For the second year in a row, in the SDxCentral NV Survey, VMware NSX was the vendor most often cited as being used or under evaluation by customers, followed by Cisco’s ACI/ Nexus switches/Intercloud/AVS. This is slightly different from industry analysis, which has indicated Cisco ACI is outpacing VMware NSX by about 2:1. (2).

SDxCentral’s Research Team took a look at the technology and solution announcements the leaders in this space made and the customer deployments they referenced this past year to try to understand some of the movements in the market. Our assessment is that the market is being driven by the “big four” — VMware, Cisco Systems, Juniper Networks and Nuage. In most major installations, these are the big NV players being considered. These companies also have announced the most customers.
While our own survey indicates that VMware is the leader with Cisco in the number two spot, we’ll note there is other research and data out there ranking the vendors in different orders, though the top four are almost always the same. For example, a recent IHS data-center study released this year ranked the top three as VMware, Nuage, and Cisco, in that respective order. (3)
To get more detail on what’s going on, the section below compiles recent activity by the big four.
