Envisioning a day in the future cloud-connected world

The very term "cloud" refers to any computing resource not in your current building. There is cloud storage, computing, and various applications ranging from the success of Salesforce online apps to the map you used on your phone (or watch) this morning.The Internet is now synonymous with the The Cloud. Let's dream about the cloud a little bit.Your JourneyYour body token was read by an RFID scanner as you walked in the door to the (train station, airport, building complex entrance) where it authorized you to go inside, noted you have $20 to spend on food in the (canteen, restaurant, company cafeteria), and that you can use the (company self-driving car, network terminals, network itself to Grade 51, doors to all red/green/black restrooms with unlimited toilet paper) and are permitted to exit any door.To read this article in full or to leave a comment, please click here

Spec showdown: HTC’s J Butterfly flies past its One M9

Unless you live in Japan, get ready to feel jealous: HTC on Thursday announced a new and impressive J Butterfly that is only available there. Here is how it compares to the One M9, currently the most advanced smartphone from HTC available globally.Both smartphones are powered by Qualcomm’s Snapdragon 810 processor and have 32GB of integrated storage, but a review of the specs shows a number of opportunities HTC missed with the One M9, which started shipping in March.ScreenThe One M9 has a 5-inch screen and the Butterfly’s screen measures 5.2 inches. But the newcomer has a 1440 x 2560 pixel resolution compared to 1080 x 1920 pixels on the One M9. That puts the Butterfly on par with competitors like Samsung’s Galaxy S6 and LG’s G4. To go along with all those pixels, the Butterfly also has a bigger battery. You can say what you like about whether the higher resolution is necessary, but One M9 is at a distinct disadvantage.To read this article in full or to leave a comment, please click here

Better than best effort — Rise of the IXP

In my last post I talked about how the incentive models on the Internet keep ISPs from managing peering and backbone capacity in a way that supports reliable communication in the face of ever growing volume of rich media content. If you haven't done so, please read that post before you read this one.

It's clear that using an ISP for business communication comes with the perils associated to the "noisy neighbor" ebb and flow of consumer related high volume data movement. Riding pipes that are intentionally run hot to keep costs down is a business model that works for ISP, but not for business users of the Internet. Even with business Internet service, customers may get a better grade of service within a portion of an ISP's networks, but not when their data needs to traverse another ISP which they are not a customer of. There is no consistent experience, for anyone.

However there is an evolving solution to avoid getting caught in the never ending battle between ISP and large consumer content. As the title of this blog gives away, the solution is called an Internet eXchange Point (IXP).

IXPs are where the different networks that make up Continue reading

BlackBerry CEO/Twitter latecomer on how he got @JohnChen handle: ‘Beats me…very lucky’

There are more John Chens on Twitter than a patient person can count, yet when Blackberry CEO John Chen started tweeting just a week ago he had somehow managed to secure the coveted and unique-among-Chens Twitter handle of @JohnChen.How?As anyone who has ever signed up for an email or social media account knows, you can never get your own name plain and simple unless you’re an earliest of early adopters or you have a highly uncommon name. You Browns, Smiths, Johnsons -- and Chens -- know this better than most.Twitter has been around for nine years now and if you enter the name John Chen into its people search you can scroll page after page of John Chens for as long as you’re willing to scroll. Their Twitter handles, however, are all @JohnChenPlusANumber or @JohnMiddleInitialChen or some other variation involving underscores or a nickname.To read this article in full or to leave a comment, please click here

For whatever reason, we seem to have moved into the “summer doldrums” a bit early this year. Emails seem to just not being answered for weeks — if ever — several friends have emailed me in the last week or two ago asking if it was just them, or if the IT industry was going crazy. All that said, though, there is still a lot going on in the world of IT.

