Citrix and NetScaler 1000V Taking Cisco Cloud Network Services to the Next Level


CiscoCitrixWith Cisco Live! in Orlando on the horizon, we are kicking off the news cycles and technology innovation a little early.  Today we’re teaming with our friends at Citrix to announce the expansion of our virtual networking portfolio and provide clarity around our strategy for application delivery controller solutions.

There are two key elements of this strategy:

First, Cisco will begin reselling and supporting a customized version of the popular Citrix NetScaler virtual application delivery controller (ADC) as part of our Cloud Network Services portfolio. Branded Citrix NetScaler 1000V, the Cisco version of the product will be fully supported by the Cisco Technical Assistance Center.  We will begin selling the NetScaler 1000V when available in Q3 CY 2013.

Secondly, Cisco and Citrix have worked on joint development to tightly couple the NetScaler ADC into Cisco’s virtual networking framework.  This joint development includes integration of NetScaler 1000V with the Cisco Nexus 1100 Cloud Services Platform, and the Nexus 1000V services integration technology, vPath.

Cisco’s Cloud Network Services strategy bridges IT to application architects, and with this Citrix NetScaler 1000V announcement, we integrate virtual applications to Cisco Unified Fabric, delivering scalable, reliable application services to users.

Why is NetScaler 1000V the right solution now?

Advances in cloud computing, data center consolidation, mobility and big data are imposing new demands on the network, along with a drive for greater network simplification and automation.

As virtual networking and programmable overlay networks evolve to meet these challenges, an equal evolution needs to take place in Layer 4-7 application networking services and security to support widespread virtualization, application mobility, cloud architectures and network orchestration.

Cisco’s solution to this challenge is Cloud Network Services, a portfolio of integrated, application-aware network services and security offerings designed for virtual and cloud environments. The Cloud Network Services framework eliminates the obstacles of physical service appliances to accommodate the requirements of virtual applications and cloud deployments, such as:

  • Limited scalability of physical services in fixed locations
  • Inconsistent application performance based on workload location relative to services
  • Difficulty in inserting security and network services into virtual networks
  • Lack of control over services and policies for applications deployed at cloud service providers


The NetScaler 1000V virtual ADC

NetScaler 1000V fills an important void in Cisco’s virtual product architecture for an application delivery controller solution to give applications critical performance enhancements, offload application servers, and to help guarantee quality of service and improve end user experience. These requirements are growing exponentially with the increases in bring-your-own-device (BYOD), client mobility, and cloud migration.

Virtual services can be more flexibly deployed to cloud service providers without modification, while relying on the same infrastructure and policies that they might have with corresponding physical appliances in their on-premises data centers. With NetScaler 1000V, customers can have consistency across their physical, virtual and cloud infrastructures, along with the Citrix NetScaler physical appliances.

The Cisco Cloud Services Platform

With the evolution to Cloud Network Services as the Layer 4-7 framework for virtual and cloud networks, organizations are increasingly looking for a flexible platform to deploy these virtual service nodes rather than use existing application servers. Cisco has created the Nexus 1100 Cloud Services Platform to address this need.

The Nexus 1100 Cloud Services Platform is a series of UCS-based appliances dedicated to running Cloud Network Service nodes. In addition to the virtual services listed above, the Nexus 1100 runs the management platforms for the virtual network, the Virtual Security Module (VSM), and the Data Center Network Manager (DCNM) application. The Cloud Services Platform can be dynamically configured to allocate its virtual CPUs to each service as needed based on current application and performance requirements. Current models of the Nexus 1100 series include the Nexus 1110-S and 1110-X.

vPath: The Secret Sauce to Enabling Services in Virtual and Cloud Networks

vPath is a component of the Cisco Nexus 1000V virtual switch which directs traffic to appropriate virtual service nodes, such as firewalls or ADCs, in the right order for each application, independent of the topology of the network or the location of the network services. This allows for greater application mobility and more reliable service delivery. NetScaler 1000V will be integrated into the Cloud Network Services framework via vPath and will be a key differentiator against other ADC products.

As part of the Cisco-Citrix collaboration in next generation data center and cloud architectures, the Citrix NetScaler MPX line of high performing application delivery controllers will also attach to the Cisco Nexus 7000 Series switches.  This capability will provide customers the benefits of higher resiliency, plug and play installation, improved agility, and increased leverage of both their switching and ADC investments.

