Cloud ?

What is cloud computing ?Offering infrastructure, platform and software as a service over the internet to a global market.Move on-premises management of non functional IT assets to a providor.

Difference from traditional hostingsSold on demand “pay as you grow”Elastic scalabilityService is fully managed by the providorEnd user centric (IW or developer)Strong focus on integration (cloud-cloud or cloud-on-premises)

Todays challenges

Infrastructure Utilization

Infrastructure Complexity

70percent of datacenter capacity is idle on average

percent of IT budgets is spent maintaining datacenter operations

infrastructure as a service (hardware)Servers available in the cloud

platform as a service (developer) Delivery of a OS for custom, cloud enabled appsSupport for service hosting and interoperability Relational data storage in the cloud

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 runningTwo types

Web Role = internet facing, IIS, request/response, ASP.NET or WCFWorker Role = background processing, endless loop, internal endpoints, can host WCF services

• 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.

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

Azure Storage

Non SQL dataUnlimited storage4 types

Tables: no fixed schema, no relationsBlobs: large objects, have metadata attributes, MIME type awareQueues: assync communication to workerroleDrives: NTFS volume mounted to roles

Accessible through a HTTP/REST API

Windows Azure Storage Account

User creates a globally unique storage account name.

Storage keeps being available, even when application is not running !

Azure Tabless

Tables store entities.Entity schema can vary in the same table. Can Not :

Create foreign key relationships between tables.Perform server side joins between tables.Create custom indexes on the tables.No server side Count(), for example.

Azure Storage Blobs

Large dataCan be made private or publicCan have metadata attributes and MIME typesCan be cached by a Azure Content Delivery Network (CDN)Time based access to blobs with shared access signaturesTwo Types

Block Blobs : max 200GB, Use for data which is streamed back to a worker or client Page Blobs : max 1TB, Use for data accessed frequently by random reads and writes.

Azure Drives are also blobs

CMS systems on Azure

CMS in Azure, why?

Paul Sterling paul@umbraco.com (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

How much does it cost?

Simulation (approximate cost)1GB Azure SQL 10GB Blob storage (1000000 read/write transactions/day)50GB download traffic, 10GB upload traffic

One webinstance: €77,01/month (promo offer €52,71) Two instances: €140,91/month (promo offer €94,78) Two instances + one staging: €204,81/month (promo offer €136,85)

ConclusionHosting websites on Azure = starting at €635/year

Umbraco in Azure

Umbraco v4.5+ in Azure: Challenges

What did we learn this morning?What are the challenges to host a CMS in Azure?

Group talk

24 June, 2011

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

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

http://forum.umbraco.org/yaf_postst4161_Umbraco-caching-explained.aspx

Challenges

Multiple instances of the web-roleRound-robin load-balancingSessions need to be stored centrally

StorageNo local storage (unsafe)No “shared drive” over multiple machines

CDN – Content Delivery NetworkOnly possible when files are stored on Azure Blobs

Custom codeNeeds to work within the boundries of Azure

Solutions to host Umbraco v4.5+ on Windows Azure

1. Simple web-role (manual creation)

2. CodePlex accelerator (by Slalom Consulting)

CodePlex Accelerator by Microsofthttp://waacceleratorumbraco.codeplex.com

How does the Accelerator work?Creates 1 or more web-role instances (VMs)

•deploys a sync IIS process on these machinesDeploy tool uploads complete Umbraco installation to Blob Storage

•Includes all the files: images, css, aspx, web.config, …Created SQL Azure database for session stage

•Auto configuration of web.configScripts keeps local file system in sync with the blob storage

•Every second•Bi-directional

Uuser adds file trough Umbraco cms, is stored on local filesystem of the current web-role

One second later, file is pushed to Azure Blob StorageOne second later, file is pulled to the other web-roles

Future: Umbraco v5

CTP Released last week (available on CodePlex)http://umbraco.codeplex.com

Beta expected Q4 2011RTM somewhere end 2011 - beginning 2012

Paul Sterling paul@umbraco.com (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.

24 June, 2011

Umbraco v4.7+ in Azure, too early?
