What is “the cloud”
− “cloud computing” is using software or infrastructure services hosted over the Internet - Hilton Giesenow

Windows Azure, On One Slide
− The “cloud” is− 1000s of geo-distributed servers & networking
− Windows Azure − An operating system for the cloud
− The “operating system” provides− Application hosting− Automated service management
− Upload your code and “service model”; press START
− Durable storage at massive scale
![Page 6: Hilton Giesenow Principal Consultant, 3fifteen Microsoft MVP](https://reader035.vdocuments.site/reader035/viewer/2022062408/56649de95503460f94ae3d5e/html5/thumbnails/6.jpg)
Why the Cloud
− VERY Quick Provisioning− New business− Growing business (up OR down)
− Easier Maintenance− Lower TCO
− “commodity” / “utility” computing− Schedules of usage− Spikes in usage
− Unpredicted− Predicted

SQL Azure Database Overview
− Relational database, provided as a service− Highly symmetrical development and
tooling experience (use TDS protocol and T-SQL)
− Highly scaled out, on commodity hardware
− Built on the SQL Server technology foundation
− Beyond “hosted database”− High availability, DB provisioning, and DB
management are provided by the service− Pay for what you use

Overview
− High Availability− Quick Provisioning− Low Cost− _Subset_ of SQL Server 2008− Shared – play nice!
− Throttling− 5 mins idle time− 5 mins long-running operation

SQL Azure Service Provisioning
> Each account has zero or more servers> Azure wide, provisioned in a common portal
> Billing instrument
> Each server has one or more databases> Contains metadata about the databases
> Unit of authentication and security
> Unit of Geo-location
> The server is a logical grouping of your DBs
> Each database has standard SQL objects> Unit of consistency
> Contains users, tables, views, indices, etc…

Synchronization− Why you need sync:
− Incremental changes− Unreliable and/or slow network− Conflict detection and resolution− Topology flexibility
− How to get sync:− Build it yourself, but sync is not easy!− Use Microsoft Sync Framework

Fundamental Storage Concepts− 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
− Blobs – Provide a simple interface for storing named files along with metadata for the file
− Drives – Provides durable NTFS volumes for Windows Azure applications to use (new)

Queue Summary
− Pattern− Read -> Process -> Delete
− Must Delete!− Otherwise it re-emerges− New: Dequeue Count
− No guarantee of “delivery” – final processing− Idempotency− No ordering

Blob Features and Functions− Store Large Objects (100s of GBs in size)
− Associate Metadata with Blob− Metadata is <name, value> pairs, Up to 8KB
per blob− Set/Get with or separate from blob data bits
− Standard REST Interface− PutBlob, GetBlob, DeleteBlob− CopyBlob, SnapshotBlob, LeaseBlob
− CDN (with Edge services)

Windows Azure Tables− Provides Structured Storage
− Massively Scalable Tables− Billions of entities (rows) and TBs of data− Can use thousands of servers as traffic
grows
− Highly Available & Durable− Data replicated several times
− Familiar and Easy to use API− ADO.NET Data Services – .NET 3.5 SP1
− .NET classes and LINQ− REST

Access Control Services
− Claims-based access control− Key capabilities / features:
− Integrates with AD FS v2, but also…− Usable from any platform (for real)− Implements OAuth WRAP & SWT− Enables simple delegation
A web service can take advantage of these capabilities with ONE
code base
