Quality of Service (QoS) for Web Applications
This session will demonstrate how many networking concepts and techniques related to Quality of Service (QoS) can be mapped and applied to web clients, web services, applications and runtimes providing an end-to-end resource management conceptual framework that offers resource protection (via call shaping & policing) as well as request prioritization based on contextual & dynamic classification. It puts forward the argument for applications to be viewed more like the underlying networking layer, adopting many traffic engineering and quality of service optimizations techniques. It presents a mapping guide from one domain to another and then shows how this has been implemented in a solution that offers a production QoS solution for applications developed in Java, Scala, JRuby/Ruby and Jython/Python as well as all other JVM languages and eventually other runtimes/platforms including Microsoft’s .NET/Azure.
This session will also outline how QoS as applied to runtimes can be mapped to all execution points in the delivery of web based software services from client devices to backend services. It will demonstrate a working proof of concept using Apache web servers and app containers.

The much more relevant demo I did not get time to perform is documented in the blog entry below though in a mock form.

Thanks Ian and Paul,
Not trying to excuse myself completely here but my session was shortened because of the previous speaking over running and I had pretty much lost my voice because of a very bad eye/throat infection.
Clearly I took on far too much in such a session going from performance measurement/collection, feedback/loops, self adaption, metering and then QoS. But to be honest my goal was to inspire people to think differently about how they tackle app mgmt today in terms of performance and control. I wanted to give them a glimpse of what is achievable (what we have done).
I dumbed down the slides because I was concerned that people might think it was a sales pitch but it looks like I went too far. Sorry.
Agreed with comment from Paul. There was some thought-provoking material here but some of the concepts could have been developed further.
There was a lot of great material and conceptual stuff in this talk – applying machine learning, feedback and the leap in thinking of applications in terms of QoS.
From discussion with others I think some attendees found it hard to join up the abstract with the concrete. A less trivial demo may have helped.
