  • 1. Windows Drupal Alessandro Pilotti @alexpilotti MVP ASP .NET / IIS Windows Azure InsiderMCSD, MCAD, MCSE, MCDBA, MCT Red Hat Certified Engineer
  • 2. Some Facts About the Windows OS—  Based on Windows NT, released in July 1993—  Hardware independent OS—  POSIX subsystem—  Provides excellent command line tools —  PowerShell—  Excellent security model—  Server Core option for minimal GUI and footprint
  • 3. Windows and IISProduct Name OS Version IIS ReleaseWindows XP 5.1 5.1 08/01Windows Server 2003 5.2 6.0 03/03Windows Vista 6.0 (Build 7.0 01/07 6000)Windows Server 2008 6.0 (Build 7.0 03/08 6001)Windows 7 6.1 7.5 07/09Windows Server 2008 6.1 7.5 07/09R2Windows 8 6.2 8.0 ?Windows Server 2012 6.2 8.0 ?
  • 4. IIS 6—  Kernel level component (http.sys) listens to HTTP requests —  HUGE performance improvement over IIS 5—  All user code runs in separate processes —  Worker Process (w3wp.exe) —  Crashes in worker processes don’t affect the stability of the service—  Web gardens —  Multiple WP per single web applications—  Configuration stored in a XML metabase —  MetaBase.Xml —  MBSchema.Xml
  • 5. IIS 7.x / 8.0—  Complete redesign over IIS 6.0—  Modular design—  http.sys is still part of the architecture—  Improved remote administration and delegation—  Enhanced command line and scripting tools —  Including PowerShell cmdlets—  Flexible model not limited to HTTP—  Tight integration with WCF
  • 6. Security—  Windows is a very secure OS! —  Running Internet Explorer as administrator and getting malware does not mean that the system is flawed —  RunAs permits to execute processes as different users—  Windows Server 2008 introduced some unique security features—  Windows Firewall—  Since Windows Server 2008: —  Address space layout randomization (ASLR) —  Network Access Protection (NAP)
  • 7. Comparing PHP Stacks—  Linux + Apache + MySQL + PHP—  Windows + Apache + MySQL + PHP—  Windows + IIS + MySQL + PHP—  Windows + IIS + MS SQL Server + PHP
  • 8. Linux + Apache + MySQL + PHP—  Pros —  Most known and deployed stack in OSS world —  Linux is a highly configurable operating system —  Most Linux distributions can easily be configured for Apache, MySQL and PHP (yum / apt-get / etc) —  Apache is a highly modular and scalable web server —  Lots of documentation available —  Tightly integrated update process (yum / apt-get)—  Cons —  Lack of simple configuration tools —  Configuration requires a wide knowledge —  Deployment differences between distributions
  • 9. Windows + Apache + MySQL + PHP—  Pros —  Most of the components are shared with the LAMP stack —  Suitable for solutions that require integration with both Apache modules (e.g. mod_rewrite) and Windows —  Until FastCGI for IIS showed up, undoubtfully the best PHP stack on Windows —  Tools like XAMPP provide an easy deployment option —  http://en.wikipedia.org/wiki/Comparison_of_WAMPs—  Cons —  Performance —  Limited documentation and examples —  Limited integration in the Windows ecosystem —  Heterogeneous scenario for security updates
  • 10. Windows + IIS + MySQL + PHP—  Pros —  Performance (FastCGI and WinCache) —  Tightly integrated in the IIS 7.x ecosystem —  Easy to configure an deploy via WebPI —  Easy to manage via IIS Manager —  Easy to script via WebDeploy and Powershell—  Cons —  Web apps requiring integration with Apache modules need to be reviewed
  • 11. MySQL and Microsoft SQL Server—  Using PHP Data Objects PDO eases portability issues—  SQL Server is a choice to evaluate in scenarios that require high availability—  PHP Drivers for SQL Server 3.0 just released!—  Drupal + SQL Server through Commerce Guys module
  • 12. PHP on Windows—  COM integration —  Simplest way to access OS native 3rd party features —  Marshaling performance is not brilliant (IDispatch / late binding)—  .NET integration (experimental)—  W32Api (experimental) —  Register / Invoke API functions —  Be careful with the parameters on the stack—  win32service —  start/stop/register/unregister services—  Note: flock() has a slightly different behavior on Windows
  • 13. IIS 7 Modules—  Individual features used to process a request—  Executed in a pipeline—  Native —  OS specific binaries (e.g. written in C++) —  More performant—  Managed —  .NET assemblies, executed by the .NET CLR —  More secure and manageable
  • 14. Windows Server 2012 - SNI—  Windows Server 2012 introduces some important features —  Huge performance improvements for multi-tenant!—  Server Name Indication (SNI) —  Assign different X509 certificates to different host headers —  Requires IE >= 7.0, Chrome >= 6.0, FF >= 2.0, SafariMobile >= 5.0 —  Non supported in IE on Windows XP (even on IE 9)!
  • 15. CPU Throttling—  CPU resource pooling is a problem in IIS 7.x —  Processes exceeding their quota get killed, not throttled —  Lots of errors in user applications —  Not suitable for multitenant scenarios—  This feature required specific kernel support
  • 16. Windows Server 2012 CPU Throttling
  • 17. WebPI—  Microsoft Web Platform Installer (WebPI) is a free tool that simplifies deployment of web solutions —  IIS features and extensions —  WinCache, PHP Drivers for SQL Server, PHP Manager —  Frameworks —  PHP 5.2 / 5.3, .Net, etc —  Web applications —  Drupal, Joomla, Wordpress, DotNetNuke, Orchard, etc —  Database —  MS SQL Server Express, MySQL, etc —  WebMatrix —  WebMatrix 2 RC available!
