What is DevOps and Why You Should Care

DevOps will be seen as a tradition, motion, follow, methodology, set of instruments, and many others. However at its core, it’s a greater strategy to construct and deploy software program.

Software program and the Web have reworked the world’s industries throughout the board.

The consequence? Software program now not merely helps a enterprise, it’s turn out to be an integral element.

Simply as bodily items corporations reworked the best way they design, construct, and ship merchandise by way of industrial automation all through the nineteenth and twentieth centuries, corporations within the twenty first century should remodel the best way the construct and ship software program.

One such transformation taking the software program world by storm is DevOps.

However whilst DevOps continues to attain mass adoption throughout the software program growth panorama, confusion stays as to what precisely DevOps “is” (partially because of its historical past as a grassroots thought).

Is it a motion, a philosophy, a tradition, a follow, a strategy, or one thing in between? Does the that means of DevOps change in keeping with your function in a corporation?

Nonetheless you outline DevOps, reaping the advantages of this new method to the SDLC requires a metamorphosis and realignment of present cultures, roles, and processes. And that will help you alongside that journey, we’ve created this put up to assist introduce you to a few of the fundamentals.

What Is DevOps?

At its core, DevOps is a tradition, motion, and philosophy.

The phrase itself was coined in 2009 by Patrick Debois by way of his DevOps Days occasions, the purpose of which was to deliver collectively “growth” and “operations” practitioners who needed to resolve the clear challenges they confronted within the conventional siloing of their departments.

At present, DevOps has grown far past these preliminary (and ongoing) occasions, inspiring corporations worldwide to create multidisciplinary groups that work collectively by way of shared, environment friendly processes and instruments.

However DevOps is greater than a set of processes and instruments.

It’s a shift in mindset, a tradition, a motion that organizations and practitioners undertake to information them in direction of higher software program.

DevOps practices, guided by the core tradition and philosophy, automate processes between software program growth and IT administration groups to construct, take a look at, and launch software program quicker and extra reliably, in addition to enhance collaboration, communication, and belief inside a corporation.

We’ve got much more to say about DevOps, however discover this definition of DevOps from Gartner an important beginning place:

“DevOps represents a change in IT tradition, specializing in fast IT service supply by way of the adoption of agile, lean practices within the context of a system-oriented method. DevOps emphasizes individuals (and tradition), and seeks to enhance collaboration between operations and growth groups. DevOps implementations make the most of know-how — particularly automation instruments that may leverage an more and more programmable and dynamic infrastructure from a life cycle perspective.”

Historical past of DevOps

Even earlier than the preliminary DevOps days occasions, the DevOps motion started to take form round 2007 when IT operations and software program growth communities started to talk about what they felt have been deadly ranges of dysfunction of their trade.

Builders and IT Ops professionals had separate, conflicting targets and key efficiency indicators and siloed groups and management that resulted in lengthy hours, defective releases, and sad clients.

So that they started to rally in opposition to the standard software program growth mannequin that remoted those that write code from those that deploy and assist it.

Looking for a greater approach, individuals like Patrick Dubois, Gene Kim, and John Willis started driving the dialog in direction of merging these two disciplines for everybody’s profit.

However regardless of these grassroots origins, DevOps discovered precursors in two way more conventional IT disciplines:

  • Enterprise Techniques Administration (ESM): Many individuals concerned within the preliminary growth of the DevOps idea have been system directors who introduced key ESM greatest practices to DevOps, together with system monitoring, configuration administration, the toolchain method, and automatic provisioning.
  • Agile Improvement: As Ernest Mueller notes, DevOps will be seen as an outgrowth of Agile software program growth. Agile prescribes shut collaboration between product administration, builders, clients, and generally high quality assurance to quickly iterate higher merchandise. From this, DevOps acknowledges that “service supply and the way the app and methods work together are a elementary a part of the worth proposition” so “the product group wants to incorporate these considerations as a top-level merchandise… DevOps is just extending Agile ideas past the boundaries of the code to the whole delivered service.”

These precursors are particularly essential for enterprises, by which committing to the transformation of tradition and course of requires a excessive stage of diligence.

