Advanced Solutions Customer Story Part 1: Why NSX-T?

 

Customer Overview

Advanced Solutions, a DXC Technology company, was formed in 2004 and employs about 500 staff to support the government of the Canadian province of British Columbia and other public sector customers with IT and business process solutions. For government agencies and services to continue operating efficiently and effectively, it is essential that the IT resources that they require are provided quickly and accurately.

Key Pain Points

All IT organizations are acutely familiar with the wide range of pain points and obstacles that can stand in the way of delivering resources to empower their businesses to move with speed and agility. One of the most common hindrances to IT, and therefore business agility is painfully slow provisioning processes, which can take weeks just to provision an application. The most common bottleneck within these processes is provisioning networking and security services. This is a key pain point for Advanced Solutions, but one that VMware is helping them solve with the VMware NSX Data Center network virtualization platform.

Dan Deane, Solutions Lead at Advanced Solutions says, “The key IT pain points that VMware solutions are helping us solve are around networking and provisioning.”

Helping To Build Cloudflare, Part 3: Audacity, Diversity and Change

This is part 3 of a six part series based on a talk I gave in Trento, Italy. To start from the beginning go here.

After Cloudbleed, lots of things changed. We started to move away from memory-unsafe languages like C and C++ (there’s a lot more Go and Rust now). And every SIGABRT or crash on any machine results in an email to me and a message to the team responsible. And I don’t let the team leave those problems to fester.

Making 1.1.1.1

So Cloudbleed was a terrible time. Let’s talk about a great time. The launch of our public DNS resolver 1.1.1.1. That launch is a story of an important Cloudflare quality: audacity. Google had launched 8.8.8.8 years ago and had taken the market for a public DNS resolver by storm. Their address is easy to remember, their service is very fast.‌‌

But we thought we could do better. We thought we could be faster, and we thought we could be more memorable. Matthew asked us to get the address 1.1.1.1 and launch a secure, privacy-preserving, public DNS resolver in a couple of months. Continue reading

Stuff The Internet Says On Scalability For February 1st, 2019

My experience is that more than half of researchers are not even trying to produce something useful. They are trying to publish, to get jobs and promotions, to secure grants and so forth, but advancing science is a secondary concern.

Community Network Champions Take a Rural Dip in India

By Digital Empowerment Foundation

In the last 25 years, half the world has been connected to the Internet and the almost infinite opportunities it has to offer. Most of these, among the 3.5 billion connected individuals of the world, are people who are largely economically empowered, literate, and reside in urban or accessible areas. However, there is also half the world that is yet to get online and access what the Internet has to offer them.

The biggest barrier to widespread connectivity is the high cost of infrastructure. With many telecom companies unwilling or unable to build infrastructure in far flung and rural areas, large swathes of the world have remained in media darkness. Evidently, most of those who are excluded from digital ecosystems are people who are largely at the bottom of the pyramid and reside in rural or inaccessible areas. They are people who have not been connected by the mainstream Internet Service Providers (ISP) – and who may have to wait a long time to be connected.

So who will take the responsibility of connecting them?

It has to be the community themselves.

Over the years, community network providers have proved to be great enablers for Continue reading

Helping To Build Cloudflare, Part 1: How I came to work here

This is the text I prepared for a talk at Speck&Tech in Trento, Italy. I thought it might make a good blog post. Because it is 6,000 words I've split it into six separate posts.

Here's part 1:

I’ve worked at Cloudflare for more than seven years. Cloudflare itself is more than eight years old. So, I’ve been there since it was a very small company. About twenty people in fact. All of those people (except one, me) worked from an office in San Francisco. I was the lone member of the London office.

Today there are 900 people working at Cloudflare spread across offices in San Francisco, Austin, Champaign IL, New York, London, Munich, Singapore and Beijing. In London, my “one-person office” (which was my spare bedroom) is now almost 200 people and in a month, we’ll move into new space opposite Big Ben.

The original Cloudflare London "office"

The numbers tell a story about enormous growth. But it’s growth that’s been very carefully managed. We could have grown much faster (in terms of people); we’ve certainly raised enough money to do so.

I ended up at Cloudflare because I gave a really good talk at a conference. Well, Continue reading

National pen test execution standard would improve network security

As the number of cyber attacks increases, the demand for penetration tests – to determine the strength of a company’s defense – is also going up. People are worried about their companies’ networks and computer systems being hacked and data being stolen. Plus, many regulatory standards such PCI and HITRUST require these tests to be performed on at least an annual basis.The demand for these tests is only going to increase as attackers get more sophisticated. And it’s essential these tests catch all possible vulnerabilities.[ Also read: What to consider when deploying a next-generation firewall | Get regularly scheduled insights: Sign up for Network World newsletters ] Benefits and gaps of penetration tests Penetration tests involve live tests of computer networks, systems, or web applications to find potential vulnerabilities. The tester actually attempts to exploit the vulnerabilities and documents the details of the results to their client. They document how severe the vulnerabilities are and recommend the steps that should be taken in order to resolve them.To read this article in full, please click here

Technology Short Take 110

Welcome to Technology Short Take #110! Here’s a look at a few of the articles and posts that have caught my attention over the last few weeks. I hope something I’ve included here is useful for you also!

Networking

  • Via Kirk Byers (who is himself a fantastic resource), I read a couple of articles on network automation that I think readers may find helpful. First up is a treatise from Mircea Ulinic on whether network automation is needed. Next is an older article from Patrick Ogenstad that provides an introduction to ZTP (Zero Touch Provisioning).
  • The folks over at Cilium took a look at a recent CNI benchmark comparison and unpacked it a bit. There’s some good information in their article.
  • I first ran into Forward Networks a few years ago at Fall ONUG in New York. At the time, I was recommending that they explore integration with NSX. Fast-forward to this year, and the company announces support for NSX and (more recently) support for Cisco ACI. The recent announcement of their GraphQL-based Network Query Engine (NQE)—more information is available in this blog post—is also pretty interesting to me.

Worth Reading: Should I Write a Book?

Erik Dietrich (of the Expert Beginner fame) published another great blog post explaining when and why you should write a book. For the attention-challenged here’s my CliffNotes version:

  • Realize you have no idea what you’re doing (see also: Dunning-Kruger effect)
  • Figure out why you’d want to spend a significant amount of your time on a major project like book writing;
  • It will take longer (and will be more expensive) than you expect even when considering Hofstadter’s law.
