3 Agenda Windows Azure Compute Model and Terminology Service Definition Data are always part of the game. 3 Windows Azure for developers

4 Windows Azure Compute Windows Azure is a foundation of Microsoft s Cloud Platform for Developers Operating System for the Cloud Runs applications in the cloud Provides Storage Application Management Developer SDK 4 Windows Azure for developers

5 Storage Cluster Compute Cluster Windows Azure in a Slide Business Portal REST Developer Portal Service Management Service User Code Runtime API VM Setup VS Tools WA SDK Desktop REST MSFT Datacenters Cloud VM 5 Windows Azure for developers

6 Windows Azure Compute features Windows Server 2008 / R2 (64bit).NET 3.5 SP1 and.net 4.0 Full Trust* IIS Web Sites (ASP.NET, FastCGI) Web Services (WCF) Stateless Servers Http(s), TCP 6 Windows Azure for developers

7 Windows Azure Tooling Windows Azure Tools for Visual Studio Visual Studio 2008 Visual Studio 2010 Project Templates Model & Config Tooling Package & 1 Click Deploy Debugging Support Storage Explorer Server Explorer IntelliTrace Support Windows Azure SDK Windows Server 2008 or Windows 7 SQL Express NET 3.5 SP1+ Development Fabric Development Storage.NET APIs 7 Windows Azure for developers

8 Visual Studio Tooling Project Template for Cloud Services ASP.NET Web Role ASP.NET MVC 2/3 Web Role WCF Service Web Role Worker Role CGI Web Role Integration with development fabric IntelliTrace for Windows Azure Deploying to Azure Cloud from within Visual Studio 8 Windows Azure for developers

9 Project Structure For every role you get an own project Special Azure Deployment Project Two important configuration files Service definition file Service configuration file 9 Windows Azure How to get started

10 Development fabric Simulates the Windows Azure fabric on your local computer Is free. You will not be charged from MS The development fabric UI enables you to debug your services locally No Access Control Service No Service Bus 10 Windows Azure for developers

11 Development Fabric UI 11 Windows Azure for developers

12 Demo (1) Hello Windows Azure Data are always part of the game. 12 Windows Azure for developers 12

13 Windows Azure Service Architecture The Internet via TCP or HTTP L B L B L B Web Web Site Site Web Role (ASPX, (ASPX, IIS ASMX, WCF) ASMX, as Host WCF) Queues Tables Storage Blobs Worker Worker Role Service Managed Interface Call Windows Azure Data Center 13 Windows Azure for developers

15 Subscriptions and Services A subscription contains a collection of up to 6 services Determines the billing model May include a level of bundled usage A service consists of An isolation boundary and a public URL A set of component roles (up to 5), each with endpoints At runtime one or more identical instances of each role Services are defined in a service model 15 Windows Azure for developers

16 Roles and Instances Roles are defined in a Service Model May define one or more Roles per Service A role definition specifies VM size Communication Endpoints Local storage resources etc. At runtime each Role will execute on one or more instances (up to 20 per subscription) A role instance is a set of code, configuration, and local data, deployed in a dedicated VM 16 Windows Azure for developers

17 Role Types 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, ) VM Role : The role is the VM. Use Windows services, scheduled tasks, etc. You configure and maintain the OS. Web / Worker Role Admin Web / Worker Role VM Role 18 Abstraction (i.e. Less IT & Less Plumbing Code) Windows Azure for developers Control

18 Roles and Instances (2) Service Virtual Machines Web Role Picture Portal (4 Instances) Web Role Instance 1 Web Role Instance 2 Web Role Instance 3 Web Role Instance 4 Worker Role Image Resizing (8 Instances) WorkerRole Instance 1 WorkerRole Instance 5 WorkerRole Instance 2 WorkerRole Instance 6 WorkerRole Instance 3 WorkerRole Instance 7 WorkerRole Instance 4 WorkerRole Instance 8 19 Windows Azure for developers

19 Role Lifecycle Fabric Calls OnStart Run OnStop Role Lifetime Busy Ready Busy Requests Routed 21 Windows Azure for developers

20 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 22 Windows Azure for developers

21 The High Scale Application Archetype Intelligent Network Load Balancer Network Activation Stateless Worker Machines Stateless Web and/or Application Servers Async Activation State Tier Queues Key/Value Datastores Partitioned RDBMS Shared Filesystem 23 Windows Azure for developers

23 Understanding Packaging and Config Windows Azure Services are described by two important artifacts: Service Definition (*.csdef) Service Configuration (*.cscfg) Your code is zipped and packaged with definition (*.cspkg) Encrypted(Zipped(Code + *.csdef)) == *.cspkg Windows Azure consumes just (*.cspkg + *.cscfg) 25 Windows Azure for developers

