Broadcoms decisions to replace perpetual VMware software licenses with subscriptions and to eliminate point products in favor of an expensive bundle of private cloud tools are driving longtime VMware customers to look for an exit strategy. There is no like-for-like replacement for the VMware hypervisor on the market, Delory points out.
But with the challenges surrounding Broadcoms acquisition of VMware and rumors of VMware customer defections , VergeIO has emerged as an alternative option. At the core of VergeIOs offering is its VergeOS platform, which takes a fundamentally different approach compared to traditional virtual infrastructure solutions like VMware.
It also delivers security services and solutions – including best-in-class firewalls, endpoint detection and response, and security information and event management – needed to address the most stringent cyber resiliency requirements. And throughout all of this, we enable them to draw on the VMware assets they know and trust.“

Ranga Maddipudi ( @vCloudNetSec on Twitter) has put together two blog posts on vCloud Networking and Security’s App Firewall ( part 1 and part 2 ). Some good advice here on scaling/sizing VXLAN in VMware deployments (as well as some useful background information to help explain the advice). Servers/Hardware. In vSphere 5.1,
Last week I had the opportunity to join John Troyer on the VMware Communities podcast. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February. Or virtualized firewalls?
The latter can be open-source software such as OpenStack, CloudStack or commercial products such as Citrix CloudPlatform or VMware Cloud Director (VCD). The user level elements that are managed within such an IaaS cloud are virtual servers, cloud storage and shared resources such as load balancers and firewalls. Firewall rules.
However, certain environments are inherently bound to hardware and/or tested for performance, and these may need to remain "in-house" on specific hardware (see below) Inherent application functionality N Apps that are inherently "internal" Such as internal back-up software, "edge" applications like printer servers, etc. Ken Oestreich.
VMware equates network virtualization to Server Virtualization. It streamlines server deployments because you can now deploy servers based on templates with almost no regard to the underlying hardware. I re-read the VMware post announcing the NSX product and it all kind of just clicked for me. Source VMware.
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. Devices first started as tightly-coupled hardware and software solutions. First, DPDK provides optimized pass-through support.
This post by Ranga Maddipudi shows you how to use App Firewall in conjunction with VXLAN logical networks. Next, Jason dives a bit deeper on the relationship between network overlays and hardware , and shares his thoughts on where it does—and doesn’t—make sense to have hardware terminating overlay tunnels.
Ben Fathi, CTO of VMware, takes the stage to start the keynote, and goes through a recap of yesterday’s announcements: EVO and EVO:RAIL, vCloud Air rebranding and the availability of new services, VMware Integrated OpenStack (VIO), and new product versions (vCloud Suite 5.8, betas of vSphere and VSAN).
Servers/Hardware. While all the attention is “up the stack,” there are still some occasions when you need to worry about the details in the hardware. Nice use of VMware Fusion in part 2, by the way.). VMware, Vagrant, and Docker together is the subject of this blog post by Fabio Rapposelli.
Kit Colbert (VMware Principal Architect) & Carl Ecshenbach (VMware COO) Joe Baguley (VMware CTO, EMEA). VMware is talking about the business of IT and how they enable their own business to deliver applications. VMware is of course pushing their virtual SAN solution (vSAN) to provision and control storage.
VM-to-VM (on the same host) via a hardware-based virtual switch in an SR-IOV network interface card (NIC). VMDq can provide a hardware assist when the hypervisor softswitch is involved, or you can use hypervisor bypass and SR-IOV to attach VMs directly to VFs (virtual functions). Note that there are trade-offs as a result.)

