Windows Azure AppFabric is a platform that provides middleware services for developing and managing cloud applications at scale. It includes services for messaging, caching, identity management, and integrating applications. It also allows building and managing composite applications composed of distributed application components hosted on Windows Azure. The AppFabric platform aims to simplify cloud development by providing these services and capabilities through a consistent programming model.

6. AppFabric Service Bus The Service Bus provides secure messaging and connectivity capabilities that enable building distributed and disconnected applications in the cloud, as well hybrid application across both on-premise and the cloud. It enables using various communication and messaging protocols and patterns, and saves the need for the developer to worry about delivery assurance, reliable messaging and scale. Expose RESTful or SOAP services over the internet through firewall and NAT boundaries Communicate bi-directionally between apps and services in an interoperable manner Choose relays, queues, routers, and other message patterns and types Scale out naturally and reliably as apps and services grow

7. AppFabric Service Bus Core Capabilities Service location and discovery Simple registry Access via lightweight ATOM protocols from any platform Endpoint naming and discovery Cloud based messaging relay Allows bridging across NATs and Firewalls Connect apps without altering the network topology Network Listen/Send from any Internet-connected device Standards based HTTP or High Performance TCP Direct connection functionality using NAT probing

15. AppFabric Caching Caching provides a distributed, in-memory, application cache service for Windows Azure and SQL Azure applications. It provides applications with high-speed access, scale, and high availability, to application data. These capabilities are provided entirely as a service (no installation or management of instances, dynamically increase/decrease cache size as needed). Highly scalable caching solution with low latency and high throughput Provided entirely as a service - no installation or management of instances required Flexible management - dynamically increase/decrease cache size as needed Integrates easily with existing ASP.NET web applications

18. AppFabric Integration Integration provides common BizTalk Server integration capabilities (e.g. pipeline, transforms, adapters) on Windows Azure, using out-of-box integration patterns to accelerate and simplify development. It also delivers higher level business user enablement capabilities such as Business Activity Monitoring and Rules, as well as self-service trading partner community portal and provisioning of business-to-business pipelines Out-of-box integration patterns to accelerate and simplify development Simplify and automate interoperability with third-party applications to reduce redundancy, costs and errors Gain better visibility across end-to-end business processes and performance Promote agility and manageability

19. AppFabric Composite App Composite App provides a multi-tenant, managed service which consumes the .NET based AppFabric Composition Model definitions and automates the deployment and management of the end-to-end application. It executes application components to provide a high-performance runtime optimized for cloud-scale services and mid-tier components. It also delivers a complete hosting environment for web services built using WCF (either natively developed or using WCF Data Services and WCF RIA Services) and workflows built using WF. Build highly scalable and available composite applications composite applications consisting of AppFabric services as well as other mid-tier components Build applications distributed between on-premises and Windows Azure Automates the deployment and management of the end to end application Easier configuration and control of entire application and individual components End-to-end application monitoring (events, state, health and performance SLAs)

20. AppFabric Composite App Visual design experience AppFabric delivers a new Visual Studio based designer experience that allows you assemble code from your existing application components along with newer cloud services and tie them together as a single logical entity. It also enables you to use visual tools to deploy, manage and monitor the application running in Windows Azure

21. AppFabric Container Scale-out application infrastructure The AppFabric Container provides base-level application infrastructure such as automatically ensuring scale out, availability, multi-tenancy and sandboxing of your application components. Composition Runtime The AppFabric Container manages the full lifecycle of an application component. It also supports configurations like auto-start and on-demand activation of components, and provides support for setting and modifying component configurations dynamically. It also provides support for cross-cutting aspects like throttling, metering, logging, etc. Sandboxing and Multi-tenancy The AppFabric Container enables high-density and multi-tenancy of hosted components. The container captures and propagates the tenant context to all the application and middleware components. State Management The AppFabric Container provides data and persistence management for hosted application components. Scale-out and High Availability The container provides scale-out by allowing application components to be cloned and distributed; for stateful components, the container provides scale-out and high availability using partitioning and replication mechanisms. The AppFabric Container shares the partitioning and replication mechanisms of SQL Azure. Dynamic Address Resolution and Routing In a fabric-based environment, components can be placed or reconfigured dynamically. The AppFabric Container automatically and efficiently routes requests to the target components and services. AppFabric Container Multi-tenant, high-density, scaled-out host Composition runtime
