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
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 ?
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
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
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)
Comparing PHP Stacks Linux + Apache + MySQL + PHP Windows + Apache + MySQL + PHP Windows + IIS + MySQL + PHP Windows + IIS + MS SQL Server + PHP
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
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
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
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
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
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
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)!
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
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!
Drupal via WebPI Fastest way to setup Drupal on IIS Takes care of all the steps Deploy of Drupal (6.x or 7.x) Dependencies PHP IIS: CGI, URL Rewrite, VC9, WinCache, etc , File permissions Database creation
Windows Cache Extension for PHP Open source project developed by Microsoft IIS Specific accelerator Requires PHP 5.2 or 5.3 x86 Non thread safe version Provides features not available in APC and other accelerators Current version: 1.1
Drush 5.x A command line shell and scripting interface Written in PHP MS SQL Server is supported Windows setup available on http://drush.ws/drush_windows_installer Takes care of all required dependencies Requires elevation
Drush aliases Create a file aliases.drushrc.php in %UserProfile%.drush$aliases[’drupal7] = array( root => /path/to/drupal, uri => dev.mydrupalsite.com, os => Windows, remote-user => Administrator, winrs-password => Passw0rd, remote-host => DrupalWeb1);
Server Farm IIS extensions: Application request Routing (ARR) Web Farm Framework (WFF) You can enable independently Load balancing and caching Server farm provisioning Platform / applications
WebDeploy Web Application Packaging Application or site, including DBs Sources and destinations can be Live servers Zip files Deployment Administrative rights not required Integration with VMSVC for remote deployment IIS server synchronization Entire server / site / application Differential Detects missing dependencies
