There have been three major revolutions in data centers: virtualization, cloud computing, and Infrastructure as Code (IaC). IaC further automated infrastructure and increased scalability and collaboration, giving developers more responsibility. While this speeds innovation, it also raises security and governance concerns. New solutions aim to balance productivity and compliance by allowing self-service while simplifying governance through tools that govern environments according to policy with complete visibility and cost management. Looking forward, more such tools will support both productive developers and strong security.
