For Google Networks, Predictable Latency Trumps Everything

If you want to build infrastructure that scales larger than a single image of a server and an operating system, you have no choice but to network together multiple machines. And so, the network becomes a kind of hyper backplane between compute elements and, in many cases, also a kind of virtual peripheral bus for things like disk and flash storage. From the outside, a warehouse-scale computer, as Google has been calling them for nearly a decade, is meant to look and behave like one machine even if it most certainly is not.

It is hard to quantify how …

A Sublime Text Keymap for Bracketeer

I’ve made no secret of the fact that I’m a fan of Sublime Text (ST). I’ve evaluated other editors, like Atom, but still find that ST offers the right blend of performance, functionality, customizability, and cross-platform support. One nice thing about ST (other editors have this too) is the ability to extend it via packages. Bracketeer is one of many packages that can be used to customize ST’s behavior; in this post, I’d like to share a keymap I’m using with Bracketeer that I’ve found very helpful.

Bracketeer is a package that modifies ST’s default bracketing behavior. I first started using Bracketeer to help with writing Markdown documents, as it makes adding brackets (or parentheses) around existing text easier (it automatically advances the insertion point after the closing bracket). After using Bracketeer for a little while, I realized I could extend the keymap for Bracketeer to have it also help me with “wrapping” text in backticks and a few other characters. I did this by adding this line to the default keymap:

{
  "keys": [ "`" ],
  "command": "bracketeer",
  "args": {
    "braces": "``",
    "pressed": "`"
  }
}

With this line in the keymap, I could select some text, press Continue reading

Blockchain poised to disrupt traditional retail operations

The demise of retail grocery stores might be just around the corner.The founders of Russian grocery delivery company Instamart claim to have signed non-binding memoranda with consumer goods giant Unilever, major Dutch dairy co-op FrieslandCampina, and U.S. food products manufacturer Mars, among others. INS’s objective is to build a blockchain-based food-supply network to connect manufacturers with consumers — thus bypassing retailers and wholesalers altogether. Massive consumer price cuts are promised.Also on Network World: Blockchain: You’ve got questions; we’ve got answers “INS is a decentralized ecosystem that enables consumers to buy directly from grocery manufacturers, bypassing retailers and wholesalers, at prices up to 30 percent lower than in supermarkets,” the company says in its press release. The firm will be releasing a token sale at the end of this month — the first stage of its launch planned for Q4 2018.To read this article in full or to leave a comment, please click here

VMware jumps into SD-WAN with VeloCloud purchase

VMware today announced plans to acquire VeloCloud, one of the leading companies in the fast-growing software-defined Wide Area Network (SD-WAN) market.SD-WAN represents a new way to manage network connectivity to branch and remote offices using software-defined networking principles. Software-based SD-WAN offerings from companies like VeloCloud can aggregate multiple types of connections, including broadband, MPLS and cellular, to create more reliable connections that are often less expensive than a pure MPLS use. Research firm IDC predicts SD-WAN will be a more than $1 billion market this year, and grow at 69% to more than $8 billion by 2021.To read this article in full or to leave a comment, please click here

Reaction: Enabling Privacy is not Harmful

The argument for end-to-end encryption is apparently heating up with the work moving forward on TLSv1.3 currently in progress in the IETF. The naysayers, however, are also out in force, arguing that end-to-end encryption is a net negative. What is the line of argument? According to a recent article in CircleID, it seems to be something like this:

  • Governments have a right to asymmetrical encryption capabilities in order to maintain order. In other words, governments have the right to ensure that all private communication is ultimately readable by the government for any lawful purpose.
  • Standards bodies that enable end-to-end encryption that will prevent this absolute governmental good endanger society. The leaders of such standards bodies may, in fact, be prosecuted for their role in subverting government power.

The idea of end-to-end encryption is recast as a form of extremism, a radical idea that should not be supported by the network engineering community. Is end-to-end encryption really extremist? Is it really a threat to the social order?

Let me begin here: this is not just a technical issue. There are two opposing worldviews in play. Engineers don’t often study worldviews, or philosophy, so these questions tend to get buried in Continue reading

MINIX — The most popular OS in the world, thanks to Intel

Take a look at your desktop computer. What operating system is it currently running? Now take a look in your data center — at all of your servers. What operating system are they running? Linux? Microsoft Windows? Mac OS X? You could be running any of those three — or one of countless others. But here’s the crazy part: That’s not the only operating system you’re running. If you have a modern Intel CPU (released in the last few years) with Intel’s Management Engine built in, you’ve got another complete operating system running that you might not have had any clue was in there: MINIX. To read this article in full or to leave a comment, please click here

IDG Contributor Network: Cisco Aironet Developer Platform: a stealth IoT opportunity for developers

In mid-October, Cisco announced the launch of its Aironet Developer Platform (ADP), a third-party development platform based on the Aironet 3800 series access points (AP). While there was no mention of IoT in the announcement, this is a stealth IoT opportunity. While Cisco’s Kinetic and Jasper IoT platforms reside in the cloud, ADP focuses on the edge within the enterprise. The ability to manage the “internal edge” and integrate with the Kinetic platform is significant. Throw in the DevNet developer community, a large existing base of Aironet APs, and suddenly Cisco customers are doing IoT.To read this article in full or to leave a comment, please click here

Intesa Sanpaolo Builds a Resilient Foundation for Banking With Docker Enterprise Edition

Intesa Sanpaolo is the largest bank in Italy and maintains a network of over 5,000 banking branches across Europe and North Africa. With nearly 19 million customers and €739 billion in assets, Intesa Sanpaolo is an integral part of the financial fabric and as such, Italian regulations require that they keep their business and applications online to serve their customers.

As a bank that can trace its roots back to the early 1800s, the majority of Intesa’s edge applications are still monolithic and hard to move between data centers, never mind migrate to the cloud. Diego Braga, Intesa IT Infrastructure Architect, looked to Docker Enterprise Edition (EE) at the recommendation of his Kiratech business partner Lorenzo Fontana to improve their application availability, portability and add cloud friendly application delivery. With Docker EE, Intesa was able to consolidate infrastructure by nearly 60%, thus saving significant money over their previous design, while also enabling higher application availability across regional data centers and preparing themselves for the cloud.

Docker Enterprise

Prior to the Docker EE implementation, not only were the applications monoliths, but Intesa maintained two separate data centers as mirrors of each other to achieve high availability. This design required excess, cold standby hardware capacity in Continue reading
