  5. What is the cloud? An approach to computing that’s about internet scale and connecting to a variety of devices and endpoints

  6. Why Cloud? • Customer Requirements : • Efficency, Reliability • Scalability , Agility • Reduce IT Costs • IT Consultants • Don’t must be IT warriors • Can delegate IT Problems

  7. “Growing Fast“ “On and Off “ Inactivity Period Compute Compute Average Usage Usage Average Cloud Computing Patterns Time Time • Successful services needs to grow/scale • On & off workloads (e.g. batch job) “Unpredictable Bursting“ “Predictable Bursting“ Compute Compute Average Usage Average Usage Time Time • Unexpected/unplanned peak in demand • Services with micro seasonality trends

  8. Cloud Services Infrastructure-as-a-Service “PaaS” “IaaS” “SaaS” Platform-as-a-Service Software-as-a-Service consume build host

  9. Caso Cloud: Il Censimento • 500 000 connessione in un solo giorno • Carico di workload inaspettato • In tilt dopo poche ore • dal lancio • Raddoppiata l’infrastruttura IT in una sola Notte • Infrastuttura Cloud : Telecom Italia

  10. Scalable compute and storage • Automated service management • Familiar tools, technologies, languages Windows Azure Platform • Relational storage for the cloud • Consistent development model • Automated database management • Connect existing apps to the cloud • Connect through network boundaries • Easily control authorization to apps

  11. Windows Azure Platform : Layers Middleware Services AppFabric Access Control AppFabric Service Bus AppFabric Caching SQL Azure Windows Azure Storage Windows Azure CDN Data Services “Red Dog” Front End (RDFE) Compute Services Windows Azure Networking Fabric Controller

  20. Azure Role : Scale Application Archetype

  21. Azure Scale Applications: Layers Intelligent Network : Load Balancer Stateless Web Application : Web Role Stateless ‘Worker’ Machines : Worker Role Async Work Data /State Tier Queues Key/ValueDatastores Partitioned RDBMS Shared Filesystem

  22. Azure Scale Applications: Roles The Internet via HTTP/TCP Tables LB LB LB Storage Queues Web Site (ASPX, ASMX, WCF) Worker Service Web Site (ASPX, ASMX, WCF) Worker Service Web Role IIS as Host Worker Role Managed Interface Call Blobs Windows Azure Data Center

  23. AzureRole: Application Box Role is an application container, that run inside Azure VM, through it we can provide Web / Service / Standalone Applications and also offers an interface to manage it Events Methods Status Role Interface Role Lifetime Busy OnStart StatusCheck Requests Routed Fabric Calls StatusCheck Ready Run Busy OnStop StatusCheck Stopping

  24. Services,Roles and Instances A Service is a packaged application for Azure, composed by one or more role 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

  25. 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 • E.g. Run a .NET SMTP server or WCF Service 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

  26. Web Role All features of a worker role + IIS 7 or 7.5 MVC 3 , ASP.NET 3.5 SP1 or 4.0 – 64bit Hosts • Webforms or MVC • FastCGI applications (e.g. PHP) • Multiple Websites Http(s) Web/Worker Hybrid • Can optionally implement RoleEntryPoint

  27. Service Definition Describes the shape of your Windows Azure Service Defines Roles Ports, Certificates Configuration Startup Tasks IIS Configuration

  28. Service Configuration Supplies Runtime Values, can be updated any time through Portal or API Scale Config Settings Certificates to use, VHD etc.

  29. VM Size in Windows Azure Windows Azure • Supports Various VM Sizes • Size set on Role in Service Definition • Service can have multiple roles • Balance of Performance per node vs. High Availability from multiple nodes • Set in Service Model definition All instances of role will be of equal size

  30. Windows Azure Platform Portal Web Access to : https://windows.azure.com Supports multiple service administrators (co-admins) Enable and connect to Windows Azure instances using Remote Desktop Built on the Windows Azure Service Management APIs

  31. Demo Hello World by Windows Azure

  32. Windows Azure Storage

  33. Windows Azure Storage Storage in the Cloud • Scalable, durable, and available • Anywhere at anytime access • Only pay for what the service uses Exposed via RESTful Web Services • Use from anywhere on the internet • User specified globally unique account name • Can call these from any HTTP client (Flash, Silverlight ) Various storage abstractions • Tables, Blobs, Queues, Drives 100TBper account, have two independent 512 bit shared secret keys