Geoff Huston — if you don’t follow the rantings of Geoff, you really should — makes a point I wish I’d thought of first. The Internet of Things isn’t necessarily a security risk so much as it’s just a stupidity risk. He uses the example of millions of smaller home based devices being shipped with hard coded IP addresses that impact time and DNS servers to make the point that once things are deployed, they don’t tend to be touched. “If it ain’t broke, don’t fix it.” He calls it the Internet of Stupid Things.

Along those same lines, I saw an article this week about how Microsoft is threatening the end of the world (or some such) because they’re ending support for Windows 2003 server. The Continue reading

Nuage Announces Underlay/Overlay Event Management Platform

Nuage Networks Logo

During the ONUG event I met with Dimitri Stiliadis, the Co-Founder & Chief Technology Officer of Nuage Networks, who was excited to tell us about the latest product release, the Virtualized Services Assurance Platform (VSAP).

Virtualized Services Assurance Platform

The history of Nuage products has been fairly straightforward; they began with a virtualized networking solution targeted at data centers. More recently, Nuage Networks announced an expansion of that product into the branch office space. What was missing though, was a good way to monitor and manage the complex environment that was built, from underlay to overlay, from the WAN all the way to from virtual switch. When failures occur, they can be difficult to track down or, worse, you are flooded with alerts and left to figure out which ones are actually important, and which ones are the true root cause. To that end, Nuage Networks’ VSAP aims to provide visibility of the network and event correlation so that you can see what might be affected by a given network event.

VSAP is composed of two main components:

Route Monitor

The Nuage Route Monitor uses route protocols to peer with the production network in the data center, backbone, and anywhere else Continue reading

Wi-Fi Design and Capacity Planning Webinars, May 19th and 21st

Please consider attending webinars I'll be hosting on Wi-Fi design and capacity planning next week with Aruba Networks. I'll be talking about the key aspects to WLAN performance and the approach that I take to integrating coverage and capacity into a holistic design, as well as tools you can use to monitor WLAN performance after deployment to maintain a high-performing network and plan for growth.

These won't be traditional marketing webinars. If you're like me, you get invited to (and avoid) many webinars because they are too sales oriented and lack relevant engineering content. This isn't that. The goal of these webinars is to provide practical, real-world concepts and methods to help you design better Wi-Fi networks. Everyone deserves better Wi-Fi, right?

Build Your Development or Lab Environment with Ravello Systems

When preparing for my Simplifying Application Workload Migration workshop (coming in webinar format in autumn) I tried to find a solution that would allow me to recreate existing enterprise virtual network infrastructure in a cloud environment. Soon I stumbled upon Ravello Systems, remembered hearing about them on a CloudCast.net podcast, and got in touch with them to figure out whether they could help me solve that challenge.

It turned you might use Ravello Systems’ solution to implement disaster recovery, but I got way more excited about the possibility to use their solution for labs or testing. To learn more about that, listen to Episode 32 of Software Gone Wild.

To push electric cars, Seoul rolls out portable chargers with RFID

Seoul is trying to put one of the world’s highest concentrations of electric vehicles (EVs) on its roads with a project that would let drivers charge their vehicles in residential parking lots and other everyday locations.The city is planning to give out electric charger cables fitted with RFID readers that would allow drivers to recharge their batteries through standard power outlets at 100,000 locations—a huge increase from current numbers.Central to the project is a charger cable called the EV-Line, developed by Gyeonggi-based Power Cube. The cable has an RFID reader than can scan an RFID tag attached to power outlets in parking lots for apartments, offices and elsewhere. It also has a 3G wireless module.To read this article in full or to leave a comment, please click here

United launches bug bounty, but in-flight systems off limits

United Airlines is offering rewards to researchers for finding flaws in its websites but the company is excluding bugs related to in-flight systems, which the U.S. government says may be increasingly targeted by hackers.The bug bounty program rewards people with miles that can be used for the company’s Mileage Plus loyalty program as opposed to cash, which web giants such as Google, Facebook and Yahoo pay.Many companies have launched reward programs to attract independent researchers to investigate their software code and confidentially report flaws before hackers discover them.To read this article in full or to leave a comment, please click here