Somewhat than being a flash within the pan pattern with a number of “IT Geeks,” DevOps unites established IT operations disciplines with confirmed growth methodologies so growth and operations turn out to be a unified entity with frequent objectives – high-quality software program, high-speed releases, and excessive buyer satisfaction.

Why DevOps?

Builders and IT admins typically don’t see eye to eye. However each are inclined to agree that enterprise management typically pulls them in competing instructions.

To stay aggressive and rising, enterprise customers demand new options, companies, and income streams as quick as attainable.

On the similar time, they need secure methods, free from outages and interruptions.

This creates friction factors the place know-how groups have to decide on between delivering fast modifications then take care of unstable manufacturing environments, or preserve a secure however stale product atmosphere.

In fact, neither is appropriate to executives, and neither permits companies to supply the most effective options.

DevOps was created to resolve this dilemma by integrating all groups related to software program growth and deployment, from enterprise customers to builders, take a look at engineers, system directors, and safety engineers right into a consolidated, automated workflow.

Their shared focus: fast supply of high-quality software program whereas sustaining system integrity and stability.

That is enabled by a typical set of DevOps ideas adopted throughout conventional self-discipline boundaries and roles.

Examples of those ideas embrace:

  • Readability in expectations, priorities, and the core beliefs that information them.
  • Collaboration in problem-solving inside and between specialised groups.
  • Automation of frequent, repetitive processes.
  • Measurement and incorporation of suggestions throughout the SDLC.


Devops Advantages

In keeping with Puppet’s 2016 State of DevOps Report, excessive performing, DevOps centered IT organizations:

  • Deploy 200x extra regularly with 2,555x quicker lead instances.
  • Get well from failure 24x quicker with 3x decrease change failure charges.
  • Spend 22% much less time on unplanned work and rework and 29% extra time on new options and code.
  • Have extra loyal staff which are 2.2x extra more likely to advocate their group to colleagues as an important place to work.

Stats like which are spectacular sufficient to catch consideration, however significant change requires deep understanding – so let’s take an extra have a look at some key advantages of DevOps.

Quicker Launch Cycles

Within the fashionable IT atmosphere, pace is every little thing and groups that make use of DevOps greatest practices launch greater high quality, secure software program extra regularly.

In non-DevOps organizations, lack of automated take a look at and evaluation cycles sluggish the discharge cycle with guide testing, poor incident response instances, and due to these, a scarcity of group confidence. On the similar time, disparate, incompatible instruments and processes enhance operational bills and result in context switching that kills momentum and velocity.

By way of the traditional enterprise methods of standardization and automation, DevOps’ Steady Integration (CI), Steady Supply (CD), and Microservices practices allow groups to be extra productive, launch extra regularly with fewer errors, thus permitting elevated innovation at decrease prices.

By comparability, high-performance DevOps groups deploy on demand, a number of instances per day whereas low efficiency siloed groups deploy at greatest as soon as per 30 days – if not twice a 12 months.

Enhanced Reliability

Speedy supply charges are a hindrance if not paired with the reliability in manufacturing that finish customers anticipate. If vital points aren’t prevented or, at the least, resolved shortly, key points slip by way of the cracks – growing rigidity amongst groups and tanking buyer satisfaction.

The DevOps practices of CI and CD incorporate testing all through the SDLC to make sure every change is useful and protected, whereas full-stack monitoring and logging guarantee full transparency and detailed suggestions loops that speed up time to decision for any manufacturing errors that do come up.

All with out sacrificing a 3rd vital element to profitable software program – safety.

Utilizing automated compliance insurance policies, correct configuration administration, and fine-grained controls, excessive performing DevOps groups spend 50% much less time remediating safety points.

Efficient Scalability

Unplanned work is a actuality each IT group faces, one that may have a big impact on group productiveness if not correctly managed. Prioritizing unplanned work due to urgency and transitioning to that work throughout groups and methods is inherently inefficient.

DevOps groups set up environment friendly processes and clear prioritization whereas growing visibility and interesting in proactive retrospection to raised anticipate and share unplanned work – permitting them to attenuate the interruptions that forestall them from engaged on new, deliberate work.

By way of reductions in rework and unplanned work, in addition to automation and consistency, DevOps permits organizations to handle advanced, ever-changing methods to efficitently function and handle infrastructure at scale.

