This document discusses cloud computing and Microsoft's Windows Azure platform. It defines cloud computing concepts like infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). It outlines the key components of Windows Azure including the Azure Fabric for running applications, Azure Storage for databases, and the Azure SDK. It also covers how to develop, deploy, and scale applications on the Azure platform using web and worker roles.

2. Agenda
• What is Cloud ?
• What is Windows Azure?
• Develop Your Application
• Deploy To Staging and Production
• Some Stuff To Think About

3. CLOUD !!!! (Puzzled)

4. Usage of Resources
• Software Resources
• Computing Resources
• Platform Resources

5. Cloud Computing means
• IaaS - Infrastucture as a Service
• PaaS – Platform as a Service
• SaaS – Software as a Service

6. Infrastructure as a Service
Major Infrastructure Vendors - Below are companies that provide
infrastructure services:
• Microsoft : WINDOWS AZURE
• Google (GOOG) - Managed hosting, development environment
• International Business Machines (IBM) - Managed hosting
• SAVVIS (SVVS) - Managed hosting
• Terremark Worldwide (TMRK) - Managed hosting
• Amazon.com (AMZN) - Cloud storage

7. Active Platforms
 Windows Azure Platform
 Google (GOOG) - Apps Engine
 Amazon.com (AMZN) - EC2
 Microsoft (MSFT) - Windows Live
 Terremark Worldwide (TMRK) - The Enterprise Cloud
 Salesforce.com (CRM) - Force.com
 NetSuite (N) - Suiteflex
 Mosso - Mosso, a division of Rackspace
 Metrisoft - Metrisoft SaaS Platform

8. Traditional v/s On-Demand
Traditional On-Demand
SAP AG (SAP)

 Device and Location Independence
 Multi-tenancy
 Centralization
 Peak-load capacity
 Utilization and efficiency
 Reliability
 Scalability
 Security
 Sustainability

10. Ok. So what’s Windows Azure?
• Microsoft’s “cloud”
• Custom version of Windows
– Optimized for utility computing applications
– Always runs virtualized on the Azure Fabric
• Azure Fabric
– Runs instances of your apps
– Handles “everything”
• Azure Storage
• Azure SDK for Visual Studio

11. The Azure Platform

12. The Azure Platform

13. The “cloud” in Cloud Services?
• Think data-center somewhere on the
internet
• Allows you to run your app
• Allows you to read and write data

14. Why Azure?
• “I’ve got my awesome data-center so…”
• No more worrying about…
– Buying, configuring, maintaining hardware
– Buying, configuring, maintaining the operating system
– Network infrastructure
• Routers, Switches, Load Balancers
– Your data-center’s power and internet connections
– Failovers
• Worry less about…
– App deployment
– Capacity planning
• Focus on writing your app

15. Simple Scale Out
• Changes in traffic
• Need more servers?
• Need fewer servers?

16. I want everything…
• …and it should be easy.
• Azure let’s you worry about writing your
app
• Don’t have to learn a whole bunch of new
stuff
• Leverage your existing dev skills

17. Azure: The Developer View
• Write it in Visual Studio
– New project types
– Debug your code
• .NET, ASP.NET, WCF, IIS7, LINQ
• Azure Storage
– Database in the cloud
– (with a few caveats)
• Desktop development versions of
– Azure Fabric
– Azure Storage

18. AZURE STORAGE

19. Azure Storage
• Simple database in the cloud
– Tables
• “structured storage”
– Blobs
– Queues
• You don’t worry about replication
• Scales like nobody’s business
• Development version
– DevelopmentStorage.exe
– Uses SQL Server Express

20. Table Storage
• Every row has RowKey & Partition Key
• RowKey = primary key
• PartitionKey
– Helps you tell Azure how to scale your data
– You have to think about how you’ll be querying
– By State? By Hour? Other?
RowKey PartitionKey FirstName LastName
1 MA Ben Day
2 MA John Malkovich
3 WA Bill Gates
4 CA Steve Jobs

21. Column Data Types
• Partition key and Row key
– String (up to 64KB)
• Other properties
– String (up to 64KB)
– Binary (up to 64KB)
– Bool
– DateTime
– GUID
– Int
– Int64
– Double

22. MORE THAN JUST ASPX

23. Utility Compute without a UI
• Azure uses the concept of “Roles”
• There are two types of roles:
– Web role
– Worker role

24. Web & Worker

25. Worker Role and a Queue
• In a web role, create an ASP.NET page
– Creates a queue
– Writes to a queue
– Gets queue depth
• Worker Role
– Reads the queue
– “Processes” the message

26. DEPLOYMENT

27. Deploy To The Cloud
• Change the storage config to use
production servers
• Deploy your App to the staging platform
• Test your app at the staging
• Publish your app to the production engine

28. The Big Questions
• When?
– 2009
• An actual Service Level Agreement (SLA)
• More data-centers
– Now in US only
– Global at go-live
• What will it cost?
– It will depend on what you use
