Mailserver Konferenz 2011: Mail ist nicht kompliziert, nur sehr komplex

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.

Configuration Management with Subversion and RPM

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:

I just gave my talk at the LinuxTag 2011 about Self Service Virtualization as private Cloud and my new Open Source project Lab Manager Light.

From the audience of about 80-100 people there where quite a few interesting questions and also several "I wish you had done that last year" comments.

Who is responsible for sustainability in IT projects?

After I got very worked up again yesterday about people asking for "quick help" in setting up something and nobody thinking about the long term sustainability of IT operations I would like to point out a few facts about this topic:

The major part of IT project costs are not related to the initial setup!

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:
Therefore I would like to suggest to alway strive for a simple solution and take the follow-up costs like maintenance, updates, security fixes etc. into account during the planning stage.

This is also a golden opportunity to include the original requester in the discussion about TCO and about who will actually spend their time on the follow-up tasks.
