Resource Contention In IT – Time Is Never Enough

I’m at Future:NET this week and there’s a lot of talk about the future of what networking is going to look like from the perspective of vendors like Apstra, Veriflow, and Forward Networks. There’s also a great deal of discussion from customers and end users as well. One of the things that I think is being missed in all the talk about resources.

Time Is Not On Your Side

Many of the presenters, like Truman Boyes of Bloomberg and Peyton Maynard-Koran of EA, discussed the idea of building boxes from existing components instead of buying them from established networking vendors like Cisco and Arista. The argument does hold some valid ideas. If you can get your hardware from someone like EdgeCore or Accton and get your software from someone else like Pluribus Networks or Pica8 it looks like a slam dunk. You get 90% to 95% of a solution that you could get from Cisco with much less cost to you overall.

Companies like Facebook and Google have really pioneered this solution. Facebook’s OCP movement is really helping networking professionals understand the development that goes into building their own switches. Facebook’s commitment is also helping reduce the price of the Continue reading

Down to the WireX

Over the course of the last few weeks, a botnet comprised mainly of Android mobile devices has been utilized to launch a high-impact DDoS extortion campaign against multiple organizations in the travel and hospitality sector. This botnet, dubbed ‘WireX’, is only the second mobile botnet […]

Worth Reading: Multitasking without Thrashing

Human context switching is more complicated than computer context switching. Whereas the computer context switch replaces a fixed number of bytes in a few CPU registers, the human has to recall what was “on the mind” at the time of the switch and, if the human was interrupted with no opportunity to choose a “clean break,” the human has to reconstruct lost short term memory. —Peter J. Denning @Communications of the ACM

IoT privacy: 30 ways to build a security culture

Much work still must be done before the industrial and municipal Internet of Things (IoT) becomes widely adopted outside of the circle of innovators. One field, privacy, well understood by the public and private sector in the context of the cloud, PCs and mobile, is in the early stage of adaptation for the IoT.The sheer volume of data that will be collected and the new more granular architecture of the IoT present new privacy concerns that need to be resolved on an equal scale as the platform’s forecasted growth.A demonstration of this new aspect of privacy and compliance is the Privacy Guidelines for Internet of Things: Cheat Sheet, Technical Report (pdf) by Charith Perera, researcher at the Newcastle University in the U.K. The nine-page report details 30 points about implementing strong privacy protections.

What are the changes in August 2017 CCDE Practical exam ?

What are the changes in 2017 CCDE Practical/Lab exam ?    As you might know, CCDE Practical/Lab exam was cancelled on May 2017 due to some leakage. Some people tried to sell the scenarios, Cisco cancelled the exam and revoke the certifications of those who involved with that cheating. Some people among them can be […]

IDG Contributor Network: 2 myths I believed about Disaster Recovery as a Service

Maybe it’s because I’ve been married 16 years. Maybe it’s because we have 4 young children. Whatever the reason, at 42 years old, I’m slowly learning something about myself.I’m sometimes… wrong. [gasp]And when I notice it, it’s much better to admit it than make up an excuse. Can you relate?So, here is how this matters to you… I was wrong about Disaster Recovery as a Service (a.k.a. DRaaS). [bigger gasp]As the CEO of a business cloud and telecom brokerage, DRaaS is something I’ve heard about for a long time. But for a couple of years, I dismissed it. I didn’t think it was a fit for the majority of our clients (i.e. small- and medium-sized companies).To read this article in full or to leave a comment, please click here
