Lot has changed in the last 20 yrs. We have evolved from handcrafted server deployments to managing tens of thousands of devices programmatically, from monolithic architectures to distributed async-microservices, from waterfall to continuous delivery, from siloed culture to collaborative Dev*Ops culture and from hierarchical resource management to outcome-oriented structures. Still, organisations & teams struggle to keep up. In this talk, I explore why this happens and what organisations should do to build MUST required capabilities to run infrastructure operations at scale. Outline : * History, 20 yrs of change! * What does Infra-Ops Agility mean ? * Why organisations & particularly ops teams struggle? * What cultural, structural & skill aspects makes a great engineering org. ? * How to manage priorities ?
