Azure Services

• Azure Blob => AWS S3

• Azure SQL Database => AWS RDS

• Azure Tables => AWS Dynamo DB

• Azure Queues => AWS Message Queue Service

Create a web service in VS 2013We know the drill…

Modify web.config too

C# LINQ

• One of my favorite features in C#• Create [WebMethod] – public List<int> ShowResults(int N)– Create N integers {0…N-1}• Square them• Order by Descending!• Convert them to String

– Using LINQ• << demo >>

Azure Tables

• Like Amazon’s DynamoDB

• “Infinite” scaling

• Map in the cloud (key/value pair)

Azure Tables

[WebMethod]• Read PA1 CSV data file into memory

[WebMethod]• Save PA1 data to Azure Tables

[WebMethod]• Search Azure Tables for data

Azure Tables

• Create NBAPlayerStats Class

• Read PA1 CSV data file via LINQ

Azure Tables

• Insert & Read Player data Warning:Insert & Read should be different web methods.

This is just code blocks.Search on Goog for “azure table tutorial”

Part 2 = search via points per game

Azure Queue

• Like Amazon’s Message Queue

• Communicate between machines

• Property = any machine reading the queue can take the data

• FIFO

Azure Queue

[WebMethod]• Insert url into Queue

[WebMethod]• Read url from Queue (invisible for limited

time)

Azure Queue

Warning:You need to write the web methods. This is just code blocks.

Why do we need delete message?
