- 1. Developing Applications for Windows Azure Platform Sudheer Dhulipalla Microsoft Corporation
- 2. Assumptions • You’re comfortable building .NET apps using Visual Studio • You’re relatively new to Windows Azure or have recently started building Windows Azure apps
- 3. Agenda WHO WILL BENEFIT FROM TOPICS WHAT YOU’LL LEAVE WITH THIS TALK • Cloud application • Windows Azure Basics • Building applications developers with Windows Azure • Code Walkthroughs Platform • Developers building on- premise .NET and non • ASP page in the cloud • Azure platform .NET applications capabilities leveraging cloud services • WCF service in the cloud • Web and Worker sample • Service Bus Queues • Service Bus Topics • Relay service sample
- 4. Windows Azure • Microsoft’s cloud platform – Applications platform in the cloud that allows Microsoft datacenters to host and run applications • Windows Azure is Designed for: – Incremental Scalability – Reliability, high availability and fault tolerance – Developer agility and open standards (HTTP REST) – Utility based (pay as you go) – Cost effective based on sharing of resources – Service Oriented – SLA driven
- 5. What is Windows Azure? QUEUE
- 6. Windows Azure Development • Any tools, any languages (VS and .NET common) • Develop and test locally, publish to cloud • Applications consist of roles (components) – Web Role, Worker Role, VM Role – Run on VMs – Scaled/upgraded independently • Flexible storage options – SQL Azure – Blobs – Tables – Queues
- 7. Windows Azure App - Typical Architecture Web Worker LB Role Role
- 8. Windows Azure Storage • Abstractions – Blobs – File system in the cloud – Tables – Massively scalable structured storage – Queues – Reliable storage and delivery of messages – Drives – Durable NTFS volumes for Windows Azure applications • Easy client access – Easy to use REST APIs and Client Libraries – Existing NTFS APIs for Windows Azure Drives
- 10. Code Walkthrough - Sample #1 • Publishing a simple ASP page to Azure cloud – SDK and Tools setup – Portal sign up – Creating an ASP.NET WebRole project – Publishing the web page and accessing from local Azure Cloud Web Role Local Browser Running ASP Page
- 11. Code Walkthrough - Sample #2 • Publishing a WCF service in the cloud – Creating a WCF service WebRole project – Publishing the service and accessing the service operations from a local console application Azure Cloud Web Role Running Local Console App WCF Service
- 12. Code Walkthrough - Sample #3 • Publishing a project with web / worker roles – Web role hosting a web page – Worker role hosting a WCF service – Web to worker communication over TCP – Local debugging and Dev Fabric Azure Cloud Web Worker TCP Role Local Browser Role running Running WCF ASP Page Service
- 13. Windows Azure lets you manage applications, not virtual machines.
- 14. WINDOWS AZURE SERVICE BUS (A MESSAGING SERVICE IN THE CLOUD)
- 15. Brokered Messaging Entities: Queues Queue • Durable Queues • Scheduled messages • Session based message streams • Transactions support • Sequential Message Log • HTTP / REST / WCF / .NET API support
- 16. Code Walkthrough - Sample #4 • Service Bus Queues – Creating namespace – Importing credentials – Send / receive messages using Service Bus Queues from local machine Azure Cloud Service Bus Queue
- 17. Brokered Messaging Entities: Topics Sub Topic Sub Sub • Durable topics and subscriptions • Sequential Message Log • Multiple subscribers over the log, each with own cur/locks • Subscribers can filter with rules and expressions on message properties • HTTP / REST / WCF / .NET API support
- 18. Code Walkthrough - Sample #5 • Service Bus Topics – Creating topics and subscribers – Send messages to topic and receiving from multiple subscribers Azure Cloud Service Bus Sub Topic Sub Sub
- 19. Summary • Windows Azure is a powerful cloud applications development platform • Developers can use Visual Studio, .NET frameworks, Cloud Services, other languages and frameworks of their choice to build cloud applications and services • You can sign up for free trial today at http://windowsazure.com and start building cloud applications with Windows Azure
