Internet Information Services 7.0 and Internet Information Services 7.5 Infrastructure Planning and Design Published: June 2008 Updated: November 2011

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

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 Whats new for Windows Server ® 2008 R2 and IIS 7.5 IIS infrastructure design process Assessing the applications Designing the IIS

Whats 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 SCMITA MAP 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

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 thats 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 organizations IT services are being planned.
