What is DevOps?
DevOps is a combination of “Development” (Dev) and “Operations” (Ops). It is a culture, methodology, and set of practices aimed at bridging the gap between software development and IT operations. The goal of DevOps is to enable organizations to deliver applications and services faster, more reliably, and with higher quality.
In other words, DevOps integrates people, processes, and tools to automate software delivery and infrastructure changes, ensuring continuous development, continuous integration, continuous testing, and continuous deployment. It emphasizes collaboration between development, operations, and other stakeholders, fostering shared responsibility for the entire software lifecycle. DevOps also promotes a culture of monitoring, feedback, and continuous improvement, enabling teams to detect issues early, respond quickly to changes, and maintain high system availability and performance. By combining agile practices, automation tools, and cloud-native technologies,
DevOps helps organizations achieve faster time-to-market, reduced operational risks, and improved customer satisfaction.
