Nivo 300 Anatomy of a Windows Azure Service Worker Role Web Role Web Role VM Role

Nivo 300 GOAL: SCALABLE, DURABLE STORAGE Windows Azure storage is an application managed by the Fabric Controller Windows Azure applications can use native storage or SQL Azure Application state is kept in storage services, so worker roles can replicate as needed Blobs: large, unstructured data (audio, video, etc) Tables: simply structured data, accessed using WCF Data Services Queues: serially accessed messages or requests, allowing web- roles and worker-roles to interact Storage in Windows Azure

Nivo 300 Windows Azure Platform Consumption Prices Access Control $1.99/10k transactions Per Message Operation $3.99/month per connection Per Message Operation Service Bus

Nivo 300 The Developer Tools Development Environment Vista+ Must enable local IIS features Visual Studio 2010 Must run as local Admin.NET 3.5 SP1 /.NET 4.0 Local SQL instance Azure SDK Provides local emulator Complete local simulation of the cloud fabric 90% of the local emulator is the same as the cloud fabric Includes handy project templates Deployment and management tools Includes client storage library

Nivo 300 Basic Roles

Nivo 300 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

Nivo 300 Comparison of 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. ControlControl Abstraction (i.e. Less IT & Less Plumbing Code) Abstraction Admin Web / Worker Role VM Role Web / Worker Role

Nivo 300 Operating System is provided by customer Patches are provided by customer Operating system is provided by Microsoft Patches are provided by Microsoft Compute Service Roles Web and Worker Role VM Role

Nivo 300 Compute Services Security Customer code run on dedicated virtual machines (VMs) VMs isolated by a Hyper-V based hypervisor All access to network and disk is mediated by a “root” virtual machine Hypervisor and “Sandbox” Hypervisor Network/Disk 1, 2, 4 or 8 CPUs, up to 14GB of memory Stripped down, hardened version of Windows Server 2008 Three virtual hard disks Limited number of device drivers Network connectivity restricted using host firewall Hyper-V based hypervisor

Nivo 300 Interacts with a “Fabric Agent” on each machine Monitors every VM, application and instance Performs load balancing, check pointing and recovery Fabric Controller Web Role Instance Worker Role Instance VM Role Instance

Nivo 300 What is the web role? A web role hosts an IIS based web site or service. Supports HTTP, HTTPS and certificates Automatically load balanced by Azure Can be internal only, but usually public facing Runs on IIS7 Usually runs an ASP.NET site.

Nivo 300 Full IIS – Overview Web Role will now use full IIS by default One Web role can run many Web sites, all hosted behind the same public IP address Multiple sites, applications, virtual directories, and bindings can be modeled Everything else can be scripted (using admin access where necessary)

Nivo 300 Full IIS Scenario - Walkthrough PhaseKey Steps Local Development Use Visual Studio solution to code & deploy to Compute Emulator Edit local content files without redeploying to Compute Emulator First-time Publish (~10 Min) Deploy service to Windows Azure Ensure Windows Azure service definition (csdef/cscfg) configures Web role: To enable remote WMSVC, WebDeploy, PowerShell, etc. As single instance Iterative Development (seconds) Continue coding in same Visual Studio solution Push intermittent changes (e.g. w/ Web Deploy) Deployment of Final Version (~10 Min) Deploy service to Windows Azure Note: If service is now multi-instance, Remote Desktop can be used, but other remote mgmt. tools will get load- balanced to arbitrary instances. Mitigation: Run mgmt. tools inside Remote Desktop session

Nivo 300 What is a worker role?.NET 3.5 sp1 / 4.0 Focused on backend processing and non-HTTP service hosting By default, does not allow inbound connections

Nivo 300 Role Programming Model Inherits RoleEntryPoint OnStart() Method Called by Fabric on startup, allows you to perform initialization tasks. Reports Busy status to load balancer until you return true. Run() Method Main logic is here – can do anything, typically infinite loop. Should never exit. OnStop() Method Called when role is to be shutdown, graceful exit. 30 Seconds to tidy up

Nivo 300 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 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

Nivo 300 What is the VM Role Developers have full control over the OS image Ability to upload your own customized WS08R2 Enterprise images Operators can reboot, re-image and Remote Desktop Continue to benefit from automated service management, including service model enhancements described on subsequent slides

