The way data centers function has changed significantly over the past decade. Traditional, hardware-centric networking approaches are being replaced with software-driven, dynamic systems that can respond quickly to business demands. Companies today expect faster application delivery, stronger security, and reduced operational complexity. In response to these evolving requirements, Cisco developed two well-known solutions: Cisco Application Centric Infrastructure (ACI) and Cisco Nexus switches. While both are designed for high-performance data centers, their goals and methods differ. ACI emphasizes centralized, application-oriented network control, whereas Nexus focuses on delivering powerful, reliable switching hardware….
