Comparing the performance of popular public DNS providers

ThousandEyes, a network intelligence company with the ability to monitor performance from hundreds of vantage points across the Internet, has insight into a variety of services across the globe, including public DNS service providers.  In this article we’ll dive into our results from testing 10 of the most popular public DNS resolvers, with the goal of helping you make informed conclusions about your choice of provider. We observed a wide range of performance across different services, both globally and from region to region.

The Domain Name System (DNS) is the internet’s system for converting alphabetic web addresses into numeric IP addresses. If a given service’s DNS records are unavailable, the service is effectively down and inaccessible to everyone.  DNS can also have a substantial impact on page load time and web page performance. While it’s just the first step of many in the page load process (see the below image), any increase in DNS lookup time will directly increase load times. DNS lookup time, in turn, is directly affected by latency to the DNS server.

Worth Reading: Value constrains us

I only take part in a few services, and I’m not consistently active on any of them. Despite however many followers I might have on a given platform, the world doesn’t care what I have to say on those services so much that my contributions especially matter. Therefore, stepping back isn’t harming anyone, nor is it disappointing someone that I’m not saying something or participating in every conversation that I might. No one notices. —Ethan Banks

IDG Contributor Network: Artificial intelligence tool fixes password weakness

Flaws in passwords can be eliminated with artificial intelligence (AI), say researchers. This includes identifying common words that hackers know, too. The mending is accomplished with AI-garnered analysis of existing insecure passwords, coupled with feedback to the user based on that. It makes password creation more reliable, say scientists from Carnegie Mellon University and the University of Chicago.+ Also on Network World: Vendors approve of NIST password draft + The group says it’s no good simply telling users their password isn’t secure when they attempt to create one—like the current password strength meters do using colored graphs. The meter should tell the creator what’s wrong with the secret word and advise how to conjure up a better one.To read this article in full or to leave a comment, please click here

Nvidia’s new Volta-based DGX-1 supercomputer puts 400 servers in a box

You won't need to buy a rack of 400 servers if you have one high-powered Nvidia DGX-1 supercomputer with a Volta GPU sitting on your desktop.The DGX-1 supercomputer -- which looks like a regular rack server -- gets most of its computing power from eight Tesla V100 GPUs.The GPU, the first one based on the brand-new Volta architecture, was introduced at the company's GPU Technology Conference in San Jose, California, on Wednesday."It comes out of the box, plug it in and go to work," said Nvidia's CEO Jen-Hsun Huang during a keynote speech.But the DGX-1 with Tesla V100 computer is expensive. At US$149,000, it's worth some people's life savings. But Huang encouraged people to order it, saying the box will ship in the third quarter.To read this article in full or to leave a comment, please click here

Microsoft’s new tools help devs manage cloud deployments on the go

Microsoft is making it easier for developers to manage their cloud deployments on the go, using a new mobile app and browser-based command line.On Wednesday, the company unveiled Azure Cloud Shell, which lets developers spin up a full-fledged terminal environment inside Microsoft’s cloud and comes with a set of preconfigured tools for managing deployments. Each user will have persistent file storage in their Cloud Shell, hosted in Microsoft Azure.Cloud Shells are accessible through the Microsoft Azure web portal, as well as the Azure mobile app for iOS and Android, which was just released Wednesday. That app also provides users with the ability to monitor the workloads they have running in Microsoft’s public cloud and perform basic management like stopping and restarting virtual machines.To read this article in full or to leave a comment, please click here

18 things you should know about using Linux tools in Windows 10

Last year Microsoft added an unusual new feature to Windows 10: Linux support. The Windows Subsystem for Linux (WSL) — sometimes called Bash on Windows — is “Microsoft’s implementation of a Linux-compatible infrastructure that runs atop and within the Windows kernel,” senior program manager Rich Turner tells CIO.com. That means running Linux binaries without leaving Windows.“Bash on Windows offers a toolset for developers, IT administrators and other tech professionals that want or need to run Linux command-line tools alongside their Windows tools and applications,” Turner explains. Developed with the help of Canonical (and a large community of Linux users), it’s not there to turn Linux into Windows, or Windows into Linux. It’s just that some Linux tools are so ubiquitous for development and deployment that it’s useful to be able to use them without spinning up a virtual machine (VM). That’s one of the reasons Macs are so popular with developers: MacOS is based on BSD, which is UNIX, so it can run Linux tools like Bash. And now, so can Windows 10.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Data virtualization: Like rocket fuel for your mainframe

It goes without saying that mainframes are powerful. These computers can perform more operations per second than any other commercial system, which is why most banks (not to mention many government agencies, insurance companies, retailers and other businesses that manage massive amounts of data) rely on Big Iron for their indispensable data analytics functions.And to say analytics are indispensable is underselling their value. Data analysis is an absolutely integral part of the new economy, and any organization seeking an edge needs an edge in analytics. Mainframes are a good match to provide the speed that leading companies are looking for, but many companies are still held back by their software.To read this article in full or to leave a comment, please click here

VMware unveils the latest nervous system for enterprise IoT

The internet of things seems tailor-made for management headaches. Having thousands of tiny devices distributed across a city or a company is hard enough. Then there's the whole infrastructure supporting them, including network connections and edge gateways.Some big players, including General Electric, Nokia, and Cisco's Jasper division, have products and services for running all this. Now VMware is taking on the challenge with VMware Pulse IoT Center, a solution that draws on two platforms the company already sells.To read this article in full or to leave a comment, please click here

IBM’s new PowerAI tools automate image recognition

IBM is trying to remove some of the complications related to image recognition with new tools to automate critical machine learning tasks.A major update of the company's PowerAI tools has a feature called AI Vision, an auto tuner that makes it easy to identify and classify pictures. It will also speed up image recognition by breaking down tasks over multiple clusters.AI Vision plays a big role in automating machine learning by creating a tuned model, said Sumit Gupta, vice president of machine learning.The software abstracts machine learning, and developers don't need knowledge of low-level access to frameworks to tune, train, and deploy image recognition models. It's much like programming a game to take advantage of GPUs without deep knowledge of low-level APIs.To read this article in full or to leave a comment, please click here