All of the Cisco Cloud Network Services, including the Citrix NetScaler 1000V, will be on display next week at Cisco Live! Along with other announcements we have planned for data center and cloud networking, it promises to be a great event and we hope to see you there.

Don’t Take Your Eyes off VDI – We’re Certainly Not!

This blog post promises to avoid telling you about all the fantabulous (I know that’s not a woUCSrd) growth expected in the number of hosted virtual desktops to be deployed by 2016.  What I do want to share, is how Cisco is ramping up our investments in accelerating your path to virtual desktop success, and how we’re tapping into the fundamentals of our Unified Computing System (UCS) to deliver new VDI efficiencies; the same efficiencies that have made Cisco the 2nd most preferred x86  blade server vendor* worldwide, in just 4 years!  So why are so many organizations moving away from their legacy compute solution, and choosing UCS for VDI workloads and more?

Differentiated capabilities that address VDI pain points: TCO and Manageability

It’s no secret to anyone that VDI is not simple to deploy.  You essentially have to bring together multiple seemingly disparate solution elements (server, storage, virtualization, broker, network, security, etc.) and make them work in a cohesive manner, and then be certain that your implementation will scale from a small pilot of 50 users to hundreds, thousands, or more!  Clearly with such complexity, the last thing you need is a complex compute infrastructure underneath it all.  There are 3 key things at the heart of this, that speak to why UCS is better for VDI:on-board

1.)    Server-resident flash.  Our “On-Board” Architecture for VDI intercepts the rapidly proliferating use of flash based storage solutions that offer expansive IOPS capacity and huge performance.  UCS takes it a step further by offering an integrated solution leveraging our partner Fusion-io.  We’ve additionally delivered reference architectures that extend the use cases and attractiveness of flash-based solutions with appliance approaches (that direct-connect the storage array to our fabric interconnect) as well as more traditional multi-tiered architectures.  More on that in a moment…

service profile2.)    We’ve made it easier to provision and manage the hosts for your virtual desktop deployments.  UCS Service Profile Templates enable rapid deployment from bare metal, creating a zero-touch, mistake-proof, stateless operations model.  Now, when you add the On-Board, server-resident flash to the configuration, you extend the reach of this management model to include high-performance, economical storage, completely provisioned and managed as part of the blade configuration/profile!  No SAN or associated expertise required!  Perfect for floating, non-persistent desktops.VIC

3.)    Granular visibility across the virtualized infrastructure.  With user desktops now running amidst other mission-critical workloads in the data center, there’s more reason than ever to ensure that you can impart QoS, security and manageability across the multitude of virtual machine traffic flows traversing the data center.  Cisco Virtual Machine Fabric Extender (VM-FEX) and Cisco Nexus 1000v provide the visibility and controls that make this possible, extending physical world policy and administration to virtual.

Wristwatches, Bicycle Helmets, and VDI…

A long time ago, it used to be comforting, to hear the words “One Size Fits All”.  As though our interests were surely represented within that catch-all, assuring us that we weren’t going to get left out in the rain.  You could safely make that impulse-driven purchase, bring it home (or have it delivered), and know with certainty, that you wouldn’t be disappointed.  It’s almost laughable to think that we subscribed to this way of thinking for about 50 years.  But thankfully, we live, work and play in a world where it’s not about one-size-fits-all, and the only things we’ll accept as such, are wristwatches, and bicycle helmets! (unless you have a gargantuan sized cranium)

And so it is with your IT environment – “One-Size-Fits-All” feels too much like hand-cuffs (which coincidentally are also one-size-fits-all).  We’ve done away with the notion that a solution that’s optimized for a Fortune 500, is going to be at all suitable for a medium-sized business with almost 1,000 employees.  While both organizations might have a strategic imperative around workspace mobility, and have set out to virtualize the desktops of say, 5% of their workforce, they’ll approach this problem in two completely different ways.

  • One of these organizations will have an extensive , multi-tiered networking and security infrastructure, optimized for virtual machine traffic, the other may not.
  • One of these organizations will have a mature SAN infrastructure in place, with embedded resources and expertise, and lots of existing mission-critical data already housed there.  The other may not.
  • One of these organizations will have a high percentage of virtualized workloads and a highly automated/orchestrated environment for rapidly spinning up new infrastructure.  The other may not.

Carchpicertainly these two environments are not going to take the same solution approach to deploying virtual desktops?  They will however, share many of the same key objectives/demands: future proof scalability, resiliency, streamlined provisioning and operations, consistent user experience for the 1st user as well as the 1000th.  And they’ll want all of this with the lowest possible TCO.


