Organizations are migrating to the cloud because it dramatically reduces IT costs as we make much more efficient use of resources (either ours or by leveraging some cloud provider’s resources at optimal times). When done right, cloud also increases business agility because applications and new capacity can be spun up quickly on demand (on-premises or off), network and services configurations can be updated automatically to suit the changing needs of the applications, and, with enough bacon, unicorns can fly and the IT staff can get home at a reasonable hour.
Whenever you ask a CIO-type at any of these organizations what’s holding them back from all this cloud goodness, though, more often than not the answer has something to do with security: “Don’t trust the cloud…”, “Don’t trust the other guy in the cloud…”, “Cloud’s not compliant…”. You have to be something of a control freak to be a CIO/CISO these days, and, well, isn’t “cloud” all about giving up some control, after all (in return for efficiency and agility)?
Even if you overcome your control issues and you find a cloud you can trust (even if it’s your own private cloud – we can take baby steps here…), if we are going to achieve our instant on-demand application deployment, network provisioning and cost-efficient workload placement process, it turns out all the security stuff can throw another obstacle in our way. Cloud security isn’t like old-fashioned data center security where you could just put a huge firewall in front of the data center and call it good. For secure multi-tenancy and a secure cloud overall, virtually every workload (or “every virtual workload”?) needs to be secured from every other (except for the exceptions we want to make). Some folks call this “microsegmentation”, a fancy word for an old concept, but, a fundamental requirement that cloud deployments need to address. (Spoiler alert: ACI does this very well.) Read More »

It’s an exciting time in to be in our industry, especially as we witness how technology continues to reshape how we connect and communicate through a myriad of applications and devices not only within our own companies, but also with our customers and partners.
At the epicenter of this technological transformation, we continue to find that the network is what ultimately enables these applications and their users to connect. We also quickly find that if this same network is not ready to deal with the ever increasing influx of devices, new applications with varying traffic patterns, and 24 x 7 access from pretty much anywhere, it can quickly turn into an IT departments nightmare.
It is exactly to deal with these new types of requirements that the award-winning Nexus 9000 Series (made up of both the Nexus 9500 and Nexus 9300 portfolios) was introduced into the market almost 11 months ago. Now, over 600 customers have purchased this new switching family and are experiencing the positive impact that having a high performing, scalable, programmable, and resilient data center network has on application performance and overall user quality of experience in both traditional and Application Centric Infrastructure (ACI) architectures.
Today we are happy to announce the addition of three new switches into the Nexus 9300 Series as well as a 6-port 40Gbps module to deliver more flexibility and form factor options to meet different architectural needs. The new products are:
- Cisco Nexus 9372TX: 1-rack-unit switch supporting 1.44 Tbps of bandwidth across 48 fixed 1/10-Gbps BASE-T ports and 6 fixed 40-Gbps QSFP+ ports
- Cisco Nexus 9372PX: 1-rack-unit switch supporting 1.44 Tbps of bandwidth across 48 fixed 1/10-Gbps SFP+ ports and 6 fixed 40-Gbps QSFP+ ports
- Cisco Nexus 9332PQ: 1-rack-unit switch supporting 2.56 Tbps of bandwidth across 32 x 40Gbps QSFP+ ports
- 6-port 40 Gigabit Ethernet Module for the Nexus 93128TX, 9396TX , and 9396PX for connectivity options to meet your needs
These new switches deliver high performance, additional buffers, as well as support for VXLAN routing in a compact form factor. In addition to this, support for the Cisco Nexus 2000 Fabric Extenders has also been added to the Nexus 9300 portfolio. So if you already had Fabric Extenders in your data center or are looking for a scalable and operationally simplified architecture – you can now have the best of both worlds.
But it doesn’t end there – in case you missed it, Cisco recently announced the availability of the Application Policy Infrastructure Controller (APIC) making the creation of a more simplified, robust, application-centric infrastructure a reality with the Nexus 9000 Series as the network foundation. You can read more about it here – in Craig Huitema’s blog, which outlines not only new products on the nexus 9000 series including 100Gbps on the Nexus 9500, but also how we have simplified the introduction of the Nexus 9000 and ACI into data centers through different ACI starter kits and bundles. In addition, for those of you that want to deploy the Nexus 7000 in combination with the Nexus 9300s, new bundles that bring together the Nexus 7000 and Nexus 9300 are also available.
