Software Defined Networking, Cisco Style

As new technologies emerge and replace traditional ones, IT teams are discovering that building an infrastructure around new functionality is advantageous in a slew of ways.

One such disruptive technology gaining ground is software defined networking, or SDN.

The premise of SDN is to allow the user to determine how the network behaves by decoupling the control plane from the data plane. Control planes are essentially the “data directors,” instructing the data plane on where to transfer packets of data. The data plane then establishes the best path and carries the data to its destination. By separating these two functions, the user can program the open-source network to act in accordance with business requirements—using a central management interface in a vendor-neutral manner.

Not only has Cisco joined the SDN approach, they’ve gone beyond the basics of SDN to include an application-driven infrastructure. It’s called, appropriately, Cisco Application Centric Infrastructure, or Cisco ACI.

Cisco ACI combines hardware, policy-based control systems, and software to deliver management automation, programmatic policy, and dynamic workloads. It’s built around the application, not the network.

What’s the advantage? Doing so enables greater support for scalability, a more dynamic network, and centrally-defined portable policies—all of which lend to faster application provisioning and a more efficient environment.

While many SDN solutions are focused solely on software and virtualization, the reality is that hardware still exists and is an integral part of the network. Cisco ACI leverages existing hardware—because no matter how de-emphasized it may become, the physical infrastructure remains important.

As Cisco senior vice president of marketing Soni Jiandani tells Unleashing IT, “ACI is SDN plus a whole lot more. Other SDN models stop at the network. ACI extends the promise of SDN—namely agility and automation—to the applications themselves. Through a policy-driven model, the network can cater to the needs of each application, with security, network segmentation, and automation at scale. And it can do so across physical and virtual environments, with a single pane of management.”

And Shashi Kiran, senior director of market management at Cisco, shares his views on Cisco ACI in this blog.

As businesses are becoming more dependent on applications, they must stay competitive and relevant by considering updating their infrastructure to speak directly to the needs of the application. Learn more in this edition of Unleashing IT, a special release focused on Cisco ACI -- produced by Cisco and Intel® - and see how early adopters are realizing the benefits it brings to the table.

How Is Cisco IT Benefiting from Application Centric Infrastructure?

Cisco IT has already started reaping the benefits of Application Centric Infrastructure (ACI) from our early internal deployments. Cost savings rank high, in decreased operating expenditures through automation enabled by ACI and the sharp reduction of manual processes that introduce human errors and operational risk.   Read More »

Unleashing IT magazine Profiles Early adopters of Cisco ACI

 

Application Centric Infrastructure Special Edition

Application Centric Infrastructure Special Edition

It has been just a few short weeks since the Cisco Application Policy Infrastructure Controller (APIC) began shipping, building upon the availability of the Nexus 9000 series and laying the foundation for Application Centric Infrastructure (ACI).  The feedback from early adopters has been quite positive. As of August 13th, 2014 we had over 580 Nexus 9000/ACI customers and over 60 have bought the APIC within just two weeks.  We are highly encouraged by the momentum and are looking to build upon this over the course of our next fiscal year.

Recently, IT leaders have been talking about how software-defined networking (SDN) will usher new levels of business agility into their IT organizations, and it’s clear based on our early results that ACI not only delivers on these expectations but takes a leadership stance in delivering the industry’s best SDN solution.It is therefore a great time for us to take a look at these early adopters, explore and share their motivations for choosing the ACI approach.  Customers are genuinely excited with the open architecture and the flexibility and cost savings they get with a true systems approach and it is pertinent to understand their business challenges, architectural expectations and benefits they hope to receive over time.

To create a forum for these stories, we’ve produced a special edition of Unleashing IT -- a publication I’m very excited to share with you as it sheds light on what I truly believe is a transformative innovation.

Cisco ACI Fabric Simplifies and Flattens Data Center Network

On July 18th, Cisco IT turned on the first deployment of Application Centric Infrastructure (ACI) fabric at its engineering data center in San Jose. By using ACI fabric to simplify and flatten the data center network, we can reduce network operating costs as much as 55 percent and incident management roughly 20 percent. Take a peek at the ACI fabric inside our engineering data center:  Read More »

The Future of Networking, Available Today

I am Soni Jiandani, SVP of Marketing for Cisco’s Insieme Business Unit. Together with a team of veteran leaders and engineers, we continue to disrupt markets to drive industry transformation. Our latest disruption is focused on leapfrogging Software Defined Networks (SDN) with a holistic approach to the future of networking: Application Centric Infrastructure, or ACI for short.

My blog is timed with announcing the shipment of ACI – namely the Application Policy Infrastructure Controller (APIC) with ACI mode for the Nexus 9000.  But this is not a corporate sales blog. My intent is to foster an open discussion about the future of the networking industry.

ACI: A key enabler to driving fast IT

We have spent the past few years to gather the best and the brightest engineering minds focused on one simple goal:  to design an infrastructure for our customers that meets the needs of applications today and in the future. These applications require dynamic, agile, fast, secure, scalable, reliable infrastructure that is automated as a native, baseline requirement.
