- 3. Device developers need to think about …. scale
- 8. Only a scalable elastic computing infrastructure can solve this scalability challenge; such as Windows Azure

- Slide Objectives:Explain how Microsoft thinks of the cloudSpeaking Points:There are numerous terms and definitions floating around in the industry for “the cloud”, “cloud computing”, “cloud services”, etc.Microsoft thinks of the cloud as simply an approach to computing that enables applications to be delivered at scale for a variety of workloads and client devices.The cloud can help deliver IT as a standardized service…freeing you up to focus on your business
- Slide Objectives:Explain the three established industryterms for cloud servicesSpeaker Notes:There is a lot of talk in the industry about different terms like Platform as a Service, Infrastructure as a Service, and Software as a Service.Since PDC08 when we first announced the Windows Azure our focus has been on delivering a platform as a service offering where you can build applications. Where the platform abstracts you from the complexities of building and running applications. We fundamentally believe that the future path forward for development is by providing a platform. In fact, as you’ll see in a few minutes, we believe that there are a number of new capabilities that should be delivered as services to the platform.Notes:There is a lot of confusion in the industry when it comes to the cloud. It’s important that you understand both what is happening in the industry and how we think about the cloud. This is the most commonly used taxonomy for differentiating between types of cloud services.The industry has defined three categories of services:IaaS – a set of infrastructure level capabilities such as an operating system, network connectivity, etc. that are delivered as pay for use services and can be used to host applications. PaaS – higher level sets of functionality that are delivered as consumable services for developers who are building applications. PaaS is about abstracting developers from the underlying infrastructure to enable applications to quickly be composed. SaaS – applications that are delivered using a service delivery model where organizations can simply consume and use the application. Typically an organization would pay for the use of the application or the application could be monetized through ad revenue. It is important to note that these 3 types of services may exist independently of one another or combined with one another.
- A periodic example may be a greenhouse thermometer. The devices may be configured to report hourly, and with some careful control of clock cycles you could predict exactly when traffic will arrive at your services. Ideally in such a case you’d only provision compute resources at a certain time so that you aren’t overpaying for resources. This is a perfect cloud scenario.A frequent retrieval may be a fridge that wishes to show the news headlines – it has to frequently poll, and this constant growth gives a fast per unit growth pattern to the traffic. This growth pattern is unlike a human computer growth pattern where there are rarely constant usage on the client side.When a Device interacts with humans, a far less predictable usage pattern emerges – if a device responds to milk being taken from it (in order to report a reorder request) then it depends how quickly a user is drinking their milk! Very hard to predict.When devices are reporting periodically and growing fast, a differnet pattern emerges – a predictable burst pattern where there is never a true off state.
- Slide Objectives:Provide broad overview of WA Mobile Services featuresSpeaking Points:WAMSBuild a cloud backend in minutes with no hassles, no deployments, no fearSupports Windows 8 client SDK, Windows Phone 8 SDK, iOS SDK Android coming soonDataStructured Storage with SQL DatabaseAutomatic service api generated for storageRich querying capabilityServer LogicAutomatic CRUD service api generatedAbility to author server logic that intercepts CRUD operation pipelineAuthAuthenticate against Windows LiveTable level authorization with no code More granular control with server side scriptsNotificationsIntegrates with WNS to provide Toast, Tile, Badge and Raw notificationsClean object model to compose notificationsSchedulerScheduler allows you to run Scripts to perform tasks at a scheduled basis minutes, hrly, daily, monthly or on demand.Example – aggregate News RSS feeds and send a tile update every 15 minutes Logging and Diagnostics for monitoringScale out and Scale up

- Slide Objectives:Explain the differences between traditional self-hosting and the three options of Windows Azure hosting.Notes:In a traditional environment you must manage the full stack. With Windows Azure you can choose a variety of options depending on your needs.
- Git Deployment is Native, or through a Service hook from CodePlex, GitHub or BitBucket
- Slide Objectives:Explain that Windows Azure Web Sites supports Classic ASP, ASP.NET, PHP, and Node.js out of the box and that you can also host any custom FastCGI handler.Notes:

- Slide ObjectivesUnderstand TablesSpeaker NotesThe Table service provides structured storage in the form of tables. The Table service supports a REST API that is compliant with the ADO.NET Data Services REST API. Developers may also use the .NET Client Library for ADO.NET Data Services to access the Table service.Noteshttp://msdn.microsoft.com/en-us/library/dd573356.aspx
- Slide ObjectivesUnderstand Flexible EntitiesSpeaker NotesTables store data as entities. A table can contain entities of any shapeThere is no fixed schemaThere is no schema checkingThere is no strong typing- not that Birthdate is stored as both a datetime value and as a stringNot that we can add additional columnsNoteshttp://msdn.microsoft.com/en-us/library/dd573356.aspx
- Slide Objectives:Define the Windows Azure storage and the great benefits this service providesSpeaking Points:The Windows Azure storage services provide storage for binary and text data, messages, and structured data in Windows AzureScalable DurableAvailableCostRESTGeo-redundant storage provides the highest level of storage durability by seamlessly replicating your data to a secondary location within the same regionLocally redundant storage provides highly durable and available storage within a single location. Microsoft monitors the service, provides patches, handles scaling, and does the other work needed to keep the service available.Notes:

- Speaking Points:This is a small sampling ..We’ve talked about a few of these building block services. In addition to Database, Storage, Caching, Messaging, and Identity…Big data - We also have services for managing big data…Traffic Manager - …Media Services - …Provides a managed service that allows you to create, manage, and distribute media. You can target any type of deviceWe’ll provide full analtyics on top of it. CDN – A content delivery network for putting your content closer to end users. We’ll drill into more details on several of these services later today and You will see this list grow in the months and weeks ahead
