Virtualizing Business Critical Applications is often stopped either by the sudden involvement of security and compliance, a need to better understand, or a need to gain visibility into the underlying security of the virtual environment in order to build new security and compliance models.
While not particularly new news, the next version of the Cisco Nexus 1000v will be free, unless you want the security features. This is an interesting shift from Cisco with respect to VMware vCloud Director, the Nicira purchase, furthering UCS, and Cisco within non-UCS data centers. However, given other announcements, with respect to OpenStack, perhaps this is more a play to level the playing field between cloud architectures? But what I find most interesting, is that the changes to the Nexus 1000v also align with the changes we see in the vCloud Suites from VMware.
There are several improvements in virtual networking and security within the latest vSphere and vCloud products. vCloud Networking and Security lowers of the overall cost to implement endpoint security within a vSphere environment. VMware has accomplished this by including vShield Endpoint into vSphere. There by lowering the cost to offloaded antivirus and malware to just the product chosen to implement antivirus and antimalware.
