RESONATE CENTRAL DISPATCH™: Providing Availability and Optimal Performance for Business-Critical Applications

Resonate Central Dispatch™ provides high availability and optimal performance for online services, ensuring a positive end-user experience. Managing all requests at the Web and application tier, Resonate Central Dispatch allows multiple Internet servers to act as a single, scalable, reliable, and easily managed Internet server system. Resonate Central Dispatch scales linearly and requires no feature trade-offs. It is the first and only traffic management product that provisions resources on-the-fly, allowing administrators to bring up and take down servers in real-time, for quick return on investment (ROI).

BENEFITS OF RESONATE CENTRAL DISPATCH

Information Gathering and Intelligent Action

Distributed software agents collect fine-grained detail such as CPU load and memory utilization to determine server health. Resonate Central Dispatch Schedulers test network latency and other pre-defined metrics. Based on the data collected from the agents and the tests performed by the Schedulers, Resonate Central Dispatch can take real-time, intelligent action, routing traffic requests to ensure maximum availability and performance. By effectively managing traffic, client requests are processed quickly and accurately.

High Performance, Scalability and Flexibility

Resonate Central Dispatch software solution scales as e-business applications grow, requiring no changes in existing hardware investments. When servers are added to an e-business infrastructure, Resonate software leverages the additional servers' processors for increased performance. With hardware-based traffic management products, responsiveness is degraded or feature functionality is sacrificed as usage and systems grow.

Just-in-Time Capacity Provisioning

E-businesses cannot afford to waste money on under utilized hardware. Resonate Central Dispatch enables administrators to increase the utilization of their assets while maintaining high availability and predictable performance for their end-users. Resonate Central Dispatch gives administrators the ability to dynamically bring resources on and offline and share resources across multiple applications and services.

Fastest Time-To-Value, For Quick Return on Investment

Resonate Central Dispatch is quick to deploy and can be up and running in hours or days. The open and extensible architecture enables administrators to integrate Resonate Central Dispatch into their existing infrastructure and deploy on the latest technology. And even better, Resonate Central Dispatch is easy to learn and use - users can be fully trained in just a few days.
