4. Windows Azure is about Scale
• Windows Azure is
designed from the ground
up for true Internet scale
• Global presence
• Ride the “network effect”
• LinkedIn: 16 months for first
million users, 11 days for most
recent million
• Facebook: 5 years to hit 250m
users, 8 months to double
• Scale up and scale down
• Supports the “Scale Fast,
Fail Fast” model

5. Application Characteristics
“Scale & Elasticity”
• Need massive scale • target.com • walmart.com
• Social networking, web 2.0 • toysrus.com • barnesandnoble.com
• Need high reliability
• LOB, software as a service
• Have variable load / unpredictable ~4x normal load
lifetime (Holiday shopping)
• Ticketing, marketing
• Parallel processing
• Financial applications
• Don’t fit in well with a company’s
data center
• Avoid IT dept, joint ventures Jan 2009 Jan 2010
• Benefit from external storage

6. Helps your Systems Scale
• Most architecture is
hidden inside code
• Windows Azure
encourages you to
define your application
into constituent parts
• Windows Azure can
scale the parts of your
application as
appropriate

7. Flexible Architecture
• Systems evolve over
time
• Cloud is not an “all
or nothing”
proposition
• Windows Azure
makes it easier to
extend to the cloud

8. Opening up the Cloud
• Allow developers to
apply their existing
skills to the cloud
• Support for .NET,
Ruby, PHP, Java
• Interoperability with
any platform, tools or
technology

9. Natural Platform Evolution
• Windows Server 2008
• Virtualisation
• Windows Services,
such as IIS, logging,
diagnostics, etc
• Visual Studio & .NET
10. Flexible Business Model
• No up front
hardware
purchase
• Pay as you go
costing model
• Ideal in current
economical
climate

13. Managing Data Centric Applications with Capacity Bursts
Challenges Today
“Capacity Bursting“
Elastic scale – database as a service
Pay as you grow and shrink
Easy to provision and manage
Capacity
Average Time
Usage database
Compute
# of Hr’s
Average Usage No hardware, no manual database
administration required
Promotions, events, ticket selling
businesses are “bursts – bound” by
nature
Capacity constraints limit business agility
High costs of entry into new business
Difficult to roll out extra capacity quickly
Idle capacity “off-bursts” is cost
prohibitive

27. Windows Azure Roles
Your role class typically derives from
RoleEntryPoint represents role
Do initialization in OnStart()
Do work in Run()
You call into RoleEnvironment to enumerate
roles, endpoints, etc
You get called in response to changes in the
number of instances in the service
Can force restart
29. Windows Azure Blobs

modifying configuration settings, etc on
deployments
41. Windows Azure Diagnostics
Cloud is much harder than single server
Dynamic environment, no local access
Azure Diagnostics built for monitoring & data
collection
Focus on what to collect and when
Designed for Azure
Logging &
Based on standard APIs Diagnostics
Traces, logs, crash dumps, IIS logs,
perf counters, ETW, etc
Upload to Azure storage as required

42. Service Management CmdLets
PowerShell cmdlets wrapping Azure Service
Management and Diagnostics API
Simple to script out deployments, upgrades,
scaling
• Deploy new services
• Upgrade services
• Manage storage
accounts
• Transfer diagnostics
information
43. Service Upgrade Models
Rolling upgrade (aka “In-place”)
Roles are updated across update domains
one at a time
Service remains available during upgrade
Real-time hot swap (aka “VIP Swap”)
Virtual IP swap between staging &
production
Swap service endpoints of old/new
version
Enables complex architectural changes
Planned downtime
Stop and replace service with new version

Data or functionality that is “of value to many” –
enabling applications, reports, BI analysis, etc…
Examples include GIS/Spatial, traffic, movie show times,
crime, real-estate sales, financial data, navigation, census
data, reviews, etc…
Various Classifications:
Commercial: clean, supported, and regularly updated from
ISVs and Content Providers
Trusted Public Domain: clean, unsupported data from
academia and governments (Census, FDA, …)
Crowd Sourced: unreliable data in the public domain from
anyone and everyone

74.
75. Service Bus
Exposing internal applications on the
Internet isn’t easy
Network address translation (NAT) and
firewalls get in the way
The Service Bus:
Provides a cloud-based intermediary
between clients and internal applications
Provides a service registry that clients can
use to find the services they need
75
77. Access Control
Different organizations identify users
through many different techniques
Applications can be faced with a confusing
mess of security related code
The Access Control Service:
Implements a security token service (STS) in the
cloud
It accepts one token and issues another
An administrator can define rules for how this
claims transformation is done
