Worth Reading: Signposts on the roadmap to 10TB/sec

The world of Ethernet switching and routing used to be more predictable than just about any other part of the datacenter, but for the past decade the old adage – ten times the bandwidth for three times the cost – has not held. While 100 Gb/sec Ethernet was launched in 2010 and saw a fair amount of uptake amongst telecom suppliers for their backbones, the hyperscalers decided, quite correctly, that 100 Gb/sec Ethernet was too expensive and opted for 40 Gb/sec instead. —Timothy Prickett Morgan @ The Next Platform

What does the future hold for the Internet?

This is the fundamental question that we are posing through the report just launched today, our 2017 Global Internet Report: Paths to Our Digital Future.

The report is a window into the diverse views and perspectives of a global community that cares deeply about how the Internet will evolve and impact humanity over the next 5-7 years. We couldn’t know what we would find when we embarked on the journey to map what stakeholders believe could shape the future of the Internet, nor can we truly know what will happen to the Internet, but we do now have a sense of what we need to think about today to help shape the Internet of tomorrow. The report reflects the views and aspirations of our community as well as some of the most pressing challenges facing the future of this great innovation.

What have we learned? We’ve learned that our community remains confident that the core Internet values that gave rise to the Internet remain valid. We also heard very strong worries that the user-centric model of the Internet is under extraordinary pressure from governments, from technology giants, and even from the technology itself.  There is a sense that there Continue reading

What Kind of Design?

In this short video I work through two kinds of design, or two different ways of designing a network. Which kind of designer are you? Do you see one as better than the other? Which would you prefer to do, are you right now?

Aruba rolls out security fabric designed for IoT and the digital era

Aruba, a Hewlett Packard Enterprise Company, is best known for its outstanding business-grade Wi-Fi products. What’s less well known about Aruba is that it has always had excellent security products. In fact, I’ve often described the company as a security vendor dressed up as a Wi-Fi vendor, as Aruba and security have gone hand in hand like the New England Patriots and winning. However, Aruba’s security positioning has always been tactical rather than strategic because its products were used for specific purposes, such as end point protection or wireless security. That shifted this week at APAC Atmosphere in Macau when the company introduced its 360 Security Fabric, which enables it to provide end-to-end security to address the needs of a world that is becoming increasingly digitized. To read this article in full or to leave a comment, please click here

Evolution of data structures in Yandex.Metrica

Yandex.Metrica is the world's second largest web analytics system. Metrica takes in a stream of data representing events that took place on sites or on apps. Our task is to process this data and present it in an analyzable form.


Processing the data in itself is not a problem. The real difficulty lies in trying to determine what form the processed results should be saved in so that they are easy to work with. During the development process, we had to completely change our approach to data storage organization several times. We started with MyISAM tables, then used LSM-trees and eventually came up with column-oriented database, ClickHouse. In this article I'll explain what led us to settle on this last option.

Yandex.Metrica was launched in 2008 and has now been running for more than nine years. Every time we changed our approach to data storage in the past it was because a particular solution proved inefficient: either there was insufficient performance reserve, or the solution was unreliable, or it used too many computational resources, or it just did not allow us to implement what we needed to.

The old Yandex.Metrica for websites has more than 40 "fixed" Continue reading

W3C DRM appeal fails, votes kept secret

Earlier this summer, the World Wide Web Consortium (W3C) — the organization responsible for defining the standards that make up the Web — decided to embrace DRM (aka "EME") as a web standard. I wasn’t happy about this. I don’t know many who were.Shortly after that, the W3C agreed to talk with me about the issue. During that discussion, I encouraged the W3C to increase their level of transparency going forward — and if there is an appeal of their DRM decision, to make that process completely open and visible to the public (including how individual members of the W3C vote on the issue).To read this article in full or to leave a comment, please click here

Worth Reading: Why you should have a CAA DNS record

This Friday, all certificate authorities will have to honor a Domain Name System (DNS) record that allows HTTPS website owners to restrict who can issue SSL certificates for their domain names. It’s a long-needed defense against the issuance of fraudulent certificates, a security risk that domain owners had few protections for until now. The Problem: There are tens of certificate authorities (CAs) trusted in browsers and operating systems and any one of them can theoretically issue a valid SSL certificate for any website on the internet. Furthermore, many of these certificate authorities have subordinate CAs and resellers that are operated by separate organizations and which can also issue SSL certificates to end users. —Lucian Constantin @ The New Stack
