First off, proud to announce that Cisco asked me to produce a blog post, and decided it was good enough to release into the wild on their site!!!

www.packer.io – Packer is an open source tool for creating identical machine images for multiple platforms from a single source configuration. Packer is lightweight, runs on every major operating system, and is highly performant, creating machine images for multiple platforms in parallel. Packer does not replace configuration management like Chef or Puppet. In fact, when building images, Packer is able to use tools like Chef or Puppet to install software onto the image.

Veeam – Learn Powershell – From Basics To A Coding Star. With the release of Windows Server 2012, Microsoft’s PowerShell has moved toward automation. Our courses are designed to help you become familiar with the powerful PS scripts.

VMware

PowerCLI – Gathering VMHost NIC Driver info – There’s nothing worse than having inconsistencies in a VMware cluster. This includes patch level, driver level and definitely firmware levels. In this particular case, the focus is on the physical network adapters

Memory tuning of VMware vCenter Server Appliance (VCSA) – When you deploy a VMware vCenter Server Appliance it comes configured with a standard of 8 GB Memory. For a lot of smaller environments this is too much and you can re-configure the JVM heap size for the vCenter Server processes and therefore consume less memory.

PowerCLI – Setting up vSwitches and Port Groups – Always handy to have, personally I think you can automate pretty much all of the VMware install of a new environment.
