Multimedia Presentation
This section provides multimedia presentation procedures that do not fit in the
margin notes or are not appropriate for the student notes.
Web Services Execution Model
Present the animation titled “Web Services Execution Model” by using the
instructions provided in the following table.
Action Say this

There are two ways of calling a Web Service: directly
from the browser or by using a proxy client. This
animation demonstrates these two ways of calling a Web
Service.
Click Direct Client To access a Web Service directly from a browser, the
client simply specifies the Uniform Resource Locator
(URL) to the Web Service (.asmx file). The protocol used
here is Hypertext Transfer Protocol (HTTP).
After processing the request, the server returns a
description page to the client that lists all of the available
methods of the Web Service requested by the client.
After the client discovers the methods of the Web
Service, it invokes a particular Web Service method.
The server processes the request and returns the data to
the client in the Extensible Markup Language (XML)
format.
Click Proxy Client Another method of calling a Web Service is to use a
proxy client. In this method, the client issues a request to
the server for a Web Service. The request is in the form
of an .aspx page.
On receiving the request from the client, the server parses

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.

*****************************
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.
Secure Internet Connectivity

The security and firewall features of the ISA Server provide a manageable and
secure mechanism for allowing customers and trading partners to access your
e-business solutions.
ISA Server:

Provides firewall protection at the circuit, packet, and application levels.The
firewall capabilities allow you to screen Internet traffic not only at the
circuit and packet level, but also at the application level. This allows you to
secure your Internet gateway for use by only approved applications.

Allows access to a virtual private network (VPN) by integrating with
Windows 2000.
Your trading partners can access your B2B application functionality through
the secure remote access functionality of a Windows 2000 VPN.
Topic Objective
To discuss the role of the
ISA Server 2000 in
e-business.
Lead-in
ISA Server is Microsoft’s
new enterprise firewall and
Web caching server built for
Windows 2000 Server.
Delivery Tip

e-business solutions are
more important for this

module than specific
technical details.
Module 3: Microsoft .NET Enterprise Servers, Framework, and Development Tools 5


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
participating in the caching and optimization of performance, ISA Server

allows you to distribute content between the servers and then pre-load the
cache. You can easily manage both the distribution of content and pre-
loading of the cache on each ISA Server by setting up a schedule for these
actions.

The cache engine of ISA Server is also fully programmable through the caching
application programming interface (API). This API allows you to write
additional performance-enhancing utilities as part of your e-business solution.

You will learn more about caching in ISA Server in Module 4,
“Designing the Client Experience,” in Course 2260A, Designing E-Business
Applications with Microsoft .NET Enterprise 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.
Application Center 2000:


Reduces management complexity.
It presents your entire application as a single entity, thereby reducing the
complexity involved with distributed e-business solutions.

Synchronizes application over the servers in a cluster.
In addition to designing multiple layers in your application architecture, you
can also implement your solution in a clustered environment. Application
Center 2000 enables the synchronization of configuration settings between
all machines in a cluster, thereby allowing you to easily keep your content
and settings consistent across all the machines in a cluster.

Topic Objective
To discuss the role of
Application Center 2000 in
e-business.
Lead-in
Application Center 2000 can
be used to simplify the
management and
monitoring of large,
clustered applications.
Delivery Tip
Focus your delivery on
Application Center 2000 in
the context of e-business
solutions. Features that
enhance e-business
solutions are more important
for this module than specific
technical details.

Module 3: Microsoft .NET Enterprise Servers, Framework, and Development Tools 7

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

component execution across multiple servers. The advantages of component
load balancing for distributed computing are similar to that of the NLB.
However, it is not simply a matter of redirecting incoming requests to
available members of the cluster, but rather the distribution of object
instances across the network to make the best use of available processing
power.

Mission-Critical Availability
Application Center 2000 is designed such that any single server can be taken
offline, either for maintenance or when caused by a power outage, without
affecting the availability of the e-business solution functionality to the client.
The effect of this is that your e-business solutions can have 24x7 (unlimited)
availability by using standard off-the-shelf servers. The 24x7 availability
concept is of utmost importance for your e-business solution.
You must aim to provide access to your e-business solutions at any time for
both your customers and trading partners because they may be in different time
zones than yours. This mission-critical availability is easily attained by using
Application Center 2000, while also reducing your implementation and running
costs at the same time.
Delivery Tip
Emphasize that Application
Center 2000 integrates with
Windows 2000 software
clustering.

Module 3: Microsoft .NET Enterprise Servers, Framework, and Development Tools 9

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.

Commerce Server supports product search capabilities. Customers can find
product information easily and efficiently with the help of catalogs. Commerce
Server 2000 translates any catalog-related query it receives to a database query,
which it will then issue against the RDBMS.
Customization of catalogs
It is likely that you need to categorize products into some sort of hierarchy that
reflects the relationship between products. The Commerce Server 2000 catalog
system allows you to define such hierarchies and design your own categories.
This means that you can completely customize the catalog system to match the
products and services that you provide to your customers and trading partners.
Profile System
Commerce Server 2000 includes a profiling system for handling different
categories and profiles of your customers and trading partners. Profiles are data
definitions for common business entities. Commonly profiled entities include:

Users

Organizations

Purchase orders

Requisitions

Products

Accounts

Profiles are easily created and extended by using the Microsoft Management
Console (MMC) snap-in for Commerce Server 2000. Profiled entities can be
aggregated across multiple stores, thereby allowing you to define the profiled

object once for your e-business application. Profile attributes can be stored in
any of several data stores and then presented to the application as a single
profile object. Commerce Server 2000 Profile System has out-of-box support
for the Active Directory
™
directory service in Windows 2000 and SQL Server
definition storage. Other stores, such as DB2 and Oracle, can be implemented
using the Commerce Server 2000 SDK.
Delivery Tip
Explain the concept of
pipeline diagrammatically.
