Lesson 6  – Deploying Applications ITMT 2456 70-647 Plan for application delivery. Planning network and application services 1.3 Plan for Terminal Services. Planning network and application services 1.4

Selecting a Windows Server 2008 R2 Edition always, the first step in any large scale deployment project is planning. You must decide which applications your users will need and how you intend to deploy them. our servers, and your workstations are already in place.

Identifying User Requirements For enterprise administrators to provide users with work stations, they must determine what tasks the users have to accomplish.

To create workstation configurations, administrators must know the hardware and software requireme nts for each application a user workstation must run.

Fat Clients Most enterprises use fat clients to support applications on their workstations.

user needs locally.

Thin Client A thin client, by contrast, is a computer that functions as a terminal for applications running on servers.

on another computer and carry the user’s mouse and keyboard input from the workstation to the applications.

Remote Desktop Services (RDS) Windows Server 2008 R2 includes R emote Desktop Services (RDS), which provide presentation virtualization capabilities in a number of permutations.

Choosing a Deployment Method In most enterprise environments, the object is to create a series of uniform workstation configurations, to facilitate maintenance and troubleshooting later.

workstation of the same type.

Installing Applications Manually The simplest type of application deployment is the same one that individuals use for their home systems: manual installation to the computer’s local hard disk.

-based installation program that is easy to use and provides customizing options.

Deploying Applications Using Group Policies One method of automating application deployment using only the infrastructure supplied by AD DS is to use the Group Policy Software Installation settings.

Deploying Applications Using Group Policies Group Policy objects have two Software Installation nodes, one under Computer Configuration and one under User Configuration.

or users receiving the GPO. Depending on the settings you select when you add the package, the target computers can deploy the software in one of three ways, as follows:  – When you assign a package to a computer, an automated software installation occurs as soon

as the system starts and downloads the GPO.  – When you assign a package to a user, the policy adds the application to the computer’s Start menu, and can associate certain file name extensions with the application’s executable. The installation occurs when the user

launches the application from the Start menu for the first time or opens a file associated with the application Publish – When you publish a package to a user (you cannot publish to a computer), the policy adds the application to the Get Programs control panel in Windows 7 or Windows Server 2008 R2 (or the Add or Remove Programs control panel in earlier versions), enabling the user to install the application on demand at any time.

Deploying Applications Using System Center Configuration Manager System Center Configuration Manager (SCCM) 2007 is a Microsoft network management product that provides administrators with a variety of valuable functions, not the least of which is so ftware deployment. rchase the software separately. SCCM deploys software using packages, just as Group Po licy does, but the packages themselves are o f a completely different format than the Windows Installer packages Gr oup Policy uses. ration Manager console, which is the tool you use to create your own packages.

Using Web-based Applications An increasingly popular alternative to locally-installed applications is the use of web servers and web browsers as the components of a client/server application.

response to their requests. Internet Information Services (IIS) version 7, included with Windows Server 2008 R2, has role services that support a variety of application development environments, some venerable and others quite recent, including the following:

(ISAPI)

IIS is designed to support multiple web sites and multiple applications, and it does so by isolating application functions in separate address spaces called application pools. sion within IIS that consists of a r equest queue and one or more worke r processes. A worker process is a host for user-developed application code, which is responsible for processing requests it receives from protocol listeners – modules that wait for incoming client re quests – and returning the results to the client.

process running outside of that pool. This is known as worker process isolation mode.

Remote Desktop Services Remote Desktop Services (RDS) is a role that enables a server running Windows Server 2008 R2 to host applications and entire desktops for multiple clients all over the network. e actual application computing; the clients function only as terminals.

Remote Desktop Advantages Reduced client hardware requirements

licenses

Remote Desktop Infrastructure All client/server applications, by definition, require three basic elements:

Remote Desktop Session Host A role service that runs on a computer running Windows Server 2008 R2, which enables multiple clients to connect to the server and run individual desktop or application sessions.

Remote Desktop Connection Client A program running on a workstation computer, which est ablishes a connection to an RDS server using RDP and displays a session window containing a desktop or application. All Windows versions include the Remote Desktop Connection client program.

Remote Desktop Protocol (RDP) A networking protocol that enables communication between t he RDS server and the client.
