ACG HotSeat Whiteboard on Nuage Networks: Seamless enterprise networking; data center to branch

Ray Mota, ACG Research, and Sunil Khandekar, CEO, Nuage Networks, discuss how the cloud is changing the way businesses consume and share information: for internal use or for sharing information with customers and business partners.The trouble with the cloud is its not ubiquitous; it is made up of distinct islands of capability. The compute resides in the data center, and the consumers reside remotely.

Nuage Networks has shown that with SDN we can remove the static constraints within and across the data center to unleash the speed of consumption of information within the cloud. We now need to provide the same seamless environment for the branch environment and to improve the dynamic nature of the wide area network.

ACG Innovation Spotlight with Rotem Salomonovitch of Nuage Networks

Paul Parker-Johnson, ACG Research, and Rotem Salomonovitch, Nuage Networks, discuss the cloud and how it is changing the way businesses consume and share information. The trouble with the cloud is its not ubiquitous; it is made up of distinct islands of capability. The compute resides in the data center, and the consumers reside remotely, in the offices and branches of corporations or at the households and on the move. In the car, on the train, at the airport (or even on the plane). These users, the consumers of the data in the cloud are mobile and that means this is a global problem.

The fabric that links the information flow across and through the cloud is based on static networking models, models that have not fundamentally changed for over 20 years; technology has evolved but the fundamental architectures have remained the same.

Nuage Networks has shown that with SDN we can remove the static constraints within and across the data center to unleash the speed of consumption of information within the cloud. We now need to provide the same seamless environment for the branch environment and to improve the dynamic nature of the wide area network.

Forecast of Residential Fixed Broadband and Subscription Video Requirements

Residential fixed broadband usage has evolved from static search and information retrieval to multimedia content delivery on a wide variety of devices. The move from broadcast service, which is multicast across the metro network, to broadband video service, which is unicast, and the use of many more devices in each household will have a massive impact on the required bandwidth capacity of the metro network.

ACG Research presents a five-year projection of average household bandwidth requirements. Average household bandwidth requirements are estimated to be 2.5 Mbps in 2014 and will grow at a five-year CAGR in a range from 19 percent to 44 percent with a most likely value of 31 percent.

Business Case for Virtual Managed Services

Cisco Evolved Services Platform provides automated, optimized, and personalized services via orchestrating virtualized network functions running on cloud data center technology. It allows fast introduction of new services and reduces the TCO of managed services sales and service delivery processes. Virtual managed services provided via ESP reduce costs and increase operational efficiency to the point where service providers can now profitably sell to smaller businesses.

ACG Research compared the total cost of ownership of the present mode of operations with the virtual managed service solution for two managed services offerings: 1) Cloud VPN service, and 2) Security service. It found that operation expenses (opex) were about 78 percent less for virtual managed service for both offers and that return on investment (ROI) for both virtual managed services offerings was more than 200 percent over a five-year planning period. The three largest sources of reduced opex are elimination of most truck rolls, many onsite maintenance and installation activities, and minimization of the costs to support onsite software.

Infinera’s Cloud Xpress: Impressive Contribution to Cloud Providers’ DCI

Growth of cloud-based services shows no real signs of slowing down. This adoption rate is propelling providers of cloud services to construct new data center capacity, work to make data centers they already have run more efficiently and improve how they network their data centers internally.

In early adoption phases of cloud, there have been two dominant uses of data center interconnection (DCI). First is for connecting enterprise data centers to service providers’ data centers for hybrid and public cloud computing services.  The second use has been to connect providers’ ecosystem partner data centers to SPs’ data centers to mash up applications and federate cloud services.

As usage has grown, though, a new set of DCI requirements has emerged. These involve connecting providers’ own data centers at very high capacities. Two scenarios dominate this trend. The first is in metro or nearby data center connections, and the second is in hyper-scale data centers deployed at great distances from other sites and running at remarkable scale.

In the first use case operators will run out of power or space in existing sites and need to create additional capacity nearby. This can be in a metro area footprint or in an extended campus. DCI is critical in these deployments because many cloud applications work in a highly distributed model. They often need access to resources in neighboring data centers many times over before responding to a single user’s request. Thus, interconnections need to be simple and fast.

In the second deployment scenario, hyper-scale operators such as Google, Facebook and Microsoft search for remote locations where land and power are less expensive and build some of the world’s largest data centers there to run their services. Server counts in these sites range from 200,000 to 500,000 or more. The need for integration with systems in the providers’ other data centers is strong in mega-site deployments as well. This leads to extremely large capacities of DCI bandwidth being deployed both locally in clustered DC locations as well as over long haul transport for sites that are a half a continent or more away.

DCI capacities required in the intra-provider configurations range from 10s of tb/s in medium-to-large scale sites to several hundred tb/s in the largest mega-center locations. Because of the ongoing growth in the use of providers’ services, the unique needs of these DCI deployments have led to the emergence of a new type of high-capacity DCI solution.

