DevOps is a collection of methods, technologies, and a mindset that automates and integrates software development and IT teams' processes. Team empowerment, cross-team communication and collaboration, and technology automation are all emphasised. People working together to develop, produce, and deliver secure software at top speed is what DevOps is all about. Through automation, collaboration, rapid feedback, and iterative improvement, DevOps principles enable software developers (devs) and operations (ops) teams to expedite delivery.

What are the benefits of DevOps?

According to Atlassian's 2020 DevOps Trends study, 99 percent of respondents stated DevOps had had a positive impact on their company. Faster and easier releases, increased team productivity, increased security, higher quality products, and happier teams and customers are all advantages of DevOps.

  • Speed : DevOps teams produce deliverables more frequently, with improved quality and consistency. Elite teams deploy 208 times more frequently and 106 times faster than low-performing teams, according to the DORA 2019 State of DevOps study. Teams can use automated technologies to build, test, and deploy software using continuous delivery.
  • Improved collaboration : DevOps is built on a collaborative culture in which developers and operations teams share responsibilities and work together. This increases team efficiency and reduces time spent on job handoffs and writing code that is tailored to the environment in which it runs.
  • Rapid deployment : DevOps teams improve products quickly by boosting the frequency and velocity of releases. Quickly deploying new features and fixing bugs might give you a competitive advantage.
  • Quality and reliability : Continuous integration and delivery practises ensure that changes are functional and safe, improving the quality of a software product. Monitoring allows teams to stay up to date on performance in real time.
  • Security : DevSecOps is an active, integrated aspect of the development process because it integrates security into a continuous integration, continuous delivery, and continuous deployment pipeline. By incorporating active security audits and security testing into agile development and DevOps workflows, security is integrated into the product.

The DevOps lifecycle and how DevOps works?

The DevOps lifecycle begins with software development and continues with delivery, maintenance, and security. The following are the ten stages of the lifecycle :
  1. Manage : DevOps closes the loop by incorporating input and lessons learned throughout the lifecycle into your continuing iteration.
  2. Plan : DevOps lays out the work that has to be done, prioritises it, and keeps track of its progress.
  3. Create : DevOps writes code, makes modifications, and talks with coworkers about them.
  4. Verify : DevOps tests code automatically to ensure it is working properly.
  5. Package : DevOps keeps the software in a form that allows it to be reused in the future.
  6. Secure : DevOps uses static and dynamic tests, fuzz testing, and dependency scanning to determine whether the software includes vulnerabilities.
  7. Deployment : DevOps distributes software to end users.
  8. Configure : DevOps is responsible for the management of infrastructure and software platforms
  9. Monitor : DevOps looks at how software affects infrastructure and users. It also provides information to aid in the appropriate response to situations.
  10. Protect : DevOps ensures that the software's infrastructure is secure by ensuring that containers are up to date and locked down.

DevOps tools, concepts, and fundamentals

Across the application lifecycle, DevOps encompasses a wide range of approaches. Customers begin their journey to DevOps success with one or more of these approaches.

  • Source Code Management - Organizations searching for more efficient ways to coordinate changes to documents, software, photos, large web sites, and other collections of code, configuration, and metadata across multiple teams.
  • Agile Project & Portfolio Management - Teams seeking for a more efficient means of starting, planning, executing, controlling, and closing a team's work to fulfil particular goals and deadlines.
  • Continuous Integration (CI) - Teams searching for ways to automate the build and testing processes to ensure that code is consistently integrated and that tests are run frequently to reduce the amount of time spent manually running unit and integration tests.
  • Continuous Delivery (CD) - Teams seeking for automated techniques to develop, test, package, configure, and deploy programmes to a target environment.
  • Shift Left Security - Teams seeking for ways to uncover vulnerabilities during development and provide actionable information to enable developers to remediate vulnerabilities earlier in the lifecycle have defined goals and must satisfy particular success criteria by a certain date.
  • Monitoring and Feedback - Teams are searching for ways to incorporate monitoring into each deployed version, as well as the impact of application modifications on business value and user experience.
  • Rapid Innovation - Teams looking for ways to feed feedback back into the development, test, packaging, and deployment stages to close the loop and give real-time feedback from customers and production environments.

DevOps methodologies

DevOps is a direct descendent of agile software development, and it was formed out of the necessity to keep up with increased software development pace and productivity using agile approaches. DevOps emerged because of advances in agile development, which emphasised the need for a more holistic approach to the software delivery life cycle.

The term "agile development" refers to a number of iterative software development approaches, several of which have found their way into DevOps :
  • Scrum - a Framework for addressing complex adaptive challenges while providing the greatest possible value solutions.
  • Kanban - a method for organising product development that focuses on continuous delivery while minimising the development team's workload. Kanban, like Scrum, is a method for assisting teams in working together more efficiently.
  • Scaled Agile Framework (SAFe) - a set of organisational and workflow patterns designed to help businesses scale lean and agile processes. SAFe is one of a growing number of frameworks aimed at addressing the challenges that come with scaling beyond a single team.
  • Lean development - applying the concepts and practises of lean manufacturing to software development. Lean provides a conceptual framework, values, and principles, as well as best practises based on experience, to help organisations become more agile.
  • Extreme programming (XP) - is a software development process that aims to improve product quality and adaptability to changing client needs. XP promotes frequent releases with short iterations in order to boost productivity and offer checkpoints where new client requirements can be implemented. Other aspects of extreme programming include working in pairs or conducting extensive code reviews, unit testing all code, deferring programming of features until they are required, a flat management structure, code simplicity and clarity, anticipating changes in the customer's requirements as time passes and the problem becomes better understood, and frequent communication with the customer.

Who’s Adopting DevOps?

DevOps is making huge inroads into IT businesses all across the world, from early-stage startups to 100-year-old enterprises. According to one survey, 74 percent of businesses have adopted DevOps in some form.

What kinds of businesses are using DevOps? While web-native "unicorns" like Etsy, Facebook, Amazon, and Netflix are frequently identified as DevOps leaders, today's DevOps leaders include businesses of all sizes. Other DevOps success stories in the headlines include mainstream media business Sony Pictures, financial services behemoth Barclays Bank, and construction materials manufacturer USG.

Surprisingly, companies are leading the trend, with 81 percent saying that DevOps is being used in some capacity within their firm. DevOps is also proving beneficial to small and medium-sized organisations (SMBs), with 70% claiming to use it. Significantly, there is ample evidence that the size of an organisation is not a reliable indicator of DevOps success.

The US Patent and Trade Office switched to DevOps and now sees 1,000 automated builds each week on average. Production containers, automated workflows, and microservices are just a few of the ways the General Services Administration (GSA) is modernising its IT operations to deliver projects faster and with higher quality.