Deeper Collaboration

Cultural change is the first success consider DevOps adoption – successfully deploying DevOps requires constructing a tradition of shared duty, transparency, and quick, excessive constancy suggestions.

Groups that work in silos lose the advantages that DevOps’ “methods considering” – the attention of how one group’s actions have an effect on the opposite groups concerned within the launch course of – deliver. Lack of inter-team visibility and shared objectives results in a scarcity of dependency planning, conflicting priorities, and a finger pointing “not our downside” mentality that slows velocity and generates substandard high quality.

DevOps is a change in mindset that appears on the growth course of holistically, the place builders and IT operations groups carefully collaborate, share duties, and mix workflows to cut back inefficiencies, save time, and create a office crammed with happy, loyal staff.

How DevOps Works

A elementary element of the DevOps mannequin is that growth and operations groups are now not siloed.

Typically these two groups are merged, with engineers working throughout the applying lifecycle from growth to testing, deployment, and operations.

These DevOps groups automate sluggish guide processes and use know-how stacks that assist them function and evolve software program shortly and reliably.

Like all cultures, DevOps has many variations on its principal themes. Nonetheless, most observers and practitioners agree the next are frequent to most all DevOps practices.


In a DevOps tradition, growth and IT operations work collectively as an alternative of at odds. Nonetheless, DevOps extends past the IT group as nicely into different enterprise stakeholders together with product administration and executives, as these teams are integral to the management and administration that results in profitable software program.


DevOps closely emphasizes automation by way of a mixture of instruments. Instruments constructed internally, instruments bought externally, instruments tailored from open supply initiatives.

However whereas many DevOps instruments are extremely useful in and of themselves, it’s essential to keep away from the tendency to easily acquire a scattered set of instruments and name your group “DevOps.” These instruments should be built-in into toolchains that successfully automate giant elements of your specific end-to-end software program growth and deployment processes.

Steady Integration

As a result of DevOps emerged from Agile tradition, you’ll often discover Steady Integration (CI) is a key element of DevOps cultures.

In keeping with Aaron Cois, CI is a method designed to repeatedly merge “supply code updates from all builders on a group right into a shared mainline. This continuous merging prevents a developer’s native copy of a software program undertaking from drifting too far afield as new code is added by others, avoiding catastrophic merge conflicts.”

The Steady Integration precept forces builders to combine their work regularly (at the least each day) with the intention to expose integration points and conflicts as early as attainable.

Nonetheless, to attain the advantages in diminished rework and bug fixing time and prices, it’s important that groups depend on DevOps’ collaboration precept to make sure efficient communication.

Steady Supply

The DevOps group at Amazon Net Providers defines Steady Supply (CD) as a “software program growth follow the place code modifications are robotically constructed, examined, and ready for a launch to manufacturing.”

CD expands on Steady Integration by deploying any code modifications to both a testing or manufacturing atmosphere after every construct stage in order that builders are all the time working in direction of deployment-ready artifacts which have handed by way of standardized high quality management processes.

Launch frequencies in a Steady Supply mannequin can range tremendously relying on an organization’s legacy and objectives, with excessive performing DevOps organizations deploying a number of instances per day.

The precise definition of a “launch” varies as nicely, with some organizations sending code to QA first, the place modifications both go to customers, return to growth, or are usually not launched in any respect.

Different corporations push modifications immediately from builders out to customers and depend on their real-time monitoring and fast remediation processes to attenuate the affect of failures whereas decreasing the chance of great failures by retaining their replace sizes small.

Steady Testing

Whereas Steady Integration and Steady Supply get many of the consideration in DevOps discussions, testing is a vital element of a profitable DevOps follow. In a contemporary quick launch atmosphere, the operational value and consumer expertise affect of software program failures can shortly spiral uncontrolled.

In a DevOps tradition, Steady Testing (CT) isn’t only a High quality Assurance perform; gone are the times when builders might merely throw their code over the wall and anticipate QA to take care of any issues on their very own.

With DevOps, high quality is everybody’s job, with builders constructing high quality into their code and offering take a look at knowledge, whereas QA engineers configure automation take a look at circumstances and the testing environments.