With server virtualization, you can easily create, move, and delete virtual servers as needed, without the need for expensive hardware upgrades or complex reconfigurations. One of the key benefits of server virtualization is that it allows for more efficient use of hardware resources.
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. You may have heard about the “6-pack”, Facebook’s new open modular hardware switch introduced recently ( here’s a post on it ).
Ivan Pepelnjak shares some links and thoughts on configuring the NSX-T firewall with a CI/CD pipeline built on GitHub Actions and Terraform Cloud. Servers/Hardware. Better patch your vCenter Server instances, as VMware released a security advisory with a long list of CVEs , including one with a severity score of 9.8/10.
Dmitri Kalintsev is back with another article in a series of articles on using hardware VXLAN tunnel endpoints (VTEPs) with VMware NSX. Here’s a handy post by Dale Coghlan on how to find object IDs for just about anything in a VMware NSX environment. Servers/Hardware. Networking. It’s about time.)
I recently came across a couple useful troubleshooting guides, one for Open vSwitch (OVS) and OpenStack Neutron and one for VMware NSX. Servers/Hardware. Russell Pope at Kovarus recently wrote about using security groups to manage the VMware NSX distributed firewall. VMware recently GA’d version 6.2 Virtualization.

A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. VMware introduced VMware NSX recently at VMworld 2013. Servers/Hardware. I am loving the micro-infrastructure series by my VMware vSphere Design co-author, Forbes Guthrie. Security.
” Speaking of Linux networking…Marek Majkowski of Cloudflare digs deep into conntrack , used for stateful firewalling functionality. Servers/Hardware. Duncan Epping walks readers through VMware Cloud Disaster Recovery , which—if I’m reading this correctly—is the evolution of the Datrium product.
In this post , Jakub Sitnicki digs way deep into the Linux kernel to uncover the answer to the question, “Why are there no entries in the conntrack table for SYN packets dropped by the firewall?” Servers/Hardware. This time, they’re exploiting a weakness that VMware can’t patch: people. Aye aye, Popeye!
Colin Lynch shares some details on his journey with VMware NSX (so far). I wouldn’t take this information as gospel, but here’s a breakdown of some of the IPv6 support available in VMware NSX. Servers/Hardware. This is a space that’s going to see some pretty major changes over the next few years, in my humble opinion.

This article by Joshua Fox outlines how and when to use each of the various types of firewalls offered by AWS. Servers/Hardware. From early December 2020, there’s also this reminder about the security updates released by VMware to address a zero-day vulnerability in several products. Thinking of buying an M1-powered Mac?
These protections are also expensive to implement in hardware. This bypasses some IPv6 limitations because host routes are treated in hardware like ND cache entries (which means you get something like 32K entries). VMware NSX has a stateful IPv6 firewall that provides RA guard and ND inspection services.
I think I’ve mentioned this before (it’s really hard to keep track of which articles you’ve included in a Technology Short Take already, so apologies if this is a duplicate), but this article provides a good overview of the VXLAN control plane modes in VMware NSX. Servers/Hardware. Keep up the great work, Brent!) Virtualization.

Tom’s key point is that disaggregating software from hardware—which is kind of a given if you’re buying whitebox networking gear—gives you the (potential) flexibility to repurpose network gear based on the software running on it. Servers/Hardware. However, it’s at least possible with whitebox networking gear. Virtualization.
Servers/Hardware. In the event you’re interested in an idea of how much latency the use of in-kernel hypervisor firewalling (such as that offered by VMware NSX) adds, have a look at this article by Sean Howard. It’s a good post, well worth reading (in my opinion). Nothing this time around. Maybe next time? Virtualization.
Servers/Hardware. specifically, the new container network firewall functionality. When I was using Fedora, I needed some useful information on firewall-cmd , and found this article to be helpful. I suppose this is fully expected, given the impact of VMware and hypervisors. Perhaps I should remove this section?
As devices are discovered, probes will also detect the services and hardware it can monitor. Reducing the costs by buying only the hardware you need. Detailed reports. What to Monitor. After the installation, PRTG will scan the network and auto-discovery will create sensors that are required to monitor it.
If you like geeking out over the hardware side of networking, you may find this Ars Technica article on the physical infrastructure of the global Internet to be an interesting read. (I Servers/Hardware. Hey, VMware Fusion/Workstation team—want to know why people seem to prefer VB over your technically-superior product?
