The Enterprise Goal
Enterprises are continually striving to reduce their IT costs and optimize utilization of their compute resources. The demand for compute, storage and networking resources to support business applications can be difficult to predict, leading to risks of overbuilding or underestimation of demand. As a result Enterprises are looking to adopt cloud services that are available on-demand, and are flexible and scalable to meet their IT service needs in a predictable and cost effective manner.
The Service Provider Advantage
Communications service providers are in a unique position to meet the needs of the Enterprise for service assurance as they develop cloud services. With considerable experience in managing data centers, and with an IP NGN MPLS network spanning from their data centers to enterprise locations around the globe, as well as having back office systems, including billing and support, communications service providers have what it takes for success in the cloud services market. Given the critical role of both the data center and the network in application delivery the development of cloud-based services represents an opportunity for the communications service provider to work with the enterprise to help them overcome their challenges for delivery of business critical applications throughout the organization, while meeting their business goals to contain costs, protect data assets, and ensure employee productivity.
Leverage The Network
Too meet these challenges and deliver reliable cloud-services communications service providers can leverage their IP NGN MPLS network and data center assets and apply their considerable expertise and experience to deliver service level agreements that align with the business processes of the enterprise, so that the enterprise can adopt cloud services with confidence, knowing that their applications will have the performance and security that they need as they are delivered over the WAN.

Enabling the Network Service Layer for Virtualized and Cloud Infrastructure
The Need for Virtualization
In their quest to reduce administrative and hardware costs and to increase the availability of server resources IT administrators are embracing server virtualization to the point that it has become a fundamental data center technology. Server virtualization makes it possible for IT administrators to move virtual server instances, and the applications that run on them, from one physical machine to another as needed, and have to them running at the new location within moments. This mobility allows IT administrators to optimize server utilization or to take advantage of idle compute resources as well as to recover from server failures almost instantly.
Workload Availability
The mobility of virtual servers is what makes server virtualization so appealing. This mobility not only enables movement of virtual machines from one server to another within the same data center, it also enables movement of virtual machines from one data center to another. Mobility of virtual machines between data centers is critical as it enables IT administrators to make use of available resources in another data center and to recover from data center outages, maintaining availability to applications and business services seamlessly.
The Network Can Help
In the data center application performance, availability and security is enhanced by a number of network services such as server load balancing, WAN Optimization and firewalls, which have been delivered by physical appliances. As IT administrators take advantage of the benefits of server mobility that is enabled by server virtualization they seek to have the same mobility available in the network services that benefit those virtual servers and their applications. While it’s possible to have the same network services appliances running in all data centers the challenge is with configuring them to recognize the specific virtual server instances that have been moved between data centers.

The Critical Role of the Network in Supporting Cloud-Based Solutions
Cloud Services
The Cloud-based service model offers the Enterprise access to a rich range of services and applications without the overhead of having to deploy and manage the underlying infrastructure. This results in much lower costs for access to services and applications. This is especially true for one time or periodic workloads where resources may sit idle for months until required. As a result Enterprises are increasingly embracing cloud services and benefiting from on-demand availability.
Delivery Models
Demand for cloud services is being met in a number of ways. Independent software vendors offer services from their data center over the Internet, such as Salesforce.com’s CRM application. Some ISVs leverage an IaaS provider such as Amazon to host their application on the Internet such as Adobe’s LiveCycle Enterprise Suite. However, since these approaches rely on the Internet it is not possible to provide end-to-end quality of service (QoS), so neither approach supports providing an SLA for network performance. This is increasingly a concern for Enterprise customers.
The Need for SLA's
The need for SLA’s for cloud services opens up an opportunity for communications service providers (CSPs) to offer a wide range of network centric solutions that are supported by an SLA. CSPs are in a unique position to offer these solutions because, unlike the Internet, the Next Generation Networks (NGNs) that CSPs have deployed, based on IP and MPLS, are capable of providing contracted levels of availability, delay, jitter and packet loss. As a result CSPs can provide cloud-based solutions with SLAs by providing these solutions to customers from their own data center and over their NGN.

