DevOps is a software engineering culture and practice that aims at unifying software development (Dev) and software operation (Ops). The main characteristic of the DevOps movement is to strongly advocateand at all steps of , from , , to deployment and . DevOps aims at shorter development cycles, , and more dependable releases, in close alignment with business objectives.
History of DevOps
In 2009 Patrick Debois coined the term by naming a conference “devopsdays”
which started inand has now spread to other countries.
The term DevOps has been used in multiple contexts.
A definition proposed by Bass, Weber, and Zhu, is:
DevOps is a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality.
In recent years, more tangential DevOps initiatives have also evolved, such as OpsDev,
, DevSecOps, and BizDevOps
DevOps as a job title
While DevOps describes an approach to work rather than a distinct role (like), job advertisements are increasingly using terms like “DevOps Engineer“.
While DevOps reflects complex topics, the DevOps community uses analogies to communicate important concepts, much like “” from the open source community.

DevOps principles demand strong interdepartmental communication—team-building and otheractivities are often used—to create an environment that fosters this communication and cultural change, within an organization.
Team–building activities can include, trust activities, and employee engagement seminars.
The goals of DevOps span the entire delivery pipeline. They include:
- Improved deployment frequency;
- Faster ;
- Lower failure rate of new releases;
- Shortened lead time between fixes;
- Faster mean time to recovery (in the event of a new release crashing or otherwise disabling the current system).
Simple processes become increasingly programmable and dynamic, using a DevOps approach.
DevOps aims to maximize the predictability, efficiency, security, and maintainability of operational processes. Very often, automation supports this objective.
DevOps integration targets, , , feature development, and in order to improve reliability and security and provide faster and cycles. Many of the ideas (and people) involved in DevOps came from the and movements.
DevOps initiatives can create cultural change in companies,
by transforming the way, , and collaborate during the development and delivery processes.
Getting these groups to work cohesively is a critical challenge in enterprise DevOps adoption.
Specifically, I’ve come to believe there are three primary practice areas that are usually discussed in context of DevOps.
- Infrastructure Automation – create your systems, OS configs, and app deployments as code.
- Continuous Delivery – build, test, deploy your apps in a fast and automated manner.
- Site Reliability Engineering – operate your systems; monitoring and orchestration, sure, but also designing for operability in the first place.
The DevOps Foundation certification focuses on improving the work flow between IT Operations professionals and software developers. This certification through improved flow of work will improve a professional’s ability to design, develop, deploy and operate software and deliver faster services.
10 companies killing it at DevOps
Much has been written about whatis, but not a lot has been said about what it can do for an organization. The trending software development approach has many , including shorter development cycles, increased deployment frequency, and faster time to market. But because it relies so heavily on increased communication, collaboration, and innovation, it can also be a catalyst for cultural change within an organization.
Here are 10 trailblazing companies that exemplify the possibilities of DevOps.
Back whenwas still run on dedicated servers, it was a constant challenge to predict to meet traffic demands and pad estimates to accommodate for unforeseen traffic spikes. As a result, about 40 percent of Amazon’s server capacity was wasted—and during the Christmas shopping season, when traffic could triple, more than three-quarters could be left unused—along with the money spent to purchase it.
Once the online retailer moved to the Amazon Web Services (AWS) cloud, it allowed engineers to scale capacity up or down incrementally. Not only did this reduce spending on server capacity, but it also spurred a transition to a continuous deployment process that allows any developer to deploy their own code to whichever servers they need, whenever they want.
Within a year of Amazon’s move to AWS, engineers were deploying code every 11.7 seconds, on average. Thealso reduced both the number and duration of outages, resulting in increased revenue.
Whenevolved its business model from shipping DVDs to streaming video over the web, it waded into uncharted waters. There weren’t any commercial tools available help keep the company’s massive cloud infrastructure running smoothly, so it turned to open source solutions. Enlisting the volunteer help of hundreds of developers, it created the , a suite of automated tools that stress test Netflix’s infrastructure and allow the company to proactively identify and resolve vulnerabilities before they impact customers.
Since then, Netflix has continued its commitment to automation and open source, and today engineers deploy code thousands of times per day. This year, Netflix was unanimously selected for the JAX Special Jury Award, with JAXenter editor technologies and implemented them into its DevOps approach is setting new standards in IT.”, “The rate at which this entertainment game-changer has adopted new
Inside, several groups have been evangelizing DevOps for years. According to , what “started out in small corners of development and infrastructure teams has since caught on like wildfire.”
He’s not exaggerating. These days DevOps not only powers the development of projects like, Target’s mobile savings app, but also has transformed the organization’s culture. Target now hosts DevOpsDays for its internal teams, featuring demos, open labs, lightning talks, breakout sessions, and guest keynotes. It also continues to spread the good word through the business community by sponsoring meetups.