Last month, Cisco introduced our expanwebcastded suite of solution architectures for desktop virtualization.  This portfolio was struck with the objective of ensuring our customers would never have to settle for a One-Size-Fits-All approach to deploying VDI, recognizing that they’re deploying this solution from a multitude of possible starting points in their IT maturity.  With four new solution architectures, each built on Cisco Unified Computing System (UCS), and each backed by design guides and reference configurations co-developed with industry-leading partners in storage and storage-optimization technologies, we’ve taken the risk and guesswork out of choosing the deployment methodology that’s right-sized for your organization.  Check out my friend Ashok’s more detailed post on the new reference architecture portfolio.

OpenDaylight: Building an Open Source Community around SDN

It’s great to see Cisco and many companies across the industry make a major change in the use of Open Source via the newly form project hosted by the Linux Foundation called OpenDaylight. This consortium is an industry-wide, open and transparent effort to catalyze innovation and accelerate an application ecosystem for software-defined networking. With all the partners involved we are working to not only further development and adoption of SDN but also to foster a new developer community. A consortium like this has been long overdue and it’s great to finally see it come to fruition.

We are incredibly pleased to partner with Arista, Big Switch Networks, Brocade, Citrix, Dell, Ericsson, Fujitsu, HP, IBM, Intel, Juniper Networks, Microsoft, NEC, Nuage Networks, PLUMgrid, RedHat and VMware on the Project. This is the largest effort to date to drive Software-Defined Networking across the industry and into new markets.  While the initial goal is to build a common, industry backed SDN Platform, the broader objective is to give rise to an entire ecosystem of developers that can freely utilize the code, contribute to the project and commercialize the offerings. I further expect the ecosystem to expand into areas like tools and services.

Cisco has donated our core “Cisco ONE” controller code to the project and has officially open sourced the code under the Eclipse Public License. The community has come together around this code to form the architecture (see below) for the Open SDN Framework. Beyond donations of code, Project members are supporting the project via both financial investment and via developers we are committing to work full-time on the project overall. Donations from other members of the Project can be seen here and we expect this list to only grow.

As Open Source increasingly becomes a standard for customers and developers, we look at this as a new way to meet our customer needs and also help developers innovate in new ways without the barriers of vendor lock-in. Open Source is increasingly important for our customers and developers as well and as they evolve, we evolve. Cisco to date has supported Open Source through efforts such as OpenStack and now OpenDaylight and we look at Open Source as a critical pillar in our software strategy moving forward. By allowing developers to freely use these solutions we hope to enable a new developer ecosystem for software-defined networking and more. We are fully committed to enabling developers, both current and new, to deliver innovating applications and services that will help customers across the board realize the value of SDN faster than before.

The OpenDaylight architecture and code offering to date includes a modular southbound plugin architecture for multi-vendor environments. In addition, OpenDaylight offers an extensible northbound framework with both Java & REST APIs to ensure multiple developer skill-sets can build applications to the platform. We are also planning to build a onePK plugin for OpenDaylight to enable multiple users to drive network intelligence into their SDN applications. As you can see from below we will also be supporting key standards with this effort, including OpenFlow.




It’s important to note that you don’t launch a community; you build one. By investing in OpenDaylight we hope that our customers, partners and developers across multiple industries will now have the ability to build applications that frankly make the network easier to use and more automated. As an industry we are moving in a new direction and further up the stack and OpenDaylight offers new opportunities for application creation and monetization beyond the networking layer.

It’s a true rarity when you see both partners and competitors come together for the good of the community, and contribute code for the universal good of the customer. All OpenDaylight participants have committed to open source guidelines that include open communication, ethical and honest behavior, code and roadmap transparency and more. An Open Source project is only as successful as the community of developers and the level of code quality, and OpenDaylight’s Board of Directors (which includes multiple parties cross-industry) will be ensuring that partners, code contributors and project committers all abide by the same guidelines for the success of the project over the success of their own company’s offerings.

For more information, please see Code will be available for download soon, and we are looking for interested individuals for commitments across the board – from technical offerings to application development, and we welcome contributions from both individuals and other organizations. All ideas are welcome, and we look forward to multiple new innovative solutions coming from this.

Congratulations to all our partners and individuals who helped to make this happen, including the hard work done by the Linux Foundation. It’s truly an amazing accomplishment and we expect to see much more in the near future.