Nivo 300 VM Role Lifecycle Cloud On-Premises Blob Storage Boot VHD Customize VHD Save Diff.VHD Base.VHD Identical/similar deployment instances using common uploaded OS image (base.VHD + diff.VHD) & Additional Software & Windows Azure Integration Components - Agent - Runtime Interface (topo, config, shutdown notification, …) - Remote Desktop configurator - Diagnostics - Windows Azure Drives driver - Windows Azure Connect & Generalize (Recommended)

Nivo 300 VM Role – Common Questions Will any WS08 R2-based application work? No, VM Role inherits some Web/worker restrictions: SLA requires at least two identical/similar instances No durability of OS image on hardware failure One public IP per service (unless using Windows Azure Virtual Network) Does Windows Azure take care of *everything*? No With VM Role, the customer creates & maintains the OS Windows Azure does not automatically understand the health of the applications running in our VM But, since you deploy services instead of individual VM’s, Windows Azure does automate many management tasks.

Nivo 300 VM Role – Common Questions How will it be priced? It will be priced the same as Web and Worker roles. Customers will be charged at an hourly rate depending on the compute instance size. How does licensing in the cloud work? Windows: Included in the CPU-hour price Licensing status of uploaded image is not considered Applications: Per the licensing terms of the application

Nivo 300 Instances An instance is a physical implementation of your role template. There are different sizes of instances, but all instances of a role must be the same size. You can not change instance size on the fly.

Nivo 300 SQL Express? If you have SQL Express the storage emulator will auto-configure on the first run If you want to use a different SQL instance: DSInit /sqlInstance:.

Nivo 300 Are we running in the fabric?

Nivo 300 Debugging in the cloud? No. No debug for you.

Nivo 300 Debugging locally You can debug locally just like a normal ASP.NET application. Full support for multiple instances.

Nivo 300 Support for IntelliTrace IntelliTrace now supported in Windows Azure Integrated into VS2010 Ultimate Requires.NET 4 applications Deploys an agent to your instances Gathers and reports all debugging stack information Can replay the app locally

Nivo 300 Support for Profiling Easily detect performance bottlenecks in your application while its running in Windows Azure. Choose “View Profiling Report” Open shortcut menu for instance to profile Profiling report is retrieved from Windows Azure After report is downloaded, it is displayed

Nivo 300 Hello Cloud

Nivo 300 Three Choices to Deploy Code Visual Studio Portal Script/Management API

Nivo 300 Deploying to the cloud You must create an Azure account, then a service, and then you deploy your code. VS builds two files. Encrypted package of your code Your config file Can take 20 minutes (which is better than six months) In a dev scenario, you can use Web Deploy

Nivo 300 Portal

Nivo 300 Visual Studio Publishing Fast publishing direct from Visual Studio Uses.publishsettings file (like Web Matrix) Wizard uses Windows Live ID credentials to download file Auto-generation of X509 certificate Base64 encoded certificate in.publishsettings Subscription ID and name of each subscription linked to that Windows Live ID. Publishing will add new X509 certificate and your package to Windows Azure.

Nivo 300 Visual Studio Publishing

Nivo 300 Deploying to the cloud

Nivo 300 DNS All services get a *.cloudapp.net address myservicename.cloudapp.net TTL is 10 seconds Standard approach is to CNAME to *.cloudapp.net Requires two DNS lookups Limited caching due to low TTL Officially we do not support the use of A records IP Address for deployment is fixed for lifetime of that slot

Nivo 300 Advanced Roles

Nivo 300 Admin Access & Startup Tasks Scenarios Perform short, unattended setups on role startup. E.g. COM Component Registry Key Configuring a Windows Server Role, such as IIS Debugging Reminders Durability: Runtime state on OS image does not survive OS upgrade and hardware failure Drift: Service should behave correctly when any role instance fails

Nivo 300 Admin Access & Startup Tasks <Task commandline="relative\path\ToSetupExecutable" executionContext="limited|elevated" taskType="simple|foreground|background"/> Task Types: Simple [Default] – System waits for the task to exit before any other tasks are launched Background – System does not wait for the task to exit Foreground – Similar to background, except role is not restarted until all foreground tasks exit

Nivo 300 Startup tasks

Nivo 300 Local Storage Each role can define an amount of local storage. Protected space on the local drive. Considered volatile storage. You can define several resources. Size is between 1MB and 20GB+. Defined in.csdef.
