The chapter discusses some of the tools currently available and some that are coming soon from Microsoft that are intended to work hand-in-hand with Microsoft Operations Manager (MOM) 2005. Many of these tools can greatly improve the ability to manage and defend an enterprise from a variety of issues, starting at the design phase all the way through implementation. There are few things that need to be remembered with the System Center tools. Not all tools are currently available, and features in the beta versions may not carry over to the full release. Systems Management Servers (SMS) 2003 is the most senior of the System Center tools, and therefore is the most robust with the possible exception of MOM 2005. Each tool should be used as only one piece of a much larger system and network architecture design. It assists you reduce your administrative burden while increasing your ability to understand the running of the machine. System Center is being deployed by Microsoft in a wave approach, meaning that different applications will be released over a number of years. However, beta versions are currently available, and can be downloaded and reviewed to determine if they may be a good fit for your organization.
