As a PHP developer building web applications is besides making a living a lot of fun too, especially when you can deploy your apps to any kind of environment and on any platform. In this session I take a non-standard PHP application (based on Zend Framework) and deploy it to a bare metal environment running LAMP, Windows 2008 Server with IIS7 and to cloud instances like Azure and Amazon. The goal is to provide information on how to deploy to these various environments manual and automatic, but also to show it doesn't really matter anymore what the targeted platform is, as long the apps are written in PHP.

7. Live Hacking

8. Good old days

9. FTP deploy

10. Manual FTP deploy

11. Version control

12. Code management

13. Versioning concepts

14. Symlink switch old
path/to/webapp
path/to/webapp-1.0.2 -> path/to/webapp
path/to/webapp-1.0.3

15. Symlink switch new
path/to/webapp
path/to/webapp-1.0.2
path/to/webapp-1.0.3 -> path/to/webapp

16. Automated deployment

17. Concept: build
• required steps
•- to “build” an application
validate
- test
- document
- package

18. All tools needed!

19. Phing
• build tool written in PHP
• comparable to ANT build scripts
• impressive list of task templates
• extensible for missing tasks

20. Phing HelloWorld!
<?xml version="1.0" encoding="UTF-8"?>
<project name="demo" default="build">
<target name="build">
<echo msg="Hello World!"/>
</target>
</project>

22. Export from SVN
<property name="buildpath" value="./build"/>
<property name="repopath"
value="https://svn.myserver.com/demo/trunk"/>
<target name="prepare">
<delete dir="${buildpath}"
includeemptydirs="true"
quiet="true"
verbose="false"
failonerror="false" />
<mkdir dir="${buildpath}"/>
</target>
<target name="getsources" depends="prepare">
<svnexport svnpath="/usr/bin/svn"
force="true"
nocache="true"
repositoryurl="${repopath}"
todir="${buildpath}"/>
</target>

25. Anywhere deployment

26. Deployment options
• platform (windows, linux, i5, …)
• database engine (mysql, ms sql, oracle)
•- deployment protocols
rsync
- FTP

27. Linux server

28. Example deploy Linux
<target name="deploy-linux">
<exec dir="./build"
command="rsync -rq user@server.com:/srv/www/
demo"/>
</target>

30. Windows server

31. Deploy to windows
<target name="deploy-windows" depends="version-bugfix">
<ftpdeploy host="${env.win-prod}"
port="21"
username="${auth.win-prod.username}"
password="${auth.win-prod.password}"
dir="/"
mode="binary"
clearfirst="false">
<fileset dir=".">
<exclude=”./library/Zend”/>
<exclude=”./library/ZendX”/>
</fileset>
</ftpdeploy>
</target>

32. Windows Azure

33. A few remarks
•- runs only on windows
but still uses phing :-)
• takes a considerable time to upload
• instances are defined in the config

34. Setting properties
<property
name="cmd-cspack"
value="c:Program FilesWindows Azure SDKv1.3bin
cspack.exe"
override="false"/>
<property
name="cmd-csrun"
value="c:Program FilesWindows Azure SDKv1.3bin
csrun.exe"
override="false"/>

35. Prepare for Azure
<target name="prepare-azure" depends="version-bugfix">
<!-- start building in ./bldtmp -->
<mkdir dir="./bldtmp" />
<copy todir="./bldtmp" overwrite="true">
<fileset dir="./deploy/azure">
<include name="**/*.*" />
</fileset>
</copy>
<copy todir="./bldtmp/PhpOnAzure.Web" overwrite="true">
<fileset dir=".">
<include name="**/*"/>
<include name="*"/>
</fileset>
</copy>
</target>

36. Deploy to Azure
<target name="deploy-azure" depends="prepare-azure">
<exec command="&quot;${cmd-cspack}&quot;
ServiceDefinition.csdef /
role:PhpOnAzure.Web;PhpOnAzure.Web /out:PhpAzure.cspkg"
dir="./bldtmp" />
<mkdir dir="./release/${phing.project.name}-$
{version.number}/azure-prod" />
<copy todir="./release/${phing.project.name}-$
{version.number}/azure-prod" overwrite="true">
<fileset dir="./bldtmp">
<include name="PhpOnAzure.cspkg"/>
<include name="ServiceConfiguration.cscfg"/>
</fileset>
</copy>
</target>

39. Continuous Integration

40. Continuous Building

41. Considerations

42. Some reminders
•- design your apps to work everywhere
use OOP abstraction layers
- use plugins
- take care of sessions!
• investigate “the other platform”
- gives you a head start over competetion
- teaches you the caveats
• “cloud” solutions are in high-demand
- see what works best for your customer

43. automate what you might
forget under stress!
