What is Windows Azure Platform ?• The Windows Azure platform is an internet-scale cloud computing services

platform hosted in Microsoft data centers.

• Provides a range of functionality to build applications that span from consumer Web to enterprise scenarios.

• The Windows Azure platform includes:• Windows Azure• SQL Azure• Windows Azure AppFabric


What is Windows Azure ?

• Windows Azure serves as the development, service hosting and service management environment for the Windows Azure platform.

• Provides developers with on-demand compute, storage and content delivery network capabilities to host, scale and manage Web applications on the Internet through Microsoft data centers.

• Windows Azure is now commercially available in 41 countries.

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

– Front end: e.g. load-balanced stateless web servers– Middle worker tier: e.g. order processing, encoding– Backend storage: e.g. SQL tables or files– Multiple instances of each for scalability and availability

Role EnhancementsAdditional control and flexibility on the Windows Azure environment and simplified migration of existing Windows applications to Windows Azure.

• Windows Server 2008 R2 & IIS 7.5• Admin Access: Full administrative access to your role instances• Reboot/Re-image support: Ability to easily reboot or re-image your instances• Remote Desktop: Ability to use Remote Desktop with any Role type (Web, worker, VM)• Network Modeling

• Well Known Ports: Easier to bring your existing applications to Windows Azure• Port Ranges: for “inbound traffic” (as opposed to 5 in the past)• Load Balancer Control: Take instance on/off the load balancer for debugging purposes• Network Filters: Enable traffic filtering between roles within a service

• Improved AutomationStartup Tasks: Includes 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. More samples to come)


Full IIS Support

• Leverage the ecosystem of IIS applications, programming languages tools, and components with the revamped Web role

• Multiple Web sites and applications• Improved iterative local development with the Development Fabric• Iterative cloud development with Web Deploy and IIS Manager• Host level configuration, including native modules• Enhanced by Windows Azure automated service management


Web & Worker Roles


Web Role

• Customized for Web application development• Driven by UI , User Interaction• May define a single http/https end points (Input endpoint) for communication

with external clients• Can communicate with other roles (Internal endpoint) with a single http

endpoint


Worker Role

• For generalized development• Performs background processing• May define a any number http/https / TCP end points (Input endpoint) for

communication with external clients• Can communicate with other roles (Internal endpoint) with a any number of

http/TCP endpoint

• Windows Azure SDKs 1. Development Simulation of Fabric Controller2. Development Simulation of Storage Service3. DLLS

• Microsoft.WindowsAzure• Microsoft.WindowsAzure.Diagnostics• Microsoft.WindowsAzure.ServiceRuntime.dll• Microsoft.WindowsAzure.StorageClient.dll

Key PointsVirtual Tech Days


• Windows Azure Tools for Visual Studio1. New template for Cloud Applications

• Web Role (asp.net, MVC, WCF service), Worker Role• C#, VB.net ,F#(For worker role)

2. Service Model governed by Roles & completely configurable3. Web & Worker roles tooling

• WebRole.cs & WorkerRole.cs• Diagonostic trace enabled• Appropriate References Added

4. Visual Studio integration of Build, debug & deploy to Cloud simulator5. Enhanced one click publish to the Cloud with certificates

Key pointsVirtual Tech Days


6. Server Explorer has Windows Azure Compute & Storage tabsa. Compute can directly connect to the cloud on on-clickb. Storage can connect to dev-storage or cloudc. Storage can be filtered and manage huge amounts of data

7. Windows Azure activity loga. Compute analysesb. Storage analysisc. Trace

8. IntelliTrace enables historical debugging of Read cloud scenario on your desktop

Key PointsVirtual Tech Days


– Using Configuration, Its easy to scale UP /Down in Azure– Understand how Web & Worker Roles Communicate with Each Other– Strategy on when to scale up and scale down in production– Real Time scaling is available
