Appistry Brings ``Real-Time'' Capabilities to Grid Computing With Addition of New Workload Management Features to Appistry Enterprise Application Fabric.

SAN DIEGO -- Appistry:

-- New Capabilities Announced at the Gartner Application Integration and Web Services Summit 2006 Optimize Appistry EAF's Allocation of Resources, Allowing Time-Critical, CPU-Intensive Applications to be Easily Deployed Across Networks of Commodity-Grade Computers

Appistry, the pioneer and leading provider of application fabric software, today announced new workload management capabilities for its flagship product, Appistry Enterprise Application Fabric (Appistry EAF) from the Gartner Application Integration and Web Services Summit 2006. The additions and enhancements include a framework for applying workload management policies and initial support for three policies: an exclusive execution policy, a persistent execution policy and a limited execution policy. The new functionality enables enterprises deploying time-critical, CPU- and data-intensive applications to realize the scalability and affordability of grid computing, while also benefiting from the reliability and manageability inherent to application fabrics.

The supported policies provide for the timely completion of fabric tasks by allowing workloads to demand additional compute capacity as needed. With policies in place, the application fabric software is able to optimally allocate resources to demanding applications built in C/C++, Java or .NET, and better manage application performance based on workloads and events.

--An exclusive execution policy provides a mechanism for ensuring the efficient utilization of processors within an application fabric, by granting specific task instances exclusive access to the hardware on which they run. The fabric software's distributed scheduling algorithm then ensures no new work is given to a machine running an exclusive task.

--A persistent execution policy provides a mechanism for ensuring that specific tasks are either always running within a fabric, or are run on a set schedule. The fabric software then automatically provides "watchdog" functionality, enforcing the policy and ensuring that the required instances are running in the "background" at all times.

--A limited execution policy provides a mechanism for limiting the number of concurrent instances of a specific task. The fabric software's distributed scheduler then ensures that the number of concurrent allowable instances is not exceeded.

Unlike the traditional grid computing approach which relies on using spare CPU cycles on separately-managed resources to provide computing power, Appistry EAF creates a self-managing, "real-time grid" environment out of standards-based computers and operating systems. This difference is very important for several reasons. Most importantly, Appistry's architectural approach allows application fabrics to provide support for large-scale applications that are time-sensitive and thus unable to withstand the latency and unpredictability associated with traditional grids. Further, this approach allows application fabrics to virtualize the commodity hardware nodes into a single system, enabling developers and administrators to view and manage the hardware as if it were a single computer. Finally, this architecture provides application-level fault-tolerance, rather than depending - as traditional grids do - on the reliability of a collection of heterogeneous infrastructure resources under distributed control.

"The motivations for using a grid to create a more powerful, larger, single virtual system, or to produce a less expensive alternative of the same size as the systems it is replacing, are powerful factors that compel many organizations to look at possible grid solutions," stated Carl Claunch, Research Vice President of Gartner, Inc. "The ability to create a virtual supercomputer that is faster than the largest traditional design opens the door for sizeable long-term rewards."

"Our customers come to us because they need to deploy, scale and manage the most computationally demanding business and engineering applications created by today's highly competitive 'real-time' environments," said Kevin Haar, president and chief executive officer of Appistry. "At the same time, they desire the cost advantages of standards-based, commodity-grade computing. Our new workload management capabilities help us deliver all these in one easy-to-deploy software product, providing all the benefits of high-end, 'real-time' computing, at an affordable price-point."

Availability

Appistry EAF with workload management is available immediately for Intel and AMD-based servers running the Microsoft Windows and Linux operating systems.

About the Gartner Application Integration and Web Services Summit 2006

The Gartner Application Integration and Web Services Summit 2006 is the most focused event of its kind designed to help enterprises prepare for the challenges of the changing nature of software infrastructure and what it means for integration, web services and architecture initiatives. Gartner Application Integration and Web Services Summit hits the critical spot between the strategic planning and tactical advice IT organizations need to benchmark strategies on Web services security, SOA, EDA, ESB, application process and data integration, standards, and more.
