\"Virtualization defined the previous generation of infrastructure modernization. The next era demands deeper integration and systemic control. Infrastructure as an Operating System is not a marketing abstraction. It is an architectural realignment that consolidates control, simplifies operations, and extends seamlessly from core datacenter to distributed edge. Enterprises that adopt this model move beyond incremental upgrades. They establish a programmable, autonomous foundation capable of supporting the next decade of digital transformation. The stack served its purpose. The operating system is what comes next.\"
