What Is DevOps? Definition, Goals, Methodology, and Best Practices

Below we’ll survey key DevOps concepts, and identify entry points for adopting a DevOps culture in your own organization. Bring data to every question, decision and action across your organization. While DevOps is considered a mindset first, there are several DevOps tools used to automate various stages in a DevOps process. This practice involves the participation of the Operations team who will monitor the user activity for bugs or any improper behavior of the system. After the code is developed, then you move to the Continuous Integration phase.

What is DevOps

DevSecOps emerged as a specific effort to integrate and automate security as originally intended. In DevSecOps, security is a “first class” citizen and stakeholder along with development and Operations, and brings security into the development process with a product focus. It’s generally accepted that DevOps methods can’t work without a commitment to DevOps culture, which can be summarized as a different organizational and technical approach to software development. It also supports consistency, reliability, and efficiency within the organization, and is usually enabled by a shared code repository or version control. As DevOps researcher Ravi Teja Yarlagadda hypothesizes, “Through DevOps, there is an assumption that all functions can be carried out, controlled, and managed in a central place using a simple code.”

Relationship to other approaches

With continuous delivery, new code is tested and staged via an automated process so it’s ready to be deployed. Essentially, the agile movement led software design and construction to become more flexible — but it didn’t cover the entire software development lifecycle into the deployment stage. Apart from these common components of the DevOps lifecycle, there exist several other phases as well like the continuous testing phase , security phase etc.

Team members need to be alerted of failures in the deployment pipeline — whether systemic or due to failed tests — and receive timely updates on the health and performance of applications running in production. Metrics, logs, traces, monitoring, and alerts are all essential sources of feedback teams need to inform their work. Moving from a legacy infrastructure to using Infrastructure as Code and microservices can offer faster development and innovation, but the increased operational workload can be challenging. It’s best to build out a strong foundation of automation, configuration management, and continuous delivery practices to help ease the load. DevOps teams use tools to automate and accelerate processes, which helps to increase reliability.

See how we work with a global partner to help companies prepare for multi-cloud. While multi-cloud accelerates digital transformation, it also introduces complexity and risk. He uses the blog as a vehicle for sharing tutorials, writing about technology and talking about himself in the third person. It’s not a programming language, or even a particular software architecture pattern. So you could think of DevOps as being an area of interest, or a field of expertise, not a fixed process or a list of tools.

What is DevOps

However, the combination of microservices and increased release frequency leads to significantly more deployments which can present operational challenges. Thus, DevOps practices like continuous integration and continuous delivery solve these issues and let organizations deliver rapidly in a safe and reliable manner. Infrastructure automation practices, like infrastructure as code and configuration management, help to keep computing resources elastic and responsive to frequent changes. In addition, the use of monitoring and logging helps engineers track the performance of applications and infrastructure so they can react quickly to problems.

They should understand that they have an equal stake in the final outcome. In the DevOps paradigm, passing of work from one team to another is completely defined and broken down. This accelerates the entire process of development since collaboration between all the teams involved is streamlined. Teams entrenched in siloed ways of working can struggle with, or even be resistant to, overhauling team structures to embrace DevOps practices. Some teams may mistakenly believe new tools are sufficient to adopt DevOps. Everyone on a DevOps team must understand the entire value stream — from ideation, to development, to the end user experience.

It’s an alignment of people, processes, and tools toward a more unified customer focus. Multidisciplinary teams take accountability for the entire lifecycle of a product. Adopting DevOps first requires a commitment to evaluating and possibly changing or removing any teams, tools, or processes your organization currently uses.

What is DevOps

A DevOps team includes developers and IT operations working collaboratively throughout the product lifecycle, in order to increase the speed and quality of software deployment. It’s a new way of working, a cultural shift, that has significant implications for teams and the organizations they work for. But NetApp doesn’t just make it easy for developers to consume storage as code. NetApp technology also allows operations to confidently provision and deliver resources to development and testing personnel.

DevOps and site reliability engineering (SRE)

DevOps deployment is increasing in enterprise companies and the centralized or monolithic methods of project management like Spiral and Waterfall are decreasing. The DevOps movement is being led by the proliferation https://globalcloudteam.com/ ofmicroservicesthat complex business organizations need to support. The main concern of both startups and enterprise corporations is to advance software development more quickly with better security.

  • Monitoring feature performance, behavior, and availability ensures that the features are able to provide value add to end users.
  • The latest code is inserted into a shared space in which an automated build tests changes and validates them.
  • During this time, teams would work on several major features, generally involving large chunks of code that made a considerable impact on the software as well as its codebase.
  • Developers are required to maintain their code, so they can fix incidents in less time and are motivated to make their software more reliable.
  • The waterfall method involved the software development teams working on feature development and bug fixes over product development phases that spanned over a period of several months.
  • At its most successful, DevOps is a combination of specific practices, culture change, and tools.

