This document discusses building services on Microsoft Azure. It provides an overview of Azure cloud architecture, including services, roles and instances. It describes the process of packaging and deploying Azure services, including defining roles and configurations. Debugging, testing locally using emulators, and updating configurations in Azure are also covered. The document uses a conceptual "Best Man" wedding management application to illustrate key Azure concepts.

3. Agenda
• Why Cloud?
• Azure Cloud
• Services, Roles and instances
• Packaging and Deployment
• Testing and Debugging
• Configurations

4. Why Cloud?
A Game Changing Technology
•Infinite shared resources & services
– Infrastructure is not a limiting factor
– No need to equip for peak-load requirements
•Elasticity on demand
– Anytime, anywhere
•Efficient scalability and high availability
•Suitable pricing models
– Pay for what you use

6. Cloud Computing
Evolution of Computing - The Next (Current) Big Thing
•Virtualization and Abstraction
– Details are abstracted from consumers
• Reduces complexity
•Not necessarily the Internet, can be on premises
– Private cloud
•Automation, Monitoring, Deployment
– Reduce cost, shift risk, shorten time-to-market, focus on business functionality

20. Roles
• Cloud Services are represented by roles
– Worker Role
• General Application that will run in the cloud
• Ideal for long running background processing
– Web Role
• Customized for web application programming as
supported by IIS 7 and ASP.NET.
• IIS setup is done for you.
