Demo: End to end, hop by hop, physical and virtual network flow visibility with NSX

You’ve probably heard it before.  The myth goes something like this:  “With software based overlays, troubleshooting in real-time where a flow is going with ECMP hashing on the fabric is going to be a real problem.”  The implied message being that this can only be possible with special hardware in a new proprietary fabric switch. I’ve […]

An introduction to Zero Trust virtualization-centric security

This post will be the first in a series that examine what I think are some of the powerful security capabilities of the VMware NSX platform and the implications to the data center network architecture.  In this post we’ll look at the concepts of Zero Trust (as opposed to Trust Zones), and virtualization-centric grouping (as opposed to network-centric grouping). Note: […]

Networking is a Service, and you are the Service Provider

The status quo approach to Networking is the biggest barrier to realizing the full potential of Virtualization and the private, public, or hybrid cloud.  We must re-think how Networking *Services* are delivered, in a way that comports with automation, decoupling, pooling, and abstractions.  I would argue, the solution is a more software-centric approach — Network […]

New design guide: VMware NSX with Cisco UCS and Nexus 7000

New design guide: VMware NSX with Cisco UCS and Nexus 7000

Back in September 2013 I wrote a piece on why you would deploy VMware NSX with your Cisco UCS and Nexus gear.  The gist being that NSX adds business agility, a rich set of virtual network services, and orders of magnitude better performance and scale to these existing platforms.  The response to this piece was phenomenal […]
