Traditionally, the first post in the series describes how to setup a development environment. This time I’ll do it DevOps-style. I’ll show how to use Packer to automatically create and configure a VM with UNetLab and Jenkins pre-installed.

In this post, I’d like to cover some of the new Docker network features. Docker 1.9 saw the release of user defined networks and the most recent version 1.10 added some additional features.

I’d like to share some personal news with you, industry watchers and fans of VMware’s network virtualization offering.

Having spent the last decade in a deep, but narrow operating roll, I have decided that going forward I would like to engage much more broadly.
Recently, Andreessen Horowitz VC reached out about a GP position in the enterprise space. Given my familiarity and history with the firm, and how rare these opportunities are, I knew this was my chance. So I accepted. Continue reading
