We’re Flipping Learning in Texas: Tech Trends in Action

September 5, 2013 at 3:19 pm PST

What if we could change learning in the classroom to better suit students’ needs and accommodate individual learning styles? That’s exactly what Denton Independent School District in Texas is doing through flipped learning and collaborative video technology.

In his recent blog, Barry Fox describes what the future of education looks like at Denton ISD, and the potential for other school districts throughout the country to adopt a similar model. Through flipped learning, students experience a rich virtual classroom experience, with video-based material made available to students from any location through multiple devices, bringing learning beyond the classroom. This provides the flexibility desired by students, enabling them to easily connect with teachers, re-watch content and learn at their own pace.

Help us share the Denton ISD story of championing student-teacher relationships at next year’s SXSW. Vote for our panel at http://panelpicker.sxsw.com/vote/23959.

Why virtualizing the Network is not the same as virtualizing the Server?

VMware launched NSX, its Network Virtualization platform at VMworld last week. In his keynote, VMware CEO Pat Gelsinger portrayed Network Virtualization as a very natural extension to what VMware accomplished in Server Virtualization. However market fundamentals and early drivers for Server Virtualization are not quite the same as Network Virtualization. Hence any comparison and contrast between the two should be understood and weighed on in their respective contexts.

The drive for Server Virtualization fundamentally was an attempt to address the growing gulf between faster rate of technology advancement in server space relative to customer ability to utilize the excess capacity. It was a trend that was driven by the focus towards gaining efficiency in an era where cost was becoming important. Over nearly a decade now Server Virtualization has accomplished this goal of better utilization of assets:  And server utilization levels have increased by a factor of 4 over the years.

Networks in the data centers today however do not suffer from this excess capacity problem. If any, the problem is the reverse – user demand for networks capacity continues to outpace what is currently available. As long as there remains a growing gulf between user expectations for capacity relative to technology advancement there will remain opportunity for vendors to innovate in this space. In other words unlike the server world, network virtualization does not shift the value away from the underlying infrastructure.

Server Virtualization is transforming IT by providing greater business agility. Goal of Network Virtualization should be to bring similar business agility for the network. However, this goal need not require complete decoupling of the virtual network from underlying physical network as some vendors may lead you to believe. Any goal of gaining agility by completely decoupling physical and virtual network can only be done with some confidence, by significant under-provisioning of the physical network. For if the bandwidth is plenty the overlays have less dependency on understanding or integrating with the underlying infrastructure. This shortsighted approach, which focuses on business agility, but ignores business assurance, will increase the network capital expenditure and operating expense spend over time. Note that even in the server world where compute efficiency was attained, the benefit did not come at any capex or opex savings. Capex savings attained on server hardware was offset by increased cost of virtualization software. And we have seen opex continues to increase over the last decade.

As IT increasingly begins to take on a service centric view, more intelligence will be needed at the edge – physical or virtual edge.  Cisco’s launch of Dynamic Fabric Automation (DFA) last July, address this view of an optimized fabric infrastructure with a more intelligent network edge that can enable any network anywhere, supporting transparent mobility for physical servers and virtual machines. Application Centric Infrastructure (ACI) takes this a step further by enabling application-driven policy automation, management and visibility of physical and virtual networks. They however also integrate the physical and the virtual network for an agile service delivery that also assures full lifecycle user experience.

#ExecInsights: Top Five Ways The Internet of Everything Can Be Realized Today

Last week, I presented at the Colorado Innovation Summit in Denver, Colorado where leaders from higher education, industry, start-ups, government, and research labs came together to discuss a wide array of innovation topics such as technology, education, social entrepreneurship and economic development.  The need to transform and revitalize communities around the world to make public services and communications anywhere and on any device more accessible was one of the hot topics.

Today, we are experiencing the largest economic and social shifts in history including an aging population – countries like the U.S., Japan and China are going to see its elderly population over 65 years old more than double before the year 2050.  As a result, millions of new jobs will need to be created and productivity needs to be significantly increased to absorb the burgeoning working-age population.   We are also observing other shifts: economies are shrinking in Europe, Germany and Russia while economies like Nigeria and Saudi Arabia and Egypt are seeing hyper-growth numbers. In both these economic situations, increasing productivity to increase income and overall living standards is vital.  These and other trends we call the Internet of Everything (IoE) highly resonated with attendees as they saw that having the ability to anticipate customer needs and how to solve their problems creates a huge opportunity for global companies.

An Internet of Everything Startup Spotlight: John Funge, Co-Founder & CEO, BrightContext

Today I’m introducing a new series that focuses on the collective power of connections in the Internet of Everything (IoE) — and some of the new companies that are creating value from those connections. The industry is ripe with emerging IoE-focused startups that deserve to be recognized for their work in building the Internet of Everything, brick by web-enabled-brick. These various startups are making an impact in education, healthcare, home automation and more. They are led by thinkers and doers who are helping to create the future. Periodically over the next several months, we’ll take a look at some of these startups and learn more about how IoE is enabling their success — and how they, in turn, are enabling the Internet of Everything.

Recently, we had a chance to talk with John Funge, co-founder and CEO of BrightContext, a cloud-based data-stream processing platform that is helping to turn Big Data into actionable insights. Here’s how BrightContext is pioneering the growth of the Internet of Everything:
