.each instance runs on its own vm
....different vm sizes available
.replicated as needed
Comparison of Role Types
.Web Role : The role is hosted on IIS
.Worker Role : The role is an executable (you can create your
own web server, host a database, …)
.VM Role : The role is the VM
.Use Windows services, scheduled tasks, etc.
.You configure and maintain the OS.

(i.e. Less IT & Less Plumbing Code)
Service Models
.Windows Server 2008 R2 & IIS 7.5
.Web Role will use full IIS by default
.One Web role can run many Web sites
.Multiple sites, applications, virtual directories
.Everything else can be scripted (using admin access where necessary)
.Admin Access: Full administrative access to your
role instances
.Startup Tasks: scripts that automate the preparation and configuration of
roles
.Role Plugins: Ability to easily include “plug-ins” in the service definition (e.g.,
Built-in: Remote Desktop, virtual network, diagnostics)

VM Role – Overview
.Developers have full control over the OS image
.Ability to upload your own customized WS08R2
Enterprise images
.Operators can reboot, re-image and Remote
Desktop
.Continue to benefit from automated service
management, including service model
enhancements described on subsequent slides
Remote Desktop
.Portal-integrated Remote Desktop access to instances
within your deployment
.Use standard Remote Desktop client
.Support for all three role types – Web, worker, and
VMs
.Ability to take instances on/off the load balancer for
debugging

blob access
.Anonymous access for public downloadable and cacheable content
.Shared Access Signature (SAS) -> time limited, uniquely generated URLs
Sample
tables
.each entity can have up to 255 properties
.each property is stored as a <name, typed value> pair
.each entity requires a PartitionKey & RowKey
.transactions within partitions only
.no fixed schema
.continuation token for query results > 1000 entries

• Exchange messages between loosely coupled applications
• Network send/receive from any internet connected device
• Traverse NAT/Firewall
• Message buffering for loosely connected applications
• Pub-Sub scenario’s
• Facilitate direct peer-to-peer connection
• Based on WCF using industry standard protocols
• REST, SOAP, WS-* and TCP/IP
Azure AppFabric Caching
• Simple provisioning with zero configuration
• Quickly benefit from the out-of-the-box
ASP.NET providers
– Session state
– Page output caching
• Unleash the power …
– Use local cache for reference data
– Eliminate the need and cost of persisting transient
data in the data-tier

Windows Azure Connect
.Secure network connectivity between Windows Azure & on-premise
resources
.Quickly connect on-premise computers with the cloud, no networking
configuration required
.Supports standard IP protocols; secured using end-to-end IPSec
.Integrated with the Windows Azure Service Model; all role types
supported
Windows Azure Connect
Example use cases:
Enterprise Resources: Enable Windows Azure applications to
connect directly to on-premises resources without re-designing to
be Internet accessible (e.g., SQL Server)
Domain-Join: Join Windows Azure apps to on-premises Active
Directory; control access to Windows Azure roles based on
existing AD accounts and groups
Simplified Development: Directly connect from your
development machines to your Windows Azure instances, use
your favorite tools for configuring and debugging
Remote Administration: Use your existing tools for remote
administration tasks directly against your Windows Azure
instances (e.g., remote PowerShell)
