IIS 7.0 Editions and Windows
IIS 7.0 is available for both desktop and
server editions of Windows. On Windows Vista, IIS 7.0 offers Web administrators
and Web developers a complete platform for building and testing dynamic Web
sites and Web applications. IIS 7.0 running on Windows Vista also enables
process activation, process management, and the necessary HTTP infrastructure
for creating WCF–based applications.
The way IIS 7.0 works on Windows Vista depends on the edition of
Windows Vista you are using. On Windows Vista Starter and Home Basic editions,
IIS 7.0 cannot be used to host Web sites, Web applications, or Windows
SharePoint Services. On these editions, a limited set of IIS features are
available, such as Windows Activation Service components that are used to
enable WCF-based applications. Users who
install WCF-based applications will not need to install these components. The
necessary components are installed automatically by WCF. With these editions,
the simultaneous request execution limit for IIS is three, meaning that an
application or a group of running applications could make up to three
simultaneous requests for Web content through the installed IIS components.
On
Windows Vista Home Premium, most of the IIS 7.0 features required for Web site
development are available. The available features should allow most casual or
hobbyist administrators and developers to build and test dynamic Web sites and
Web applications. Many advanced features are missing, however, including
advanced authentication components, advanced logging components, and FTP server
components. As with Starter and Home Basic editions of Windows Vista, the
simultaneous request execution limit for IIS is three for Windows Vista Home
Premium, meaning you or running applications could make up to three
simultaneous requests for Web content through the installed IIS components.
For Windows Vista Business, Enterprise,
and Ultimate editions, all IIS 7.0 features are available. This means that
professional Web administrators and Web developers have everything necessary to
design, build, and test Web sites and Web applications. The simultaneous
request execution limit is ten for these editions of Windows Vista, meaning you
or running applications could make up to ten simultaneous requests for Web
content through the installed IIS components.
With server editions of Windows, you can
use IIS to host Web servers, Web applications, and Windows SharePoint Services.
All features of IIS 7.0 are available on all editions of Windows Server 2008.
On Windows Server operating systems, IIS 7.0 has no request execution limit.
This means that an unlimited number of simultaneous requests can be made to the
IIS 7.0 server core.