Nordstrom’s customer mobile app team was the groundbreaker for its DevOps makeover. After surfacing the reasons behind mobile’s 22- to 28-week lead time, the team broke down the divide between dev and product support and organized squads around value. The company also migrated to continuous planning and moved to a single backlog of work. As a result, bugs went down, throughput went up, and releases went from twice per year to monthly. More importantly, Nordstrom realized these methods could work for any team, and it’s continuing to apply them across the organization.
helped about software development. Many of the tenets it adopted early on, including code ownership, incremental changes, automation, and continuous improvement, were DevOps in all but name. Its approach has matured over the years, and it recently to the Chef configuration management platform (and made some of its available to the public).
Facebook’s accelerated development lifecycle continues to reshape consumers’ expectations of software. Its recently announced bi-weekly app updates effectively served notice that constant, rapid refreshes for mobile apps are the new normal, and any company that can’t keep up risks getting left behind.
For its first several years,struggled with slow, painful site updates that frequently caused the site to go down. In addition to frustrating visitors, any downtime impacted sales for Etsy’s millions of users who sold goods through the online marketplace and risked driving them to a competitor.
With the help of a new technical management team, Etsy transitioned from its waterfall model, which produced, to a more agile approach. Today, it has a fully automated deployment pipeline, and its practices have reportedly resulted in more than with fewer disruptions. And though Etsy has no DevOps group per se, its commitment to collaboration across teams has made the company a model of the DevOps framework.

To maintain the required pace, Adobe uses CloudMunch’s end-to-end DevOps platform to automate and manage its deployments. Because it integrates with a variety of software, developers can continue to use their preferred tools, and its multi-project view allows them to see how a change to any one Adobe product affects the others.
The move has enabled faster delivery and better product management, and according to the Wall Street Journal, Adobe has already been able to meet(subscription required).

Digital Media Group (DMG) faced significant challenges delivering a software system to manage entertainment assets for end users. Manual processes and other hurdles typically resulted in a months-long delay between completion of software development and delivery.
To smooth out this “last mile,” DMG implemented an automated cloud delivery system composed of open source tools and SaaS solutions. Since adopting a continuous delivery model, DMG has cut down its months-long delivery time to just minutes. This allowed developers to focus on adding features and reduced idle resources and associated costs.
10. Fidelity Worldwide Investment
Like many enterprises,had several business units developing software applications and was burdened with legacy release processes that placed huge demands on its teams. Apps were deployed manually across hundreds of servers, with each app requiring customization. Manually introduced errors frequently broke the process.
When it came time to develop a critical trading application with a firm launch date, the organization knew its error-prone manual process would jeopardize the project. Fidelity used the opportunity to embrace a DevOps approach and implement ansoftware release framework that would enable it to meet the rollout schedule.
That solution resulted in more than $2.3 million per year in cost avoidance for that app alone. Since then, the Fidelity team has automated the release of dozens of applications, reducing release times from two to three days to one to two hours and decreasing test-team downtime. The process has also made it easier to display regulatory compliance and has enabled predictable release schedules that stakeholders can rely on.
