    Windows azure (by me) Windows azure (by me) Presentation Transcript

    • Windows Azure Tour
    • How did cloud computing evolve at first ?
    • Types
      Public – Available On self Service Basis
      Hybrid – Many into one
      Private – For Proprietary software's
    • Problems which lead to the innovation
      Piracy
      Software Cost
      Hardware Cost
      Man Power
      Security Issues
      Support for different Hardwares
    • Who are the Major players involved in developing a cloud OS ?
    • Agenda
      What is Windows Azure?
      Develop Your Application
      Deploy To Staging and Production
      Some Stuff To Think About
    • The Azure Platform
    • The Azure Platform
    • The “cloud” in Cloud Services?
      Think data-center somewhere on the internet
      Allows you to run your app
      Allows you to read and write data
    • Why Azure?
      “I’ve got my awesome data-center so…”
      No more worrying about…
      Buying, configuring, maintaining hardware
      Buying, configuring, maintaining the operating system
      Network infrastructure
      Routers, Switches, Load Balancers
      Your data-center’s power and internet connections
      Failovers
      Worry less about…
      App deployment
      Capacity planning
      Focus on writing your app
    • Have a look at Data Center of Azure at the initial stage of the project
    • Simple Scale Out
      Changes in traffic
      Need more servers?
      Need fewer servers?
    • Azure: The Developer View
      Write it in Visual Studio
      New project types
      Debug your code
      .NET, ASP.NET, WCF, IIS7, LINQ
      Azure Storage
      Database in the cloud
      (with a few caveats)
      Desktop development versions of
      Azure Fabric
      Azure Storage
    • Debugging In The Cloud
      We can debug a service in Visual Studio
      How do you debug a service that has been deployed?
      Answer: you don’t
      Logging is the answer
      RoleManager.WriteToLog(eventLogName, message)
      Event log name values: Error, Information, Warning, Debug, Critical
    • Azure Storage
    • Azure Storage
      Simple database in the cloud
      Tables
      “structured storage”
      Blobs
      Queues
      You don’t worry about replication
      Scales like nobody’s business
      Development version
      DevelopmentStorage.exe
      Uses SQL Server Express
    • Table Storage
      Every row has RowKey & Partition Key
      RowKey = primary key
      PartitionKey
      Helps you tell Azure how to scale your data
      You have to think about how you’ll be querying
      By State? By Hour? Other?
    • PartitionKey
      Your partitions could be on different servers
      Best practice: If you know your PartitionKey, add it to the WHERE clause
      No PartitionKey in the WHERE  insane table scans
      Recommendation: More partitions is (probably) better
      Think hard about your partition key in the beginning
      Else, roll your own re-partitioning
    • Column Data Types
      Partition key and Row key
      String (up to 64KB)
      Other properties
      String (up to 64KB)
      Binary (up to 64KB)
      Bool
      DateTime
      GUID
      Int
      Int64
      Double
    • More Than Just ASPX
    • Utility Compute without a UI
      Azure uses the concept of “Roles”
      There are two types of roles:
      Web role
      Worker role
    • Web & Worker
    • Worker Role and a Queue
      In a web role, create an ASP.NET page
      Creates a queue
      Writes to a queue
      Gets queue depth
      Worker Role
      Reads the queue
      “Processes” the message
    • How will the interface look like ?
    • Deployment
    • Deploy To The Cloud
      Change the storage config to use production servers
    • Miscellaneous
    • Things to think about
      No foreign keys
      No triggers
      No stored procedures
      In Table storage, strings can only be 64k
      You’ll need to use a mix of Blob and Tables
      Think hard about what config values you put in web.config/app.config vs ServiceConfiguration.cscfg
    • SaaS – Software as Service
      Take a look at this !
    • Final year projects
      Current market ?
      Landing a job in Microsoft ?
      Where to find the learning resources ?
