Web Server and Application Server Roles For Server 2008, IIS 7.0, or 2008 R2, IIS 7.5, with
IIS 6.0 compatibility must be installed. This makes sense. SharePoint is web-based because
IIS allows Windows Server (2008 or higher) to host websites and service HTTP requests from
clients. Many SharePoint capabilities are dependent upon and colored by the functions and
needs of IIS. For example, IIS contains Web Sites, which hold web pages. In SharePoint, IIS
Web Sites are considered to be web applications and contain web pages organized into sites
and subsites, called site collections . SharePoint web applications are considered containers
and security boundaries for those site collections, largely because of the built-in
properties of IIS Web Sites and their management (for example, specifying application pools and
whether anonymous access is allowed). Those settings may be configured in SharePoint but
are applied to the IIS Web Site (aka web application). This explains why anonymous access is
enabled at the web application level and then trickles down to each site collection contained
within. The IIS server role must be installed before SharePoint can be installed. An additional
SharePoint feature that depends on IIS is incoming email, which requires that the SMTP
service be enabled in IIS.
Database SharePoint obviously requires a database on the back end in order to store data.
Currently, SharePoint only supports SQL Server for its content and configuration databases
(although external data can be accessed from other types of data sources in other ways).
SQL Server SharePoint Foundation requires the 64-bit version of either SQL Server
2005 SP3 with Cumulative Update (CU) 3, SQL Server 2008 SP1, CU2, or SQL Server
2008 R2. This pricey SQL package is a database powerhouse. Network-aware, it can be
made to support clustering and more. It is ideal for handling the huge amounts of data
a large server farm might generate. It can also be clustered for failover scenarios (which
SharePoint can support). SQL Server is possibly overkill for small offices that are
considering SharePoint. However, if you already have SQL Server 2005 SP3 CU3, 2008 SP1, CU2,
or SQL 2008 R2 on your network, then by all means use it.
SQL Server 2008 Express If you don’t have SQL handy (and don’t want to shell out
the cash to install and use it), you can do the poor man’s single SharePoint server install,
as discussed in Chapter 2, “Installation Standalone.” This will install SQL Server 2008
Express during SharePoint’s initial setup. SQL Express is a free, local-only database
(meaning that it cannot be remotely accessed). With SQL Express, SharePoint can create
and manage its databases just fine. The catch is that the Express version of SQL cannot
support any other SharePoint servers accessing it and has a hard database size limit of 4
GB (you can upgrade it SQL Express 2008 R2, which can support 10 GB after install). It is
not as robust as its big brother SQL 2008, and it has no graphical tools built in with which
to manage and update it. The previous version of SharePoint used a different kind of
single-server database engine, which had no database size limitations.
If you are considering upgrading to SPF from WSS 3.0 and you have a basic or single server
installation, you will need to do a few extra things to prepare for the upgrade because of this database
version change. See Chapter 15, “Migrating from WSS 3.0 to Windows SharePoint Foundation 2010,”
for details.