As you can see, we continue to deliver the products and architectural options that will allow data centers of all sizes to address increasing and changing application requirements. Between the Nexus 9300 and Nexus 9500 portfolios and their ability to be deployed into 3-tier, spine/leaf, or ACI architectures, customers can benefit from more connectivity options and a diverse set of form factors to meet varying data center needs. I invite you to learn more about the Nexus 9000 Series at www.cisco.com/go/nexus9000.

At the June Hadoop Summit in San Jose, Hadoop was re-affirmed as the data center “killer app,” riding an avalanche of Enterprise Data, which is growing 50x annually through 2020. According to IDC, the Big Data market itself growing six times faster than the rest of IT. Every major tech company, old and new, is now driving Hadoop innovation, including Google, Yahoo, Facebook Microsoft, IBM, Intel and EMC – building value added solutions on open source contributions by Hortonworks, Cloudera and MAPR. Cisco’s surprisingly broad portfolio will be showcased at Strataconf in New York on Oct. 15 and at our October 21st executive webcast. In this third of a blog series, we preview the power of Application Centric Infrastructure for the emerging Hadoop eco-system.
Why Big Data?
Organizations of all sizes are gaining insight and creativity into use cases that leverage their own business data.
The use cases grow quickly as businesses realize their “ability to integrate all of the different sources of data and shape it in a way that allows business leaders to make informed decisions.” Hadoop enables customers to gain insight from both structure and unstructured data. Data Types and sources can include 1) Business Applications – OLTP, ERP, CRM systems, 2) Documents and emails 3) Web logs, 4) Social networks, 5) Machine/sensor generated, 6) Geo location data.
IT operational challenges
Even modest-sized jobs require clusters of 100 server nodes or more for seasonal business needs. While, Hadoop is designed for scale out of commodity hardware, most IT organizations face the challenge of extreme demand variations in bare-metal workloads (non-virtualizable). Furthermore, they are requested by multiple Lines of Business (LOB), with increasing urgency and frequency. Ultimately, 80% of the costs of managing Big Data workloads will be OpEx. How do IT organizations quickly, finish jobs and re-deploy resources? How do they improve utilization? How do they maintain security and isolation of data in a shared production infrastructure?
And with the release of Hadoop 2.0 almost a year ago, cluster sizes are growing due to:
- Expanding data sources and use-cases
- A mixture of different workload types on the same infrastructure
- A variety of analytics processes
In Hadoop 1.x, compute performance was paramount. But in Hadoop 2.x, network capabilities will be the focus, due to larger clusters, more data types, more processes and mixed workloads. (see Fig. 1)
ACI powers Hadoop 2.x
Cisco’s Application Centric Infrastructure is a new operational model enabling Fast IT. ACI provides a common policy-based programming approach across the entire ACI-ready infrastructure, beginning with the network and extending to all its connected end points. This drastically reduces cost and complexity for Hadoop 2.0. ACI uses Application Policy to:
– Dynamically optimize cluster performance in the network
– Redeploy resources automatically for new workloads for improved utilization
– Ensure isolation of users and data as resources are deployments change
Let’s review each of these in order:
Cluster Network Performance: It’s crucial to improve traffic latency and throughput across the network, not just within each server.
- Hadoop copies and distributes data across servers to maximize reliability on commodity hardware.
- The large collection of processes in Hadoop 2.0 are usually spread across different racks.
- Mixed workloads in Hadoop 2.0, support interactive and real-time jobs, resulting in the use of more on-board memory and different payload sizes.
As a result, server IO bandwidth is increasing which will place loads on 10 gigabit networks. ACI policy works with deep telemetry embedded in each Nexus 9000 leaf switch to monitor and adapt to network conditions.
Using policy, ACI can dynamically 1) load-balance Big Data flows across racks on alternate paths and 2) prioritize small data flows ahead of large flows (which use the network much less frequently but use up Bandwidth and Buffer). Both of these can dramatically reducing network congestion. In lab tests, we are seeing flow completion nearly an order of magnitude faster (for some mixed workloads) than without these policies enabled. ACI can also estimate and prioritize job completion. This will be important as Big Data workloads become pervasive across the Enterprise. For a complete discussion of ACI’s performance impact, please see a detailed presentation by Samuel Kommu, chief engineer at Cisco for optimizing Big Data workloads.
