Programming Model

Principles> Create a familiar programming

environment> Encourage best practices for the cloud

> Net result: Lower TCO for customers

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 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, …)

Worker Role

Worker Role

Web Role

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

// 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

// Handle new role instances in this callback

RoleEnvironment.Changed += (object sender, RoleEnvironmentChangedEventArgs e){ // Iterate over the topology changes, if any foreach (var topoChange 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;…

Applications with Windows Azure

Thursday 11:30am403AB

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

// 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");

SVC 15Windows Azure Monitoring

and Logging APIs

Wednesday 1:30pm408A

>>FUTUREComing Soon

> Easier migration of existing applications

> Greater control over cloud VMs

> Solutions:> Administrator privileges on cloud VMs> User-driven construction and

configuration, and platform deployment, of VM images

> Remote terminal server access to cloud VMs

Storage

Simple, Useful Storage Abstractions > Blobs

> Small to very large files, random read, chunked> (New) Random writes

> Tables> Partitioned, dynamic schema, entity sets> Batch transactions within a partition

> Queues> (New) Drives

> Use standard file system APIs to storage service> Available in February

SVC 09Windows Azure Tables and

Queues Deep Dive

Thursday 3:00pmPetree Hall C

Designed For The Cloud > For easy access, from anywhere

> Language agnostic REST APIs> Client libraries for .NET, Java, PHP, …

> For durability> All data is replicated 3 times within a

cluster, and (February) across datacenters

> For massive scale> Data is automatically partitioned and load

balanced across servers

>>FUTUREComing Soon

> Geo-replication> User-selectable geo-locations for replicas

> Tables> Secondary indices

Service Management

Lights-Out Service Management > Create services at the developer

portal> 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> (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

Session Alert !!

SVC 25Automating the Application

Lifecycle with Windows Azure

Thursday 10:00am515B

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."

Kevin Flowers Director of Enabling Technologies

Esat SezerSenior 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."
