VMware and Docker Deliver Greater Speeds through the Right Controls

This post was co-authored by Guido Appenzeller, CTSO of Networking and Security (@appenz), and Scott Lowe, Engineering DockerArchitect, Networking and Security Business Unit (@scott_lowe)

In today’s business environment, companies are being asked to go faster than ever before: faster time to market, faster response to customers, faster reactions to market shifts. Having a good idea isn’t enough; companies not only need to have a good idea, but they need get it to market fast, and quickly iterate on improvements to that idea. Speed is a competitive advantage.

The phenomenal success of the open source Docker project is a reflection of the pressure on companies to go faster. Companies across all industries have recognized that successful development teams can be a competitive differentiator. However, developers needed a way to simplify and accelerate the development and deployment of applications and code, and found Docker was one way to help accomplish that. Docker has won a place in the hearts and minds of many developers for its ability to help simplify the development and deployment of many different types of applications.

At the same time, companies face a bewildering array of security threats. Security and compliance remain as important as Continue reading

NASA: “Wild” technology will transform aviation

It’s not often you see a button-down organization like NASA call something “wild” but that’s what the space agency is calling six concepts – ranging from adding artificial intelligence to unmanned aircraft to using electricity for propulsion -- it has picked to study to revolutionize the aviation world.+More on Network World: Hot stuff: The coolest drones+The project, known as Convergent Aeronautics Solutions (CAS) is looking to develop what NASA called “something truly historic – the buzzword is ‘transformative’ – and help crack tomorrow's biggest challenges in aviation related to fuel use, the environment, and managing global growth in air traffic.”To read this article in full or to leave a comment, please click here

Docker’s Experimental Binary

Docker is an incredibly fast-moving project. As the project grows and acquires users, making changes becomes more complex. In particular, any patch that impacts user experience is a tough call. Each feature that Docker ships is immediately adopted by hundreds … Continued

Osaka, Japan: CloudFlare’s 35th data center

Move over Jurassic World, the long awaited sequel to our Tokyo deployment is here. Our Osaka data center is our 2nd in Japan, 5th in Asia (following deployments in Hong Kong, Tokyo, Singapore, and Seoul), and 35th globally. This latest deployment serves not only Osaka, Japan's second largest city, but also Nagoya, the 3rd largest, and the entire Keihanshin metropolitan area including Kyoto and Kobe. This means faster application delivery to the area's 30 million inhabitants, and full redundancy of traffic with our Tokyo facility. CloudFlare is now mere milliseconds away from all 110 million Internet users in Japan.

The Internet in Asia

Even though Asia is home to many of the most technologically advanced nations in the world, the delivery of Internet traffic across the region is hardly seamless. Many of the incumbent telecommunications providers in the region (e.g. NTT, Tata, PCCW, Hinet, Singtel, among many others) do not interconnect with one another locally. This is another way of saying that traffic is routed poorly in the region. Traffic sent from one network in Japan, for example, may have to pass through an entirely different country or, in some instances, even the United States, Continue reading

Even among poor, mobile Web is big in Africa

Eighty-seven million people in Nigeria browse the Internet on mobile phones, according to figures from the country’s telecom regulator that confirm that even among low-income people, the mobile Web is big in Africa.Nigeria is Africa’s largest telecom market by investment and subscription, followed by South Africa and Kenya. A just-released report from the Nigerian Communication Commission (NCC) on April Internet usage backs up findings from other sources showing that mobile Web use is widespread, including for people in low-income households, many of them living below the poverty line.About 25 percent of the people who use mobile phones to browse the Web in Nigeria, more than 22 million users, are from low-income households, according to an NCC official.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Researchers: Graphene could help increase chip speed by 30%

Here's another use for graphene—wrap transistor wires with it and boost computer chip speeds.Scientists have discovered that replacing tantalum nitride, the existing wire sheathing material between transistors, with graphene allows chips to exchange data faster.It's yet another use for this super-material. I've written about graphene before in a post titled "Materials breakthrough promises smaller chips."Thin graphite material If you're unfamiliar with this breakthrough material, graphene is the world's most conductive substance.

A case for compromise on Uber’s ‘contractor’ legal dispute

Uber ought to be on top of the world. The "ride-sharing" app has already raised more than $5 billion and is worth an estimated $50 billion. Just as important, it has reached the stage of ubiquity where people use its name as a verb: "Forget driving, we'll just Uber over to the event."And yet, a dark cloud is shadowing Uber's future, along with that of many other companies riding the wave of the so-called "sharing economy." Many of those companies' business models are built around workers classified as contractors, not employees, but it seems increasingly clear that no matter how convenient for Uber and its ilk, that classification is unlikely to stand up to judicial scrutiny. At least not without major changes in the law and the way these sharing-economy companies do business.To read this article in full or to leave a comment, please click here

Operational Annoyances: SSL Intermediate Certificates

Secure Certificate

You’re asked to update the SSL certificate for movingpackets.net on a load balancer. The requestor (me, I suppose) gives you the certificate, the private key and passphrase, and the intermediate bundle file provided by the certificate authority.

movingpackets.net.crt
movingpackets.net.key
movingpackets.net-intermediate-chain.crt

You faithfully go to the load balancer, upload the files, enter the passphrase, and create a client SSL profile referencing the cert/key/chain combination I provided, and all is well. The only thing is, you have 200 VIPs on the load balancer, mostly issued by the same certification authority (CA), so don’t they nominally share the same intermediate chain? (Hint: Almost certainly, yes)

Operational Annoyance

Here is the operational annoyance. The fact that the same intermediate certificate/chain has been uploaded 200 times with different names doesn’t stop things working, but it does seem rather inefficient. As far as I can determine, the F5 LTM load balancers (for example) actually concatenate all the uploaded certificates into a single bundle file and search the bundle when a certificate is referenced. I have no idea if there’s a huge performance gain here (unlikely), but it seems logical to want to minimize that file size regardless. On other Continue reading
