DevOps gets its name from the combination of development and operations in software development. therefore, you can easily guess a DevOps engineer is a skilled professional with expertise in IT operations and software development process.One such set of practices that have helped in development is DevOps Engineering. To shorten the software development lifecycle, it has undoubtedly shaped the future of modern development.What is DevOps?First introduced in 2007, the term is a combination of Software Development and IT Operations. DevOps essentially refers to a set of practices and principles that can help automate and integrate processes for streamlined software production processes. With the help of DevOps principles, development companies can shorten the software development life cycle, therefore delivering new software and its features or updates more frequently and reliably.DevOps guides cross-team communication and collaboration to help bridge the gap between the developers and the operations team. This removes the need for software and code to move between them in the development stage.In addition, it helps bring together testing, development, deployment, and operations of the software to achieve a continuous integration and continuous delivery (CI/CD) pipeline, ultimately leading to high revenue.Key Principles of DevOps EngineeringThe key principles or pillars of DevOps Engineering that guide improved development are as follows:Collaboration And CommunicationAs its name signifies, DevOps is based on continuous communication between the development and IT operations teams for a streamlined workflow. This enables the teams to share their expertise at every stage, leading to a better understanding.Working together also allows for corrections at an earlier stage, ensuring that the software doesn’t have to go through a back-and-forth cycle between the two teams. This makes problem-solving and innovation more efficient. Continuous IntegrationCI refers to automating the integration of code changes into a software project. Under this, the developers frequently merge code changes into a central repository where builds and tests are executed.Merging code makes the process easier to automate, which allows developers to extract common code and save time on repetitive tasks. In addition, by constantly updating code, the teams can easily address bugs, improve software quality, and increase the speed of software updates.Continuous DeliveryAn expansion of CI, continuous delivery aims to deploy code changes automatically to a testing or production environment. This helps test changes for error-proof software.A continuous delivery pipeline under DevOps involves automated and seamless builds, tests, and deployments. Together, CI and CID can help improve the rate of software release, enabling higher business success and ensuring the delivery of high-quality software at the same time. AutomationA core principle of DevOps, automation of tasks such as monitoring, testing, and deployment can help speed up the development process significantly. By helping reduce manual work, automation also helps minimize errors, increase team agility, and improve efficiency and consistency. Monitoring And Feedback DevOps promotes continuous monitoring and feedback at every development stage, including planning, development, integration and testing, deployment, and operations. This helps maintain the quality of the software. Continuous monitoring and feedback involve collecting data from different sources, such as end-user feedback, usage patterns, and system performance metrics. With a real-time insight into the software performance, the team can then introduce necessary updates and changes. Infrastructure As CodeAn essential practice in modern development, Infrastructure as Code (IaC) helps organizations automate the coding setup and management. As a result, IaC can help in scalability, reproducibility, and consistency. IaC involves managing computing infrastructure through machine-readable files to reduce human error. It also enables teams to automate monitoring and resource provision, helping save time.Agile DevelopmentAgile development practices refer to software development in small increments, which enables the teams to receive feedback and address issues quickly. This also helps the software development company meet the changing market needs promptly with improved flexibility for increased customer satisfaction. Advantages of DevOps in Software DevelopmentDevOps principles and tools play a significant role in the advancement of modern software development processes. About 99% of companies reported a positive impact of practicing DevOps in 2020. DevOps best practices can help with the following:Faster Time-To-MarketCI/CD, continuous monitoring and feedback, and task automation help DevOps ensure more frequent and faster software releases. This also enables businesses to keep up with changing market conditions and demands. In fact, the DORA 2019 State of DevOps report found that DevOps teams deploy software 208 times more frequently and 106 times faster than other teams.High-Quality SoftwareAutomated testing and deployment also help reduce the chances of human error, leading to higher-quality software. By detecting and fixing bugs in the early development process, companies can easily release software with minimal mistakes. This is supported by collaboration between operations and developers and continuous feedback and monitoring loops. In addition, automated testing and code deployment ensure the release of fault-free software. High SecurityDevOps also ensures software security by helping integrate protective measures from the early stages of the software development life cycle. DevSecOps is, therefore, an essential part of modern software development.Cost SavingsEnabling faster software development life cycles can save companies development costs in the long run. Moreover, optimizing the development process and introducing automation reduces the need for manual labor.DevOps also helps address bugs in the early stages, saving costs spent on addressing issues in released software. In addition, more frequent software releases lead to increased revenue. Lower RiskDevOps practices, through task automation and continuous monitoring and feedback, help identify risks and issues early on, ensuring the release of robust software. This leads to higher efficiency and a lower risk of major failures.ScalabilityWith the help of DevOps practices, companies can easily scale up software application development. Adopting a streamlined and automated process helps companies meet market demands.Who is a DevOps Engineer?DevOps engineers are skilled professionals who play a very important role today in the IT industry and operations teams.The key responsibilities of a Devops engineer are supporting a business with a technical approach, such as by integrating an environment of continuous delivery and improvement, streamlining IT operations, introducing Agile methodologies for high-quality product development and deliveries, and so on.The roles and responsibilities that DevOps engineers fulfill within an organization are crucial to achieving organizational goals and enhancing customer satisfaction.
