SESSION 2 The Azure Platform

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. http://en.wikipedia.org/wiki/Azure

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

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

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

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 do Not relational No Referential Integrity No Joins Limited Queries No Group by No Aggregations No Transactions What tables can do Cheap Very Scalable Flexible Durable If 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

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

Live Mesh

Quick Walkthrough and Demo (not nearly as impressive as the video)

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
