Detecting Heartbleed with UpGuard

UpGuard made detecting and fixing the Heartbleed vulnerability a lot less painful than it could have been. With a combination of Search and Policies we quickly and easily gained confidence that our servers were patched.

Controlling DNS Configuration Drift

We received a lot of positive feedback regarding our last article on Controlling SQL Configuration Drift so thought it might be a good idea to continue along that same theme of analysis and follow it up with an article about DNS configuration and some simple steps you can take to prevent configuration drift.

Monitoring Database Nodes to Remediate Configuration Drift

Controlling database configuration drift is a tricky subject. It's a topic that comes up frequently for us here at UpGuard and customers are always keen to know how they can go about taking control and simplify their configuration management processes. We've all experienced at some time or another that issue that was the result of a database migration that didn't complete, a column that has mysteriously changed data type or an old version of a stored proc or view being restored to a new database.

PowerShell Desired State Configuration (DSC) with UpGuard

Going from nothing to automation using one of the many tools available can be a daunting task. How can you automate systems when you’re not even 100% sure how they’ve been configured? The documentation is months out of date and the last guy to configure anything on that box has since left the company to ply his trade somewhere that will more fully appreciate his Ops cowboy routine.

Comparing Containers and Generating Dockerfiles with UpGuard

Tonight I gave a talk on comparing containers and generating Dockerfiles. Instead of providing the slides, which are pretty lame by themselves, I thought I'd write up the talk in a proper context. UpGuard has a number of use cases, one of which highlighted for the talk was migrating the configuration of environments from one location to another. Traditionally we have helped some of our customers scan their configuration state and generate executable tests based on those configuration items as well as allow scanned configuration from multiple machines to be compared.

If the Phoenix Project had UpGuard

At UpGuard we've got many decades of experience in large enterprises and are very familiar with the sorts of problems that arise in those sorts of environments. Even for those who have lived through it though, it can be hard to explain to people who haven't. That's why we require all our new employees to read The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win by Gene Kim, Kevin Behr and George Spafford. It does a great - and surprisingly entertaining - job of describing these issues. It also explains how the lessons learnt from years of Lean Manufacturing apply directly to IT. We know that no tool is a silver bullet, but if the employees at Parts Unlimited had UpGuard then it may have been an entirely different story. I've chosen some key excerpts from the book so that we could see how things may have been different.

Getting Started with Puppet - Hello World!

As there's a lot of interest out there in the various IT automation tools on offer I thought I'd do a series of blogs covering getting started on each. In particular I wanted to put them to the test regarding how simple it is to go from zero to "Hello World" *. This way I get to play the truly dumb user (not much of a stretch, I know), which is kinda fun too.
