What Is DevOps?
DevOps is a cultural and technical movement that combines Development (Dev) and IT Operations (Ops) to streamline and improve the software delivery lifecycle. It aims to accelerate development, automate processes, and enhance the security and reliability of applications.
At its core, DevOps emphasizes:
Collaboration between developers, operations, and other stakeholders
Continuous Integration and Continuous Delivery (CI/CD) to automate testing and deployment
Monitoring and observability to detect issues early and ensure system health
Continuous feedback to improve product quality and team performance
By adopting DevOps practices, teams can deliver software faster, more reliably, and with greater agility.
