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 The documentation is months out of date and the last guy to configure anything on that box has since left the company to ply his trade somewhere that will more fully appreciate his Ops cowboy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.
Puppet Labs just released the 2014 State of DevOps Report. The research team interviewed companies from multiple industries and various sizes, from startups to global firms with over 10,000 employees and had over 9,200 respondents in all. The report shows us that not only is DevOps working within the enterprise, but it is also driving higher employee satisfaction.
Most Enterprise CMDB offerings are a joke. They've always been a joke. Just another white elephant system sucking time and money out of IT Budgets. What most, if not all, become are simply inventory systems. They're not even good for that half the time.
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.
IT testing automation is an important concern of businesses, and a growing field in which IT professionals are able to make a name for themselves. If you are not already involved in automated IT testing, here are a few of the most important skills to have when holding an automation related position.
It's been really interesting to watch the dramatic uptick in activity around the automation space the last year or two. I don't need to go into too much detail on the benefits that automation offers here; consistency and scalability are two of the more prominent that come to mind. What has struck me, though, is that it feels like the way that companies are going about it is missing a key step.
The Sinkhole That is Manual Configuration Testing Testing is a crucial part of software development: it involves the execution of a program with the goal of locating errors. Successful tests are able to uncover new errors that can then be corrected before the software is released.
Testing environment configurations in enterprise environments manually with scripts is difficult, just because there are so many factors involved. These can include applications, hardware, and device compatibility issues that can arise at any point within the implementation, areas which may be difficult to determine in the pre-implementation stage. Worse yet, the larger the network infrastructure, the more time consuming and complicated the test and the implementation processes are. This is when Environment Drift and Stateless Systems can come into play.
Before delivery to the intended party, a system should be tested to figure out whether the requirements set forth in the contract have been met. Configuration acceptance testing is the fundamental means to assuage all doubts that the system will fall short of its intended purposes. It is an essential part of the testing phase of the Software Development Life-Cycle (SDLC), and perhaps the most vital in its category. The way in which the components of the system interact is the sure fire means of determining the susceptibility of the system to frequent errors and ultimately the strength of resistance to its implementation. Configuration acceptance testing is pivotal to the SDLC, and as such will be an integral part of the Application Life-cycle Management (ALM) policy of any firm. It reveals any available bugs and inadequacies in the system, enhancing the process of error correction and formulation of a suitable plan of action in the event undiscovered errors manifest and affect the system after it has been implemented.
This is a pretty common response we get from people we're explaining our product to. There is logic to it but we don't believe it's necessarily reasonable. To illustrate our viewpoint on this we thought we'd paraphrase a conversation we had with a prospective client recently.
You've used Chef/Puppet to automate your infrastructure, you can provision your virtual environment from scratch and deploy all your applications in minute. It’s magical. You've achieved Configuration Management Nirvana. What you've built is repeatable, saves time, increases efficiency and removes human error.
