Mercury Interactive last week unveiled a handful of products designed to help customers make better sense of how applications use infrastructure resources and to optimize that infrastructure to support the most important apps.

The company announced about a dozen products and upgrades into what it calls Optimization Centers: IT governance, quality, performance and business availability. Best known for its testing and tuning software and services, Mercury said last year it would expand its products to manage applications and compete with BMC Software, Computer Associates, HP and IBM.

Among the announcements last week were:

• Capacity Planning: software in the performance portfolio that can provide "what-if" analysis on infrastructure and software. The software can test existing network resources against the resources a new application requires, such as bandwidth, CPU on servers and response times on network devices. The collected metrics would help network managers make better investments and determine the cost-effectiveness of rolling out that application, Mercury says.

• Customer Impact: new software in the business availability group that can determine the effect on customers when infrastructure or application performance degrades. The software provides visibility into the availability of applications and systems.

• Performance Tuning: upgraded software in the quality category that includes the best practices for managing PeopleSoft and Siebel Systems applications.

"Mercury is way beyond its testing beginnings and is approaching managing applications from a higher viewpoint than the other guys," says Glenn O'Donnell, a research director at Meta Group. "It is looking at applications from a service perspective, whereas the big guys [BMC, CA, HP and IBM] started out in infrastructure management and are still working up the stack."

Several of the company's new products can be attributed to a summertime buying spree. Mercury, with its $22.5 million purchase of Performant in May, picked up performance testing and tuning technology for Java 2 Platform Enterprise Edition applications. And with the $225 million Mercury put down for Kintana, the company now can incorporate Kintana's business service management technology into new software products such as Business Process Testing and Topaz Service Level Management.
