Chapter 6: Capacity and Deployment Planning
The following sections outline the core deployments and describe the progression from a single-server
topology to a multiserver topology. The deployments noted here provide an opportunity to discuss the
differences between the deployment types, but they don’t represent a finite set of the allowed
topologies. The actual topology you end up with may be a hybrid of a farm type discussed in this chapter.
One valuable point to take away is that you can scale a MOSS deployment in different ways to meet
your specific needs for Excel Services.
Different terms are used when referring to a single-server topology. An evaluation server and a standalone
server both refer to a single-server topology. In this topology, a single server supports all three roles, and
all MOSS components are installed on a single computer. For Excel Services, this includes both the Excel
Services front-end web components and the application server Excel Calculation Services (ECS)
components. The SQL Server Express Edition of SQL Server 2005 is installed on the machine, and the
configuration and content databases reside on the server. Installing an evaluation server is discussed in Chapter 2.
Figure 6-1 shows a single-server topology.
You cannot add more MOSS servers to this deployment. The single server is all you get with this topology,
and there will not be any opportunity to scale this farm out by adding servers to take on any of the roles,
like Web Front-End (WFE) or application server. If there is even the chance that scaling out is a possibility
in the future, then consider starting with a small farm topology (discussed later in this chapter).
This topology is the easiest and quickest way to install and get Excel Services up and running. This type
of deployment is also referred to as a one-click install because it really doesn’t require much effort to get it
installed and working. Excel Services is configured right out of the box to load workbooks, whereas all
other types of deployments require additional post-setup steps to enable Excel Services to load workbooks.
