In the second part of this series examining vendors' SDN products, I look at Cisco ACI, Arista's programmable approach, and HP's commitment to OpenFlow.
In the first part of this series on vendors' software-defined networking (SDN) strategies, I discussed the SDN landscape and the most recent InformationWeek SDN Survey, which showed that most vendors have a long way to go when it comes to explaining their SDN plans. In this post, I'll examine SDN products from Cisco, Arista, and HP.

That changed in November when the company announced its Application Centric Infrastructure (ACI), a grand blueprint that goes beyond low-level flow control and virtual network management to include enterprise-wide regulation and automation of application use, performance and security policies, orchestration of virtual network services, and management of physical and virtual network configuration.

Who among us has mastered provisioning resources in different clouds; allocating the right resources to each application; assigning applications to the "best" cloud provider based on performance or reliability requirements.
