Software development teams often view software security as an afterthought, something that can be added on after the product is fully functional. Although this approach may have made some sense in the past, today it's largely seen as a mistake since it can lead to unanticipated vulnerabilities in released code. DevOps provides a mechanism for change and enforcement when it comes to security. DevOps practitioners should find it natural to integrate a security focus into development iterations by adding security tests to their continuous integrationprocess. Continuous integration is the practice of merging all development versions of a code base several times a day. This practice provides the same level of automated enforcement for security attributes as for other functional and non-functional attributes, ultimately leading to more secure, robust software systems.
In a previous post, we defined DevOps as ensuring collaboration and integration of operations and development teams through the shared goal of delivering business value. Typically, when we envision DevOps implemented in an organization, we imagine a well-oiled machine that automates
Ultimately, these practices are a result of applying DevOps methods and tools. DevOps works for all sizes, from a team of one to an enterprise organization.
Melvin Conway, an eminent computer scientist and programmer, create Conway's Law, which states: Organizations that design systems are constrained to produce designs which are copies of the communication structures of these organizations. Thus, a company with frontend, backend, and database teams might lean heavily towards three-tier architectures. The structure of the application developed will be determined, in large part, by the communication structure of the organization developing it. In short, form is a product of communication.
A DevOps approach must be specifically tailored to an organization, team, and project to reflect the business needs of the organization and the goals of the project.
Software developers focus on topics such as programming, architecture, and implementation of product features. The operations team, conversely, focuses on hosting, deployment, and system sustainment. All professionals naturally consider their area of expertise first and foremost when discussing a topic. For example, when discussing a new feature a developer may first think "How can I implement that in the existing code base?" whereas an operations engineer may initially consider "How could that affect the load on our servers?"
DevOps is a software development approach that brings development and operations staff (IT) together. The approach unites previously siloed organizations that tend to cooperate only when their interests converge, resulting in an inefficient and expensive struggle to release a product. DevOps is exactly what the founders of the Agile Manifesto envisioned: a nimble, streamlined process for developing and deploying software while continuously integrating feedback and new requirements. Since 2011, the number of organizations adopting DevOps has increased by 26 percent. According to recent research, those organizations adopting DevOps ship code 30 times faster. Despite its obvious benefits, I still encounter many organizations that hesitate to embrace DevOps. In this blog post, I am introducing a new series that will offer weekly guidelines and practical advice to organizations seeking to adopt the DevOps approach.