Resource Utilization: In general, the bigger the cluster, the faster the completion time. But since Big Data jobs are initially infrequent, CIOs must balance responsiveness against utilization. It is simply impractical for many mid-sized companies to dedicate large clusters for the occasional surge in Big Data demand. ACI enables organizations to quickly redeploy cluster resources from Hadoop to other sporadic workloads (such as CRM, Ecommerce, ERP and Inventory) and back. For example, the same resources could run Hadoop jobs nightly or weekly when other demands are lighter. Resources can be bare-metal or virtual depending on workload needs. (see Figure 2)
How does this work? ACI uses application policy profiles to programmatically re-provision the infrastructure. IT can use a different profile to describe different application’s needs including the Hadoop eco-system. The profile contains application’s network policies, which are used by the Application Policy Infrastructure controller in to a complete network topology. The same profile contains compute and storage policies used by other tools, such as Cisco UCS Director, to provisioning compute and storage.
Data Isolation and Security: In a mature Big Data environment, Hadoop processing can occur between many data sources and clients. Data is most vulnerable during job transitions or re-deployment to other applications. Multiple corporate data bases and users need to be correctly to ensure compliance. A patch work of security software such as perimeter security is error prone, static and consumes administrative resources.
In contrast, ACI can automatically isolate the entire data path through a programmable fabric according to pre-defined policies. Access policies for data vaults can be preserved throughout the network when the data is in motion. This can be accomplished even in a shared production infrastructure across physical and virtual end points.
As organizations of all sizes discover ways to use Big Data for business insights, their infrastructure must become far more performant, adaptable and secure. Investments in fabric, compute and storage must be leveraged across, multiple Big Data processes and other business applications with agility and operational simplicity.
Leading the growth of Big Data, the Hadoop 2.x eco-system will place particular stresses on data center fabrics. New mixed workloads are already using 10 Gigabit capacity in larger clusters and will soon demand 40 Gigabit fabrics. Network traffic needs continuous optimization to improve completion times. End to end data paths must use consistent security policies between multiple data sources and clients. And the sharp surges in bare-metal workloads will demand much more agile ways to swap workloads and improve utilization.
Cisco’s Application Centric Infrastructure leverages a new operational and consumption model for Big Data resources. It dynamically translates existing policies for applications, data and clients in to fully provisioned networks, compute and storage. . Working with Nexus 9000 telemetry, ACI can continuously optimize traffic paths and enforce policies consistently as workloads change. The solution provides a seamless transition to the new demands of Big Data.

Today’s Cisco announcements illustrate the momentum we’ve seen thus far for Cisco’s approach to cloud. Partners across the globe are very eager to engage and understand what roles they can play to help them meet their customer’s needs for choice, flexibility, security, and compliance. As more clouds connect, opportunities for our partners to extend value and become more relevant with their customers increase.
Cisco’s approach has always been partner-centric. And with Intercloud, partners have even more opportunities to be cloud builders, providers, resellers, consultants, Independent Software Vendors (ISV) and more. The foundation for Cisco’s Intercloud is built on:
- A hybrid cloud model to place and move Virtual Machine (VM) workloads on any cloud
- Application-centric policy control for Chief Information Officers across all IT components and clouds at scale
- Data virtualization at scale, to address the Internet of Everything (IoE) explosion, and
- A network-centric partner ecosystem that provides the most choice and data sovereignty over a vendor direct model
While partner business models vary, I always emphasize that there are many opportunities and multiple roles for Intercloud partners. Intercloud partners will bring important value to the ecosystem with professional services, new offers, Service Level Agreements (SLA), consumption pricing, consolidated billing and much more. They can also enhance their roles and monetize in other ways. For example, Intercloud partners can build and operate private clouds with professional services, which opens up opportunities to create a profitable hybrid IT business model. Read More »

Big Data is not just about gathering tons of data, the digital exhaust from the internet, social media, and customer records. The real value is in being able to analyze the data to gain a desired business outcome.
Those of us who follow the Big Data market closely never lack for something new to talk about. There is always a story about how a business is using Big Data in a different way or about some new breakthrough that has been achieved in the expansive big data ecosystem. The good news for all of us is, we have clearly only scratched the surface of the Big Data opportunity!
