    Share on: twitter facebook linkedin copy

    In a previous post, we covered how to create a virtual machine from a VM template in vSphere using Python and the REST API as an example of service-agnostic methods to invoke infrastructure resources. VMware's PowerCLI is a fantastic tool, but it's not for me. Tweaking or porting functionality from PowerCLI to other …

    Reliably executing repetitive tasks with automation is easy (after the work is done) Given enough work, self-built automation can be easy to consume. Non-consumers (engineers) need to focus on reliability and repeatability, but occasionally there's an opportunity to save time and simplify lives directly. Information …

    NSX 4 is now available, and it was a surprisingly sparse release in terms of new capabilities. NSX 4.0 appears to be a "clean house" initiative, so while it's missing "whizz-bang" new data plane features it does address a variety of issues I am happy to say are now closed: Numerous documented API …

    VMware's vDS is a bit of a misnomer In a previous post, I covered the concept of transitivity in networking - but in Layer 2 (Ethernet) land, transitivity is critically important to understanding how VMware's Virtual Distributed Switch (vDS) works. The statement "VMware's Virtual Distributed Switch is not a …

    Cisco Modeling Labs (CML) has turned out to be a great tool for deploying virtual network resources, but the "only Cisco VNFs" limitation is a bit much. Let's use this opportunity to really take advantage of the capabilities that NSX-T has for virtual network labs! Overview For the purpose of lab …

    VMware's NSX Datacenter product is designed for a bit more than single enterprise virtual networking and security. When reviewing platform maximums (NSX-T 3.2 ConfigMax), the listed maximum number of Tier-1 routers is 4,000 logical routers. Achieving that number takes a degree of intentional design, however. When …

    What is the point of all this software-defined infrastructure if you don't use it? In prior examples, it's a fairly straightforward path to SDN when deploying NSX Data Center, allowing a VI admin or network engineer to deploy virtual network resources via a GUI.

    GitOps GitOps, a term coined in 2017, describes the practice of performing infrastructure operations from a Git repository. In this practice, we easily develop the ability to re-deploy any broken infrastructure (like application managers), but that doesn't really help infrastructure engineers. From the perspective of …
