HPE Tops Enterprise Data Center Hardware Market
Cisco and Microsoft are the leaders in the service provider and software data center sectors.
HTTP/2 Demo: Under the Hood
At first glance, the potential performance improvements of HTTP/1.1 versus HTTP/2 on our demo page may seem a bit hard to believe. So, we put together a technical explanation of how this demo actually works. We’d also like to credit the Gophertiles demo, which served as a basis for our own HTTP/2 demo.
Overview
A web page can only be served over either HTTP/1.1 or HTTP/2—mixing protocols is not allowed. Our demo page is HTTP/2-enabled, so there’s no way to load HTTP/1.1 content directly on the same page. Inline frames (iframes) can be used to solve this issue. We embedded two iframes on our demo page, both containing the same source code. The key difference is that one iframe loads over an HTTP/1.1 CDN while the other loads over an HTTP/2 CDN.
We chose Amazon CloudFront for the HTTP/1.1 CDN because it can only serve content over HTTP/1.1. For the HTTP/2 CDN, we’re using our own HTTP/2-enabled network. You can take a look at the individual HTTP/1.1 and HTTP/2 iframe content, which should have similar load times to the side-by-side example on our demo page.
Iframe Content
So, what is contained in Continue reading

By Mark Haranas
It seems everyone was trying to shake up the traditional networking world this year through faster, cheaper, software-driven solutions. Startups are saying 2015 is the year where software-defined networking (SDN) and the Internet of Things (IoT) began to hit the mainstream market. Innovators who hailed from networking leaders like Cisco and Juniper Networks are forming new companies focusing on things such as analytics, “X”-as-a-Service or converged infrastructure. Startups such as Versa Networks, founded by former Juniper top engineers, and Altocloud, started by a former Cisco top executive, are striving to make network solutions simpler, automated and more cost effective to drive business outcomes. Here are 10 networking startups that have shaken up the industry in 2015.Plexxi is seeking to change the networking world in the enterprise and service provider markets by creating underlays that enable the network to be as scalable and easy to use as a cloud environment.
The Stack: How SDN can help enterprises become a competitive force in the digital age
By Kalyan Kumar, Senior Vice President and Chief Technologist at HCL Technologies
With the digital age dawning, businesses are under mounting pressure to become more agile if they want to compete. This has led to a huge focus on cloud, big data and mobile, but what is often forgotten is that these digital services are delivered on an underlying network infrastructure. Failing to future-proof this platform could ultimately render investments in new technologies ineffective and reduce the benefits they deliver. Digital services require a platform that can scale with spikes in traffic while being able to adapt to changing traffic patterns in real time. Traditional network infrastructures are unable to provide the agility, elasticity and scalability needed to keep up with rapid digital transformation. In order to tackle this challenge effectively, businesses must transition from physical infrastructure to implement a software defined network (SDN) that is more aligned with modern business demands.
Data Center Knowledge: Why Hyperconverged Infrastructure is so Hot
By Yevgeniy Sverdlik
Hyperconverged infrastructure did not exist as a concept two or three years ago. Today, it is one of the fastest-growing methods for deploying IT in the data center, as IT departments look for ways to adjust to their new role in business and new demands that are placed on them. Gartner expects it to go from zero in 2012 to a $5 billion market by 2019, becoming the category leader by revenue in pre-integrated full-stack infrastructure products. The category also includes reference architectures, integrated infrastructure, and integrated stacks. “Hyperconvergence simply didn’t exist two years ago,” Gartner analyst Andrew Butler said. “Near the end of this year, it’s an industry in its own right.” But, he added, the industry has a lot of maturation ahead of it, which means far from all vendors who are in the space today will still be in it a few years from now. In a session at this week’s Gartner data center management summit here, Butler and his colleague George Weiss shared their view of what hyperconverged infrastructure is, why it’s so hot, and what might it all mean for data center managers.
eWeek: Enterprises Embracing Next-Generation Data Centers, Gartner Asserts
By Scot Peterson
Amid the growth of cloud computing and software as a service, the enterprise data center seems like it has lost its place to become a repository of outdated modes of operation and aging equipment ripe for replacement. The general impression is that the enterprise data center as we know it is dead. Long live the data center. Call it the enterprise-defined data center. The reality is that data centers will continue to exist. But they are quickly changing into hubs of innovation, smaller and more agile. This is something that we have seen coming, but now the trend is here. Data centers are changing under the feet of companies as they transform themselves around digital business models, which Garter analysts call “Mode 2” computing. “It’s an exciting time to be in infrastructure,” said Vijay Luthra, senior vice president, global head of infrastructure, engineering and operations at Northern Trust, a speaker here at the Gartner Data Center, Infrastructure and Operations Management Conference. “CIOs are looking at very disruptive models.”
Harvard Business Review: 8 Tech Trends to Watch in 2016
By Amy Webb
More than once you’ve probably looked at some new digital or technological development and asked yourself, “How did we miss that?” In order to chart the best way forward, you must understand emerging trends: what they are, what they aren’t, and how they operate. Such trends are more than shiny objects; they’re manifestations of sustained changes within an industry sector, society, or human behavior. Trends are a way of seeing and interpreting our current reality, providing a useful framework to organize our thinking, especially when we’re hunting for the unknown. Fads pass. Trends help us forecast the future. To identify emerging trends, I use a six-part methodology beginning with seeking out those on the fringes doing unusual experimentation or research. Next I look for patterns using my CIPHER model, where I identify previously unseen contradictions, inflections, practices, hacks, extremes, and rarities. Then I ask practical questions, mapping trajectories, building scenarios, and pressure-testing my conclusions.

Gauging service quality in an SDN/NFV network requires looking at every layer that makes up your application.Transforming ideas into light bulbs – LiFi
About 4 years ago, Harald Haas, a physicist and professor of mobile communications at the University of Edinburgh, was the first to coin the term Li-Fi, at a TED Talk during TEDGlobal 2011. Since then, millions of bits about this technology roamed the Internet, and many companies already started implementing it.
Who’s doing this already?
The history begins with a company named Velmenni, which has produced a light bulb that works with Li-Fi technology on a small scale. They are not the first to prove the technology works, nor the first to conduct a real-world experiment, but here’s their Jugnu Lighbulb demo.
Philips has developed a VLC (Visible Light Communication) system for shoppers at stores. People have to download an app on their smartphone and then it will interact with the LEDs in the store. The LEDs can pinpoint their location in the store and give them corresponding coupons and information based on which aisle they are on and what they are looking at.
ByteLight has developed a system similar to Philips’ lighting network, making LEDs “talk” to any smartphone and tablet with a camera and/or Bluetooth Smart technology that is “opened to listen”.
The first VLC smartphone prototype was Continue reading
