Popular configuration management tools include Puppet, Chef and SaltStack. Today, DevOps focuses on the deployment of developed software, whether it is developed using Agile oriented methodologies or other methodologies. Continuous delivery expands upon continuous integration by automatically deploying code changes to a testing/production environment. It follows a continuous delivery pipeline, where automated builds, tests, and deployments are orchestrated as one release workflow. DevOps solves communication and priority problems between IT specializations. To build viable software, development teams must understand the production environment and test their code in realistic conditions.
Version Control
As with software development, it how to be a devops engineer is far easier to transform a single stream with a small group of stakeholders than to attempt an all-at-once organizational transition to a new way of working. By increasing the frequency and velocity of releases, DevOps teams improve products rapidly. A competitive advantage can be gained by quickly releasing new features and repairing bugs. Quickly identify and resolve issues that impact product uptime, speed, and functionality. Automatically notify your team of changes, high-risk actions, or failures, so you can keep services on. A key aspect of DevOps is learning from real-world performance and using that feedback to improve future releases.
Consider the workflows
- DevOps is an approach to working that emphasizes the quick, incremental, and continuous delivery of products.
- Unlike a source code repository, a binary repository stores packaged outputs, such as libraries and executable files, to be reused in other phases of the development lifecycle.
- Started in the early 2000s at Google, it’s a programming- and automation-focused approach to the software development lifecycle.
- Additional benefits of a DevOps culture include improved team efficiency, increased release speed, and better feedback mechanisms.
Automated testing helps ensure the quality and reliability of software and infrastructure updates. With microservices, separate teams can work on different components of new releases concurrently to speed development cycles. This approach drives continuous improvement, innovations and bug fixes to market sooner. Because of this ability to speed software delivery, reduce costs and improve security postures, many organizations are now adopting DevSecOps as a standard approach to DevOps. The release stage is the last workflow before users access the application. This stage includes a series of final tests to ensure that the software meets quality, compliance and security standards and is ready for external use.

Agile is an iterative approach to project management and software development that helps teams break work into smaller pieces to deliver incremental value. In big enterprises, software deployment tends to reside in the hands of high-level IT pros who manage the IT infrastructure, but the build-out of software is in the hands of a code-focused team working in a staging environment. With the increased need for companies to get their solutions built and released quickly as well as managed effectively and securely, some businesses have begun to see inefficiencies in this traditional division of tech labor. Additionally, monitoring tools enable DevOps professionals to observe the performance and security of code releases on systems, networks and infrastructure.
- A DevOps culture is where teams embrace new ways of working that involve greater collaboration and communication.
- This stage includes a series of final tests to ensure that the software meets quality, compliance and security standards and is ready for external use.
- AI can identify security vulnerabilities in applications and infrastructure, and scan event logs to detect potential threats in real time.
- Initially, DevOps can mean a commitment from development and IT operations teams to understand the concerns and technological boundaries that exist at each stage of the software project.

For example, an organization can use HashiCorp Terraform or CloudFormation to make IaC templates for its AWS workloads. Version-controlled source code repositories enable multiple developers to work on code. Developers check code out and in, and they can revert to a previous version of code if needed. These tools keep a record of modifications made to the source code — including who made the changes and when. Without tracking, developers might struggle to follow which changes are recent and which versions of the code are available to end users. However, CD typically stops with the mechanical aspects of code creation.
If errors or defects are found, the team has a chance to intercept and remediate any problems before users see them. When all issues are fixed and the application meets all requirements, it can be released to the production environment. Atlassian offers an Open DevOps solution that provides end-to-end DevOps processes with Atlassian and other third-party tools. With Jira as the backbone, teams can use Atlassian products or bring their favorite products to the open toolchain. The Atlassian ecosystem offers a robust array of integrations and add-ons, allowing teams to customize their toolchain to meet their needs.
The CI/CD pipeline helps automate core software development tasks such as integrating code, testing code quality, compiling and packaging code and deploying software. The foundation of DevOps is a culture of collaboration between developers and operations teams, who share responsibilities and combine work. This makes teams more efficient and saves time related to work handoffs and creating code that is designed for the environment where it runs. 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. Mobile DevOps is a set of practices that applies the principles of DevOps specifically to the development of mobile applications.
CD methodologies involve a frequent cyclical pattern of building and committing code changes to a central repository. The code can then be tested and validated using automated and manual testing technologies. If testing is successful, the build can be considered for release to production. DevOps continues to evolve, as artificial intelligence surfaces to aid in everything from code creation to incident management. AI for DevOps (or AIOps) means smarter automation and even shorter wait times, even seamless translations from business need to technological offering — but plenty of barriers remain before AIOps becomes reality. Vendors touted DevOps-enabling capabilities in tools, from collaboration chatbots to CI/CD suites built into cloud services.
The hallmarks of DevOps are continuous integration and continuous delivery (CI/CD), which support smaller, faster software updates. With CI/CD, small chunks of new code are merged into the code base at frequent intervals, and then automatically integrated, tested and prepared for deployment to the production environment. Practices like continuous integration and continuous delivery ensure changes are functional and safe, which improves the quality of a software product. Continuous integration (CI) allows multiple developers to contribute to a single shared repository. When code changes are merged, automated tests are run to ensure correctness before integration.
Metrics, logs, traces, monitoring, and alerts are all essential sources of feedback teams need to inform their work. Continuous integration is the practice of automating the integration of code changes into a software project. It allows developers to frequently merge code changes into a central repository where builds and tests are executed.
A DevOps approach is one of many techniques IT staff use to execute IT projects that meet business needs. DevOps can coexist with Agile and other continuous software development paradigms; IT service management frameworks, such as ITIL; project management directives, such as Lean and Six Sigma; and other strategies. Site reliability engineering (SRE) and DevOps are complementary strategies in software engineering that break down silos and lead to more efficient and reliable software delivery. DevOps teams focus on making updates and deploying new features while SRE practices protect the reliability of systems as they scale. At the technical level, DevOps requires a commitment to automated tools that keep projects moving within and between workflows. For example, automated testing, deployment and provisioning of infrastructure components can help accelerate project delivery and reduce errors.
During this workflow, they draw on user feedback, case studies and inputs from internal stakeholders such as platform and infrastructure engineers, security, compliance, governance, risk management and line-of-business teams. The DevOps lifecycle is designed to optimize the rapid delivery of high-quality software. It includes a series of iterative, automated workflows that run within a larger automated and iterative development lifecycle.