With the increasing momentum of the Internet of Everything (IoE) market transition, there will be 50 billion devices connected to the Internet by 2020—just five years from now. As billions of new people, processes, and things become connected, each connection will become a source of potentially powerful data to businesses and the public sector. Organizations who can unlock the intelligence in this data can create new sources of competitive advantage, not just from more data but from better access to better data.
What we haven’t heard about – yet—are examples of enterprises that are applying the power of this data pervasively in their organizations: giving them a competitive edge in marketing, supply chain, manufacturing, human resources, customer support, and many more departments. The enterprise that can apply the power of Big Data throughout their organization can create multiple and simultaneous sources of ongoing innovation—each one a constantly renewable or perpetual competitive edge. Looking forward, the companies that can accomplish this will be the ones setting the pace for the competition to follow.
Cisco has been working on making this vision of pervasive use of Big Data within enterprises a reality. We’d like to share this vision with you in an upcoming blog series and executive Webcast entitled, ‘Unlock Your Competitive Edge with Cisco Big Data Solutions’, that will air on October 21st at 9:00 AM PT.
I have the honor of kicking off the multi-part blog series today. Each blog will focus on a specific Cisco solution our customers can utilize to unlock the power of their big data – enterprise-wide– to deliver a competitive edge to our customers. I’m going to start the discussion by highlighting the infrastructure implications for Big Data in the internet of Everything (IoE) era and focus on Cisco Unified Computing System initially.
Enterprises who want to make strategic use of data throughout their organizations will need to take advantage of the power of all types of data. As IoE increasingly takes root, organizations will be able to access data from virtually anywhere in their value chain. No longer restricted to small sets of structured, historical data, they’ll have more comprehensive and even real-time data including video surveillance information, social media output, and sensor data that allow them to monitor behavior, performance, and preferences. These are just a few examples, but they underscore the fact that not all data is created equally. Real-time data coming in from a sensor may only be valuable for minutes, or even seconds – so it is critical to be able to act on that intelligence as quickly as possible. From an infrastructure standpoint, that means enterprises must be able to connect the computing resource as closely as possible to the many sources and users of data. At the same time, historical data will also continue to be critical to Big Data analytics.
Cisco encourages our customers to take a long-term view—and select a Big Data infrastructure that is distributed, and designed for high scalability, management automation, outstanding performance, low TCO, and the comprehensive, security approach needed for the IoE era. And that infrastructure must be open—because there is tremendous innovation going on in this industry, and enterprises will want to be able to take full advantage of it.
One of the foundational elements of our Big Data infrastructure is the Cisco Unified Computing System (UCS). UCS integrated infrastructure uniquely combines server, network and storage access and has recently claimed the #1, x86 blade server market share position in the Americas. It’s this same innovation that propelled us to the leading blade market share position that we are directly applying to Big Data workloads. With its highly efficient infrastructure, UCS lets enterprises manage up to 10,000 UCS servers as if they were a single pool of resources, so they can support the largest data clusters.
Because enterprises will ultimately need to be able to capture intelligence from both data at rest in the data center and data at the edge of the network, Cisco’s broad portfolio of UCS systems gives our customers the flexibility to process data where it makes the most sense. For instance, our UCS 240 rack system has been extremely popular for Hadoop-based Big Data deployments at the data center core. And Cisco’s recently introduced UCS Mini is designed to process data at the edge of the network.
Because the entire UCS portfolio utilizes the same unified architecture, enterprises can choose the right compute configuration for the workload, with the advantage of being able to use the same powerful management and orchestration tools to speed deployment, maximize availability, and significantly lower your operating expenses. Being able to leverage UCS Manager and Service Profiles, Unified Fabric and SingleConnect Technology, our Virtual interface card technology, and industry leading performance really set Cisco apart from our competition.
So, please consider this just an introduction to the first component of Cisco’s “bigger”, big data story. To hear more, please make plans to attend our upcoming webcast entitled, ‘Unlock Your Competitive Edge With Cisco Big Data Solutions’ on October 21st.
Every Tuesday and Thursday from now until October 21st, we’ll post another blog in the series to provide you with additional details of Cisco’s full line of products, solutions and services.
