Windows Azure, On One Slide

The “cloud” is

1000s of geo-distributed servers & networking

Windows Azure is analogous to

An operating system for the cloud

The “operating system by analogy” provides

Application hosting

Automated service management

Upload your code and “service model”; press START

Durable storage at massive scale

Azure Service Architectures

A service consists of

An isolation boundary

A set of component roles each with endpoints

Numbered, identical instances of each role

Azure Service Architectures A role instance is a set of:

Configuration

local data

deployed in a dedicated VM

Web Role: The role is hosted on IIS

Worker Role: The role is an executable create your own web server

host a database

host Java VM, Ruby etc.)

Worker

Azure Service Architectures

A service is reachable externally via a single VIP for load-balanced traffic to multiple endpoints

Endpoints are reachable internally over TCP, HTTP Runtime API exposes & updates IP/Port values

Demo: “Hello Cloud” with Visual Studio 2008/ 2010

Sample: Notification Of New Instances

Sample: Inter-role communication

2 VM Roles (currently) available: Web role

External synchronous HTTP/S communication

Worker role External HTTP/S / TCP communication

Mental model: “it‟s like a Windows Service”

Windows Azure Operating System Automatic /manual upgrades

Storage Local storage is volatile (!)

Tables Provide structured storage. A Table is a set of entities, which contain a set of properties

Queries

Entity Group Transactions

Avoid “Append only” write patterns based on PartitionKey values

Avoid using monotonically increasing suffix with a constant prefix

Example: using only the current timestamp as PartitionKey

If needed, add varying prefix to PartitionKey

Restructure your schema if required

Concatenate different keys to form appropriate index

Most Optimal: PartitionKey == “SciFi” and RowKey == “Star Wars”

Scans: Expect continuation tokens PartitionKey == “SciFi” and “Sphere” ≤ RowKey ≤ “Star Wars”

“Action” ≤ PartitionKey ≤ “Thriller”

PartitionKey == “Action” || PartitionKey == “Thriller” - currently scans entire table

“Cars” ≤ RowKey ≤ “Star Wars” - scans entire table

SQL Azure Tips

Developing on a local SQL Express instance has some advantages

Easy to get started, you already know how to do it!

Full fidelity with the designer and debugging tools

Reduces latency when using local Azure development tools

Reduces bandwidth and databases costs for development

Some caveats

Remember to alter your VS build settings to switch the connection string when deploying

Use tools (like SQLAzureMW) to keep you within the supported SQL Azure features

Always test in SQL Azure before deploying to production

SQL Azure Migration Wizard

http://sqlazuremw.codeplex.com

SQL Azure Tips SQL Azure connection strings follow normal SQL syntax

Applications connect directly to a database “Initial Catalog = <db>” in connection string

No support for context switching (no USE <db>)

Some commands must be in their own batch Create/Alter/Drop Database & Create/Alter/Drop Login, & Create/Alter USER with FOR/FROM LOGIN

Encryption security Set Encrypt = True, only SSL connections are supported

TrustServerCertificate = False, avoid Man-In-The-Middle-Attack!

Format of username for authentication: ADO.Net: Data Source=server.database.windows.net; User ID=user@server;Password=password;...

Setup your firewall rules first!

SQL Azure Tips

SQL Connections: Retry on failure

Connections can drop for variety of reasons Idleness

Transient (network) errors

Intentional throttling

First step: reconnect immediately Handles idleness- and transient-disconnects

Gateway handles connection retry for app Connections attempted for ~30s before failure

What to do on connection failure? Wait (10 seconds), then retry

Change your workload if throttled

SQL Connection Retry Pattern

while (true)

using (SqlConnection connection = new SqlConnection(connStr))

connection.Open();

using (SqlCommand cmd = connection.CreateCommand())

cmd.CommandText = @"SetBCPJobStartTime";

cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add(new SqlParameter(@"@BCPJobId", BCPJobId));

cmd.ExecuteNonQuery();

catch (Exception exc)

// deal with error

// more stuff

SQL Azure Labs Data Sync

Service Remoting

Control Web services through the Internet using Service Bus

Sender solicits information from listeners

Service Bus

Access Control

Eventing

Notify remote parties of events

Sender transmits information to listeners

Listeners may handle events in different ways

Tunneling

Traverse network borders without opening firewalls
