Worth Reading: Lessons from Facebook’s split network backbone

Distributed applications, whether they are containerized or not, have a lot of benefits when it comes to modularity and scale. But in a world of feature creep on all applications, whether they are internally facing ones running a business or hyperscale consumer applications like Google’s search engine or Facebook’s social media network, these distributed applications put a huge strain on the network. This, more than any other factor, is why network costs are rising faster than any other aspect of the datacenter. —The Next Platform

HPE offers an escape from the aging HP-UX OS via containers

Hewlett Packard Enterprises' HP-UX OS has been around for more than 30 years, and users may be looking to move on from the Unix-based OS.Now HPE is offering a way out of the ancient OS using containers, which are small buckets running instances of applications. The containers will be offered with the Linux OS.HPE will provide containers to transition from conventional mainframe-style OSes to new hardware like x86-based Xeon servers. In this case, HPE is trying to get users to transition from Itanium chips.Intel started shipping its last Itanium 9700 chips -- codenamed Kittson -- on Thursday. Correspondingly, HPE announced new Integrity i6 servers with the new chips. But the future of HP-UX servers is uncertain because Intel has no new Itanium chips beyond Kittson.To read this article in full or to leave a comment, please click here

Bringing Internet to Venezuela’s Remote Regions – While Setting a World Record

My interest in networking began during my time as a professor and head of the telecommunications lab at the University of Los Andes, in Merída, Venezuela, where we began experimenting with computer networks. I was one of the earliest Internet enthusiasts at our university.  Our university was the first in Venezuela to get direct access to the Internet backbone in Homestead, Florida, by means of an antenna on the roof of our lab with the satellite modem in my office.

Twenty years after Deep Blue, what can AI do for us?

On May 11, 1997, a computer showed that it could outclass a human in that most human of pursuits: playing a game. The human was World Chess Champion Garry Kasparov, and the computer was IBM's Deep Blue, which had begun life at Carnegie Mellon University as a system called ChipTest.One of Deep Blue's creators, Murray Campbell, talked to the IDG News Service about the other things computers have learned to do as well as, or better than, humans, and what that means for our future. What follows is an edited version of that conversation.IDGNS: Is it true that you and Deep Blue joined IBM at the same time?To read this article in full or to leave a comment, please click here

Puppet zeroes in on containers, cloud workloads

Devops platform provider Puppet has introduced its Puppet Cloud Discovery service for learning what, exactly, users have running in the cloud and their impact.As Puppet's first foray into SaaS, the service offers visibility into cloud workloads, providing the same type of introspection as the on-premise Puppet Enterprise platform. For example, it can tell users if they might have vulnerabilities because they're running an outdated version of OpenSSL, or it could inform users which virtual machines need to migrated when moving from Windows Server 2012 to 2016.[ Download the Deep Dive: Monitoring in the age of devops. | Get a digest of the day's top tech stories in the InfoWorld Daily newsletter. ] Cloud Discovery will debut in a preview form on the Amazon Web Services cloud later this month; plans call for it to eventually be supported on other cloud platforms as well.To read this article in full or to leave a comment, please click here

Why digital disruption leaves no room for bimodal IT

Saying bimodal IT is dead may be a tad premature. But as digital disruption continues to sweep across sectors -- driven by companies such as Amazon.com, Uber and Airbnb -- two-speed IT is beginning to look and feel antiquated. Some CIOs and consultants argue that the operating model hinders innovation at a time when companies must accelerate their digital initiatives.Introduced by Gartner in 2014, bimodal IT splits technology departments into two groups: a stable mode (Mode 1) where the bulk of technology is carefully cultivated and refined and a second mode (Mode 2) that espouses experimentation, free-thinking and agility. Forking IT into separate tracks made sense a few years ago, as many CIOs worked to plug gaps in talent, process and technology, Forrester Research analyst Matthew Guarini tells CIO.com.To read this article in full or to leave a comment, please click here

Latest firmware updates for Asus routers fix CSRF security flaws

Users of Asus RT-N and RT-AC series routers should install the latest firmware updates released for their models because they address vulnerabilities that could allow attackers to hijack router settings.The flaws were discovered by researchers from security consultancy outfit Nightwatch Cybersecurity and leave many Asus router models exposed to cross-site request forgery (CSRF) attacks.CSRF is an attack technique that involves hijacking a user's browser when visiting a specially crafted website and forcing it to send unauthorized requests to a different website -- or in this case, the router web-based administration interface accessible over the local area network (LAN).To read this article in full or to leave a comment, please click here
