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...



Hang on! It’s never too late to...



First get 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

(2000)

http://www.joelonsoftware.com/articles/fog0000000043.html





And the lesson we can learn is...



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)

- implementing a software factory

- for Maven/Java projects (mostly...)

- built on OSS tools

- 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)

all configured using PostgreSQL as database

with the same identity across all systems provided by OpenLDAP (directory server)



Redmine

http://www.redmine.org/

- wiki with markdown syntax

- multi-project issue trackerwith customizable workflow

- milestone planning

- integration with subversion and many more SCM...

- notifications

- GPLv3 license, built on Ruby and Rails


http://www.redmine.org

Jenkins

http://jenkins-ci.org/

- possibly the most widely used OSScontinuous integration server

- can ran as job scripts, ant/maven buildstriggered on specific conditions

- integration with subversion and many more SCM...

- extensible via plugins with rich directory:- sonar plugin- promotion plugin- artifactory plugin

- MIT licensed, built on Java


http://jenkins-ci.org

Subversion Edge

http://www.open.collab.net/go/csvne2_r2a/

- distribution of Subversion with toolsprovided by CollabNet

- web-based repository management

- web configurable LDAP integration

- basic web permission editing

- includes ViewVC repository viewer

- AGPL licensed, built in Java(excluding Subversion and ViewVC)





Artifactory

http://www.jfrog.com/products.php

- a generic repository managercan host artifacts and dependencies

- built for Mavenbut supporting also Ivy and Gradle

- remote REST APIssupports publishing via POST of generic files

- cache for external repositories, pre-configured with most used ones: (Maven Central, Codehaus, JBoss, Spring...)

- LDAP support

- LGPLv3 licensed, built on Java





Sonar

http://www.sonarsource.org/

- static code analysis and reporting

- statistics on code health

- plugin systemto support many languages beyond Java

- integrates well known tools:FindBugs, CheckStyle, PMD, Cobertura...

- LGPL licensed, built on Java and JRuby

OpenLDAP + web management provided by Zentyal

http://www.zentyal.org/

- web interface for Small Business Server

- based on Ubuntu Server 10.04 LTS

- all the configuration is on OpenLDAPhttp://www.openldap.org/

- we’re using just its user and group module

- can sync to external LDAP servereven Active Directory with password sync!

- 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!



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!



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...
