    Handoff to Day-N Automation with vSphere Content Libraries and Netbox

    The challenge with build automation is too much convenience Think about it. If it's easy to compose and deploy workloads, it's also easy to develop sprawl, and a good system designer would have methods in place to mitigate that. In a previous post I covered how to deploy vSphere VMs with Ansible and the Automation …

    Deploy vSphere VMs with Ansible!

    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 …

    Why Automate? VM Deployment with vSphere's REST API

    VMware introduced RESTful APIs with their vSphere 7.0 release train; migrating from the old MOB APIs is a welcome choice. REST clients provide a powerful tool for automating processes, but it's important to embody reliable practices when interacting with infrastructure. The neat thing about published and documented …

  • What happens to packets with a VMware vSphere Distributed Switch?

    Share on: twitter facebook linkedin copy

    Distributed Virtual Port-Groups (dvPGs) in vSphere are a powerful tool for controlling network traffic behavior. vSphere Distributed Switches (vDS) are non-transitive Layer 2 proxies and provide us the ability to modify packets in-flight in a variety of complex ways. Note: Cisco UCS implements something similar with …

  • Security patches are available for VMware vCenter 8.0 - Let's try the new vCenter Lifecycle Manager!

    Let's take a look at the new lifecycle management process for vCenter. The old process via the VAMI was easy to execute - the industry is upping the ante with automated pre- and post-testing. Cisco's NX-OS installer is another example - complex procedures (in Cisco's case, sequential PGA or microcode updates) invite …

    Not every application is designed to leverage a load balancer. Early load balancing solutions capitalized on this fact - which may seem odd. The solution to the supportability issue creates new opportunity; we'll look at some examples here. Adjusting application behaviors quickly becomes a powerful tool when enhancing …

    Rapidly deploying Linux servers to meet a whim represents the essence of home lab activities, but we spend a great deal of time spinning/configuring machines to meet our specs. Worse, we lose a great deal of time keeping them properly configured and up to date, and none have the privilege of unlimited lab time. Let's …

    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 …
