DevOps – What is it, and what’s in it for me? John Clapham
It seems everyone is talking about DevOps these days. Around six years after the term was first coined, practices; both technical and cultural, have evolved considerably. With this level of change, and considerable hype, it’s easy to lose sight of the fundamentals. This talk explains what DevOps has become today and its benefits (or sometimes otherwise) for individuals and organisations.
