Am 26. und 27. Mai fand in Berlin die 5. Mailserver Konferenz bei Heinlein Support statt. Eine Konferenz von und für Spezialisten, war es für mich lohnen und hat mal wieder bestätigt, dass das gesamte Thema Email zwar nicht sehr kompliziert ist, in seiner Gesamtmasse and Details aber ziemlich komplex. Da in der iX mein Konferenzbericht erscheint, gibt es hier jetzt nur meinen Mitschrieb in Rohform.

Today I released the first part of our new Open Source Project YADT - an Augmented Deployment Tool . The configuration management with the help of RPM packages and a subversion repository is now available via the project repository . At the Subversion Day Berlin 2011 I gave a talk about how we do configuration management with RPM packages at ImmobilienScout24: Me showing the ImmobilienScout24 recruiting slide (Picture courtesy of H.

Operations, maintenance, updates, bugfixes, application administration, backup and disaster recovery exercises make up the majority costs and should not be neglected in the initial planning. Actually, the more a project is meant to be temporary, the longer it will run and the more it will cost in the end. To underline my personal beliefs in this matter I found the following links on the Internet, I am sure that with some time on Google you can find even more: Distribution of Cost Over the Application Lifecycle - A Multi-Case Study This study show very nicely how up 60-90% of total project costs over 5 years are recurring costs ( Figure 3 ).
