Azure Roles

Running apps in a virtual machineA virtual machine can have 1,2,4 or 8 coresWe can have multiple instances of the VM runningThree types

Web Role = internet facing, IIS, request/response, ASP.NET or WCFWorker Role = background processing, endless loop, internal endpoints, can host WCF servicesVM Role = custom OS (W2008R2)

• WebRole– Hosting ASP.NET pages and/or WCF Services.– Handles incoming HTTP/HTTPS requests.– Public, Internet faced.– Has access to Storage Services.

• WorkerRole– Code running in background, processing jobs.– ‘Hidden’ processing power.– Similar to a batch job or Windows service.– Handles messages from a queue.– Has access to Storage Services.

Ability to upload your own customized WS2008R2 Enterprise imagesFull control over the OS image, install whatever you want on it.You can remote desktop into the OSTarget scenarios

Need to use apps/libraries with no unattended setup32 bits appsChange registry settings

Scale out !Instances are behind loadbalancer, one public IP per serviceNo durability of OS image on hardware failure

With VM Role, the customer creates & maintains the OSPaying model = Paying model of current web/workerroleUses differencing disks to upload deltas to image

Web/WorkerRole vs VMRoleAll three are virtual images running in the datacenter under control of the Azure fabric controller behind the loadbalancer.

Web/Worker RoleThe virtual image is already there, ... you upload your app, ... Azure places this app on the image and runs the image.

VM RoleYou upload the complete virtual image with all apps installed, ... Azure runs the image

CMS systems on Azure



CMS in Azure, why?

Paul Sterling [email protected] (Technical Lead)Azure solving the future issues of

•highly-scaled•widely distributed•very dynamic WCMS solutions

NOT a replacement for traditional hosting, but a new option

10 March, 2011



How much does it cost?

Simulation (approximate cost)1GB Azure SQL 10GB Blob storage (475000 read/write transactions/day)50GB download traffic, 5GB upload traffic

One webinstance: €86/month Two instances: €148/month Two instances + one staging: €210/month

ConclusionHosting websites on Azure = starting at €1.000€/year

Use Azure Pricing Excel to calculate!Demo?

10 March, 2011


WCMS in Azure

Azure is great forHigh traffic websitesSites where you need to quickly scale-up/downGlobal sites (visits many geo locations)Load balancing, stronger SLA’s

Azure is not ideal forLow cost hosting projectsProjects with lots of legacy code/dependencies

Umbraco v4.5+ in Azure: Challenges

What did we learn this morning?Group talk

10 March, 2011

67

Where does Umbraco store info?

SQL database: Page templates (no binaries, only references in DB)Page content (meta-data, texts, navigation nodes)Media/documents (no binaries, only reference in DB)Users & members, permissionsLogs (errors, actions in admin)

File storage: Page templates: .MasterScripts/styles: XSLT, CSS, JS, ... + design elements used in templatesUser controls: ASCX/DLLs + Umbraco binariesMedia: GIF, JPG, PDF, Videos, ...Config: web.config + /config/ xml files


68

Umbraco XML cache

XML file (/app_data/umbraco.config)Stored on local file systemContains all published nodes

PurposeFast app warm-up time (<1 sec)Less SQL queries – SQL is not used public site

Automatically updatedEvery time you publish using Umbraco backendXML dump of in-memory cache

Future: Umbraco v5

Beta expected Q2 2011 (April/May)RTM somewhere end 2011

Paul Sterling [email protected] (Technical Lead)With regard to Umbraco v5; the support for Azure will be native in the sense that the architecture takes into account the de-coupled scenarios possible in cloud-based computing - where your data store may be a database, a flat store, or a blob store - and the runtime may be in a single instance or in 1,000's of volatile instances.

If you are looking to leverage Azure for your solutions in the future, keep an eye on v5 as much of the architecture has been finalized and a usable code base is not too far off.

10 March, 2011



Umbraco v4.5+ in Azure, too early?

Yes, for most scenariosOnly one instance, quite complex

But it’s great to:Experiment with AzureBe ready for the future

Hands-on



Hands-on: web role + SQL

1. Install clean Umbraco site local laptop (using Web platform installer)

2. Provision Azure SQL storage3. Migrate locale SQL db to Azure SQL (using migration wizard)4. Create Visual Studio package of Umbraco site

(using CodePlex solution)5. Provision WebRole on Azure6. Publish solution to Azure Webrole (using Visual Studio)7. Test your site on http://mysite.cloudapp.net

It works, but we have no backups.

http://mysite.cloudapp.net/

http://mysite.cloudapp.net/


Hands-on part 2: add Blob storage

1. Provision Azure Storage account2. Download 3rd party tool

http://cloudberrylab.com

3. Upload of local Umbraco files to Azure Blob (using Cloudberry)

4. Deploy Generic webrole with startup tasks (using VS) Configure IIS site (host header) Configure Storage Account (container, account name, password)
