Berlin and Stuttgart say hello to Infinispan

image Last week I finally put together my presentation on cloud computing and Infinispan. To kick things off, I presented it at two JUG events in Germany.

Berlin’s Brandenburg JUG organised an event at the NewThinking Store in Berlin’s trendy Mitte district. Thanks to Tobias Hartwig and Ralph Bergmann for organising the event, which drew an audience of about 35 people. Cloud computing was the focus of the evening, and I started the event with my rather lengthy presentation on cloud computing and specific issues around persisting data in a cloud. The bulk of the presentation focused on Infinispan, what it provides as a data grid platform, and what’s on the roadmap. After a demo and a short break, Infinispan committer Adrian Cole then spoke about JClouds, demonstrating Infinispan’s use of JClouds to back cached state onto Amazon’s S3. You can read more about Adrian’s presentation on his blog.

Two days later, the Stuttgart JUG arranged for me to speak to their JBoss Special Interest Group on Infinispan. Thanks to Tobias Frech and Heiko Rupp for organising this event, which was held in one of Red Hat’s training rooms in Stuttgart. The presentation followed a similar pattern to what was presented in Berlin, to an audience of about 15 people.

In both cases, there was an overwhelming interest in Infinispan as a distributed storage engine. The JPA interface which is on our roadmap generated a lot of interest, as did the query API and to a lesser extent the asynchronous API - which could benefit from a better example in my presentation to demonstrate why this really is a powerful thing.

Overall, it is good to see that folks are interested in and are aware of the challenges involved in data storage on clouds, where traditional database usage is less relevant.

Many people have asked me for downloadable versions of my slides. Rest assured I will put them up - either as PDFs or better still, as a podcast - over the next 2 weeks.

Coming up, I will be in Krakow speaking at their JUG on Thursday the 23rd, and then in Dublin on Tuesday the 29th. Details of these two events are on the Infinispan Talks Calendar. Hope to see you there!

Cheers Manik

First experiences presenting Infinispan

Last week was one of the most exciting weeks for me since joining the Infinispan team because for the very first time, I was going to present Infinispan to the world :)

Firstly last Tuesday, I introduced Infinispan to Switzerlandhttp://www.jugs.ch/html/events/2009/infinispan.html['s Java User Group], where a crowd of around 20 people learned about the usability improvements introduced, the performance and memory consumption enhancements, and forthcoming new features. To finish the presentation, I showed the audience a demo of 3 distributed Infinispan instances connected to an Amazon S3 cache store via JClouds. I received some very positive feedback from the attendees who, in particular, were interested in finding out the differences between grid and cloud computing.

Two days later I went to Brussels to do the same presentation for Belgium’s JBoss User Group and the reaction was even better there! A lot of Spring developers attended the presentation who were very keen on integrating Infinispan in their own projects.

From here I’d like to thank all the people who attended these two sessions and in particular the organizers, Jakob Magun and Phillip Oser from Switzerland’s Java User Group and Joris De Winne from Belgium’s JBoss User Group.

Cheers, Galder

4.0.0.ALPHA6 - another alpha for Infinispan.

Yes, we’ve felt the need for one more Alpha. This alpha contains a number of bug fixes over Alpha5, as well as some new minor features. Please have a look at the release notes for details.

In addition to code changes, Vladimir Blagojevic has contributed a Doclet to generate a configuration reference. Check this out here. While not all config elements are properly annotated in this release - and as such the configuration reference is somewhat sparse - thanks to this tool, a more complete and up-to-date configuration reference is something you can look forward to in future releases.

Further, Alejandro Montenegro has started compiling steps for an interactive tutorial. Making use of a Groovy shell, this tutorial guides readers through most of Infinispan’s APIs in an interactive manner that would hopefully make it easy to learn about Infispan. Please do give this a try and provide Alejandro with feedback!

Please download and try out this release, and feed back with your thoughts and experiences!

Cheers Manik

Infinispan@JBossWorld

imageI will be presenting on Infinispan, data grids and the data fabric of clouds at JBoss World Chicago, in September 2009. I will cover a brief history of Infinispan and the motivations behind the project, and then talk in a more abstract manner about data grids and the special place they occupy in providing data services for clouds.

In addition, I expect to pontificate on my thoughts on clouds and the future of computing in general to anyone who buys me a coffee/beer! :-)

So go on, convince your boss to let you go, and attend my talk, and hopefully I’ll see you there!

Cheers Manik

Upcoming JUG and JBUG talks on Infinispan

image I will be speaking at a number of JUGs around Europe this month. In addition, other core Infinispan devs will also be making JUG and conference appearances. I’ve put together a calendar of events which you can track, or add to your Google calendar to monitor.

This is a great chance for folks to learn about Infinispan, cloud and distributed computing, and where the project is headed. Hope to see you at one or more of these events!

Cheers Manik
