the hybrid windows azure application
DESCRIPTION
The Windows Azure platform is a fairly feature rich environment. You can run your web applications there. You can run your data processing applications (services) there. But you don’t have to run your entire application there. You can run part of your application in “the cloud”, and part of your application on premise – giving you the best of both worlds. But why would you not put everything in the cloud? Perhaps you don’t need the massive computing power Windows Azure provides, but you would like a cheap an easily accessible data store. Maybe your application just isn’t ready, yet, to be run in the cloud. Whatever the reason, in this session you will learn the basics for creating a hybrid application which leverages various features of Windows Azure. You will see how to leverage Windows Azure’s rich features and APIs to extend your application to new heights.TRANSCRIPT

HYBRID APPLICATIONS
Application Trends
1970s• Mainframe
• COBOL
1980s• Client-Server
• COM+, Two tier architectures, C/C++
1990s• Web
• ASP, PHP, Tight Coupling, Web Servers
2000s• SOA
• .NET & Java, N-Tier Architectures, ESB, Data Warehousing
2010+• Hybrid /

Hybrid Clouds – The New Reality?
• Destined to be the most common “type” of cloud.
• Determine what to keep private vs. what is OK for public exposure.
• Architectures become complex.
• Balance of cost, control, flexibility, and risk.
* Cloud Computing Use Cases White Paper 2009
Composite Systems
“By 2015, 80% of transformational systems implemented by midsize and large enterprise will be compositions.”
- Gartner
Why Consider a Hybrid Approach?
• Expose key functional areas as services enable agility
• Improvements in on-premises and cloud
• Shift from single product, big iron approach -> best in class, capability driven model
• SOA – service composition of on-premises and in the cloud.
• Reduce the big spend.

Additional Scenarios
Big Data• Embrace Apache Hadoop on Windows Server and Windows
Azure (see https://www.hadooponazure.com/)
HPC• Financial risk, engineering, weather modeling, etc.• Windows Azure HPC Scheduler• http://www.windowsazure.com/en-us/home/scenarios/parallel/
Cloud Bursting (extending data center to cover peak load)• Kelly Blue Book uses Windows Azure as a secondary data
center to handle bursts in traffic and new features. Saved $100,000/year.
Windows Azure Service Bus
• Robust messaging and routing services
• Hybrid apps that span on-premises and the cloud
• Specifically designed to traverse NAT and firewall devices.
• Security via ACS

Message Relay
Service Bus Message Queues(Brokered Messaging)
• Reliable and durable – backed by SQL Database• Store up to 1GB per queue• No maximum TTL – unlike Windows Azure queues• 256KB maximum message size• Messaging API, WCF, and REST interfaces
Publisher ReceiverQueueReceiver
ReceiverReceiver
Service Bus Topics (pub/sub)(Brokered Messaging)
• Takes SB Queues to the next level• 2,000 subscriptions on a single Topic• Subscription is a virtual queue – gets a copy of each message• Filters
– SQL92 syntax to receive only messages with matching properties
• Actions– Modify message properties as they’re selected

ADDITIONAL CONNECTIVITY OPTIONS
A Few
Access Control Services (ACS)
• No need to build your own identity management solution.• Authenticate (WIF – OAuth and WS-Federation)• Claims-based authorization• Multiple Identity Providers (ADFSv2, Google, Live ID,
etc.)• Ability to bring your own via membership• Write to ACS and let Microsoft worry about the rest
Windows Azure Virtual Machines
• Persistent VM• Full control and management of virtual machines• Windows or Linux• Support for Active Directory, SharePoint, BizTalk & SQL