24 Service Definition Describes the shape of your Windows Azure Service Defines Roles, Ports, Certificates, Configuration Settings, Startup Tasks, IIS Configuration, and more Can only be changed by upgrades or new deployments 26 Windows Azure for developers

25 Service Configuration Supplies Runtime Values (Scale, Config Settings, Certificates to use, VHD, etc.) Can be updated any time through Portal or API 27 Windows Azure for developers

26 VM Size in Windows Azure Compute Windows Azure Supports Various VM Sizes Size set on Role in Service Definition Balance of Performance per node vs. High Availability from multiple nodes Set in Service Model definition All instances of a role will be of equal size Size CPU Cores RAM Local Storage Extra Small Shared 768M 20GB Small 1 1.7GB 250GB Medium 2 3.5GB 500GB Large 4 7GB 1000GB Extra large 8 15GB 2000GB

27 Local Storage Role instances have available disk storage Use LocalStorage element in service definition Name CleanOnRoleRecycle Size Persistent but not guaranteed durable Good for cached resources 30 Windows Azure for developers

28 Networking in Windows Azure Compute 3 types of Endpoints in Windows Azure Input (VIP) Internal Windows Azure Connect* TCP only* 31 Trivadis the company

29 Configuration Values Store arbitrary configuration string values Define in model Populate in configuration RoleEnvironment.GetConfigurationSettingValue() Don t use web.config for values you wish to change at runtime App/Web.config is packaged with deployment change requires redeploy *.cscfg supports change tracking and notification to running role instances 32 Windows Azure for developers

30 Handling Config Changes RoleEnvironment.Changing Occurs before configuration is changed Can be cancelled causes a recycle RoleEnvironment.Changed Occurs after config change has been applied RoleEnvironmentConfigurationSettingChange Provides config value that was changed RoleEnvironmentTopologyChange When role count is changed 33 Windows Azure for developers

31 Managing, Debugging, Monitoring Windows Azure Applications Gerry Keune December 19, 2011 Basel Bern Lausanne Zurich Düsseldorf Frankfurt/M. Freiburg i. Br. Hamburg Munich Stuttgart Vienna

32 Agenda Managing Debugging Monitoring Data are always part of the game. 35 Windows Azure for developers

33 Your Service Management API Portal REST API 36 Windows Azure for developers

34 Deployment Environments Two nearly identical Environments to choose from Production (<servicename>.cloudapp.net) Staging (<deploymentid>.cloudapp.net) 37 Windows Azure for developers

35 Deploying Services Delete/Create Deployment Visual Studio does this VIP will change Service Model Updates don t matter VIP Swap Bring up another environment in Staging and swap Only Input Endpoints (external ports) matter In-Place Upgrade Rolling upgrade across roles Most restrictive on changes (no size, endpoints, roles, etc.) Web Deploy 38 Windows Azure for developers

36 VIP Swap Worker Role Load Balancer: Prod Stage Worker Role VM VM VM VM 39 Windows Azure for developers

37 In Place Upgrade Load Balancer: #1 Web Role Web Role #2 #1 Worker Role Worker Role #2 40 Windows Azure for developers

38 Deployment and Management Tools Visual Studio Windows Azure MMC Windows Azure Service Management (WASM) cmdlets 3 rd Party tools 42 Windows Azure for developers

39 Monitoring Windows Azure Diagnostics Windows Azure Monitoring MP for SCOM Monitors Health, Scales, and more 44 Windows Azure for developers

40 Windows Azure Diagnostics You can monitor the following: IIS Logs, Crash Dumps, FREB Logs Arbitrary log files Performance Counters Event Logs Debug/Trace statements Infrastructure events 45 Windows Azure for developers

41 How does it work? Role Instance Starts Diagnostic Monitor Starts Monitor is configured Imperatively at Start time Remotely any time Monitor buffers data locally User can set a quota (FIFO) User initiates transfer to storage Scheduled or On Demand Role Instance Role Local directory storage Diagnostic Monitor 46 Windows Azure for developers

42 Storage Considerations Standard costs apply for transactions, storage & bandwidth Data Retention Local buffers are aged out by the Diagnostic Monitor according to configurable quotas You control data retention for data in table/blob storage Dedicated or multiple storage accounts might be a good idea Query Performance on Tabular Data Partitioned by high-order bits of the tick count Query by time is efficient Filter by verbosity level at transfer time 48 Windows Azure for developers
