DevOps

As a core practice within modern Computer Science, DevOps represents a cultural philosophy and set of practices that integrate software development (Dev) and IT operations (Ops). The primary goal is to break down traditional organizational silos, fostering a culture of collaboration and shared responsibility to automate and streamline the entire software delivery lifecycle, from initial code commit to production deployment and monitoring. By employing principles like continuous integration, continuous delivery (CI/CD), and infrastructure as code, DevOps aims to increase an organization's ability to deliver applications and services at high velocity, improving upon traditional software development processes to ensure faster, more reliable, and more frequent releases.
