The windows azure platform
The Windows Azure Platform

  • Windows Azure

  • SQL Azure

  • Windows Azure platform AppFabric

  • Developer tools

  • Microsoft Codename “Dallas”


Windows azure on one slide
Windows Azure, On One Slide

  • The “cloud” is

    • 1000s of geo-distributed servers & networking

  • Windows Azure is analogous to

    • An operating system for the cloud

  • The “operating system by analogy” provides

    • Application hosting

    • Automated service management

      • Upload your code and “service model”; press START

    • Durable storage at massive scale

Windows azure in four bullets
Windows Azure, In Four Bullets

  • Programming model

    • “How do I write my applications in the cloud?”

  • Storage

    • “How do I store my data in the cloud?”

  • Service management

    • “How do I manage my assets in the cloud?”

  • Business

    • “How do I rely on the cloud?”



Principles
Principles

  • Create a familiar programming environment

  • Encourage best practices for the cloud

  • Net result: Lower TCO for customers


Flexible service architectures
Flexible Service Architectures

  • A service consists of

    • An isolation boundary

    • A set of component roles, each with endpoints

    • Numbered, identical instances of each role

  • All of this is specified in a service model


Flexible service architectures1
Flexible Service Architectures

  • A role instance is a set of code, configuration, and local data, deployed in a dedicated VM

    • Web Role: The role is hosted on IIS

    • Worker Role: The role is an executable (you can create your own web server, host a database, …)

Web

Role

Worker Role

Worker Role


Flexible service architectures2
Flexible Service Architectures

  • A service is reachable externally via a single VIP for load-balanced traffic to multiple endpoints

  • Endpoints are reachable internally over TCP, HTTP

    • (New) Runtime API exposes & updates IP/Port values

LB


Sample inter role communication
Sample: Inter-role Communication

  • // Use WA runtime API to find IP/Port of target endpoint

  • IPEndPoint endpoint =

    • RoleEnvironment.Roles[“HelloFabric_WorkerRole"].

    • Instances[0].

    • InstanceEndpoints["DayTime"].

    • IPEndpoint;

  • // Write standard code using the endpoint returned by API, e.g.

  • var client = new TcpClient();

  • client.Connect(endpoint);

  • var rd = new StreamReader(client.GetStream());

  • var test = rd.ReadToEnd();

  • client.Close();


Sample notification of new instances
Sample: Notification Of New Instances

  • // Handle new role instances in this callback

  • RoleEnvironment.Changed += (object sender,

  • RoleEnvironmentChangedEventArgs e)

  • {

  • // Iterate over the topology changes, if any

  • foreach (vartopoChange in

  • e.Changes.OfType<RoleEnvironmentTopologyChange>())

  • {

  • // Get the name of role whose instance count changed

  • string role = topoChange.RoleName;

  • // Get the new instances of the role

  • var instances = RoleEnvironment.Roles[role].Instances;

Developing Advanced Applications with Windows Azure

Thursday 11:30am

403AB


Principles revisited
Principles, Revisited

  • Create a familiar programming environment

    • Full trust: Support standard languages and APIs

    • (New) Secure certificate store in the cloud

    • ASP.NET providers

  • Encourage best practices for the cloud

    • (New) Logging and diagnostics system

    • Built-in service healing


Sample logging
Sample: Logging

  • // Register a new Trace provider in your web.config

  • // (automatically generated in Visual Studio templates)

    • <system.diagnostics>

    • <trace autoflush="false" indentsize="4"><listeners>

    • <add name="AzureDiagnostics" type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

    • </listeners></trace></system.diagnostics>

  • // Use standard tracing API to generate logs that are

  • // collected and pushed to Windows Azure Storage

  • Trace.WriteLine("This is a CRITICAL log", "Critical");

  • Trace.WriteLine("This is an INFORMATION log", "Information");

  • Manage services programmatically using the (New) Service Management API

    • Use in combination with diagnostics API to build a feedback loop


Full range of service upgrade models
Full Range Of Service Upgrade Models

  • (New) In-place rolling upgrade

    • Role instances are spread over update domains

    • Roles are updated one update domain at a time

    • Service remains available during upgrade

  • Real-time hot swap

    • Swap service endpoints of old/new version

    • Enables complex architectural changes

  • Planned downtime

    • Stop and replace service with new version

Automating the Application Lifecycle with Windows Azure

Thursday 10:00am

515B


Sample handling changes by recycling
Sample: Handling Changes by Recycling

  • // Handle new role instances in this callback

  • // This callback is invoked one update domain at a time

  • // So you can avoid the complexity of updating data structures

  • // by just using the runtime API to recycle the role instance

  • // Note this should be done before the change

  • RoleEnvironment.Changing += (object sender,

  • RoleEnvironmentChangedEventArgs e)

  • {

  • e.Cancel = true;

  • }

"In a matter of weeks, we were able to see the fruits of our efforts very rapidly."

"Integrating to our existing applications, that is what we really wanted to prove out that we could do."

"We will definitely leverage the Azure Platform in the future, the reason is it gives us a broad development platform, that we can really customize."


EsatSezer

Senior Vice President & CIO

"The resilience and reliability of this platform is some of the benefits that we are seeing."

"We are feeling very confident to deploy that into a large-scale base as our customers pulls this."