Five requirements define the new breed:
  • Efficient and flexible scaling to 100s of tb/s of transport
  • Compact, rackable form factors
  • Low power consumption
  • Simple operation
  • Programmability for integration with service automation 

Underpinnings of these requirements
A dominant aspect of cloud data centers is use of infrastructure such as servers and storage systems that are modest in unit size but able to be pooled in wide ranges of capacity to serve the needs of application or service. This leads to a bias for systems installable in compact, rackable form factors that are easy to install and expand, often leveraging auto-configuration for integration into infrastructures at very large scale.

Form factor compactness demands low power consumption. If an individual server consumes, say, 150 watts in ongoing use, a rack of 40 such servers might consume 6 kilowatts, sustained. A data center with 100,000 such servers might consume 15 megawatts (approximately estimated). It’s easy to understand why cloud providers focus on wringing every possible watt out of solutions they deploy. DCI platforms designed in a more server-like package (versus a telco office orientation) are likely to consume less power, perhaps drawing a third less power per rack than alternatives. Across 10 racks’ worth of devices, if 150-200 kilowatts of power can be saved, a solution is heading in the right direction.

A final objective that fits with the ability to pool resources goal is to support open, programmable software for DCI capacity to be dynamically provisioned according to application needs. A variety of approaches can be taken to achieve this, including plug-ins for service control software rapidly evolving for use in cloud and virtual networking infrastructures as well as API toolkits to let large cloud providers integrate with their own service management platforms. In the end, programmability to support adaptation to providers’ goals for resiliency, path allocation, and application-driven solutions are the key requirements.

This new breed of DCI solution will complement other transport solutions that implement shared network transport of various types in metro and long haul configurations. The two styles will be used by providers for different types of connections. Both will be used to support higher level service requirements for customer, partner, and internal operator data center connections.

The Cloud Xpress family introduced by Infinera is an innovative example of the kind of high capacity, small form factor, programmable DCI platform cloud operators are leaning toward for their internal DCI deployments. Cloud Xpress is initially targeted for metro deployments. Leveraging optical innovations Infinera has previously introduced and engineering them into a platform capable of 20+ tb/s in a single rack, Cloud Xpress is an impressive contribution to the state of the DCI art. If trials prove out successfully, Cloud Xpress has every prospect of helping cloud operators scale out their data center deployments and interconnect them with the capacity and elasticity they desire.

Metacloud Adds Versatility and Strength to Cisco’s InterCloud

Among the best promises of the cloud are flexibility in workload deployment and efficient, scalable orchestration of deployments regardless of location or underlying infrastructure. 

Cisco’s acquisition of Metacloud for integration into its InterCloud portfolio is an important step toward the InterCloud realizing these promises. Metacloud adds versatility and strength to the InterCloud service offering in at least three ways:

1. Metacloud’s innovative OpenStack as a Service solution allows businesses to deploy private clouds using OpenStack software without needing to invest in developing in-house OpenStack expertise (because their cloud is managed by Metacloud as a service).  This is a very powerful way to open up use of OpenStack software in business private clouds for companies that have not been ready to make that commitment to date. Although OpenStack is very appealing as a service delivery environment because of its rich open source community of technical contributors, it is still relatively young in terms of delivery packaging and integration options for adopters who do not have the resources to develop that expertise. Making the OpenStack environment available on an efficiently managed basis by Metacloud as the manager takes the sting out of adopting OpenStack for many businesses and allows them to concentrate fully on implementing the applications they’re interested in on a powerful open software base.

2. OpenStack as a Service, now from the InterCloud, can be deployed on top of infrastructures other than Cisco’s, in addition to being deployable on Cisco infrastructure systems (such as UCS and Nexus). This opens up access to the InterCloud ecosystem for customers without having to meet the criterion of running on Cisco underlying hardware in every case. In its truest sense, that is a crucial criterion for a serious cloud computing framework to meet: by being able to instantiate virtual compute, network, storage, and related applications in a truly open software environment without regard to specific underlying hardware implementations (other than that they integrate successfully into the OpenStack software framework) the flexibility of adoption paths available to customers for engaging with the InterCloud ecosystem of operators and application suppliers is multiplied by an order of magnitude. It doesn’t prevent the use of parallel ACI-based Cisco infrastructure systems. Rather, it opens up the option of using additional infrastructure environments quickly and efficiently by introducing the managed OpenStack as a Service framework.

3. By bringing a managed OpenStack solution to its InterCloud portfolio in support of private clouds, Cisco is laying the groundwork for extending the InterCloud’s services based on OpenStack to include hybrid and public services leveraging the OpenStack technology base. Making this additional implementation option available to end customers significantly enhances the versatility and appeal of the ecosystem it is developing. 

Time will tell how seamless and robust the OpenStack additions to the InterCloud portfolio will be. Customers will decide. However, if one were looking for signs that the InterCloud fabric might have the versatility and flexibility in deployment options the cloud computing community so highly values, the Metacloud acquisition would appear to be a compelling signal heading in that direction.
