America’s first exascale supercomputer set for 2021 debut

The next step up in supercomputer performance is exaflops, and there is something of an arms race between nations to get there first — although it’s much more benign than the nuclear arms race of the last century. If anything, it’s beneficial because these monster machines will allow all kinds of advanced scientific research. An exascale computer is capable of processing one exaflop, one quintillion (1,000,000,000,000,000,000) calculations of floating point operations per second. That’s about a trillion times more powerful than a consumer laptop. + Also on Network World: Texas goes big with 18-petaflop supercomputer + China has said it will have an exascale computer by 2020, one year sooner than the U.S.To read this article in full or to leave a comment, please click here

Why it pays to spend more on premium people

To spend, or not to spend — that is the question. Whether it’s wiser to invest in the latest and most-hyped hardware and suffer the great misfortune of mediocre talent, or to take the hit and invest in greater minds, and thus end troubles. We can wax poetic for much longer on the many dilemmas that accompany partitioning a budget, but we think our time is better spent providing an actual solution. The reality is that too much of funding is spent on hardware, and not enough is spent on investing in the people who make the technology mean something. In this blog post, we’ll help you understand the benefits of investing more money in employees, and then show you how you can reduce your TCO so that you can stop overspending on hardware and start investing in premium people.

What are the benefits of investing in people?

It pays to invest in people who can really make your company great. In fact, failing to properly invest in your hires can actually cost your company. A study in 2013 showed that seventy percent of American workers were actively disengaged at their job, which cost businesses more than $450 million. So, Continue reading

The Internet Society’s 25th Anniversary and the Renewal of Commitment

Last week was a proud and memorable moment for us at the Internet Society as we celebrated our 25th anniversary in Los Angeles. In addition to the well-known Internet Hall of Fame award ceremony and the annual InterCommunity 2017 event, this year’s event also had a dialogue on topics from  the 2017 Internet Society Global Internet Report: Paths to Our Digital Future and introduced the 25 under 25 award ceremony, which celebrated inspiring and remarkable ideas and projects that young and motivated entrepreneurs in the Internet space have initiated.

I was equally, however, touched by the strong drive and energy in the Internet Society leadership and staff, whose efforts and attention to detail have been clearly visible throughout the two-day event. The joyful spirit demonstrated by the Internet Society team at the Brussels interactive node helped ensure that the 15-hour InterCommunity 2017 marathon covering 16 interactive regional nodes was truly a global conversation. Using the Internet to connect those nodes demonstrated one practical application of the Internet to run a global event with precision and high productivity. Furthermore, the positive mood at Brussels appeared to be quite contagious as reflected by the celebrations that took place in at least another 55 Continue reading

IDG Contributor Network: Addressing the Great IoT Analytics Skills Gap

Expect to see a huge uptick in demand for people who have technology and business skills related to the Internet of Things (IoT), as organizations continue to ramp up their IoT projects in a big way.A new report by 451 Research notes that finding IoT-skilled workers is a big challenge. Nearly half of the 575 IT and IoT decision makers the firm surveyed, primarily in North America and Europe, said they face a skills shortage for IoT-related tasks.The skills companies need to acquire include expertise in areas such as cyber security, networking, device hardware, applications, and overall management of IoT strategy. But perhaps nowhere will demand be greater in the coming years than in areas related to data analytics. As companies seek to use IoT data to predict outcomes,  prevent failures, optimize operations and develop new products, advanced analytics competency—including artificial intelligence (AI) and machine learning (ML)—will be critical to their success.To read this article in full or to leave a comment, please click here

How Should We Handle Failure?

I had an interesting conversation this week with Greg Ferro about the network and how we’re constantly proving whether a problem is or is not the fault of the network. I postulated that the network gets blamed when old software has a hiccup. Greg’s response was:

Which led me to think about why we have such a hard time proving the innocence of the network. And I think it’s because we have a problem with applications.

Snappy Apps

Writing applications is hard. I base this on the fact that I am a smart person and I can’t do it. Therefore it must be hard, like quantum mechanics and figuring out how to load the dishwasher. The few people I know that do write applications are very good at turning gibberish into usable radio buttons. But they have a world of issues they have to deal with.

Error handling in applications is a mess at best. When I took C Programming in college, my professor was an actual coder during the day. She told us during the error handling Continue reading

Weird IP networks: Internet via birds and ham radios

Reliable (mostly). Boring.What happens when that infrastructure goes down? Maybe the power goes out somewhere along the network. Maybe a cell tower gets attacked by Godzilla. Who knows? Dangers lurk around every corner. + Also on Network World: When disasters strike, edge computing must kick in + In those cases, when your traditional network connection fails you, you're going to need a backup. Something to get you back up, online and moving data around.

IDG Contributor Network: 5 myths surrounding rugged IoT testing

Today’s tech-hungry consumers and innovative producers wouldn’t be able to enjoy the IoT without all the rugged testing necessary to ensure products can handle the stress they’ll endure daily. Yet while many companies and consumers alike pride themselves on the vitality of their equipment, however, many egregious myths about rugged IoT testing still endure.So, what are the five common myths that most-often surround rugged IoT testing, and who’s responsible for creating and proliferating these rumors? A quick review below shows some of the nastiest of these myths, and why they should be avoided.1. Going beyond specification limits if a waste of time In many test labs, the mainstream logic is that IoT products don’t need to be tested past their specification limits. Consumers won’t really care, the faux-logic insist, and it would be a waste of time and resources to try and push devices past their commercial limits.To read this article in full or to leave a comment, please click here

Viptela SD-WAN Solution – Cisco Systems Company

Before starting with the SD-WAN solution. I would like to talk about Fabric a little bit, So Fabric is a cloud delivered network that is secure, scalable, open and simple to deploy and if we talk about the Viptela Fabric solution, it enables an Enterprise to extend its network footprint to all infrastructure elements using a single platform. This includes branches, campus, remote sites, Cloud and data center.

What is the basic feature of the Fabric enabled SD solution ?
So SD-WAN so called Software Defined WAN solution, where control plane or management plane is separated from the physical devices, while in the Viptela solution we have following architecture, where we have data-plane on the physical devices (obviously), Control Plane by VSmart or VBond Management tool, Management Plane via VManage and Orchestration plane.

So below is the high level architecture view of the Viptela Managed SD-WAN solution

Fig 1.1- Viptela SD-WAN Solution
The traditional WAN challenge is to connect various sites, branches, stores, remote-locations, campuses and DCs. This network to be sophisticated with routing, path selection, security, segmentation etc.

Connectivity to the cloud

In the today's era everyone wants to connect to the cloud and want to access the application on the Continue reading

Code Everywhere: Why We Built Cloudflare Workers

It all comes down to the speed of light. It always does. The speed of light limits the latency possible between someone using the Internet and the application they are accessing. It doesn’t matter if they are walking down the street hailing a car using a ride-sharing app, sitting in an office accessing a SaaS application on the web, or if their wearable device is reporting health information over WiFi. The speed of light is everywhere.

When you can’t fight the speed of light you only have one possible solution: move closer to where the end users are. In simplistic terms, that’s what Cloudflare has done by building its network of 117 data centers around the world. We’ve cut the latency between users and servers by moving closer.

But to date all we’ve moved closer are things like SSL handshakes, WAF processing of requests and caching of content. All those things help make Internet applications faster and safer, but there’s a huge missing component... code.

The code that makes Internet applications work is still sequestered in servers and cloud services around the world. And there are only a limited number of such locations even for large cloud Continue reading
