Keynote Hate – Celebrity Edition

We all know by now that I’m not a huge fan of keynotes. While I’ve pulled back in recent years from the all out snark during industry keynotes, it’s nice to see that friends like Justin Warren (@JPWarren) and Corey Quinn (@QuinnyPig) have stepped up their game. Instead, I try to pull nuggets of importance from a speech designed to rally investors instead of the users. However, there is one thing I really have to stand my ground against.

Celebrity Keynotes.

We’ve seen these a hundred times at dozens of events. After the cheers and adulation of the CEO giving a big speech and again after the technical stuff happens with the CTO or product teams, it’s time to talk about…nothing.

Celebrity keynotes break down into two distinct categories. The first is when your celebrity is actually well-spoken and can write a speech that enthralls the audience. This means they get the stage to talk about whatever they want, like their accomplishments in their career or the charity work their pushing this week. I don’t mind these as much because they feel like a real talk that I might want to attend. Generally the celebrity talking Continue reading

A Letter from Matthew Prince and Michelle Zatlyn

To our potential shareholders:

Cloudflare launched on September 27, 2010. Many great startups pivot over time. We have not. We had a plan and have been purposeful in executing it since our earliest days. While we are still in its early innings, that plan remains clear: we are helping to build a better Internet. Understanding the path we’ve taken to date will help you understand how we plan to operate going forward, and to determine whether Cloudflare is the right investment for you.

Cloudflare was formed to take advantage of a paradigm shift: the world was moving from on-premise hardware and software that you buy to services in the cloud that you rent. Paradigm shifts in technology always create significant opportunities, and we built Cloudflare to take advantage of the opportunities that arose as the world shifted to the cloud.

As we watched packaged software turn into SaaS applications, and physical servers migrate to instances in the public cloud, it was clear that it was only a matter of time before the same happened to network appliances. Firewalls, network optimizers, load balancers, and the myriad of other hardware appliances that Continue reading

How 6G will work: Terahertz-to-fiber conversion

Upcoming 6G wireless, superseding 5G and arriving possibly by 2030, is envisaged to function at hundreds of gigabits per second. Slowly, the technical advances needed are being made.A hole in the tech development thus far has been at the interface between terahertz spectrum and hard, optical transmission lines. How does one connect terahertz (THz), which is basically through-the-air spectrum found between microwave and infrared, to the transmission lines that will be needed for the longer-distance data sends? The curvature of the Earth, for one thing, limits line of sight, so hard-wiring is necessary for distances. Short distances, too, can be impeded by environmental obstructions: blocking by objects, even rain or fog, becomes more apparent the higher in spectrum one goes, as wavelengths get shorter.To read this article in full, please click here

An Introduction to Kustomize

kustomize is a tool designed to let users “customize raw, template-free YAML files for multiple purposes, leaving the original YAML untouched and usable as is” (wording taken directly from the kustomize GitHub repository). Users can run kustomize directly, or—starting with Kubernetes 1.14—use kubectl -k to access the functionality (although the standalone binary is newer than the functionality built into kubectl as of the Kubernetes 1.15 release). In this post, I’d like to provide an introduction to kustomize.

In its simplest form/usage, kustomize is simply a set of resources (these would be YAML files that define Kubernetes objects like Deployments, Services, etc.) plus a set of instructions on the changes to be made to these resources. Similar to the way make leverages a file named Makefile to define its function or the way Docker uses a Dockerfile to build a container, kustomize uses a file named kustomization.yaml to store the instructions on the changes the user wants made to a set of resources.

Here’s a simple kustomization.yaml file:

resources:
- deployment.yaml
- service.yaml
namePrefix: dev-
namespace: development
commonLabels:
  environment: development

Video: Beyond Two Nodes

In the introductory videos of How Networks Really Work webinar I described the mandatory elements of any networking solution and additional challenges you have to solve when you can’t pull a cable between the adjacent nodes.

It’s time for the next bit of complexity: what if we have more than two nodes connected to the same network segment? Welcome to the world of multi-access networks and data link control.

You need free ipSpace.net subscription to watch the videos in Overview of Networking Challenges section, or a paid ipSpace.net subscriptions to watch the rest of the webinar.

Declarative recursive computation on an RDBMS

Declarative recursive computation on an RDBMS… or, why you should use a database for distributed machine learing Jankov et al., VLDB’19

If you think about a system like Procella that’s combining transactional and analytic workloads on top of a cloud-native architecture, extensions to SQL for streaming, dataflow based materialized views (see e.g. Naiad, Noria, Multiverses, and also check out what Materialize are doing here), the ability to use SQL interfaces to query over semi-structured and unstructured data, and so on, then a picture begins to emerge of a unifying large-scale data platform with a SQL query engine on top that addresses all of the data needs of an organisation in a one-stop shop. Except there’s one glaring omission from that list: handling all of the machine learning use cases.

Machine learning inside a relational database has been done before, most notably in the form of MADlib, which was integrated into Greenplum during my time at Pivotal. The Apache MADLib project is still going strong, and the recent (July 2019) 1.16 release even includes some support for deep learning.

To make that vision of a one-stop shop for all of an organisation’s data Continue reading

ClearOS Gateway on GNS3

In a previous tutorial we have successfully installed ClearOS on QEMU VM in a gateway mode. At the end of the tutorial we have installed several apps from ClearOS marketplace. These apps enhance gateway functionality, however  we have not tested  them yet. Therefore, this tutorial goes further and we are going to test some services offered by ClearOS apps. In order to do it, we will connect ClearOS QEMU appliance into a GNS3 topology.

Our ClearOS QEMU instance is configured with two guest network cards (Picture 1). The first guest interface ens3 has assigned the LAN role and it is configured with the IP address 192.168.1.254/24. This is the IP address a web server is listening on, the port 81. The entire ClearOS management will be done via web browser using the url https://192.168.1.254:81.

Picture 1 - Network Interfaces Configuration During ClearOS Installation

The second guest interface ens4 has assigned External role and its IP address is assigned from DHCP server. DHCP server is running on SOHO router with the IP address 172.17.100.1/16 (Picture 2).

Picture 2 - Network Topology

GNS3 itself connects the second guest interface ens4 of ClearOS gateway Continue reading

BrandPost: Top 3 Misconceptions About SD-WAN

There’s little question that software-defined wide-area networks (SD-WANs) have taken off, as companies look for increased network resiliency and control. But there’s still significant confusion about SD-WAN, including some benefits that are more myth than reality.In this post, we’ll explore three common misconceptions that surround SD-WAN, starting with what is probably the most important one.Misconception #1: SD-WAN will replace services such as MPLS SD-WAN doesn’t necessary replace any existing network service, be it MPLS, broadband Internet, or anything else. In fact, it requires some kind of network service to work at all.To read this article in full, please click here

IBM Injects Cloud Innovation Into Its z15 Mainframe
