Announcing the VMware NSX vExpert Program
The VMware NSX team is excited to announce the new NSX vExperts program. If you’re not familiar with vExperts, the program is designed to recognize individuals who are passionate about sharing their knowledge on VMware technologies with the broader community. While the vExpert program has been around for over 10 years, this is the first year we’re introducing the NSX vExpert subprogram and badge.
What is an NSX vExpert?
Individuals awarded NSX vExpert status are the crème of the crop when it comes to their knowledge in NSX use cases like micro-segmentation, network automation, multi-cloud networking, service mesh and modern apps. They’re advocates of VMware NSX and love “giving back” to the community by sharing their knowledge with their peers— whether it be through blogging or public speaking at events like VMworld and VMUG.
Benefits of the NSX vExpert Program
Becoming an NSX vExpert is not without its perks. In addition to bragging rights and the cool badge, VMware will provide great opportunities to give you the recognition you deserve.
Here’s what vExperts gain:
- Amplification of any articles you write
- Exposure at VMware physical and virtual events
- Opportunities to interface and provide feedback to the NSX product team
- Invite Continue reading
Minister Bains, Let’s Rethink Canada’s Spectrum Auction
Yesterday’s announcement by the Government of Canada to drive down cell phone prices will only end up costing Canada in the long run.
In a press conference held yesterday, Minister Navdeep Bains of Innovation Science and Economic Development Canada (ISED) laid out a plan that will not only allow the government to evoke further regulation to boost competition but allow it to sell off spectrum to the highest bidder.
It is a case of short-term gain that will lead to long-term pain.
It could have been an opportunity for ISED to bring many Canadians – particularly those living in rural and remote areas – closer to the government’s goal of universal broadband for all by 2030. Unfortunately, we believe that the auction rules announced yesterday by Minister Bains for this spectrum band are a step backward for innovative approaches to bring affordable access to the regions of Canada that most need it.
Currently, Canadians pay some of the highest prices in the world to come online and much of the country still does not have fiber needed for broadband.
There are solutions to affordable access in Canada. One of which is community networks.
The Internet Society has long championed community Continue reading
International Women’s Day 2020: Building a Modern Security Team
When we started at Cloudflare in the summer of 2018, we joined a small security team intent on helping it grow quickly. Cloudflare was already a successful “unicorn” startup and its profile was changing fast, providing cyber security protection for millions of Internet-facing properties and moving towards becoming a public company. We were excited to help build the team that would ensure the security of Cloudflare’s systems and the sensitive customer data that flows through them.
Competing for security talent in the tech industry - where every company is investing heavily on security - isn't easy. But, in 18 months, we have grown our team 400% from under 10 people to almost 50 (and still hiring). We are proud that 40% of our team are women and 25% are from an under-represented minority. We believe from experience, and the research shows, that more diverse teams drive better business results and can be a better place to work.
In honor of International Women’s Day this Sunday, we wanted to share some of our lessons learned on how to build a diverse team and inclusive culture on a modern security team.

My Cisco Certified DevNet Professional Journey, Part 2 by Nick Russo
On 27 February 2020, I took and passed the Automating Cisco Enterprise Solutions (ENAUTO) exam on my first attempt. This was the last exam I took that day, having taken DEVASC and DEVCOR in earlier. This exam was a bit different for a few reasons, which I’ll discuss shortly. Passing both DEVCOR and ENAUTO has earned me the Cisco Certified DevNet Professional certification. Like the other DevNet exams, it was fair and reasonably well-written.
I’ve been working with Cisco products for more than 10 years and earning Cisco certifications for about 8 years, and this was my first specialist exam. You can learn more about the ENAUTO exam here. About 40% of the exam is based on general programming principles and network automation techniques, most of which overlap nicely with DEVASC and DEVCOR. The remaining 60% is divided evenly between Cisco’s biggest three enterprise solutions: DNA Center, SD-WAN, and Meraki at 20% each.
Before attempting this exam, you should already have a DevNet Associate certification (not required) or comparable knowledge, plus at least 3 years of network automation experience. Those skills alone cover probably 30% of the blueprint. If you already passed the DEVCOR exam (or have comparable Continue reading

The History of the URL
This issue was occuring now because the ARPANET was on the verge of switching from its original NCP protocol, to the TCP/IP protocol which powers what we now call the Internet. With that switch suddenly there would be a multitude of interconnected networks (an ‘Inter... net’) requiring a more ‘hierarchical’ domain system where ARPANET could resolve its own domains while the other networks resolved theirs.
Other networks at the time had great names like “COMSAT”, “CHAOSNET”, “UCLNET” and “INTELPOSTNET” and were maintained by groups of universities and companies all around the US who wanted to be able to communicate, and could afford to lease 56k lines from the phone company and buy the requisite PDP-11s to handle routing.
In the original ARPANET design, a central Network Information Center Continue reading
Best Computer for Engineering Students
Engineering students need a computer that is portable, has good CPU speed, lots of memory, great graphics, and is affordable, which means that the laptops useful for most students simply won’t be the best computer for engineering students. Ironically, the laptops that make the best computers for students in engineering are gaming computers.
Why Gaming Computers are the Best Computers for Engineering Students
The reason why gaming laptops tend to be the best computers for engineering students is because the features that make these laptops good for gaming are also the same features that engineering students need, including:
- A fast CPU speed
- Plenty of hard drive memory
- At least 8GB of RAM
- Wi-Fi and Bluetooth connectivity
- Excellent graphics
- Reasonable cost
While good gaming computers aren’t cheap, unless someone is a real hardcore gamer, gaming computers can be acquired for between $1,000 and $2,000, which is cheaper and much more portable than a workstation for engineering students. In addition, while great for completing engineering tasks, gaming computers will also allow engineering students to play games, as well as do all the things that regular laptops do.
This allows engineering students to save and share their work, as well as use the Continue reading
Cloud Networking Transformation Ahead
Networking is undergoing a metamorphosis. Today’s operations are challenged to cope with the DevOps, NetOps, SecOps and CloudOps models that need consistent operations control. Why should enterprises care? How do you cope with decades of legacy and is change possible? Arista believes that the networking world is at the cusp of a transformation, significantly facilitated by the agile, dynamic and economic network models of the public cloud providers. They have proven the elegance of simple yet scalable designs that transform siloed networks for the data center, core, campus or branch PINs (Places in the Network) into east west PICs(Places in the Cloud). This new paradigm is a far cry from the traditional siloed network architectures that required applications to be assigned to specific servers or storage, causing fixed-function rigidity. Agility and high availability are pivotal foundations to building the new PICs.

TL&DR: It’s 2020, and VXLAN with EVPN is all the rage. Thank you, you can stop reading.
On a more serious note, I got this questions from an Johannes Spanier after he read my do we need complex data center switches for NSX underlay blog post:
Would you agree that for smaller NSX designs (~100 hypervisors) a much simpler Layer2 based access-distribution design with MLAGs is feasible? One would have two distribution switches and redundant access switches MLAGed together.
I would still prefer VXLAN for a number of reasons:
