Windows AzureWindows Azure is an OS for the data center

Model: Treat the data center as a machineHandles resource management, provisioning, and monitoringManages application lifecycleAllows developers to concentrate on business logic

Provides shared pool of compute, disk and networkVirtualized storage, compute and networkIllusion of boundless resources

Provides common building blocks for distributed applications

Reliable queuing, simple structured storage, SQL storageApplication services like access control and connectivity

Modeling Cloud ApplicationsA cloud application is typically made up of different components

Front end: e.g. load-balanced stateless web serversMiddle worker tier: e.g. order processing, encodingBackend storage: e.g. SQL tables or filesMultiple instances of each for scalability and availability

How Java works on Windows Azure? A Java application works within a Windows Azure worker roleThe Java developer chooses and provides:

Java Runtime (JRE)Java App Server (Apache Tomcat, Jetty, Glassfish, etc)The app code/package

And then, when a new Windows Azure Worker Role starts: Startup task installs JRE, Web Server Package And bootstraps the Java Web Server with application

Microsoft’s building and funding community Eclipse Tools & SDKs to enable Java developers to easily take advantage of the Windows Azure cloud platform

Discussion TopicsDo you develop any Java based applications that you’d like to migrate to Windows Azure?  If so, please describe the type of application, frameworks and application server used.What timeframe are you looking to migrate?Are you planning on porting your application to leverage Azure PaaS capabilities?  If so, please describe the Azure components you’re planning on leveraging.Are you planning on keeping your application as-is (as much as possible) by leveraging the VM Role?  If so, please describe the components you’re planning on installing on the VM Role.
