JAOO Day 3
Today was the last conference day for JAOO 2007 and I will visit the Scrum Master Class for the next to days. No Keynote today so even Track Host Frank Buschmann was a little bit confused and came to late to open his Track. Never the less the first speaker was Wayne Fenton the Director of Architecture form eBay. As I posted I met him already the first day at the Conference Party. He spoke about Operational Scalability and how scalability is on of the big requirements for his company. His talk was quit interested because he gave an overview how eBay reached the goal that their system scales very well. He explained a little bit about their production line and how they are doing deployment which I will post about soon.
The second Talk was given by Robert S. Hanmer about Fault Tolerance once again in the Architecture Quality Panel. Robert is working for Alcatel-Lucent where he developed Software that helps to achieve 99.999% of availability by designing fault tolerant systems. The systems need a possibility to detect faults. If they have detected one they are using different strategies form simple reinitialization up to whole reboots to bring the system as fast as possible back to a working state.
After lunch, which is a little bit to South African like for me this year, Kevlin Henney talked about Performance Art. The main message was that Performance matters in every system but as one person said at the end - It does not matter what Kevlin is speaking about, his talks are just great.
The last Talk I visited this day was by Rebecca Wirfs-Brock about Lessens Learned in architecture. She is an consultant and had the chance to see several different architectures. It was interesting that she spoke not that much about the architectures it self further more how she is dealing with the challenges in projects as consultant.
At the end there was an Panel Discussion. What I take from it is normally the design or architecture of a product is not bad at the beginning. I mean nobody want to build a system he cant extend and maintain in the future. Further more there is a leak in communication so that developers do not understand the architecture and therefore the the code gets to a big ball of mud. There was one quite interesting comment form a guy of the audience. He admitted that they are doing architecture documentation on small movies. Several on the panel and I like the idea. I have to try it out.
The finishing panel was held as Podiums Discussion by Martin Fowler, Diana Larsen, Erik Dörnenburg, Erik Meijer and Eric Evans. They did some retrospective on the conference and what they fascinated them.
At the end I have to say the three conference days of JAOO 2007 where grate. I had a lot of fun and learned several new things. I am just wondering why we got no Conference T-Shirt this year but at leas everyone got a bag. So, now I will go out with Rupert for some beer to discuss the last two days a little bit. I am really thinking if I will come to this conference next year again. Definitely it is the best i have ever been to, but lets see maybe we will be able to do something like the JAOO in Vienna for the next Year.
