    • Understanding the Windows Azure Platform David Gristwood Application Architect, Microsoft blogs.msdn.com/david_gristwood
    • Why a Cloud Platform?  Reduce capital & operations costs  Simplify application deployment & management  Simplify scaling to internet scale  Cost effectively handle peak loads  Focus on new functionality & not infrastructure
    • The Azure Philosophy
    • Windows Azure is about Scale • Windows Azure is designed from the ground up for true Internet scale • Global presence • Ride the “network effect” • LinkedIn: 16 months for first million users, 11 days for most recent million • Facebook: 5 years to hit 250m users, 8 months to double • Scale up and scale down • Supports the “Scale Fast, Fail Fast” model www.flickr.com/photos/ScroffTheBad
    • Application Characteristics “Scale & Elasticity” • Need massive scale • target.com • walmart.com • Social networking, web 2.0 • toysrus.com • barnesandnoble.com • Need high reliability • LOB, software as a service • Have variable load / unpredictable ~4x normal load lifetime (Holiday shopping) • Ticketing, marketing • Parallel processing • Financial applications • Don’t fit in well with a company’s data center • Avoid IT dept, joint ventures Jan 2009 Jan 2010 • Benefit from external storage • Archive Source: Alexa http://www.flickr.com/photos/39919537@N06/3666813048/
    • Helps your Systems Scale • Most architecture is hidden inside code • Windows Azure encourages you to define your application into constituent parts • Windows Azure can scale the parts of your application as appropriate www.flickr.com/photos/39818355@N00/2128626176
    • Flexible Architecture • Systems evolve over time • Cloud is not an “all or nothing” proposition • Windows Azure makes it easier to extend to the cloud www.flickr.com/photos/tomkpunkt/3695066577
    • Opening up the Cloud • Allow developers to apply their existing skills to the cloud • Support for .NET, Ruby, PHP, Java • Interoperability with any platform, tools or technology www.flickr.com/photos/h19/2306213399/in/set-72157594224557858
    • Natural Platform Evolution • Windows Server 2008 • Virtualisation • Windows Services, such as IIS, logging, diagnostics, etc • Visual Studio & .NET
    • Flexible Business Model • No up front hardware purchase • Pay as you go costing model • Ideal in current economical climate www.flickr.com/photos/cleebster/2508660124
    • Azure Adoption
    • Azure is Live….. http://www.liveonazure.com/
    • Managing Data Centric Applications with Capacity Bursts Challenges Today “Capacity Bursting“ Elastic scale – database as a service Pay as you grow and shrink Easy to provision and manage Capacity Average Time Usage database Compute # of Hr’s Average Usage No hardware, no manual database administration required Promotions, events, ticket selling businesses are “bursts – bound” by nature Capacity constraints limit business agility High costs of entry into new business Difficult to roll out extra capacity quickly Idle capacity “off-bursts” is cost prohibitive
    • Data Centers

    • Windows Azure Roles  Your role class typically derives from RoleEntryPoint represents role  Do initialization in OnStart()  Do work in Run()  You call into RoleEnvironment to enumerate roles, endpoints, etc  You get called in response to changes in the number of instances in the service  Can force restart
    • Windows Azure Storage Building Blocks Each storage account can hold up to 100 TB
    • Windows Azure Blobs  Provide simple interface for storing named files along with metadata for the file
    • Windows Azure Blob features  REST based API  ouraccount.blob.core.windows.net/thecontainer/ myblob  PutBlob, GetBlob, DeleteBlob, CopyBlob, SnapshotBlob, LeaseBlob, etc  Block Blob for streaming + commit-based writes  Page Blob for random read/write  100 Tb per storage account
    • Windows Azure Drives  Page Blob formatted as a NTFS single volume Virtual Hard Drive (VHD)  NTFS APIs providing durable file storage on Page Blobs  Drives can be up to 1TB, up to 16 can be mounted  Can upload VHD via Page Blob then mount  Ease migration of existing Windows applications to Azure  Durability and survival of data on application failover or hardware failure
    • Windows Azure Tables  Structured storage via entities, containing sets of properties
    • Windows Azure Tables  Provides Massively Scalable Structured Storage  Billions of entities (rows) and TBs of data  Can utilise thousands of servers as it scales up  Triple replicated for durability  Familiar and easy to use REST based API  Each entity can have up to 255 properties  PartitionKey & RowKey as key and index  Timestamp for optimistic concurrency  No fixed schema for all other properties  Property is stored as a <name, typed value> pair
