THE EMERGENCE OF SOFTWARE DEFINED NETWORKING
Software Defined Networking (SDN) is the physical separation of the network control plane from the forwarding plane, where the control plan manages several devices. SDN is a network architecture that is dynamic, cost effective, and adaptable, making it ideal for the high bandwidth, dynamic nature of modern digital applications. SDN enables the network control to become directly programmable while the underlying infrastructure is abstracted for applications and network services.
CISCO ACI FOR SDN
Cisco ACI is an industry leading SDN solution which helps customers manage complex environments through network automation.
Cisco IT automated their data centers with ACI, and achieved the following efficiencies:
- 25% reduction in capex (capital expenditure)
- 45% reduction in power and cooling cost
- 58% reduction in network provisioning time
- 21% improvement in network management costs
Cisco ACI can improve security for any combination of on-premise private and public clouds and data centers. Using ACI, customers increase business agility through network optimization, business protection, and cloud enablement.
CISCO NEXUS 9000 WITH ASIC
The Cisco Nexus 9000 series delivers proven high performance and density, low latency, and exceptional power efficiency in a range of form factors. These switches operate in Cisco NX-OS Software or Application Centric Infrastructure (ACI) modes with ground-breaking Cloud Scale Application-Specific Integrated Circuit (ASIC) technology. They are ideal to achieve a fully automated data center deployment.
CISCO APPLICATION POLICY INFRASTRUCTURE CONTROLLER (APIC)
The Cisco APIC is the unifying point of automation and management for your Application Centric Infrastructure (ACI) fabric. Cisco APIC provides a single point of access to all fabric information, optimizes the application lifecycle for scale and performance, and supports flexible application provisioning across virtual and physical resources.
