Why the Cloud?
“The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.”
“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets”

.NET API differences
Permanent storage
Do not store data to local disk (ie C:), but you can use it as a Scratch disk
Use the Azure API’s for working with Azure Storage (Blobs/Queues/Tables) or use SQL Azure
You can mount a VHD inside a Blob and mount it as an NTFS drive using Azure Drive to quickly move your application to Azure without rewriting your storage logic.

Logging & Diagnostics
Log using Microsoft.WindowsAzure.Diagnostics
Third party libraries
Enterprise Library 5.0 supports Azure
NLog(http://nlog-project.org/)
Ethos has written a plug-in for NLog to send log to Azure log
Log4Net
Several implementations of AzureAppender on the net
Diagnostics: Read logs using
MMC plugin
System Center
PowerShell cmdlets
DoItYourSelf using Azure API
Cerebrata AzureDiagnosticsManager
Remote Desktop 

Existing software assets
Legacy system integration using AppFabric and connectors
Coming soon: «Windows Azure Connect»
With Windows Azure Connect, you can configure IPsec protected connections between computers or virtual machines (VMs) in your organization’s network, and roles running in Windows Azure
Microsoft Sync Framework
VM Role

Sending mail from Azure
Mail service is not integrated in Azure
Implement a SMPT sender queue
Connect to a SMPT server to send mail using System.Net.Mail.SmtpClient
Connect to a POP3 server to receive mail. Find a working code sample at CodePlex
If you send a lot of mail do not use a free provider, use a commercial provider like SendGrid

What is SQL Azure
Similar to an ordinary SQL Server, exposes a tabular data stream (TDS)
Familiar SQL Server relational model
Uses existing API and tools (SQL2008R2)
Friction free provisioning and reduced management
At the moment, max database size is 50GB
Coming : SQL Azure Federation Support (spring 2010 )

SQL Azure Under The Hood
Applications use standard SQL client libraries: ODBC, ADO.Net, …
Application
TDS (tcp:1433)

Features and Types
SQL Azure does not support all of the features and data types found in SQL Server
Analysis Services, Replication, Reporting Services, and Service Broker are not currently provided as services on the SQL Azure.
Reporting Services was announced 28. October at the PDC, soon available as a CTP

Transacts SQL support
Transact-SQL Features Supported
Constants
Constraints
Cursors
Index management and rebuilding indexes
Local temporary tables
Reserved keywords
Stored procedures
Statistics management
Transactions
Triggers
Tables, joins, and table variables
Transact-SQL language elements such as
Create/drop databases
Create/alter/drop tables
Create/alter/drop users and logins
and so on.
User-defined functions
Views, including sys.synonyms view
Transact-SQL Features Unsupported
Common Language Runtime (CLR)
Database file placement
Database mirroring
Distributed queries
Distributed transactions
Filegroup management
Global temporary tables
Spatial data and indexes
SQL Server configuration options
SQL Server Service Broker
System tables
Trace Flags

SQL Azure Migration Wizard
Upgrade your database to SQL2008 first
Download the Wizard sqlazuremw.codeplex.com
Run the Migration Wizard
Analyse and fix the reported issues before migrating
You can also script directly from inside SQL Management Studio to SQL Azure
Transfer data using BCP – generate CMD script in SQL

Top identified problems
All tables need a clustered index
UNIQUEIDENTIFIER, NEWSEQUENTIALID, DATETIME,
ROW GUID COLUMN not supported
Used for Merge replication, use Sync Framework instead.
SELECT INTO is not supported
Both on physical tables and temp tables
Global temp variables not supported
##GlobalTmpTable
SQL Server Agent not included
There is no Backup functionality
Sync or stream to disk

How to optimize for Azure
SQL Azure Database Pricing (if app is not CPU bound)
$9.99/month for 1 GB
increases linearly to $499.95/month for 50 GB
This is the main cost driver for hosted solutions on Azure
Azure Storage Pricing (Blobs/Queues/Tables)
$0.15/GB stored/month
Suggested actions:
Aggregate transactional data that you need to report later
Move data to Azure Table Storage or export to Azure Blobs
The Table service is designed for massive scalability and availability, supporting billions of entities and terabytes of data. It’s designed to support high volume, but smaller structured objects.

Reflections on Security
Protecting yourself

Securing the Network, Host and Application – On-premise

Securing the Network, Host and Application – In the Cloud

Threat Modeling Web Applications
Step 1: Identify security objectives. Clear objectives help you to focus the threat modeling activity and determine how much effort to spend on subsequent steps.
Step 2: Create an application overview. Itemizing your application's important characteristics and actors helps you to identify relevant threats during step 4.
Step 3: Decompose your application. A detailed understanding of the mechanics of your application makes it easier for you to uncover more relevant and more detailed threats.
Step 4: Identify threats. Use details from steps 2 and 3 to identify threats relevant to your application scenario and context.
Step 5: Identify vulnerabilities. Review the layers of your application to identify weaknesses related to your threats. Use vulnerability categories to help you focus on those areas where mistakes are most often made.

Windows Azure Security Notes
Tackling cloud security can be overwhelming without an approach.
These notes summarize how we took a look at securing Web applications, web services, and data in the cloud.
We basically started by mapping out common application scenarios.
We then figured out a way to group threats and attacks into a set of common categories.
These categories make it easy for us to analyze and inspect the various parts of an application and engineering decisions.
Then we focused on finding common principles, patterns, and practices, while working with customers, field, product teams, and industry experts.

Observed Performance

Cloud Benefits - Real-world Performance Analysis
For very limited service requests, Azure-based solution takes slightly longer time to response than self-hosted solution.
When more service requests come in, response time of self-hosted solution’s longest transaction will be longer. Meanwhile, response time of Azure-based solution’s longest transaction looks comparatively steady.
When service requests increase rapidly, transaction rates of self-hosted solution drops down very fast, meanwhile transaction rates of Azure-based solution looks comparatively better.

Performance Benchmark
Hardware configuration: Legacy: CPU: 2.4G+2.4G; Memory: 1GB; Hard Drive: 60GB
Azure Small Instance: CPU: 1.6GHz; Memory:1.75G; Hard Drive:225G

Understand difference and workaround of APIs
Build scalable, multi-tenant application for Azure
Maximize existing software assets’ value
Build secure solutions for Azure
Build cost-effective solutions for Azure.

Other Tips

Make your data available as OData
Open Data Protocol (OData) builds on top of WCF
Makes it easy to consume your data from different consumers
Browsers
Applications (OData Explorer, PowePivot for Excel, LinqPad, .NET, SilverLight)
Java, JavaScript, PHP
iPhone
Windows Phone 7
