In this video Steve Horwath, Product Manager at Cable & Wireless, talks with Stephen Makayi, Marketing Manager at Cisco, about the growing demand for application performance and the Cable & Wireless managed WAN optimization service, which provides customers with optimized application performance with advanced reporting, which in turn give customers information they can use to drive their business. Steve discusses how APM enables managed service providers to deliver an application-aware network with uptime guarantees for applications that changes the conversation MSPs can have with customers, from selling plain WAN links to providing application performance assurances, and putting the MSP in the role of a trusted advisor.

The Olympics give us a chance to marvel at and enjoy the performances of athletes who demonstrate their intense dedication to the pursuit of excellence and their determination in the face of fierce competition. The games are a worldwide event and with audiences in the home countries anxious to see their athletes’ performances national television stations also have a challenge that they must meet. Fuji TV of Japan is no exception. With a long history of Japanese participation in the winter Olympics and a large home audience to serve, they have set up shop in Vancouver. Making this trip can be a costly undertaking and given the distance back to Japan they needed help in keeping communications smooth and keeping costs down.
To communicate with the home office Fuji TV set up a dedicated line between the company’s data center in Odaiba, Japan and the Olympic Media Village in Vancouver, a distance of over 7500 km. This connection provides Intranet access enabling the on-site staff, including production and news employees, to access the head office file servers and use its systems. This long distance WAN access allows Fuji TV to avoid having to transport and install data and application servers at Vancouver and thus avoid the cost of additional on site staff to maintain these servers. By reducing staff the costs savings is considerable, including air travel, housing, transportation and food.

Forrester says that WAN optimization is increasing in importance to IT organizations and that business issues such as consolidating branch office servers and rolling out new collaborative applications are driving its adoption. This is because companies rely on the WAN for delivery of their business-critical services, but the WAN suffers from poor performance because of latency over distance.
Forrester advises that WAN optimization technology plays a critical role in improving application performance by using techniques such as caching, protocol optimization, compression, traffic management and quality of service (QoS), to increase effective throughput and mitigate latency, while providing visibility into the traffic mix.

Enterprise IT departments are continuing to invest in technologies that generate cost savings while making their business applications more agile and available. These initiatives, such as consolidation of branch-office servers and virtualization of data center servers, are increasingly being adopted by the enterprise; however, they have not been without consequences. For example, branch-office server consolidation projects, while reducing the server footprint, can result in a poor end-user experience and increased bandwidth utilization because applications traverse a WAN link with higher latency and packet loss and lower bandwidth than they traverse a LAN link. WAN optimization solutions, such as Cisco® Wide Area Application Services (WAAS), are implemented to deliver LAN-like application response times for end users and to defer a WAN bandwidth upgrade.
For example by hosting virtual desktop images on the Cisco Unified Computing System organizations can greatly increase the number of images per server while reducing complexity, by taking advantage of capabilities such as memory capacity, virtualized adaptors, Unified Fabric and centralized management that is integrated with solutions from VMware.
By using Cisco ACE to provide server load-balancing services organizations can greatly increase the number of user sessions per server, while increasing system security, by taking advantage of SSL off load and TCP reuse capabilities and built in intelligent security functionality, and they can realize cost reduction through virtualization capabilities and integration with provisioning systems from VMware.
