Is your web monitoring out of balance? Are you giving enough attention to API, REST and SOAP – especially as companies expand the web application partner channels and mobile applications? Join us on Thursday, June 20 at 2:00 p.m., as Dell product expert John Spirko leads a panel of web professionals who manage a very popular, very busy website. These members of Dell’s DevOps team will discuss the attributes of a SOAP request/response pair, why URL identification isn’t enough to pinpoint SOAP API issues, the two main perspectives to consider for SOAP API monitoring, how to deal with – and solve – real-time issues and much more.

The panel includes: Rob Dickinson – Lead Architect for Dell’s Performance Management product portfolio and member of the W3C “Web Performance Working Group.” Juan Carlos Estibariz – Web Performance Management Software Developer and member of the W3C “Web Performance Working Group.” Matthew Vann – Performance Engineer for Dell.com’s DevOps core, specializing in transaction tracing and memory profiling across a variety of IT stacks. Andy Wahrenberger – Operations Engineer for Dell.com’s DevOps core, specializing in performance stability across 300+ database and 400+ .NET applications.

My recent work has been around use cases that have to do with API’s and their effect on user experience but also the effect on business to business relationships. This is basically where your web application performance becomes dependent on some other system that is outside of your control or your application impacts another web application’s performance. It’s interesting, from a technologist perspective, to look at the many different ways that websites interact with other businesses through the use of APIs. There are the obvious use cases like native mobile applications that allow devices to interact through APIs instead of using web pages. There are also less obvious use cases such as an application that has to validate a business as part of an online process where part of the validation requires the application to do a Federal Tax ID lookup with the IRS.
