In this episode we trace the history of the DevOps movement from its intersection with open source and Agile, through the evolution of Cloud technologies and tools such Docker and Kubernetes, to present day best practices for CI/CD, monitoring, and observability.

Dive in to learn what DevOps is, how to adopt it effectively at your organization, how developers can master scrum, what development framework to use, how to avoid ‘merge hell,’ and why the most important DevOps tool of all is beer.

Kris Buytaert is the Co-founder of Inuits, O11y, and ‘DevOps Days,’ an internationally-attended series of DevOps events. He is a passionate advocate of Free and Open Source Software, and is accredited by the community as being a founding instigator of the DevOps movement.
