Learning NSX SD-WAN by VeloCloud – Orchestrator Configuration Basics

June 11, 2018 / Martijn / 0 Comments

This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. In an earlier post, I explained the concepts behind the architecture of NSX SD-WAN and with this post, I will dive into the VeloCloud Orchestrator (VCO) to see what you need to configure to generate an SD-WAN network. Please note that the Orchestrator can be used to monitor and troubleshoot the SD-WAN as well, I will cover those topics in a future post.

VeloCloud Orchestrator (VCO) – What is it?

The VCO is the management … Read more

NSX-v 6.4.1 Released – Extended HTML5, vSphere 6.7 support & more

May 25, 2018 / Martijn / 2 Comments

NSX for vSphere 6.4.1 has been released and it brings a couple of good nuggets. Most of all, it is now compatible with vSphere 6.7 – so if you want to go to vSphere 6.7 and NSX was holding you back, start your upgrade engines!

HTML5 UI Extended

It fills me with joy to see this happening – 6.4.1 brings a bunch of new functionality to the HTML5 UI instead of the old vSphere-Client UI. The additions are:

Distributed Firewall Management
The Service Composer: Security Groups, Policies and Tags.
SpoofGuard Management
IPFIX Configuration & Flow Monitoring
Groups & Tags: all

Learning NSX SD-WAN by VeloCloud – The Basics

May 8, 2018 / Martijn / 10 Comments

This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. I’ve had the privilege to play around with the virtual appliance for a couple of months with a physical appliance on the way. Expect more details in this series. ?

The upcoming chapters are building up the components that are in the VeloCloud portfolio and the components that you need to know.

Edge Appliances

An Edge Appliance is a physical or virtual appliance which is in the data path of your network traffic. It typically … Read more

Storing the VMware NSX config in version control

April 30, 2018 / Martijn / 4 Comments

Almost any organization that I’ve had the pleasure of talking with, uses Git either for code repositories where their developers work or for doing version control on their infrastructure systems. Git is an excellent version control tool and is widely used for both developers and also infrastructure configuration. This post goes into how to put the VMware NSX configuration into version control using Git.

Not all infrastructure components (server systems, network devices, etc) have a proper audit log on what happens in the configuration and who is doing what exactly. This is where version control can lend a helping hand … Read more

Doing Dual ISP Load Balancing with Ubiquiti EdgeRouter

April 11, 2018 / Martijn / 17 Comments

Ever since I moved to a new house, I’ve been stuck to a pretty bad ISP. With no fiber, a few kilometers away from the DSL termination pop (so a max of 10Mbit on ADSL), it just leaves cable. Speeds aren’t terrible, I get a 400Mbit line for E 60,- p/m. Latency spikes and jitter are horrible, but that can be expected on a cable network. Especially fun when doing internet calls. 😉

All in all, I haven’t been enjoying my internet connection for a while and I wanted to do something about it.

Dual Connection

After dismissing the thought … Read more

VMware NSX & OTRS – Automating Security with Help Desk Systems

March 23, 2018 / Martijn / 0 Comments

Over the last couple of months, Sander, Anne Jan and I have been working on a security whitepaper that lays out a practical implementation of zero trust while interfacing with a helpdesk system. In this case, OTRS.

It’s all about how engineers can get access to servers to perform maintenance, once your environment is properly micro-segmented. This whitepaper talks about the challenges you have when you’re micro-segmented and how you can resolve these challenges. Using OTRS as an example, this document lays out how to configure a help desk system like OTRS to interface with NSX to gain network … Read more

Deploying VeloCloud on VMware vSphere

March 8, 2018 / Martijn / 9 Comments

Hopefully you’ve heard the good news that VMware has acquired VeloCloud, including SD-WAN into the software-defined portfolio. This is especially exciting to me, as I get to branch out a little more into the WAN space, being in the Networking & Security BU. For me, it also means NEW TOYS! 🙂

VeloCloud primarily runs on hardware in a few flavors (no software without hardware), but they also have a VM form factor (which I’m sure will get extra attention in the future). I managed to get a hold of an OVA to run in my lab. While you … Read more
