What Is IPD?Guidance that clarifies and streamlines the planning and design process for Microsoft® infrastructure technologies

IPD:• Defines decision flow

• Describes decisions to be made

• Relates decisions and options for the business

• Frames additional questions for business understanding

IPD guides are available at www.microsoft.com/ipd

Getting Started

Internet Information Services 7.0 and Internet Information Services 7.5

Purpose and Overview

Purpose• To provide guidance for designing an Internet Information

Services (IIS) infrastructure

Overview• What’s new for Windows Server® 2008 R2 and IIS 7.5

• IIS infrastructure design process

• Assessing the applications

• Designing the IIS

What’s New in Windows Server 2008 R2 (IIS 7.5)

The following changes are available in the Web Server (IIS) role in Windows Server 2008 R2:• Integrated extensions

• Management enhancements

• Application hosting enhancements

• Enhancements to Microsoft .NET Framework support on Server Core

• BranchCache®

IIS Decision Flow

SCM ITAMAP

w/ CAL Tracker

Step 1: Determine the Project Scope

• Task 1: Create a Site List• Determine what is in scope: a single application, a web farm, a

department, a site, or any other logical collection that has a clear boundary

• The steps in this guide are designed to be performed once per collection or site

Step 2: Characterize the Applications

• Task 1: Create an Application Inventory

To gather requirements, ask the following:

• Will it need Microsoft .NET Framework?

• Does it need to be isolated?

• How many users will need to gain access?

• What are the fault-tolerance needs?

• Is the full list of information needs in the guide?

Step 3: Determine Windows Server 2008 Edition and Installation Mode

• Task 1: Determine the Edition

• 32-bit (Windows Server 2008)

• 64-bit (Windows Server 2008 or Windows Server 2008 R2)

• Task 2: Determine the Installation Mode

• Full installation (Standard/Enterprise/Datacenter)

• Server Core installation

Step 4: Determine the Location for Configuration and Content Storage

• Task 1: Determine the Configuration and Content Location• Local storage• Remote file shares

• Task 2: Determine the Configuration and Content Storage Requirements• Capacity• Performance

• Task 3: Determine the Configuration and Content Storage Fault Tolerance• Built-in (network-attached)• File replication• Server clustering

Step 5: Determine the Fault Tolerance for the Infrastructure

• Task 1: Determine the Fault-Tolerance Approach• Software-based network load balancing (NLB)• Hardware load balancers• Application Request Routing

• Task 2: Determine the Need for Additional Services• Additional services like Domain Name System (DNS) may require

fault tolerance as well

Step 6: Determine Required Server Resources

• Task 1: Determine Whether to Use Virtualization• Physical hardware• Virtual machines

• Task 2: Define the Number of IIS Instances

• Task 3: Server Scaling Considerations

• BranchCache (new for Windows Server 2008 R2)• CPU• Memory• Network

Summary and Conclusion

• Each application was scoped and characterized

• Implementation method and platform selected

• Configuration and content storage location decided

• Fault-tolerance needs addressed

• Server instances determined and scaled appropriately

• Provide feedback to ipdfdbk@microsoft.com

Addenda• Benefits of using the IIS guide

• IPD in Microsoft Operations Framework 4.0

Benefits of Using the IIS Guide

• Benefits for Business Stakeholders/Decision Makers

• Most cost-effective design solution for implementation

• Alignment between the business and IT from the beginning of the design

process to the end

• Benefits for Infrastructure Stakeholders/Decision Makers

• Authoritative guidance

• Business validation questions ensuring solution meets requirements of

business and infrastructure stakeholders

• High integrity design criteria that includes product limitations

• Fault-tolerant infrastructure

• Proportionate system and network availability to meet business requirements

• Infrastructure that’s sized appropriately for business requirements

Benefits of Using the IIS Guide (Continued)

• Benefits for Consultants or Partners

• Rapid readiness for consulting engagements

• Planning and design template to standardize design and peer reviews

• A “leave-behind” for pre- and post-sales visits to customer sites

• General classroom instruction/preparation

• Benefits for the Entire Organization

• Using the guide should result in a design that will be sized, configured,

and appropriately placed to deliver a solution for achieving stated business

requirements

IPD in Microsoft Operations Framework 4.0

Use MOF with IPD guides to ensure that people and process considerations are addressed when changes to an organization’s IT services are being planned.
