and compiles the .aspx page.
The server then invokes the proxy (which is instantiated
in the .aspx page) to call the Web Service. The protocol
used here is XML Protocol (XMLP). XMLP was
formerly known as Simple Object Access Protocol
(SOAP).
The response is then sent back to the client in a format
that the client .aspx page can use. The proxy carries out
the data translation.

Module Strategy
Use the following strategy to present this module:

Overview of the .NET Enterprise Servers
Introduce the concept of the .NET enterprise-level servers from Microsoft.
Discuss the role of each product as described in the module, but remember
to stress the importance of the functions with respect to e-business
applications.
Focus on only the features described in the module—each product provides
many more features, but the ones covered in this module are the important
ones for describing the role of each product in e-business .NET solutions.

Overview of the .NET Framework
Focus on the Web Services and ASP.NET at an overview level. Ensure that
the students understand that they will develop their e-business applications
to take advantage of many of the features in the .NET Framework.
Use the information on Web Services, ADO.NET, and ASP.NET to
familiarize the students with these technologies and help them understand

In this module, you will be introduced to the new Microsoft
®
.NET Enterprise
Servers. You will see how each of the servers contributes to the implementation
of business-to-consumer (B2C) and business-to-business (B2B) e-commerce
solutions.
You will also learn about the Microsoft .NET Framework, including ASP.NET
and Web Services. Finally, the module provides an overview of the .NET
Framework software development kit (SDK), which provides the tools for
building .NET applications.
After completing this module, you will be able to:

Identify the role of each of the .NET Enterprise Servers in e-business
solutions.

Describe the .NET Framework.

Identify the role of Web Services.

Describe the .NET Framework SDK components.

The .NET Enterprise Servers work together to provide the infrastructure and
full functionality for your e-business solutions. As such, each of the .NET
Enterprise Servers plays a specific role in e-business solutions.
The .NET Enterprise Servers consist of:

Enterprise Servers in the context of an e-business infrastructure around which
you will build your e-business solutions.
The key roles played by each .NET Enterprise Server are summarized as
follows:

ISA Server 2000 provides a secure, optimized gateway between your
company’s network and the Internet.

Application Center 2000 provides management and scalability for your
e-business applications.

Commerce Server 2000 provides B2C functionality and in-depth analysis
features for your e-business data.

SQL Server 2000 provides the Web-enabled, high performance Relational
Database Management System (RDBMS) needed by your e-business
applications for data storage and management.

BizTalk Server 2000 provides Extensible Markup Language (XML) data
manipulation capabilities, in addition to integration with your trading
partners’ systems.

Exchange 2000 Server provides messaging and collaborative support for
your e-business solutions.

ISA Server 2000 works together with Internet Information Services (IIS) Web
servers to provide access to the Internet.
ISA Server is the next step in the evolution of Microsoft Proxy Server 2.0.
You can use ISA Server to provide secure, reliable, and high-performance
access to your e-business solutions for both your trading partners in your B2B
solutions and your customers in your B2C applications. In addition, you can use
ISA Server to provide Internet access to your employees.


Prevents unauthorized access to a network by applying security templates to
your operating system.ISA Server provides protection against unauthorized
access and hacker attacks. ISA Server and Windows 2000 work together to
lock down your system and network against unauthorized access. This is
easily achieved by the application of pre-defined security templates to your
operating system.
Common network attacks, such as port scanning, can be identified and
responded to in order to help prevent hacker attacks.

Fast Web Access
Apart from providing security, the ISA Server also provides caching
mechanisms and scheduled download features to accelerate the performance of
your e-business solutions.
ISA Server:

Provides high performance caching of Web pages.
It implements fast random access memory (RAM) caching of Web pages
that can be served to the browser directly. In addition to the RAM cache,
ISA Server also implements a highly optimized disk cache for Web pages,
thereby providing more storage capacity for the caching engine of the
server.

Schedules downloading of content.
In a scenario in which your e-business solution has multiple servers

Application Center 2000 provides application management, application
scalability, and application availability features. These features enable both
administrators and developers to develop, deploy, and operate scalable, reliable
applications, without requiring them to have in-depth knowledge of the
functioning of the application in a high-availability and scalable environment.
Although this applies to traditional line-of-business applications that your
enterprise may develop, it also holds true for your B2C and B2B e-commerce
applications.
Application Management
Your Web-based e-business solutions are likely to be implemented on a high-
performance, distributed application architecture. The fact that many different
computers house many different layers and components can present challenges
for both the developers and the administrators of your e-business solution.

Software Scalability
Clustering together multiple application servers has been a popular approach to
increasing both application scalability and application reliability in recent years.
Clustering allows for application load balancing and fault tolerance.
Application servers that are clustered appear as a single unit to client machines
and administrators alike. There are two types of clustering you can use to
achieve these benefits:

Hardware clustering
Hardware clustering involves specialized servers and cluster controllers to
provide the clustering functionality. This tends to be an expensive solution
when compared to software clustering.

Software clustering
The software-clustering capability of Application Center 2000 provides the
traditional clustering benefits while being a much more cost-effective
solution.
Application Center 2000 software clustering integrates with Windows 2000
Network Load Balancing (NLB). NLB provides a way to configure several
physical machines to appear to clients as one logical server. Windows 2000
incoming requests are directed to an Internet Protocol (IP) address that
identifies this virtual server and the NLB service distributes the requests
evenly among the actual physical servers in the cluster. Because the service
runs on each member of the cluster, there is no single point of failure, and if
one member of the cluster becomes unavailable, the requests are distributed
among the remaining servers.
In addition, Application Center 2000 software clustering integrates with
COM+ component load balancing, thereby allowing the distribution of

Business Pipelines
Commerce Server 2000 includes customizable order processing pipelines (OPP)
for B2C applications.
The pipelines control the flow of transactions for your customer-purchase
operations. You can customize the pipelines to add your own stages to the
business process or to modify the functionality and sequence of the existing
stages.

OPP is part of Commerce Server 2000; however, commerce interchange
pipelines (CIP), which were available in the earlier versions of Commerce
Server, are not present in Commerce Server 2000. BizTalk Server 2000
includes tools that enable commerce interchange.

Catalogs
The catalog functionality of Commerce Server 2000 allows you to implement
effective management systems for millions of products and services.
