How Cisco’s Multigigabit Technology can increase network speeds

If you remember, in a previous Switch IT Up blog post I referenced Wireless AC and Wave 2 — some of the things that we could expect and some of the problems we could run up against. Things like having enough bandwidth to our APs to support a 6.8 gig connection.So, what can be done about that?Well, in 2015, Cisco introduced its Catalyst Multigigabit Technology, along with a new group of products, that address that issue and allow users to get more than just that 1 gig speed that most people have in their closets or in their infrastructure. How can users leverage that and still use their preexisting infrastructure rather than having to rip everything out and replace it?To read this article in full, please click here

Martin Casado on the Future of Networking

In this video, software-defined networking pioneer Martin Casado, a general partner at VC firm Andreessen Horowitz, talks about how he expects enterprise networking will adopt SDN. He also explains how he sees traditional IT functions such as networking as key to IoT and the massive expansion of technology in every industry.  

Here’s what the big four U.S. mobile ISPs are doing with IoT

The Internet of Things is a business phenomenon at least as much as it is a technological one, which means that every company in the world with a possible angle on IoT is doing its best to claim a piece of the large and growing pie. In the case of the big four U.S. mobile data providers, the trick is selling more than just connectivity.To talk about the big four as a single entity, however, is slightly misleading. The bigger two – AT&T and Verizon – have a considerable lead in customer reach and technological maturity over T-Mobile and Sprint, with both of the former companies on track to deliver about $1 billion in IoT-related revenue in 2018, according to 451 Research vice president Brian Partridge.To read this article in full, please click here

Worth Reading: Manual Work Is a Bug

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

Tom Limoncelli wrote a great article about starting an automation journey from sysadmin perspective. Not surprisingly, his recommendations aren’t that far off from what I’m telling networking engineers in my network automation presentations, Network Automation 101 webinar, and introductory part of Building Network Automation Solutions online course:

Check Out Our New Overview of Microsoft Azure Course!

Maybe your company has decided to move to the Cloud and you need to know what Azure is and how to create resources, or maybe you want to learn Azure so you can add it to your resume.  Either way, this short course will explain what Azure is, the difference between PaaS and IaaS, and how to create resources in Azure.

 


Why You Should Watch

This simple step-by-step class will teach you the basics of Cloud services and provide a solid foundation of knowledge to build on. Given the amount of services available on Azure, it would be impossible to learn each one with just one class, so this course covers the basics of storage, networking, virtual machines, SQL databases, and web apps. Through the discussion of these 5 topics, we can effectively demonstrate how Azure works and how to set up different services in Azure.


What You’ll learn

After viewing Overview of Microsoft Azure, you will have a basic understanding of Azure and its abilities, and be better prepared for the Azure exams.

How to speak Linux

I didn’t even stop to imagine that people pronounced Linux commands differently until many years ago when I heard a coworker use the word “vie” (as in "The teams will vie for the title") for what I’d always pronounced “vee I”. It was a moment that I’ll never forget. Our homogenous and somewhat rebellious community of Unix/Linux advocates seemed to have descended into dialects – not just preferences for Solaris or Red Hat or Debian or some other variant (fewer back in those days than we have today), but different ways of referring to the commands we knew and used every day.The "problem" has a number of causes. For one thing, our beloved man pages don't include pronunciation guidelines like dictionaries do. For another, Unix commands evolved with a number of different pronunciation rules. The names of some commands (like "cat") were derived from words (like "concatenate") and were pronounced as if they were words too (some actually are). Others derived from phrases like "cpio" which pull together the idea of copying (cp) and I/O. Others are simply abbreviations like "cd" for "change directory". And then we have tools like "awk" that go in an entirely different direction by Continue reading

What Qualcomm’s rumored exit from data centers means

The tech industry got a jolt last week worse than the 3.5 magnitude quake that hit Oakland, California, on Monday. A report by Bloomberg, citing the usual anonymous sources, said that after a whole lot of R&D and hype, Qualcomm was looking to shut down or sell its Centriq line of ARM-based data center processors.Qualcomm launched the 48-core Centriq 2400 last November. At the time, potential customers, such as Microsoft, Alibaba and HPE, took to the stage to voice their support and interest.To read this article in full, please click here
