On the ‘net: Net Neutrality Explained


Net Neutrality seems like a simple, easy to understand concept—but it seems the deeper you dig into the concept, this appearance of simplicity is actually just a light coat of surfacing on a very complex set of problems. The best place to begin is with the basic premise of net neutrality: providers who are transporting data should treat every packet the same, regardless of the source, the destination, or the service. —Tech Target

IDG Contributor Network: Ayyeka Sigfox IoT sensors monitor sewage deep underground San Francisco

San Francisco depends on a thousand miles of sewers to keep the city running smoothly.The city collects up to 500 million gallons of waste water in a day when it rains. This waste water is transported to one of three treatment plants where pollutants are removed before being discharged into San Francisco Bay.Processing sewage is challenging in San Francisco because the city has the Pacific Ocean on three sides of it. During storm conditions, groundwater and storm water can overload the sewage system. Physical, chemical and biological processes remove contaminants from the waste water. This produces environmentally safe water and sewage sludge as a byproduct.To read this article in full or to leave a comment, please click here

Baidu Targets Deep Learning Scalability Challenges

When it comes to solving deep learning cluster and software stack problems at scale, few companies are riding the bleeding edge like Chinese search giant, Baidu. As we have detailed in the past, the company’s Silicon Valley AI Lab (SVAIL) has some unique hardware and framework implementations that put AI to the test at scale. As it turns out, scalability of the models they specialize in (beginning with speech recognition) is turning out to be one of the great challenges ahead on all fronts—hardware, compiler/runtime, and framework alike.

As we have described across multiple use cases, at Baidu and elsewhere …

BrandPost: DevOps at Wells Fargo

Portions of this post were originally posted on the Puppet blog, and are republished here with Puppet's permission.As one of the world's largest banks, Wells Fargo competes by innovating its IT. At the heart of its innovation is the ability to continually launch, maintain and update software. You can get some sense of the scale when you hear that the Wells Fargo IT organization manages an infrastructure that supports 1 billion transactions per day.With more than 120,000 servers, 55,000 network devices, more than 2,300 applications in production, and more than 6,000 ways to deliver change to a server, Wells Fargo IT needs a consistent way to manage infrastructure, and a consistent way to plan each application's architecture.To read this article in full or to leave a comment, please click here

Worth Reading: Overcoming data center cabling challenges

Now, many users have started employing high-density 40GbE switch line cards to break out as part of 10GbE applications. For example, a high-density 10GbE SFP+ line card has 48x10GbE ports, whereas a high-density 40GbE QSFP+ board may have 36x40GbE ports. As such, a 40GbE line card can be used to obtain 4×36 = 144x10GbE ports in the same cabling space and power-consumption conditions, thus reducing the cost and power consumption of the single-port 10GbE. —Data Center Journal

QUIC

A QUIC update on Google’s experimental transport describes some of the benefits of  the QUIC (Quick UDP Internet Connections) protocol that is now the default transport when Google's Chrome browser connects to Google services (gmail, search, etc.). Given the over 50% market share of the Chrome browser (NetMarketShare) and the popularity of Google services, it is important to be aware of the QUIC protocol and to start tracking its use of network resources.

An easy way to see if you have any QUIC traffic on your network is to use the standard sFlow instrumentation built into network switches. Configure the switches to send sFlow telemetry to an sFlow collector for visibility into network traffic.

For example, use Docker to run the sFlow-RT active-flows application to analyze the sFlow data stream:
docker run -p 6343:6343/udp -p 8008:8008 -d sflow/top-flows
Access the web interface at http://localhost:8008/ and enter the following Flow Specification to monitor QUICK flows: 
dns:ipsource,dns:ipdestination,quicpackettype
Note: Real-time domain name lookups describes how sFlow-RT incorporates DNS (Domain Name Service) requests in its real-time analytics pipeline so that traffic flows can be identified by domain name.

The resulting top flows table is shown in the screen capture above. Continue reading

Apple gives sneak peek of spaceship-like Apple Park that’s opening in April

Apple this week announced that its new 175-acre campus in Cupertino will be called Apple Park and is set to open in April. It will take six months to migrate 12,000 employees to the spaceship-like building, which Apple boasts runs entirely on renewable energy.Whereas Apple is generally cryptic about the locations of its facilities (the black hole that is Apple public relations, for example, recently failed to reply to our inquiry about its R&D spaces), the company is touting its new centerpiece for all things Mac and iOS. The facility, said to cost as much as $5 billion to construct, has previously been glimpsed mainly via drone fly-bys.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Software development genetics, part 1: DevOps, lean, agile

In a recent blog post, Recombinant communications: The new 'genetics' of enterprise communications, I drew parallels between the impacts of genetic engineering and how the application programming interface (API) economy and as-a-service industries are changing the enterprise communications market. A set of techniques that are gaining increasing numbers of adherents among software developers in other industries is similarly providing new “genetic” material that also promises revolutionary changes. The innovation framework DevOps, microservices and containers are the tools and constituents of this new “genetic” engineering in the software world.  To read this article in full or to leave a comment, please click here
