Netflix's migration to the cloud as our primary streaming control plane was paralleled by our move from traditional IT and centralized operations to a more decentralized DevOps organizational model. In this session, we explore the relationship between technical infrastructure and organization and how to find the right balance of centralized and decentralized operations. We also cover the rationale, goals, strategies, and technologies applied to accomplish this daunting task. We reflect on where we stand today and how we've realized many of our goals.
