Windows Azure

Definition of cloud (NIST)
On-demand self service
Standardized access
Location independant resource pooling
Rapid elasticity
Pay per use

The Windows Azure Platform
Windows Azure
SQL Azure
Windows Azure platform AppFabric
Microsoft Codename “Dallas”
Microsoft Codename “Sydney”

Windows Azure
Flexible application hosting
Lights-out service management
Provide code & service model, hit ENTER
Storage at massive scale
Blobs, tables, queues
Compute
Storage
Management

Windows Azure

Storage options
Blobs, tables, queues
Windows Azure Drive (a.k.a. XDrive)
Virtual NTFS volume that can be mounted
.vhd format
Use existing NTFS API’s
Easier migration
Stored on blob storage provides quick mount/unmount in other VM

SQL Azure
Relational database as a service
Highly available, automatically maintained
Extension of the SQL Server Data Platform
Reporting
Data Sync
Business Analytics
Database

SQL Azure
Relational database, provided as a service
Highly symmetrical development and tooling experience (use TDS protocol and T-SQL)
Highly scaled out, on commodity hardware
Built on the SQL Server technology foundation
High availability, DB provisioning, and DB management are provided by the service

Windows Azure AppFabric
Secure connections between services
Across organizational boundaries
Claims-based access control
ServiceBus
AccessControl

Service Bus Overview

Windows Azure AppFabric - Service Bus
Securely connect applications
Over the internet
Across any network topology (= across firewalls!)
Across organizational boundaries
Primary application patterns
Eventing:
Notify applications and/or devices
Service Remoting:
Securely project on-premises services out to the cloud
Tunneling:
App-to-app communication with NAT/Firewall traversal

Microsoft Codename “Dallas”
Content brokerage and discovery platform
Available as a CTP
Microsoft Codename “Dallas”Information Services

Microsoft Codename “Sydney” - Connectivity
WINDOWS AZURE PLATFORM
ENTERPRISE
Data Service
Service Bus
Access Control Service
Code Name “Project Sydney”

An existing application

Time Tracker
Originated from the ASP.NET starter kithttp://www.asp.net/downloads/starter-kits/time-tracker
Small modifications:
List of projects from internal billing system
Time registration can have an attachment

TimeTracker – On-premise

Time Tracker
There are some problems with it...
Running on 2 web servers that are > 2 years old, nearing EOL
Looking to buy new hardware
Looking to deploy the application in a cloud
Spikes near the end of each month, reducing performance
Looking to buy additional hardware
Looking to deploy the application in the cloud
They do have this “seamless scaling” thing, right?

Workload Patterns Optimal for Cloud
“Growing Fast“
“On and Off “
Inactivity
Period
Compute
Compute
Average Usage
Usage
Average
Time
Time
On & off workloads (e.g. batch job)
Over provisioned capacity is wasted
Time to market can be cumbersome
Successful services needs to grow/scale
Keeping up w/ growth is big IT challenge
Complex lead time for deployment
“Unpredictable Bursting“
“Predictable Bursting“
Compute

Average Usage

Time
Unexpected/unplanned peak in demand
Sudden spike impacts performance
Can’t over provision for extreme cases
Services with micro seasonality trends
Peaks due to periodic increased demand
IT complexity and wasted capacity

Challenges
Security?
Forms based
Claims based (AppFabric access control service)
Availability & scalability out-of-the-box
Still keep session state in mind
Specify “upgrade domains”
Logging & tracing
System.Diagnostics.Trace
Performance counters
All stored on blob storage, not real-time!
Operating system
Windows Azure Cloud OS 1.0 – 1.1 – x.x
See MSDN for patches and hotfixes in each OS version
New cost model
Pay-per-use
Allow for scale-up and scale-down

Moving an application to the cloud
refactoring

TimeTracker on steroids!
Our company decided to go for Windows Azure
New migration track started
Learn about Windows Azure
Support deployment on Windows Azure
Store data in SQL Azure
Store attachments on blob storage
Somehow connect with the billing system to get a list of project names
Deploy

Convert the TimeTracker solution to a Cloud Service solution
Make sure it can be packaged for deployment
Make sure it runs on Development Fabric
Requirements:
IIS7
Visual Studio
Windows Azure Tools for Microsoft Visual Studio
Windows Azure SDK (shipped with the above)

Windows Azure Tools for Microsoft Visual Studio
Get them on www.azure.com

Converting the TimeTracker solution

Deploy

There is a database on-premise in SQL Server
Schema should be migrated
Data should be migrated
Requirements:
Native SQL client
SQL Management Studio

Migrating schema and data
SQL Azure Migration Wizardhttp://sqlazuremw.codeplex.com
SQL Azure Data Sync Tool for SQL Serverhttp://www.microsoft.com/windowsazure/developers/sqlazure/datasync/
SQL Server Management Studio 2008 R2 November Community Technology Preview

Migrating data to SQL AzureSynchronizing SQL and SQL Azure

ASP.NET Membership & Roles
Will not work out of the box!
Some incompatible SQL
Updated scripts and aspnet_regqslazure.exe
http://support.microsoft.com/default.aspx/kb/2006191

Deploy

Attachments currently stored on the web server
Windows Azure server storage not guaranteed to survive
There’s an option for that...
...but it will still fail in some situations
Ideal candidate: blob storage
Requirements:
Windows Azure SDK
A tool to browse storage and see if it works

Tools to see if it works
CloudBerryLab Explorerhttp://www.cloudberrylab.com
Azure Storage Explorerhttp://azurestorageexplorer.codeplex.com/
Onlinehttp://myazurestorage.com
Visual Studio 2010 tools

Storing attachments on Windows Azure blob storage

Deploy

Connect with the billing system
List of projects comes from on-premise billing system
TimeTracker will be in the cloud
Requirements:
Expose the billing system to the Internet
Connect to it

Service Bus Overview

Connect with the billing system
List of projects comes from on-premise billing system
TimeTracker will be in the cloud
Communication will happen over the AppFabric service bus
Requirements:
Visual Studio
AppFabric SDK

Using AppFabric service bus

Another option…
Billing system WCF configuration was changed
If that’s not possible: PortBridge to the rescue!http://bit.ly/bCDrUs

Deploy

Deploy
Package up the application
Deploy the thing
Requirements:
Windows Azure SDK
A web browser

Deploy

What to remember?
Windows Azure is
Operating system (computing & storage)
SQL Azure
AppFabric
Your application and skills
Hybrid applications are possible
It’s not that hard to do
