SDN & OpenFlow Create a More Efficient Data Center, Heavy Reading Finds

As SDN and OpenFlow controllers work together, data centers will become more efficient, says Heavy Reading IP Services Insider

BOSTON, Dec. 10, 2012 /PRNewswire/ --Software-defined networking (SDN) and OpenFlow controllers together will allow for more efficient services from data center operators, according to the latest report from Heavy Reading Insider (, a subscription research service from Heavy Reading (

OpenFlow Controllers: Implementing SDN in the Data Center examines the OpenFlow protocol, how it works, what's driving its adoption and where it's headed. It also compares controllers from five vendors, all of whom would like to see their technology become the preferred platform for developing SDN applications like the data center's first killer app: virtual networks.

For a list of companies covered in this report,

"The whole point of SDN is to help service providers and enterprises accomplish tasks such as network configuration and provisioning, load balancing and security policy enforcement more quickly, more efficiently and less expensively through automation," says Dawn Bushaus, research analyst with Heavy Reading Insider and author of the report. "The goal is to get away from having to program all the switches and routers in a network manually, and that means centralized software control is necessary."

Perhaps the most exciting and encouraging thing about SDN is the fact that network operators and service providers are finally not dependent only on vendors for innovation, Bushaus says. "Data center operators should expect to see plenty of activity in the controller market during the coming year," she continues. "There will be more mergers and acquisitions as hardware vendors look to acquire the pieces of the SDN puzzle they don't have. Startups will also come out of stealth to explain in detail where they fit in an OpenFlow environment, and incumbent equipment vendors likely will be forced to incorporate OpenFlow into their product portfolios whether they want to or not."

Key findings of OpenFlow Controllers: Implementing SDN in the Data Center include the following:

  • ONF and SDN have spawned software startups looking to cash in with controllers, switches and applications
  • Equipment vendors are scrambling to articulate a clear SDN message, with the products to back it up
  • OpenFlow may not be the de facto protocol for controlling software to communicate with networking elements in an SDN, but it has momentum
  • OpenFlow and SDN will remain center stage during the coming year
  • By incorporating the controller and v-switch into data centers, operators can begin to deliver services more quickly and efficiently, while cutting capex and opex
  • Data center operators should expect to see plenty of activity in the controller market in the coming year, including M&A activity as vendors pursue the missing pieces of the SDN puzzle

The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...
