Overview of .NET Enterprise Servers
By William J. Harding
The Microsoft family of .NET Enterprise Servers provides the enterprise business with a secure, scalable, and a high-performance platform on which to build integrated business software solutions. This chapter provides an overview of the Microsoft .NET Enterprise Server family of products, including:
- Microsoft Application Center 2000
- Microsoft BizTalk Server 2002
- Microsoft Commerce Server 2002
- Microsoft Content Management Server 2001
- Microsoft Exchange 2000 Server
- Microsoft Host Integration Server 2000
- Microsoft Internet Security and Acceleration (ISA) Server 2000
- Microsoft SQL Server 2000
- Microsoft Mobile Information 2001 Server
- Microsoft SharePoint Portal Server 2001

Application Center 2000
Organizations use Microsoft Application Center 2000 to deploy and manage applications. An Application Center 2000 application is a group of components that together make up a complete, distributed business solution. These components can include Web sites, COM+
-
Load balancing.
Application Center 2000 includes two software load balancing technologies that work with stateless middle-tier components, such as Web sites and COM+ applications. Network Load Balancing (NLB) balances IP
requests across a cluster of servers on the Webtier , which serves HTTPclients . Component Load Balancing (CLB)balances the activation of DCOM requests, which serves DCOM traffic on the business logic tier.Application Center 2000 is also compatible with other load balancing devices and does not require a shared disk or special hardware. An Application Center 2000 cluster can serve intranet or Internet clients running thin-client software, such as Web browsers, or thick-client applications such as Microsoft Visual Basic programs.
Application Center 2000 clusters are not the same as clusters created with Microsoft Windows Clustering. The Windows Clustering model is designed to handle back-end applications, such as Microsoft SQL Server 2000 databases or Microsoft Exchange 2000 Server stores; Windows Clustering uses a shared disk resource to coordinate between cluster
members . -
Centralized management.
The Application Center 2000 Integrated Management Console provides administrators with a single, unified image of the components that are deployed throughout a cluster. Specifically, administrators can use the Application Center 2000 management snap-in to configure load balancing, add and remove members, or configure a member to go offline when an application-level failure occurs. (Application Center 2000 monitoring tools detect hardware and software failures automatically and can trigger actions, such as running scripts or sending e-mail notifications, in response to a failure.) Administrators also have the option of managing Application Center 2000 clusters remotely through a browser or with a command-line tool.
Administrators can construct logical views of the applications and components deployed throughout a cluster and then manage them from a single location. Application Center 2000 can also provide cluster-wide views of performance trends, simplifying event management. Once an administrator defines an application, Application Center 2000 can keep the contents of that application synchronized across a cluster.
- Software scaling. Administrators can add members to and remove members from Application Center 2000 clusters without interrupting Web site availability. The deployment capabilities of Application Center 2000 enable administrators to use a staging server as a central content store from which to deploy applications to new servers within a cluster or to new clusters.
The following illustration highlights the load balancing, management, and software scaling capabilities of Application Center 2000.
