SOA WSJ: How does Wily provide deep visibility into web service components? What sort of performance increases can customers expect? What sort of uptime improvements can they expect?

KJ: Using Wily’s Byte Code Instrumentation technology, the Wily Web Services Manager (WSM) solution provides 100% visibility into web service performance without requiring any coding. Depending on your perspective, Wily WSM can display performance metrics from the client side, the server side or both to help determine how the client, server and network are performing.

Wily WSM also utilizes Wily’s Blame technology to decompose service calls into the underlying components of a service. Not only can you see the EJB invoked by the service, but you can also see file system I/O, JDBC calls, etc. This deep visibility endows customers with the ability to proactively manage service performance. By understanding that a service is dependent upon an EJB, operators can monitor the EJB thread pool as advanced warning of a service’s availability.

Proactive SLA management is what gives our customers a pronounced lift in their IT environments. The results will vary from environment to environment.

SOA WSJ: Are SOAs generally too loosely-coupled to manage effectively? Does their negative potential for downtime outweigh their positive potential to push information out to customers and suppliers?

KJ: SOA’s create complexity, but this complexity can be controlled with effective management tools. SOA’s require that organizations view their technology differently – application silos are now often seen as liabilities, not an effective strategy for simplicity. Today, because of SOA’s, technology is more about the transaction itself as it crosses multiple applications, it’s about the business process.

This shift also means we need to look at management technology differently. Silo’ed management will not work in SOA. Enterprises need a solution that has deep, broad visibility. When Wily invented application performance management we saw this coming, and today Wily is the only management vendor to provide end-to-end deep visibility across the IT infrastructure, in real time, 100% of the time.
