What Is The Cloud?

• A set of connected servers
• On which developers can
• Install and run services
• Store and retrieve data

What Is Azure?
5

• Azure is a blue color on the HSV color wheel at
  210 degrees. Azure is the hue that is halfway
  between blue and cyan. Its complementary color is
  orange.
• Azure is a near synonym for the color blue.

Commonly it refers to a bright blue, resembling
the sky on a bright, clear day.

What Is Windows Azure?

• It is an operating system for the cloud
• It is designed for utility computing
• It has four primary features
• Service management
• Compute
• Storage
• Developer experience

9
Imagine Building A Desktop Application In This
Way

• Select your hardware, wire it all together
• Find some device drivers
• Write a file system
• Write a job scheduler
• Write an application installer
• This would be a complete waste of time!

10
But This Is What Every Cloud Service Developer
Has To Do Today!

11
What's The Answer On The Desktop?An operating
system

• An application execution environment that
  abstracts away the hardware
• A shared file system with access control
• Resource allocation from a shared pool
• Support for powerful programming environments
• Inter-operability with other systems

What Should The Cloud OS Provide?

• The same facilities that a desktop OS provides,
  but on a set of connected servers
• Abstract execution environment
• Shared file system
• Resource allocation
• Programming environments
• And more Utility computing
• 24/7 operation
• Pay for what you use
• Simpler, transparent administration

15
How Is The Cloud OS Manifested?

• Automated service management
• You define the rules and provide your code
• The platform follows the rules deploys,
  monitors, and manages your service
• A powerful service hosting environment
• All of the hardware servers load balancers
• Virtualized and direct execution
• Scalable, available cloud storage
• Blobs, tables, queues,
• A rich, familiar developer experience

16
Windows Azure

• Windows Azure is the foundation of Microsofts
  Cloud Platform
• It is an Operating System for the Cloud and
  provides Essential Services for the Cloud
• Virtualized Computation
• Scalable Storage
• Automatic Management
• Developer SDK

Our Approach to Azure Services
19
Web Role

• Web farm that handles request from the internet
• IIS7 hosted web core
• Hosts ASP.NET
• XML based configuration of IIS7
• Integrated managed pipeline
• Supports SSL
• Windows Azure code access security policy (CAS)
  for managed code

Public Internet
Web Role
Load Balancer
Storage Services
20
Worker Role

• No inbound network connections
• Can read requests from queue in storage
• Windows Azure specific CAS policy for managed
  code

Desktop And Related Azure Concepts

• Desktop

• Windows Azure

• EXE
• Application Configuration
• Manifest
• DLL
• Windows forms library
• Windows service
• Local data stores

• Service package
• Service configuration
• Service definition
• Service role
• Web role
• Worker role
• Internet data stores

25
Service Concepts

• Service definition
• Defines aspects of a service that cannot be
  changed without redeployment
• Types of roles and static role configuration
• Set of configuration settings for a role
• Contract with the environment code runs
• Service configurations
• Defines values for properties that can be
  dynamically updated for a running deployment
• Values of a configuration parameter
• Number of running instances

Windows Azure Storage Abstractions

• Blobs provide a simple interface for storing
  named files along with metadata for the file
• Tables provide structured storage. A table is
  a set of entities, which contain a set of
  properties
• Queues provide reliable storage and delivery of
  messages for an application

Simple Interface REST, ADO.NET Data Services
28
Interoperability

Azure Services Platform
29
Consistent, Familiar Development

• Visual Studio
• Templates
• Debugging
• .NET platform
• .NET, IIS7, WCF
• The cloud on your desktop
• Complete offline cloud simulation
• Like Cassini (web development server)

30
Not Just Websites

• Cloud services arent just websites
• Many other types of work for the cloud
• Bulk file conversion
• Heavy analytics
• Finding extraterrestrials
• Even websites can offload async work
• We need a more complex architecture

31
Publishing Your Service To The Cloud

• Write code on your laptop
• Upload your package to the web portal
• Push deploy
• Monitor, upgrade, scale

32
Debugging in the Cloud

• Debugging the cloud really means logging
• Simple logging API today
• More functionality over time
