Hello World! .
Cloud Service Overview
What is a Cloud Service?
A collection of related service roles
Web Role Worker Role VM Role
Web Role
All features of a worker role + IIS 7 or 7.5ASP.NET 2.0 3.5 SP1 or 4.0HostsWebforms or MVCFastCGI applications (e.g. PHP)Multiple Websites
Http(s)Web/Worker HybridCan optionally implement RoleEntryPoint
Worker Role Patterns
Queue Polling WorkerPoll and Pop Messages within while(true) loopE.g. Map/Reduce pattern, background image processing
Listening Worker RoleCreate TcpListener or WCF Service HostE.g. Run a .NET SMTP server or WCF Service
External Process Worker RoleOnStart or Run method executes Process.Start()Startup Task installs or executes background/foreground processCustom Role Entry Point (executable or .Net assembly)E.g. Run a database server, web server, distributed cache
Roles and Instances
At runtime each Role will execute on one or more instances A role instance is a set of code, configuration, and local data, deployed in a dedicated VM
Roles are defined in a Hosted ServiceA role definition specifies:Virtual machine sizeCommunication endpointsLocal storage resourcesetc.

What’s dedicated cache?
• Use spare memory on your VMs as high-performance cache
• Distributed cache cluster co-located with existing roles, or use dedicated roles
• Named caches with high availability option
• Notifications• Support Memcached protocol
Why dedicated cache?
FasterNo external service calls (additional network hops)Co-located in roles
CheaperNo external service calls (additional cost)Use spare memory that you already paid for
More reliableYour service is running = cache is availableNo throttling as in cotenant environment
