Technology Short Take #72

Welcome to Technology Short Take #72. Normally, I try to publish these on Fridays, but some personal travel prevented that this time around so I’m publishing on a Monday instead. Enough of that, though…bring on the content! As usual, here’s my random collection of links, articles, and thoughts about various data center technologies.

A Triple-Provider Vagrant Environment

In this post, I’d like to share with you some techniques I used to build a triple-provider Vagrant environment—that is, a Vagrant environment that will work unmodified with multiple backend providers. In this case, it will work (mostly) unmodified with AWS, VirtualBox, and the VMware provider (tested with Fusion, but should work with Workstation as well). I know this may not seem like a big deal, but it marks something of a milestone for me.

Why I'm Now Using VirtualBox with Vagrant

One of the things I often tell people is, “Use the right tool for the job.” As technologists, we shouldn’t get so locked onto any one technology or product that we can’t see when other technologies or products might solve a particular problem more effectively. It’s for this reason that I recently made VirtualBox—not VMware Fusion—my primary virtualization provider for Vagrant environments.

Installing a Specific Version of Docker Engine

In this post, I’m going to show you how to install a specific version of the Docker Engine package on Ubuntu. While working on a side project (one that will hopefully bear fruit soon), I found myself in need of installing a slightly older version of Docker Engine (1.11 instead of 1.12, to be specific). While this task isn’t hard, it also wasn’t clearly spelled out anywhere, and this post aims to help address that shortcoming.

Spousetivities in Barcelona

If you’re going to be in Barcelona for either VMworld EMEA (running the week of October 17) or the fall 2016 OpenStack Summit (running the week of October 24), then I recommend you plan for your spouse/partner/girlfriend/boyfriend/whatever to join you for what I believe are some pretty spectacular Spousetivities.

Using Vagrant with AWS

In this post, I’d like to describe how to use Vagrant with AWS, as well as provide a brief description of why this combination of technologies may make sense for some use cases. In some respects, this post is similar to my posts on using Docker Machine with OpenStack and using Vagrant with OpenStack in that combining Vagrant with AWS creates another clean “provider/consumer” model that makes it easy for users to consume infrastructure.

A Follow Up on SSH Bastion Hosts

This post is a follow-up on my earlier post on using an SSH bastion host. Since that article was published, I’ve gotten some additional information that I wanted to be sure to share with my readers. It’s possible that this additional information may not affect you, but I’ll allow you to make that determination based on your use case and your specific environment.

VMworld 2016 Day 2 Keynote

This is a liveblog of the day 2 general session here at VMworld 2016 at Mandalay Bay in Las Vegas, NV. Today, VMware is expected to talk more about containers, end-user computing, and other topics not covered in yesterday’s general session (which focused heavily on Cross-Cloud Services, VMware’s new set of SaaS-based offerings for multi-cloud management).

VMworld 2016 Day 1 Keynote

This is a liveblog of the day 1 keynote at VMworld 2016 in Las Vegas, NV. I managed to snag a somewhat decent seat in the massive bloggers/press/analysts area, though it filled up really quickly. Based on the announcements made this morning, it should be a great general session, and I’m really interested to see how its received by the community.
