2. Module Overview
Deploying a Web Application

3. Lesson 1: Deploying a Web Application
16: Deploying ASP.NET MVC 4 Web Applications
Demonstration: How to Create a Windows Azure Website

4. ASP.NET MVC 4 Dependencies
16: Deploying ASP.NET MVC 4 Web Applications
ASP.NET MVC 4 dependencies include:
The ASP.NET Framework 4.0 Common Language Runtime (CLR)
The MVC 4 runtime
A Database server
Entity Framework
Membership Providers
Question: Why should we use specific mapping for IIS 6.0 or earlier or IIS 7.0 in classic mode?
Answer: We should use specific mapping for IIS 6.0 or earlier, because these versions of IIS are not configured to route all request to ASP.NET engine.
You can mention that mapping all requests to ASP.NET engine is a good approach, because it will not require changes to applications. This approach eliminates the need to retest the application.
Different techniques for deploying such dependencies are covered later in this module.

5. Deploying Web Applications to Single Server Farms
16: Deploying ASP.NET MVC 4 Web Applications
To deploy an application on a single server farm:
Set up the web application in IIS
Configure application pools
You can run many applications in the same application pool
You can install an application in a specific isolated application pool
Copy the web application files to IIS
Question: What is the purpose of configuring additional application pools?
Answer: Configuring additional application pools allow different application configurations, such as user accounts.
You can use a dedicated application pool for each application to allow dedicated IIS process to handle requests for different application to increase redundancy.
Using the Visual Studio deployment tools to copy web application files to an IIS web server is covered in detail, in Lesson 2.

6. Deploying Web Applications to Multi-Server Farms
16: Deploying ASP.NET MVC 4 Web Applications
Characteristics of deploying applications to multi-server farms:
Multi-server web farms help increase performance, resilience, and reliability
It has greater capacity than a single server farm
To deploy your web application to a multi-server farm:
Create IIS applications and application pools on each server
Create a matching IIS configuration on each server
Use external hosted session state or session affinity
Configure machineKey element in the web.config file
Question: What is the purpose of configuring the machineKey element in the web.config file?
Answer: Configuring the machineKey element ensures that the same key is used for encrypting and decrypting content stored in the session state or configuration file.

7. Deploying Web Applications on Windows Azure
16: Deploying ASP.NET MVC 4 Web Applications
To deploy an application on Windows Azure:
Create a new web application in the Windows Azure management portal
Download a publishing profile
Start the Publish wizard and import the publishing profile
Configure connection strings
Observe that Microsoft Visual Studio publishes the web application on Windows Azure
Question: How does Windows Azure cloud services help enhance the flexibility of the application?
Answer: Windows Azure cloud services help separate user interface logic that you build in a web-role project, from business logic that you build in a worker process project. This separation provides greater flexibility, and it enables calling the business logic from other processes, such as mobile applications.
You can use Microsoft Visual studio to deploy applications to Windows Azure. However, to avoid accidental deployment to Windows Azure, you may wish to avoid using Microsoft Visual Studio for deployment. Instead, They use service packages, since they provide more control over the deployment process.

8. Reviewing Configuration for Production
16: Deploying ASP.NET MVC 4 Web Applications
While reviewing the configuration for production:
Include the transformation elements in the following web.config transformation files for generating resultant web.config files:
Web.release.config
Web.debug.config
Modify the web.config file by using the debug, xdt:Transform, and Insert attributes
Question: How can you configure the web.config file for publishing to a production environment, without using web.config configuration files?
Answer: You can edit the web.config file manually. Such a configuration will apply to production, debug and other configurations.
You can add additional web.config transform files for use in different configurations.

9. Deploying to Windows Azure
16: Deploying ASP.NET MVC 4 Web Applications
In the next demo, you will show the students how to publish an ASP.NET MVC web application to such a website for production.
Preparation Steps
