Let’s define a Software Factory
Once upon a time there was a little factory who was able to turn ideas into code...
...and make everyone happy!

But inside the factory truth was more often...
Like having a cat
in the waste bin...

The state we’re in... the Joel test
Let’s assess the status of
our working environment
using the test of Joel Spolsky:
12 Steps to Better Code

But trying to introduce tools can lead to some objections...
SOFTWARE FACTORY
TOOLS ARE EXPENSIVE LOTS OF THEM
ARE OSS AND ACTUALLY VERY
GOOD TOO
SETUP ISCOMPLICATED
I COULD TRYAND INSTALL
IN A VM
WHAT ABOUT TRAINING? WE
NEED TO DEFINE WORKFLOWS AND
PROCEDURES WELL...

What can we do...?
Software Factory in a Box!
- a Virtual Machine with an OSS OS (Ubuntu Server 10.04 LTS)
- built on OSS tools
- implementing a software factory
- for Maven/Java projects (mostly...)
- we can experiment best practices with

What’s inside the Software Factory in a Box...
The VM contents:
- redmine (issue tracker & wiki)
- subversion edge (scm + management tools)
- jenkins (continuous integration)
- artifactory (maven repository)
- sonar (source code reporting)
with the same identity across all systems provided by OpenLDAP (directory server)

OpenLDAP + web management provided by Zentyal
http://www.zentyal.org/

- provides self-service change password web

Let’s experiment with some best practices...
- use a wiki as project knowledge base
- slice requirement documents in issues and track them
- avoid “downloading the internet” with maven
- build project with dedicated maven repository
- one repository per project with standard trunk/tags/branches layout on subversion
- promote and release projects from the CI server
- share common project properties using a parent POM
- publish a documentation site for a project with maven
- monitor health state of source code through static analysis
- create our custom maven archetypes and publish them on artifactory
...and check if they’re fit for us! Let’s see some possible examples...

What’s next...
We can move our Software Factory in a Box
VM in the virtualized infrastructure of our
company datacenter!

Marcello Teodori - [email protected] – JUG Milano
What’s next too...
If we don’t want to host some of these tools...many of them offer a cloud service version...
- DEV@cloud by CloudBees for Jenkins
- Artifactory Online by JFrog
- many more for Redmine and Subversion
...but don’t forget to manage identityacross all services!
sabato 5 marzo 2011
Marcello Teodori - [email protected] – JUG Milano
Or yet what’s next again...
We can switch from Subversion to a more advanced SCM.....like Git for example!
And use instead of Subversion Edge as a distribution of Git with web management for user, repositories and permissions available as service and packaged...
