Just like the Industrial Revolutions of the late 18th and early 20th centuries irreversibly changed methods of production, DevSecOps has transformed the way that applications are built and deployed in today’s market. By removing the barriers between once siloed and isolated teams, DevSecOps seeks to reach a state of continuous integration and delivery (CI/CD), streamlining efforts to simplify testing, increase security, and dramatically shorten time to launch.
What is DevSecOps?
In order to understand DevSecOps, we must first look at the legacy architecture of siloed teams. In a traditional siloed operating environment, the application developers, application administrators, and security team all worked in isolation, focusing on their individual goals. The app developers would focus on the functionality and mechanics of the application, the app administrators would concentrate on proper testing and deployment, and the security team would sweep through to make sure there weren’t any vulnerabilities before the product was launched. This process was inefficient and time-consuming, but it worked for many years in an environment where updates were only pushed once a quarter or less. In recent years however, the demand for more frequent updates and iterations has led to an increase in the ratio of developers to administrators, creating a bottle neck at the deployment stage. Enter DevSecOps. DevSecOps breaks down the walls between teams, encouraging intense collaboration from development to testing and deployment.
What is the significance of DevSecOps?
The driving force behind the adoption of DevSecOps is the desire to achieve continuous integration and continuous delivery (CI/CD), allowing teams to launch code changes more frequently and reliably. This has been made possible by the adoption of Infrastructure as Code (IaC)—the practice of writing code that describes your infrastructure at a high level in order to rid deployments of manual steps and automate them in the script. Similar to how the cotton gin eliminated the need for manual seed separation, leading to exponential scalability in cotton production, DevSecOps automates once-tedious manual steps to streamline processes and increase productivity. Achieving CI/CD through DevSecOps means that teams can make frequent but small updates, allowing them to identify bugs, minimize vulnerabilities, and deliver features more quickly.
The Culture of DevSecOps
DevSecOps also represents a culture shift within an organization, whereby teams are composed of diverse, cross-functional members in an environment that fosters creativity, teamwork, and opportunities for professional growth. When Henry Ford invented the assembly line in 1913, he invited product specialists from each stage of the production process to put their heads together and re-envision how automobiles were made from start to finish. DevSecOps seeks to do the same: with built-in and executable actions for version control, testing, small deployments, and security checks, anyone on the team is able to engage with the product at any point in the development stage. The bottom line is that companies that incorporate DevSecOps can deliver cutting-edge products with maximum speed, while engaging employees and fostering innovation.
The future is DevSecOps
The Industrial Revolutions of yore witnessed a fundamental shift in how goods were produced by using machines to automate once-manual tasks, resulting in increased safety, efficiency, and scalability. DevSecOps has done the same thing for digital products by automating through code and revolutionizing application development. According to a study published by DZone, 52% of companies have already introduced a DevSecOps approach to some products, and 30% intend to do so in the next 2 years.* The results are clear: the future is DevSecOps.
