Happy 2011 Everyone! If you judge my output by blog posts, it would seems like I took 2010 off. Fortunately, Oracle and Coherence did not take the year off. In fact, 2010 was a great year for Coherence, as we released Coherence 3.6, started a new Special Interest Group (Toronto), and continued to see our market presence broaden across geographies and industries.
The continued growth of Coherence, the Sun acquisition and the Exalogic announcement will make 2011 an even more exciting year. The combination of Exalogic, Coherence, and Oracle's JVM technology (Sun Hotspot and JRockit) provide tremendous synergies, and I am fortunate to be working at the epicenter these technologies.
Looking back for me personally in 2010, I had the opportunity, in addition to hosting the New York SIGs, to present at several Coherence SIGs where I talked about Coherence in the Cloud and Application Performance Management.
That latter talk, written by my outstanding colleague Randy Stafford, provided impetus for a broader talk focused on achieving success with Coherence. Randy's talk spoke about the need to track performance over the course of time, so you can see how changes in the environment (e.g. client load) impact Coherence application performance. While giving this talk in Toronto, it occurred to me there is really nothing special to performance: Randy's observation can be generalized to tracking any business metric that is important to the customer. In other words, if latency is what is critical to you, track latency over time (and the causes of potential latency). But if data source offload is what is important to you, track that instead. Not only does the old proverb "you can only improve what you measure" here, but only by measuring what you care about can you quantify the business value created by your application.
I will be touching on this theme during a talk at next week's New York Coherence SIG. The presentation will discuss many aspects of what you need to think about organizationally in order to be successful with Coherence. I have tentatively titled the talk "From Tactical to Strategic Success with Oracle Coherence."
The SIG will also feature a sneak peak, courtesy of Rao Bhethanabotl, of the upcoming release of the Coherence Management Pack for Oracle Enterprise Manager and presentation from Aleksander Seovic, consultant extraordinaire and author of Oracle Coherence 3.5, on synergies and challenges of running Coherence on the Amazon Web Services cloud.
