Accelerate Application Performance to Enable IT Consolidation

Many organizations are consolidating, or centralizing, IT today. IT consolidation provides many benefits, including simpler, easier to manage applications and infrastructure. But accelerating application performance is key to a successful IT centralization project.

Application performance optimization is an important component of consolidation because users are required to perform many more transactions over the wide area network than before. In a consolidated environment, data requests such as those for files or emails that were previously served by local infrastructure must now take place over the WAN. Without a wide-area data services solution in place to accelerate applications, these requests could result in congested networks, poor application performance, and frustrated users.

IT Consolidation Benefits and Challenges

Benefits Challenges
Cost savings of reduced IT infrastructure Performance limitations of applications over the WAN
Simplified management process Limited WAN bandwidth
Easier data backup One-time costs associated with consolidation
More secure data and infrastructure

Whether an organization is focused on consolidating file servers, email servers, SAN or NAS devices, or remote tape backup libraries, wide-area data services solutions will accelerate application performance typically by five to 50 times and in some cases up to 100 times over the WAN, and reduce WAN bandwidth utilization typically by 60 to 95%. These application performance improvements ensure that remote users can successfully access consolidated data and applications, while the resulting WAN bandwidth optimization ensures IT managers that they can minimize or altogether delay additional bandwidth investments. Users will feel as if they getting the performance of local infrastructure, while the organizations get the benefits of IT infrastructure that is consolidated, such as lower costs, more security, and eased regulatory compliance.

Using Riverbed, organizations can consolidate all types of servers from a branch office with one simple plug and play appliance. They can greatly reduce the cost and complexity of remote office infrastructure while guaranteeing the performance that end users need.

Optimize WAN Bandwidth

Reduce Network Traffic with WAN Bandwidth Optimization

Many enterprises use WAN bandwidth optimization in order to cut costs and relieve network congestion. But typical WAN optimization products only reduce network traffic by ten or twenty percent. In contrast, a wide-area data services (WDS) solution can reduce network utilization typically by 60 to 95%.

Data Streamlining provides better bandwidth optimization

Riverbed removes repetitive traffic from your WAN through patent-pending Data Streamlining algorithms. Data Streamlining stores your WAN traffic on disk in a proprietary, application-independent form that can be reused by any application, any file or any user that sends or receives the same data. Whether a client requests a file that has been renamed, emails an attachment or uses another application like FTP or a Web-based application, any traffic that is generated that has been across the network before will not be retransmitted.

Instead, only a small reference to the data is sent to the Riverbed Steelhead appliance on the opposite side of the network. Riverbed's references are 16 bytes in length, yet can represent megabytes of data, which results in high levels of WAN bandwidth optimization.

Riverbed delivers more than just WAN optimization

Unlike WAN optimization products, Riverbed Steelhead appliances deliver much more than reduced network traffic. Riverbed not only provides the best WAN optimization available today, but also improves the throughput of your applications - because it's more than limited network bandwidth that slows down your applications. Most vendors focused on WAN bandwidth optimization do not offer true application acceleration, which are different and distinct challenges. Riverbed leads the pack on both.

Wide-area Data Services

Improve Application Performance with Wide-Area Data Services (WDS)


Given the importance of anytime, anywhere application access, IT departments are turning to wide-area data services to improve and accelerate application performance across the wide-area network (WAN). Using WDS, IT can provide LAN-like access to data and applications anywhere throughout the enterprise network, enabling real-time collaboration for users in branch offices and mobile workers all over the world.

Riverbed is the pioneer and market leader in WDS - the first comprehensive solution to a host of severe problems that plague enterprise applications operating across the WAN including:

  • Poor application performance
  • Insufficient, expensive or congested network bandwidth into remote offices
  • Difficulties in IT consolidation
  • Challenges with slow remote data backup and replication
  • Increasing demands of the mobile workforce

Unlike point products that improve one part of the wide area performance problem - like data compression, QoS, or TCP optimization - WDS is a comprehensive solution to application performance problems.

Riverbed's market-leading WDS solutions address all of the issues that affect application performance over the WAN, improving the throughput of applications enterprises rely on every day - including file sharing, email, backup, SSL, document management systems, and IT tools, as well as ERP and CRM solutions.

Wide-area Data Services

WDS encompasses several different product categories. Whether an organization is seeking to make the most of its existing investment in WAN bandwidth by reducing traffic, or aims to accelerate the performance of its global applications by addressing latency and chatty protocols, the optimal solution addresses all aspects of the problem at once.

WDS is the superset of several existing categories:

  • Application acceleration
  • WAN optimization
  • Wide area file services (WAFS)
  • QoS and traffic shaping
  • Web caching

Unlike these individual approaches that only address a single cause of poor application performance acrossthe WAN, a complete WDS solution enables the benefits of all of these approaches within a single, unified architecture.

Using WDS, enterprises can improve application performance across the network typically by 5 to 50 times and in some cases up to 100 times, and can simultaneously reduce WAN bandwidth utilization by 65 to 95%. These dramatic results allow businesses to take advantage of their networks, infrastructure, and applications in ways that they had never imagined possible.

An Integrated Approach to Improving Application Performance

WDS solutions accelerate applications by taking an integrated approach to application performance across the WAN. While some approaches solely focus on network optimization, or just concentrate on acceleration for a specific application, WDS combines an application-independent foundation that improves the performance of all applications running over TCP, with an application-specific set of modules that address chatty application protocols. This combination enables WDS solutions to accelerate the applications that enterprises care the most about, and provides the ability to easily add more functionality over time. WDS products are architected to scale all the way from the largest data centers with clustered appliances down to software on a single user's laptop (or desktop).
