Almost any organization that I’ve had the pleasure of talking with, uses Git either for code repositories where their developers work or for doing version control on their infrastructure systems. Git is an excellent version control tool and is widely used for both developers and also infrastructure configuration. This post goes into how to put the VMware NSX configuration into version control using Git.
Not all infrastructure components (server systems, network devices, etc) have a proper audit log on what happens in the configuration and who is doing what exactly. This is where version control can lend a helping hand … Read more
Over the last couple of months, Sander, Anne Jan and I have been working on a security whitepaper that lays out a practical implementation of zero trust while interfacing with a helpdesk system. In this case, OTRS.
It’s all about how engineers can get access to servers to perform maintenance, once your environment is properly micro-segmented. This whitepaper talks about the challenges you have when you’re micro-segmented and how you can resolve these challenges. Using OTRS as an example, this document lays out how to configure a help desk system like OTRS to interface with NSX to gain network … Read more
PowerShell is about making things easy and consumable. Same goes for PowervRNI, making repetitive tasks in vRealize Network Insight easier and make it possible to extract information from vRNI.
It’s not that easy to load a custom module into PowerShell though, you have to download 1 or 2 files, then load it into your PowerShell session by referencing those local files. The PowerShell Gallery is a pretty awesome way to also make module management very easy. All you have to do is use the Install-Module command and it downloads and installs the module for you.
For the module authors, … Read more
This is the second post in a series on how to use PowervRNI to manage Applications within your vRealize Network Insight environment. If you’d like to learn about managing Data Sources with PowervRNI, check here.
Introduced in vRealize Network Insight 3.2 in the begin of 2017, Applications are logical containers which can contain the structure of applications (including tiering). You can use these application containers to better visualize what network flows are going between specific applications or even application tiers. Next to insights into your applications, you can also use it to take a per-application approach to micro-segmentation, … Read more
This is the first post in a series on how to use PowervRNI to manage your vRealize Network Insight environment. Starting with Data Sources.
Brief background; data sources in vRNI are endpoints from which vRNI retrieves information from. Examples are: vCenter, NSX, Switches, Routers, Firewalls, an AWS account or converged infrastructure systems like Cisco UCS or HP OneView.
Adding data sources is usually only performed when vRNI is installed into the environment and every time a new endpoint is added to your environment (for example a new vCenter environment, or when a new switch is plugged in).… Read more
I am excited to introduce PowervRNI to the world! In the 3.6 release of vRealize Network Insight (vRNI) in November, there was a public API added. Through this API, you can offload certain tedious tasks like creating applications and managing data sources. I was using the private API for a couple of things already, like importing data sources. With the release of the public API, I could move those things to use the public (and supported) API. Ever since then, I’ve been working on PowervRNI.
The first release of PowervRNI is on GitHub here. With this … Read more
As a wise man said; now for something completely different. This post is going to be just that.
I received a Amazon Kindle on christmas and absolutely love it. It has replaced hauling around a bunch of physical books and made my life a lot easier when it comes to managing highlights and notes about the topics in the books (I read a lot of educational text).
Previously I had a physical notebook with me that I translated into electronic notes by hand. I use Evernote for all my note taking purposes. With the Kindle, all your highlights and notes … Read more
