Forget the CES hype, IoT is all about industry

This week the gadget industry descends up on Las Vegas for the annual Consumer Electronics Show (CES). And as in the previous few years, 2018’s CES is chock-full of smart devices of every stripe. Some seem very cool, others unutterably silly, and a tiny percentage might be actually useful. A few will find market success, and many more will never actually hit the market at all.In addition to all the new product previews, this year’s CES is full of summits, seminars, presentations and other sessions devoted to helping consumer products companies make, sell, deploy and monetize everything from smart cars and smart homes to smart cities.To read this article in full, please click here

Docker for Mac with Kubernetes

Docker Community Edition

You heard about it at DockerCon Europe and now it is here: we are proud to announce that Docker for Mac with beta Kubernetes support is now publicly available as part of the Edge release channel. We hope you are as excited as we are!

With this release you can now run a single node Kubernetes cluster right on your Mac and use both kubectl commands and docker commands to control your containers.

First, a few things to keep in mind:

  • Docker for Mac required
    Kubernetes features are only accessible on macOS for now; Docker for Windows and Docker Enterprise Edition betas will follow at a later date. If you need to install a new copy of Docker for Mac you can download it from the Docker Store.
  • Edge channel required
    Kubernetes support is still considered experimental with this release, so to enable the download and use of Kubernetes components you must be on the Edge channel. The Docker for Mac version should be 17.12.0-ce-mac45 or later after updating.
  • Already using other Kubernetes tools?
    If you are already running a version of kubectl pointed at another environment, for example minikube, you will want to follow the activation Continue reading

Hyperconverged secondary storage market heats up

There’s no question that the hyperconverged infrastructure (HCI) has had a huge impact on simplifying technology deployments. Nutantix solutions, Cisco HyperFlex and HPE Simplivity have been widely adopted and have changed the face of the data center.HCI was initially considered niche to simplify the deployment of virtual desktop infrastructure (VDI), but it has seen increased adoption for other workloads. One use case for HCI that has flown under the radar is secondary storage. Late last year, I profiled Cohesity, the vendor that has been leading the emerging hyperconverged secondary storage market.To read this article in full, please click here

Accelerate Network Automation with Aggregate Resources

One of the major networking features in Red Hat Ansible Engine 2.4 was the addition of aggregate resources to the networking modules. The Ansible networking team recently talked about this at the Ask an Expert webinar in November.

What are Aggregate Resources?

Simply put, aggregate resources are a better way to iterate (or loop) without the need to execute each task one by one. That is, you can now “aggregate” a collection as a single task instead of a collection of discrete loops.

Loop Method

Worth Reading: Why the Full Time Job is Still Important

The new “rules” of the workplace are being defined as computers are frantically being programmed to take the lead in the workplace, when it comes to judgment and intuition. We humans need to be the idea generators, the motivators, the negotiators, and the trouble-shooters to fix computer errors, if we want to govern our emerging digital environments. In short, we need to get closer to our firms, be more tightly integrated and intimate with work performance than ever before… which means the role and tenure of the much-derided middle-manager in the Dilbert Cartoons could be taking on a whole new potential twist – and a whole new (potential) level of relevance. —Phil Fersht @ The Enterprise Irregulars

IDG Contributor Network: How network verification differs from monitoring, and what it’s good for

In a previous post I discussed network verification, a new area of technology that applies what is known as formal verification – mathematical analysis of a complex system to determine rigorously if it meets the end-to-end goal – to network infrastructure.But what is such verification good for and how is it different from today’s common practice, whereby nearly every organization monitors its network, typically by sampling ongoing flows, events or logs. Isn’t that enough to catch problems as the organization deploys changes?To read this article in full, please click here

Section 10 Routing Loops

A (long) time ago, a reader asked me about RFC4456, section 10, which says:

Care should be taken to make sure that none of the BGP path attributes defined above can be modified through configuration when exchanging internal routing information between RRs and Clients and Non-Clients. Their modification could potentially result in routing loops. In addition, when a RR reflects a route, it SHOULD NOT modify the following path attributes: NEXT_HOP, AS_PATH, LOCAL_PREF, and MED. Their modification could potentially result in routing loops.

On first reading, this seems a little strange—how could modifying the next hop, Local Preference, or MED at a route reflector cause a routing loop? While contrived, the following network illustrates the principle.

Note the best path, from an IGP perspective, from C to E is through B, and the best path, from an IGP perspective, from B to D is through C. In this case, a route is advertised over eBGP from F towards E and D. These two eBGP speakers, in turn, advertise the route to their iBGP neighbors, B and C. Both B and C are route reflectors, so they both reflect the route on to A, which advertises the route to some other Continue reading

How Technology is Changing Music to fit Inside Streaming’s New Box

 

Technology shapes and forms. A Roman war chariot could still ride to battle on a modern road. Songs are typically about 3 minutes long because a 78rpm record held about three minutes of sound per side. So it shouldn't be a surprise streaming—a new technology for distributing music—pounds songs, business models, and production methods into new shapes fitting a new medium.

How would artists respond to near zero digital production costs, zero marginal distribution costs, and streaming's pay per play business model? Uniquely, as described in great detail in the podcast WS More or Less: Why Albums are Getting Longer.

Michael Jackson's Thriller album had nine tracks and runs at just over 42 minutes. Chris Brown released Heartbreak on a Full Moon, an album with 45 tracks and runs well over 2 hours. Albums are getting longer.

Why? You get what you measure.

1500 plays or streams of a track from a single album counts as a record sale. So the longer the album the fewer people have to listen to the whole thing to increase record sales. Record sales are how chart rankings are determined. Doing better in the charts gets you more exposure, which Continue reading

14,000 Incidents: a 2017 Routing Security Year in Review

How was the state of the Internet’s routing system in 2017? Let’s take a look back using data from BGPStream. Some highlights:

  • 13,935 total incidents (either outages or attacks like route leaks and hijacks)
  • Over 10% of all Autonomous Systems on the Internet were affected
  • 3,106 Autonomous Systems were a victim of at least one routing incident
  • 1,546 networks caused at least one incident

An ‘incident’ is a suspicious change in the state of the routing system that can be attributed to an outage or a routing attack, like a route leak or hijack (either intentional or due to a configuration mistake).[i] Let’s look at just a few examples of incidents picked up by the media.

March 2017. SECW Telecom in Brazil hijacked prefixes of Cloudflare, Google, and BancoBrazil causing some outage for these services in the region.

April 2017. Large chunks of network traffic belonging to MasterCard, Visa, and more than two dozen other financial services companies were briefly routed through a Russian telecom. For several minutes, Rostelecom was originating 50 prefixes for numerous other Autonomous Systems, hijacking their traffic.

August 2017. Google accidentally leaked BGP prefixes it learned from peering relationships, essentially becoming a transit provider instead Continue reading

Adminstravia 010918

I’ve reorganized the menu on the left just a little, combining some items under “reading,” and adding a new item called “topics.” Under this new item, you’ll find collections of articles on specific topics from other sources, starting with the ‘net neutrality page and the meltdown and spectre post reformatted as a page, with some new additions. I’m always trying to find new ways to organize the information here, making it easier to find things; hopefully this is a useful change.
