Azure
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.

Blobs Queues
HTTP
Tables
Storage types: Blobs: a simple hierarchy of binary data Tables: hierarchical storage (not relational
tables) Queues: allow message-based communication
Access: Data is exposed via a RESTful interface Data can be accessed by:
▪ Windows Azure apps ▪ Other on-premises or cloud apps
Table . . .. . .Table Table
Entity . . .. . .Entity Entity
Property PropertyProperty
Name Type Value
Storage Accounts
Access via REST You can’t use ordinary ADO.NET
No SQL Query language based on the LINQ C# syntax No real joins, aggregates, etc.
An unfamiliar hierarchical structure You can’t easily move relational data to it Supporting services are scarce, e.g., reporting There’s significant platform lock-in
No schema And no views
Massive scalability By effectively allowing scale-out data
Highly durable Perspective:
Applied to the right problem, Windows Azure Tables are a beautiful thing▪ But they’re not the optimal solution for a majority of
data storage scenarios Amazon, Google, and others do quite similar
things▪ It appears to be the state of the art for scale-out data
What tables don’t doWhat tables don’t do

CheapCheap
Very ScalableVery Scalable
FlexibleFlexible
DurableDurableIf these are important to you, use:
Data stored in Tables A Table is a set of Entities (rows) An Entity is a set of Properties (columns)
Entity has: PartitionKey – enables scalability RowKey – unique id within the partition
(the only indexed property) Timestamp – for optimistic concurrency 255 properties for your data Max size of 1MB
Queue
Web Role
ASP.NET, WCF,
etc.
Worker Role
main(){ … }
1) Receive work
2) Put work in queue
3) Get work from queue
4) Do work
To scale, add more of either

Queues guarantee a message will be processed at least once
Allows recovery in the event of errors Roles normally consist of several tasks
1. Get Message2. Insert to Table13. Insert to Table2
Could fail at any point Write your code to expect failures
Inserts/Deletes might fail as already performed
Data in inconsistent state (part processed)
Same tools you’re already used to using, namely Visual Studio
Real Storage & Dev Store have differences Fixed schema No dynamic table creating
String length nvarchar[1000] – String[64000] Dev Storage forces you to use certain patterns Can be difficult to debug issues in data store:
Use logging and tracing Use Fiddler, SQL profiler and SDK docs
Your Applications
Key developer challenges Many identity providers, many vendors, many
protocols, complex semantics – tricky to get right Application strewn with one-off access logic Hard to get right, not agile, not compliant, many
dead ends Approach
Automate federation for a wide-range of identity providers and technologies
Factor the access control logic from the application into manageable collection of rules
Easy-to-use framework that ensures correct token processing
Key developer challenges Want to easily describe long-running processes Want modularity and nesting Easy to describe but in practice harder to run
▪ Hosting and scaling can be challenging▪ Setup and installing, define scale-out
approach, ensure long-running availability, manage upgrades, …
Approach .NET 3.0/3.5/4.0 addresses key developer
requests .NET Services makes it easy to deploy, manage
and run Workflows
The problem: Exposing internal applications on the Internet isn’t easy Network address translation (NAT) and
firewalls get in the way The solution:
Service Bus provides a cloud-based intermediary between clients and internal applications
It also provides a service registry that clients can use to find the services they need

Chose Microsoft® Virtual Earth™ with the Microsoft MapPoint® Web service
Integrated location information to provide location hours and services
Added 3-D maps and integrated driving directions
FedEx wanted to increase its visibility and improve customer experience
Wanted to add location information and rich features to its online store locater
Stable, well-supported solution platform was a must
FedEx improves customer experience with integrated mapping and location data
“With Virtual Earth, rather than clicking 10 times to find information, customers get it right away with the
compass control.”SNarayanan Kasiarunachalam, Technical Advisor, FedEx

External Commentary
#1 Coolest technology demoed at Web 2.0
“Live Mesh… could change the way PCs and other devices interact with Internet Services and each other…”
“… most ambitious step yet in transforming its personal computer business
“Despite Microsoft’s reputation of being a closed-wall company, it is adopting simple protocols in its Live Mesh synchronization strategy.”
“Live Mesh represents the company Microsoft is trying to become…” Rob Enderle
“Eventually, we’ll give customers instant access to any movie on any device with an Internet connection and a screen.” “More immediately, we could use this technology to reach into airports. Travelers could quickly download movies from Blockbuster kiosks to their portable media players.”
Keith Morrow Chief Information Officer, Blockbuster
