Verplanke believes that DPDK (Data Plane Development Kit) and virtualization are key to virtualizing workloads that move around lots and lots of packets, such as firewalls, routers, and other similar functions. These challenges can be summarized as: I/O-intensive application virtualization. Intra-VM communication.

Anthony Burke (disclaimer: Anthony works for VMware in the NSBU) has a post on how to use Python to automate the bulk creation of firewall rules for use with the VMware NSX distributed firewall. Here’s a post by Grant Orchard on using VMware NSX’s security groups to protect workloads deployed via vCAC (now vRA).

Although I used to work at EMC before I joined VMware earlier this year , I never really had deep access to what was going on with this project, so my thoughts here are strictly based on what’s been publicly disclosed. Courteous comments are always welcome (but do please add vendor affiliations where applicable)!

I recently spoke at Interop 2016 in Las Vegas, and while I was there I scribbled down some notes pertaining to how decomposing applications into microservices-based architectures was similar in some respects to decomposing networks into an overlay network and an underlay (physical) network. Operating Systems/Applications.

For Carrier Ethernet, Cisco ME3600—a very expensive switch—will allow you to implement such an architecture. IPv4-only implementations include Nuage Virtual Services Platform (VSP) and Cisco Application Centric Infrastructure (ACI). VMware NSX has a stateful IPv6 firewall that provides RA guard and ND inspection services.

Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. Operating Systems/Applications. This tool exports the DFW configuration and then converts it into Excel format, and is available on GitHub. What’s that?

Vivek Gite over at nixCraft explains how to use ufw (Uncomplicated Firewall) on Ubuntu to limit SSH connections. Operating Systems/Applications. Flatpak is a (relatively) new application packaging/sandboxing mechanism for Linux applications. This looks really promising, IMHO—I’m excited to see it continue to develop.

After that talk Pat Gelsinger, CEO of VMware, takes the stage. Gelsinger then points out that although IT no longer controls the devices, the applications, or the networks, IT is still held responsible for security breaches. Gelsinger next brings Guido Appenzeller, CTSO of Networking and Security at VMware.
