Process Manager
Starts worker processes when a listener (e.g. HTTP.SYS) receives the first request
Monitors state and health of worker processes
Recycles worker processes based on certain parameters, e.g. lifetime, number of requests,
schedule etc.
Prevents resource exhaustion, e.g. by limiting number of worker processes that can be active
at the same time.

FastCGI module allows IIS7.0 to host PHP
applications
High-performance version of CGI interface
used by many Web client applications
Build applications that deliver a visually
compelling user experience
Communicate across technology boundaries
Support a wide range of business processes
IIS 7.0/7.5 can run HTML, Classic ASP, ASP.NET, and PHP
applications, all on a single easy-to-manage platform

Enhancement to CGI protocol
Web server creates FastCGI process pool for very first request
Web server re-uses existing FastCGI processes for subsequent requests
Configurable Resources
Download for IIS 6
Ships in IIS 7/7.5, installed with the CGI feature
• Benefits of FastCGI for Windows
– Much faster than CGI because there is no process creation cost
– Much more stable than ISAPI because of single
threaded execution environment
Non-thread safe PHP builds are recommended for FastCGI

Aspiration
It’s a mess.
The “plumbing” associated with web
solutions should not get in your way
building great applications.
Reality
The Microsoft Web Platform Installer is our way of making that mess a
little easier to deal with.
It won’t take away all the pain of setting up an environment, but it takes
away a lot of it.
Today I’ll show Version 2 of the WPI and how you can
use it to set up your web environments.
Makes it simple for anyone using Windows Server or
Client to design, develop, discover, deploy and run
web applications.
Install the latest versions of FREE Microsoft Web Platform
tools, web server and extensions, database and frameworks
including
Stay up-to-date and explore what’s new.
