Worker Role Patterns• Queue Polling Worker– Poll and Pop Messages within while(true) loop– E.g. Map/Reduce pattern, background image processing

• Listening Worker Role– Create TcpListener or WCF Service Host– E.g. Run a .NET SMTP server or WCF Service

• External Process Worker Role– OnStart or Run method executes Process.Start()– Startup Task installs or executes background/foreground

process– E.g. Run a database server, web server, distributed cache

Virtual Machine Role• Provided to help you move applications to Windows Azure• Enables you to have full control over the OS Image

– Create your VHD locally– Upload the VHD to storage– Deploy a service package that uses the custom OS image– The role is your VM – Specify <OsImage href="20101020BaseVM.vhd" /> in the .cscfg

• Key considerations– Image must be Windows Server 2008 R2 Enterprise– Designed for long or non-automated installs– No durability of OS image– You configure and maintain the Operating System

• Currently available as a limited beta

How Windows Azure Drives Works

6-10-2011 12

• Drive is a formatted page blob stored in blob service

• Mount obtains a blob lease • Mount specifies amount of local

storage for cache• NTFS flushed/unbuffered writes

commit to blob store before returning to app

• NTFS reads can be served from local cache or from blob store (cache miss)

Loosely Coupled Workflow with Queues

6-10-2011 16

• Enables workflow between roles– Load work in a queue

• Producer can forget about message once it is in queue

– Many workers consume the queue– For extreme throughput (>500 tps)

• Use multiple queues• Read messages in batches• Multiple work items per message
