Major Security Efforts
— Cisco and VMware
You can read this article by Ethan Banks that was written in early January here about the different software defined networking strategies from Cisco called ACI and from VMware called NSX. More documentation on ACI can be found here.
VMware announced NSX with a budding partner ecosystem, listing Arista, Brocade, Cumulus, Palo Alto Networks, Citrix, F5, Symantec, and several other vendors. None of their products yet incorporating NSX are available, but you can read this blog post about its features here and see a walkthrough demo of NSX here.
— AWS Security Groups
