This document provides an overview of Windows Azure and its core concepts. It discusses: - Why cloud computing started and how Windows Azure came about to address challenges with managing machines. - Key characteristics of cloud computing like elasticity, reduced costs, and new capabilities. - Core Windows Azure services like Blob storage, Tables, Queues and AppFabric for identity management. - How to plan application architecture, deploy to Windows Azure using tools like Visual Studio, and manage applications once deployed.

1. A Lap Around Windows Azure Chris Ismael Developer Evangelist Developer and Platform Evangelism Microsoft Singapore

2. Goals and Agenda To get you to sign up for the Windows Azure Introductory Offer  http://bit.ly/freeazuresg Provide you with the “core concepts” knowledge that would be your foundation in understanding Windows Azure Agenda Why Cloud Computing? Why Would I… Define my website/service’s architecture Use Blob Storage, Tables, Queues Use Windows Azure AppFabric

3. Why Cloud Computing started How Windows Azure came about? Microsoft’s online services challenges Spending a lot of time managing the machines Inefficient utilization Little resource sharing No shared platform or standard toolset for everyone Reasons for major cloud providers Optimization (extra resources to share) ie Amazon Web Services Profit – economies of scale Strategic – product franchise Extension – customer relationships Presence – in market Platform – hub master of ISV’s offerings

4. Characteristics of Cloud Computing Value Proposition Elasticity No Commitment Reduced Cost Consumption-based Pricing Extra Capacity Faster Time to Market Self-Service IT SLA – 99.9% (over existing) Simplify IT Convert CapEx to OpEx New Capabilities – ie federated security Concerns Security Performance and Availability (ie storage) Vendor Lock-in Disaster Recovery In-house Capability and Process Billing Concerns Trust Alignment Best bet: Try it (bit.ly/freeazuresg) From David Pallman (davidpallman.blogspot.com)

5. Sample Scenario – Your typical Online Store The Service Model Signing up for Windows Azure Windows Azure Tool Set Portal and Service Management API Blobs and Tables Queues AppFabric Access Control Service (ACS) Planning / Architecture Purchasing (hardware, software licenses, etc) Prototyping / Testing Deployment / Management Adding new storage Decoupling components Managing identity (credentials)

7. Networking

8. Port configurations

10. Things to ponder on: This looks like Platform-As-A-Service (PAAS) Provides the tools and development environment to deploy applications Provides APIs to interact with the cloud components IAAS, SAAS Can I log-in to view these machines?

11. Signing up for Windows Azure

13. Things to ponder on Do I have to use Visual Studio to deploy? (show demo first) Is there a way to programmatically control and manage my deployments? Service Runtime API – let’s you access manipulate, and respond to the ambient environment in which your code runs (managed, native) Service Management API – meant to be run “outside” the cloud to manipulate your running services from outside (HTTP REST, free)

14. Sample Scenario – Your typical Online Store The Service Model Signing up for Windows Azure Windows Azure Tool Set Portal and Service Management API Blobs and Tables Queues AppFabric Access Control Service (ACS) Planning / Architecture Purchasing (hardware, software licenses, etc) Prototyping / Deployment Management Adding new storage Decoupling components Managing identity (credentials)

15. Storage using Blobs Blobs No need to predict how much storage is needed Persistent storage for your instances Scalable – consistent performance regardless of amount of data Replication of data REST HTTP / StorageClient libraries Why a new storage model? What’s wrong with the filesystem? When would I need a blob? What skills do I need to use blobs?

16. Blob Storage Concepts Blob Container Account IMG001.JPG pictures MOV1.AVI IMG002.JPG sally movies

17. Blob Demo

18. Things to ponder on.. Standard REST PUT/GET Interface http://<Account>.blob.core.windows.net/<Container>/<BlobName> StorageClient Library available Metadata can be associated per blob – 8K max Watch your wallet $0.15 per GB stored per month $0.01 per 10,000 storage transactions Windows Azure Drive… the C:solution (using VHDs)

19. Scenarios for using Queues

20. Queue Demo

21. Dequeue And Delete Messages Producers Consumers 1 C1 P2 4 1 2 3 1 3 2 C2 P1

22. Summary Of Windows Azure Queues Provide reliable message delivery Allows Messages to be retrieved and processed at least once No limit on number of messages stored in a Queue Message size is <=8KB

23. Tables First a little story about traffic signals… Versus traditional databases Denormalized data No schema – just name-value pairs No distributed transactions Black box – no settings Row size limits – 1MB Easy analogy = Excel sheet

24. Table Demo

26. Data resilience

27. CheapFastest to slowest query Unique partition key Partition key + row key Partition key No partition key/row

28. So do I need SQL Azure? Windows Azure Tables Denormalized data No schema – just name-value pairs No distributed transactions Black box – no settings Row size limits – 1MB SQL Azure Invert everything (pretty much) on the left, plus… Easier migration – MySQL/SQL Server -> SQL Azure, etc Has limits 10, 20, 30 – 50GB What if I need more than that???

29. Sample Scenario – Your typical Online Store The Service Model Signing up for Windows Azure Windows Azure Tool Set Portal and Service Management API Blobs and Tables Queues AppFabric Access Control Service (ACS) Planning / Architecture Purchasing (hardware, software licenses, etc) Prototyping / Deployment Management Adding new storage Decoupling components Managing identity (credentials)

30. Identity Management using AppFabric ACS Recap.. Scenarios You don’t want to manage passwords (how is that possible?) You don’t want to drastically change your existing code to handle logic for credentials You have an existing Identity Store (Active Directory) You want users to authenticate using several existing Identity Stores such as Live ID, Google, etc Claims-based identity to the rescue! (share analogy) – portal.appfabriclabs.com

31. Tokens aplenty!

32. Demo ACS
