Whether a customer is a large enterprise or a small company, the key features of Reporting
Services that are always available include the following:
- Manageability: Reporting Services is easy to deploy and manage. In addition to having a convenient web-based management interface, both deployment and management of Reporting Services can be scripted.
- Security: Reporting Services keeps corporate data secure. Reports and information are not accessible, unless sufficient privilege is granted to a user.
- Programmability: Reporting Services allows developing of a custom functionality that can be embedded in a report, called from a report, or scripted.
- Reporting controls and wizard: Windows and web-based ReportViewer controls are supplied with Visual Studio 2008. Report controls simplify adding reporting functionality to Windows and web-based applications.
Additional features available in the Standard Edition of Reporting Services include the following:
- Extensibility: Reporting Services allows adding new server functionality. RDL is an XML-based language and is designed to be extensible. SSRS also allows for extending data-processing, data-rendering, and data-delivery extensions with your own custom implementations.
Additional features available in the Enterprise Edition of Reporting Services include the following:
- Scalability: Reporting Services Enterprise Edition supports large workloads and high volume reporting. Support for web farms in Enterprise Edition allows easy scale out, providing an ability to add extra capacity as needed. In addition, Enterprise Edition scales up, supporting more than two CPUs.
- Availability: Web farm support of Reporting Services Enterprise Edition paired with the Reporting Services catalog installed on a SQL Server 2008 cluster enables high availability reporting solutions.
- Data-driven subscriptions: Reporting Services Enterprise Edition allows customers to dynamically change the recipient list, report parameters, and processing options. In contrast, Standard Subscription, available in Standard Edition of Reporting Services, is for a single predefined user and single predefined parameter set.
To help determine the most appropriate version, refer to Table 5.7 to review key features
of SSRS editions.

Developer and Evaluation editions have the same capabilities as the Enterprise Edition of SSRS. However, the Developer Edition is licensed and supported only in the development environment, and the Evaluation Edition expires after 180 days.
In a "nutshell," a server license (for Workgroup, Standard, or Enterprise editions) is required for every operating system environment on which that edition of SQL Server software or any of its components (for example, Reporting Services) is running.
This means that a company does not have to buy a separate license if SSRS is installed with SQL Server 2005 together on a single computer. For scale-out (web farm) deployments, each web server that runs Report Server must have a SQL Server license.
In this chapter, you learned about various SSRS deployment choices. Deployment choices for SSRS components range from a developer's workstation, in which all SSRS components are installed on a single computer, to an enterprise high-availability and high-performance multiserver web-farm deployment.
This chapter also discussed SSRS deployment options for Internet access, and examined the hardware and software requirements, licensing, and key features of the various SSRS editions.
The next chapter delves into the SSRS installation process.
