What is DevOps?
DevOps combines software development and IT operations to shorten the development lifecycle while delivering features, fixes, and updates reliably. It emphasizes collaboration, automation, continuous integration, continuous delivery, and infrastructure as code.
At its core, DevOps bridges the gap between teams who write code and teams who deploy and maintain it. Rather than working in silos with handoffs, DevOps teams share responsibility for the entire software lifecycle.