Unified Network Services for Cloud Service Providers
Services from the Cloud
Services from the cloud offer cost and efficiency benefits to businesses, but until now many customers have been hesitant to buy cloud services, especially for mission-critical business applications, because of concerns about security, performance, and availability. Cloud service providers need to address these concerns by offering network services for applications hosted in the cloud. Cloud service providers can use their data center and IP NGN assets to deliver these services, however, they need a new service delivery model offering the scalability, flexibility, and multi-tenant capabilities needed for cloud service delivery. Delivering cloud services requires efficiency and agility in the data center where applications are hosted. To support on-demand delivery of cloud services, network and computing infrastructures need to be virtualization aware, especially for services that increase the availability and performance of applications.
The Cisco Solution
To meet this need Cisco is delivering virtualized versions of network services appliances as a part of our network services solution. The Cisco® Unified Network Services (UNS) solution presents a new opportunity for cloud service providers to offer security and performance services as well as reporting and monitoring for virtualized applications and other infrastructure services such as BC/DR, VDI or Hosted Communications.

Optimizing Windows 7 Desktop Delivery over WAN using Cisco WAAS
As the migration to Windows 7 as the desktop operating system picks up, IT organizations are looking at hosting desktops in the data center using Virtual Desktop Infrastructure (VDI) as the desktop delivery method. We are finding that this is especially popular in the finance, healthcare, and federal verticals where security and compliance makes VDI an attractive choice. Moreover, IT managers in other vertical industries are interested in this technology as a flexible option to serve their employees while assisting with their desktop management goals.One of the ongoing dilemmas for IT continues to be ensuring a good user experience for any new method used for delivering applications to end users. Many users are in remote branch offices, campus locations, or are mobile; as a result these users are separated from the data center by the Wide Area Network (WAN). Limited bandwidth (per user) on the WAN pipes, high WAN latencies, packet loss, and more often a combination of all three, impacts the user experience significantly. This is where the Cisco WAN optimization solution (Cisco WAAS) can assist IT with delivering a rich Windows 7 user experience to remote users while reducing the need for bandwidth upgrades.
If one looks at the usage profile, users are typically using productivity applications (eg: email, web, document preparation, presentations, etc), and accessing corporate videos for training as well as printing documents. These users are accustomed to getting a rich experience using applications locally on their Windows 7 desktops. The goal of the Cisco WAAS solution is to maintain this rich experience when the desktop moves to the data center, and is delivered using a VDI delivery protocol such as Microsoft RDP over the WAN.

Virtual WAN Optimization: Enabling Application Migration to the Cloud
A growing trend in networking is the migration of applications to the cloud as organizations look to take advantage of deployment flexibility and lower management costs. This was the theme at VMWorld in San Francisco recently, where Cisco had major presence, and presented on our capabilities in the network that enable virtualization. Virtual Machine (VM) technology is the foundation for cloud migration, but for a complete solution that overcomes challenges with security, availability and performance, network services need to be incorporated into the virtualized architecture.
To meet the requirement for providing network services in the cloud Cisco has announced Unified Network Services (UNS) as a component of the Data Center Business Advantage architecture. UNS provides flexibility and choice in the adoption of network and compute services in both physical and virtual formats, unified by operation simplicity. The UNS architecture delivers a utility-based consumption model for network services that is promised by the cloud computing model. There are a number of technologies within this architecture including security, server load balancing and WAN optimization.
Let’s take look at application performance as an example of how network services enable application delivery from the cloud. As organizations move applications to the cloud performance is impacted due to the extra network hops back to the organization’s data center and out to the branch offices. To overcome performance issues organizations need to be able to easily deploy WAN optimization and seamlessly scale it in cloud environments. Cloud computing drives different deployment requirements for WAN optimization then with a typical data center based application deployment model. To deploy WAN optimization for applications in the cloud organizations need a deployment model that is agile and elastic, providing on-demand instantiation & provisioning. The WAN optimization service must be transparent to the location of the applications and to mobility of the application server virtual machines. For scalability WAN optimization needs to be multi-tenant without increasing the hardware footprint. A virtual form-factor is essential to achieve these requirements.
