5 minutesDevOps, one of the most effective organizational approaches used in the IT industry today, has evolved into many related methodologies that focus on specific aspects of software or types of applications. DevSecOps or Development Security Operations is one of these concepts.
How are these two approaches related and what are their differences? The answer to this question as well as the explanation of the relationship between DevOps and other IT concepts can be found in this article.
DevSecOps is a concept related to DevOps that focuses on integrating security practices into all steps of the development and delivery processes. DevSecOps emphasizes the accountability of everyone involved in the process of building and delivering software.
Similar to DevOps, DevSecOps favors automation over manual work, especially in testing, and promotes continuous learning. Despite these similarities, a DevOps team may not focus on security to the extent that DevSecOps teams do.
DevOps accelerates the development process, optimizes the production environment, and promotes continuous delivery. It also aims to increase infrastructure and application stability and reliability by boosting software scalability.
DevSecOps can significantly improve security throughout the development lifecycle, reducing remediation costs and improving compliance with industry standards. Along with proactive threat detection, it increases customer confidence in the software and company.
DevSecOps can be successfully integrated into DevOps processes. It requires a thorough security assessment, appropriate training, the implementation of security standards, and the adoption of \"shift-left\" security, which aims to resolve potential security issues as quickly as possible.
Automated security monitoring and testing, secure configuration management, close collaboration with security teams, and continuous training and improvement are also key components of the transformation.
To better understand DevOps, it is useful to compare this concept with other terms that are widely used in the IT industry.
Continuous Integration/Continuous Deployment (CICD) is one of the most essential components of the DevOps approach, which focuses primarily on automated code integration, testing, and deployment. It supports the iteration of the development cycle and facilitates merging changes with the existing code base.
Infrastructure is one of the most central components of DevOps work. It is the underlying network, software, and hardware required to run services and applications, and can include storage, network devices, databases, operating systems, and more.
MLOps, or Machine Learning Operations, can be considered an extension of the DevOps methodology, focused primarily on the adoption of the DevOps methodology for the development and deployment of machine learning software.
Systems Operations (SysOps) is a fairly narrow specialization that focuses on the maintenance and management of systems and infrastructure used to run the software used by an organization. SysOps specialists can integrate DevOps practices into their work to make it more efficient.
GitOps is a methodological approach that revolves around Git as a central tool for managing applications and infrastructure. GitOps promotes a declarative definition of the desired states of application and infrastructure components by borrowing and enhancing some of the DevOps practices related to continuous deployment and infrastructure management.
IT Operations (ITOps) is the traditional approach to software development and deployment as opposed to the DevOps culture. There is a large gap between the two approaches, as ITOps supports the separation between development and operations teams and enforces a formal way of managing changes to applications and infrastructure. It was also known for its reactive approach and heavy reliance on manual processes.
SDLC stands for Software Development Life Cycle. SDLC is an approach to software development in which all required activities are divided into structured steps that often have a linear sequence. Typically, these steps are project requirements gathering, design, testing, deployment, and maintenance phases.
Although SDLC and DevOps are two different concepts, their approaches to software development can be compared to each other. DevOps prefers the Agile method, which is known for its iterative and incremental methodology, while one of the SDLC methods is Waterfall, which is linear and sequential.
DevOps are often engaged in working on cloud-based projects. This requires close collaboration with cloud engineers who specialize in designing, building, and deploying cloud-architected applications. To make cloud software delivery more efficient, many cloud engineers adopt DevOps best practices and become cloud DevOps engineers. However, initially, cloud engineers do not necessarily work with DevOps methodology, although it is very effective. We described that with dedicated article there: CloudOps vs DevOps
DevSecOps and DevOps are closely related concepts, even though there is also a strong difference between them. Despite the similar emphasis on automation and continuous learning, there is a distinction between the application domains. DevOps is a broader approach that applies to various tasks in the deployment and development pipeline, while DevSecOps addresses the security aspects of software development.
