Web Services Execution Model

Present the animation titled “Web Services Execution Model” by using the instructions provided in the following table

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

*****************************I LLEGAL FOR N ON -T RAINER U SE *****************************

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

ISA Server is Microsoft’s

new enterprise firewall and

Web caching server built for

Windows 2000 Server

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,

Mission-Critical Availability

*****************************I LLEGAL FOR N ON -T RAINER U SE *****************************

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 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:

high-
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

Application Center 2000 can

be used to simplify the

the context of e-business

solutions Features that

enhance e-business

solutions are more important

for this module than specific

technical details

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

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:

Business Analysis

Strategic decision makers need timely access to product data, time data, location data, and other indicators of how well your business is performing This data has only one logical source—your business transaction information That is, on a daily basis, your e-business solutions function primarily as a data-capture and transaction-control system This data often provides the basis for decision support systems

Usually, the persistent data storage is implemented through an RDBMS for space efficiency and transaction-processing efficiency However, the format and structure of this data rarely matches that which is optimally designed to support the strategic decision-makers needs For example, the RDBMS contains very detailed information about each order that has been processed The strategic decision makers do not typically require this level of detail They are usually more interested in aggregations of data, such as total sales for a particular product, total sales in September 2000, or total sales in the Northeast region Commerce Server 2000 includes tools that allow business managers to base their decisions on this type of appropriate data aggregations

*****************************I LLEGAL FOR N ON -T RAINER U SE *****************************

Commerce Server 2000 allows your business managers and Information Technology (IT) professionals to work together to enhance your e-business solutions It enables the analysis of business data, which is generated from the transactions with your users, to improve users’ experience with your e-business site on their next visit

Closed-Loop Analysis

Closed-loop analysis is the process of analyzing data from one or more transactions to actively promote the next business transaction At the end of the subsequent transaction, the data from that transaction is incorporated into the analysis process to further promote yet another transaction The net result is that each transaction's data can be analyzed and used to continue the cycle and support your company's sales effort

E-business solutions lend themselves extremely well to this type of analysis and consequent promotion The key part that lends this type of e-business solution

to closed loop analysis is that all data is in an easily manipulated electronic format

Scenario

Consider the following scenario:

1 A user browses your product catalog or buys a product

You have access to this information through the transaction processing system or the Web server's log

2 You import this data into your data warehouse or data mart

You can automate this process with Microsoft's Data Transformation Services (DTS)

Topic Objective

To explain how the

closed-loop analysis process

works

Lead-in

Closed-loop analysis is a

process of analyzing data

from one business

transaction to the next

and explain each step of the

closed-loop analysis cycle

DTS is a tool that ships with SQL Server 2000 It allows you to transfer and transform data from any OLE DB store to any other OLE DB store The transformation capabilities of DTS make it an ideal product for populating a data warehouse or data mart

3 You use Business Desk and Analysis Services to analyze this data and provide useful profile information about the product, customer, or the B2B trading partner

Analysis Services allows you to store data in a multidimensional

format, known as a cube Commerce Server 2000 uses this format as the

basis for its Business Desk analysis

4 You convert the results of your analysis into a targeted advertising campaign for the profiled user, organization, or product

The results of this analysis may be the decision to cross-sell a related product based on the product profile, or it may be the decision to discount other products that a user typically purchases based on the user profile The results may be a combination of analyses from many different types of profiles, so that up-sell or cross-sell can be targeted to a highly focused combination of organization, customer, and product line

5 Users visit your site frequently because the site is personalized to cater to the preferences and needs of each user

Users will continue to use your e-business site because it offers them useful, targeted information and perhaps discounts or promotions on the products and services in which they are interested This in turn leads to more traceable data that you can put directly into your analysis system

With multiple iterations through this closed loop, the customer receives a more useful, targeted Web experience and your business analysts gain a lot of useful information for analysis

SQL Server 2000 is an industrial-grade RDBMS It provides high-performance data access, data management, and data storage for your e-business

applications

E-Commerce and Line of Business

SQL Server 2000, as a RDBMS, provides the security, optimized storage, integrity checks, and data transaction–processing capabilities you need for your enterprise and e-business applications Specific features introduced in

SQL Server 2000 make it a compelling choice for use as both a B2B and B2C database server These features include:

Rich XML support, for integration with other NET Enterprise Servers and with your customers and trading partners

Direct Web access to your data, for ease of development

Distributed partitioned views, for scalability and high performance

Stability, to enable 24x7 access to data

In addition, SQL Server 2000 supports the concept of multiple instances, thereby allowing multiple installations of SQL Server 2000 on the same machine Therefore, unlike the earlier versions of SQL Server, with SQL Server 2000, you can have many instances of it running on the same machine Each installation (in the same computer) can retain its own configuration options (such as character sets, sort orders, and administrative

accounts) per instance This is extremely useful in situations in which one
