Six DevOps myths and the realities behind them

Angela McCallister - August 28, 2016
At OpenStack Days Silicon Valley 2016, Puppet Founder and CEO Luke Kanies dispelled the six most common misconceptions he’s encountered that prevent organizations from adopting and benefiting from DevOps.
Over a five-year period, Puppet conducted market research of 25,000 people that shows the adoption of DevOps is critical to building a great software company. Unfortunately, however, many companies find that the costs of the cultural change are too high. The result is that these firms often fail to become great software companies -- sometimes because even though they try to adopt the DevOps lifestyle, they do it in a such way that the change in a way doesn't have enough real value because the changes don’t go deep enough.
You see, all companies are becoming software companies, Kanies explained, and surveys have shown that success requires optimization of end-to-end software production. Organizations that move past barriers to change and go from the old processes to the new way of using DevOps tools and practices will be able to make the people on their team happy, spend more time on creating value rather than on rework, and deliver software faster.
Key points in the 2016 State of DevOps Report survey show that high-performing teams deploy 200 times more frequently than average teams, with over 2,500 times shorter lead times, so the time between idea and production is minimal. Additionally, these teams see failure rates that are 3 times lower than their non-DevOps counterparts, and they recover 24 times faster. The five-year span of the survey has also shown that the distance between top performers and average performers is growing.
In other words, the cost of not adopting DevOps processes is also growing.
Despite these benefits, however, for every reason to adopt DevOps, there are plenty of myths and cultural obstacles that hold organizations back.

Myth #1: There's no direct value to DevOps

The first myth Kanies discussed is that there’s no direct customer or business value for adopting DevOps practices. After all, how much good does it do customers to have teams deploying 200 times more frequently?
Quite a lot, as it happens. DevOps allows faster delivery of more reliable products and optimizes processes, which results in developing software faster. That means responding to customer problems more quickly, as well as drastically slashing time to market for new ideas and products. This increased velocity means more value for your business.

Myth #2: There's no ROI for DevOps in the legacy world

The second myth, that there’s no return on investment in applying DevOps to legacy applications, is based on the idea that DevOps is only useful for new technology. The problem with this view, Kanies says, is that the majority of the world still runs in legacy environments, effectively ruling out most of the existing IT ecosystem.
There are really good reasons not to ignore this reality when planning your DevOps initiatives. The process of DevOps doesn’t have to be all-or-nothing; you can make small changes to your process and make a significant difference, removing manual steps, and slow, painful, and error-prone processes.
What's more, in many cases, you can’t predict where returns will be seen, so there’s value in working across the entire organization. Kanies points out that it makes no sense to only utilize DevOps for the new, shiny stuff that no one is really using yet and neglect the production applications that users care about -- thus leaving them operating slowly and poorly.

Myth #3: Only unicorns can wield DevOps

Myth number three is that DevOps only works with “unicorn” companies and not traditional enterprise. Traditional companies want assurances that DevOps solutions and benefits work for their very traditional needs, and not just for new, from-scratch companies.
Kanies points out that DevOps is the new normal, and no matter where organizations are in the maturity cycle, they need to be able to figure out how to optimize the entire end-to-end software production, in order to gain the benefits of DevOps: reduced time to market, lower mean time to recovery, and higher levels of employee engagement.

Myth #4: You don't have enough time or people

The fourth myth is that improvement via DevOps requires spare time and people the organization doesn’t have. Two concepts at the root of this myth are the realities that no matter what you do, software must be delivered faster and more often and that costs must be maintained or decreased, and organizations don’t see how to do this -- especially if they take time to retool to a new methodology.
But DevOps is about time reclamation. First, it automates many tasks that computers can accomplish faster and more reliably and an overworked IT engineer. That much is obvious.  
But there's a second, less obvious way that DevOps enables you to reclaim time and money. Studies have shown that on average, SREs, sysadmins, and so on get interrupted every fifteen minutes -- and that it takes about thirty minutes to fully recover from an interruption. This means many people have no time to spend hours on a single, hard problem because they constantly get interrupted. Recognizing this problem and removing the interruptions can free up time for more value-added activity and free up needed capacity in the organization.

Myth #5: DevOps doesn't fit with regulations and compliance

Myth number five comes from companies subject to regulation and compliance who believe this precludes adoption of DevOps. However, with better software, faster recovery, faster deployments, and lower error rates, you can automate compliance as well. Organizations can integrate all of the elements of software development with auditing, security, and compliance to deliver higher value, and in fact, if these aren’t all done at once, companies are more than likely to experience a failure of some sort.

Myth #6: You don't really need it

Kanies says he hasn’t heard the sixth myth often, but once in a while, a company concludes it doesn’t have any problems that adopting DevOps would fix. But DevOps is really about being good at getting better, moving faster, and eliminating the more frustrating parts of the work, he explains.
The benefits of adopting DevOps are clear from Kanies’ points and from the data presented by the survey. As he says, the choice is really about whether to invest in change or to let your competitors do it first. Because the top performers are pulling ahead faster and faster, Kanies says, and “organizations don’t have a lot of time to make a choice.”