On the operations facet, system admins guarantee monitoring instruments are in place and take a look at environments are correctly configured, and should even take part in a number of sorts of software program testing – offering suggestions and evaluation based mostly on take a look at outcomes and expertise operating manufacturing purposes.

CT is vital to a DevOps atmosphere because it helps organizations steadiness high quality and pace. Thorough testing ensures high quality whereas automated instruments and the follow of testing earlier within the SDLC reduces the time wanted and price of testing.

Steady Monitoring

Even in a well-automated QA atmosphere, the excessive launch velocity in a high-performance DevOps firm typically calls for offloading a few of the rigor of pre-release testing onto operations.

To take care of pace and high quality, failures should be discovered and stuck in actual time. That’s the place steady monitoring is available in.

With steady monitoring, DevOps groups enhance a manufacturing system’s stability by measuring the efficiency and availability of software program in actual time. This helps establish the foundation causes of breakages shortly, in addition to proactive prevention of outages to attenuate issues in end-user expertise.

Two key sorts of monitoring are employed in DevOps: server monitoring and utility efficiency monitoring.

Like testing, monitoring truly begins in growth in a DevOps atmosphere – the identical instruments that monitor manufacturing methods are employed throughout growth to establish efficiency issues earlier than deployment.


Microservices Structure is a design method the place a single utility is constructed as a set of smaller sub-services.

Every service runs its personal inside processes and communicates with different companies through a well-defined, light-weight interface – sometimes an HTTP-based Software Programming Interface (API), and every microservice is scoped round a single enterprise functionality.

Infrastructure as Code

Infrastructure as Code is a DevOps follow by which infrastructure is each provisioned and managed utilizing code and growth methods like model management and steady integration. Cloud-based infrastructure is nearly all the time integral to this course of.

Cloud’s API-driven mannequin permits each builders and system directors to programmatically work together with infrastructure at scale, changing the necessity to manually arrange and configure assets.

As a result of infrastructure and servers are outlined by code on this mannequin, assets will be shortly deployed and launched utilizing standardized patterns and up to date with the most recent releases in actual time.

Getting Began with DevOps

What started in on-line boards and native meetups has now turn out to be a serious pattern within the software program world. A decade into this DevOps experiment, the information is obvious: DevOps is right here to remain.

Core to that is that DevOps has succeeded in integrating enterprise customers, builders, take a look at and safety engineers, and system directors right into a single workflow that constantly and effectively meets buyer necessities.

And it’s seen vast adoption as a result of there’s one thing in it for all stakeholders.

Builders and sysadmins have stopped battling and began supporting one another.

Enterprise managers get high-quality software program services and products that promote.

Executives see buyer satisfaction and income steadily rising as their IT organizations align to ship the most effective buyer experiences attainable.

Outcomes like these, nonetheless, don’t come simply. Transitioning to DevOps requires a elementary change in firm tradition and worker mindset.

Taking the primary steps right into a DevOps transformation depend on an intensive examination of your present tradition and practices to establish boundaries to cross-team coordination and take the mandatory steps to bridge the hole between growth and operations groups.

DevOps is about eradicating the boundaries between the historically siloed growth and operations arms of a software program group. In DevOps, they work collectively to optimize the productiveness of builders and the reliability of operations.

Collectively, each attempt to speak regularly and take full possession of their companies past acknowledged roles and titles.

Whereas tradition is vital to DevOps transformation, figuring out the suitable instruments based mostly on the wants of your course of can be essential. Supply management, steady integration, automation, deployment, testing, infrastructure, and monitoring should all be thought of when constructing the suitable DevOps toolchain in your firm.

Attaining such deep, widespread change is a problem, DevOps transformations don’t occur in a single day and executives must be satisfied. That’s the dangerous information.

The excellent news is you don’t have to vary in a single day or watch for higher administration to log off on an organization-wide initiative. By working to assist your groups and leaders perceive the worth of DevOps whereas making small, incremental modifications, you may start to reap the advantages of a DevOps tradition immediately.

And also you don’t have to try this alone.

ATC makes a speciality of DevOps consulting to assist groups and corporations like yours handle the cutural and course of transformations concerned. We may also help you:

  • Audit your present processes, establish inefficiencies, align your group round a typical end-state imaginative and prescient, and create an actionable plan for implementing DevOps.