DevOps customers including Capital One, IHG, Autodesk, Mabl and a host of others can attest to their DevOps transformations using CloudBees products. See what they’ve done by reading theircase studiesand decide on whether deploying a DevOps model is best for you. Simply put, companies that have embraced DevOps are better positioned to solidify their position in existing markets and expand into new ones. Indeed, adopting DevOps is rapidly becoming the de facto standard for software development. A quicklook at industry examples– think Apple, Netflix, Tesla, Uber, AirBnB and many others – reveals early successes and tremendous potential. Andrea C. Crawford is a Distinguished Engineer at IBM with expertise in classical and modern DevOps.

These projects require months, even years of consistent efforts by large teams of people from both technical and non-technical backgrounds. And therefore naturally, this process involves some challenges of its own that any organization has to face. There are, however, core principles or best practices around architecture in DevOps organizations.


It requires breaking down silos in order to collaborate throughout the product lifecycle. The DevOps lifecycle consists of eight phases representing the processes, capabilities, and tools needed for development and operations . Throughout each phase, teams collaborate and communicate to maintain alignment, velocity, and quality. The DevOps approach focuses on iterative and incremental improvements over the software’s stability and reliability, which often involves working on the system-related problems over several sprints before the problem is solved. On the other hand, the SRE approach to problem-solving is fixing the system-related issues in a way that they never show up again, prioritizing the application’s reliability over feature additions. The automation tools used by both DevOps and SRE development methods are almost the same.

What is continuous integration in DevOps?

DevOps tools 🔨 – Any software tools that make it easier to collaborate and deploy software. Coding and operation teams have their separate timelines and are not in synch, causing further delays. The DevOps is the combination of two words, one is Development and other is Operations. It is a culture to promote the development and operation process collectively. Service-operating teams should be able to configure monitoring and alerting.

While teams were working on, say, feature A, there was a possibility that a competitor released another app during the same time with feature B that the customers liked better. The output in such a scenario would have been a devastating project failure. Serverless functions are part of an evolution in cloud computing that has helped free organizations from many of the constraints of managing infrastructure and resources.

Many such tools also promote core DevOps tenets of automation, collaboration, and integration between development and operations teams. The following shows a sample of tools used at various DevOps lifecycle stages. Continuous deployment is the process of automating the release of new code as it’s integrated and approved through continuous integration and continuous delivery. Code that’s successfully tested through the automated delivery processes is staged and released into the production environment, making the new feature immediately available to end users.

Auditability of compliance measures is extremely important for proving compliance to 3rd party auditors. Integration (or build, or continuous Integration and continuous delivery (CI/CD).As noted above, in this workflow the new code is integrated into the existing code base, then tested and packaged into an executable for deployment. Common automation activities include merging code changes into a “master” copy, checking out that code from a source code repository, and automating the compile, unit test and packaging into an executable. Best practice is to store the output of the CI phase in a binary repository, for the next phase. DevOps speeds delivery of higher quality software by combining and automating the work of software development and IT operations teams.

Operations.If getting features delivered to a production environment is characterized as “Day 1”,then once features are running in production “Day 2” operations occur. Monitoring feature performance, behavior, and availability ensures that the features are able to provide value add to end users. Operations ensures that features effects of remote work on devops are running smoothly and that there are no interruptions in service – by making sure the network, storage, platform, compute and security posture are all healthy! If something goes wrong, operations ensures incidents are identified, the proper personnel are alerted, problems are determined, and fixes are applied.

Continuous integration involves regularly adding new code to a product’s main source code when tasks are completed. The latest code is inserted into a shared space in which an automated build tests changes and validates them. This gives developers feedback immediately and allows them to make changes to fix issues without delay. Developing software involves creating code to power applications, and IT operations focuses on bringing those applications to end users with any maintenance necessary. The best automation tools in the industry are proprietary and are often made available via the software as a service delivery system. These platforms and tools tend to be expensive, and hence full-scale use of DevOps methodology can result in exorbitant project development costs.

Code repositories should integrate with CI/CD, testing and security tools, so that when code is committed to the repository it can automatically move to the next step. Checking the code statically via static application security testing is white-box testing with special focus on security. Depending on the programming language, different tools are needed to do such static code analysis. The software composition is analyzed, especially libraries and their versions are checked against vulnerability lists published by CERT and other expert groups.
