to the virtual machine directory. For example, if mount -o “mountpoint=/usr/share/my-directory” path /vmfs/hyper-v/vmfs-path/test.vmdk, then the file test.vmdk will be mounted in the virtual machine’s directory. This option only has an effect if the -vm option is also used. /vmfs/hyper-v/volumes-path path to the file The name of the file to be mounted under the VM Virtual Box.