  34. Blob Storage

  35. Account Container • Blob • Pages/ • Blocks http://<account>.blob.core.windows.net/<container>/<blobname> Blob Storage Concepts • PIC01.JPG • Block/Page • images • VID1.AVI • PIC02.JPG • contoso • Block/Page • videos

  36. Blob Details Main Web Service Operations • PutBlob,GetBlob • DeleteBlob,CopyBlob • SnapshotBlob ,LeaseBlob Associate Metadata with Blob • Standard HTTP metadata/headers (Cache-Control, Content-Encoding, Content-Type, etc) • Metadata is <name, value> pairs, up to 8KB per blob • Either as part of PutBlob or independently Blob always accessed by name • Can include ‘/‘ or other delimeter in name e.g. /<container>/myblobs/blob.jpg

  37. Blob Containers Multiple Containers per Account • Special $root container Blob Container • A container holds a set of blobs • Set access policies at the container level • Associate Metadata with Container • List the blobs in a container • Including Blob Metadata and MD5 • NO search/query. i.e. no WHERE MetadataValue = ? Blobs Throughput • Effectively in Partition of 1 • Target of 60MB/s per Blob

  38. Table Storage

  39. http://<account>.table.core.windows.net/<tablename> Account Table Entity Table Storage Concepts Name =… Email = … customers Name =… EMailAdd= … contoso Photo ID =… Date =… photos Photo ID =… Date =…

  40. Table Details It’s not an RDBMSsystem but it’ s a container where we can serialize a collection of objects Table Operations : • Create, Query, Delete • Tables can have metadata Entities Operations : • Insert,Delete • Update • Merge – Partial update • Replace – Update entire entity • Query • Entity Group Transactions • Multiple CUD Operations in a single atomic transaction

  41. Entity Properties Entity can have up to 255 properties ( members of class ) • Up to 1MB per entity Mandatory Properties for every entity • PartitionKey & RowKey (only indexed properties) • Uniquely identifies an entity • Defines the sort order • Timestamp • Optimistic Concurrency. Exposed as an HTTP ETag No fixed schema for other properties • No schema stored for a table • Properties can be the standard types: • String, binary, bool, DateTime, GUID, int, int64, and double

  42. http://<account>.table.core.windows.net/<tablename> http://antimo.table.core.windows.net/Accounts Querying ?$filter=Last eq ‘Akers’

  43. Queue Storage

  44. Queue Storage Concepts http://<account>.queue.core.windows.net/<queuename> Message Queue Account customer ID order ID http://… order processing adventureworks customer ID order ID http://…

  45. Loosely Coupled Workflow with Queue Enables workflow between roles • Load work in a queue • Producer can forget about message once it is in queue • Many workers consume the queue • For extreme throughput use multiple queues or multiple work items per message Input Queue (Work Items) Queue Worker Role Web Role Worker Role Web Role Worker Role Web Role Worker Role

  46. Queue Details Simple asynchronous dispatch queue • No limit to queue length subject to storage limit • 8kb per message • ListQueues- List queues in account Queue operations • CreateQueue ,DeleteQueue • Get/Set Metadata • Clear Messages Message operations • PutMessage– Reads message and hides for time period • GetMessages – Reads one or more messages and hides them • PeekMessages – Reads one or more messages w/o hiding them • DeleteMessage – Permanently deletes messages from queue

  47. SQL AZURE Database

  48. Extending SQL Server to the Cloud SQL Azure Reporting Database Data Sync

  49. SQL Azure Database Familiar SQL Server relational database model delivered as a service • Support for existing APIs & tools • Built for the cloud with high availability & fault tolerance • Easily provision and manage databases across multiple datacenters SQL Azure provides logical server • Gateway server that understands TDS protocol • Looks like SQL Server to TDS Client • Actual data stored on multiple backend data nodes Logical optimizations supported • Indexes, Query plans etc.. Physical optimizations not supported • File Groups, Partitions etc… Transparently manages physical storage

  50. SQL Azure SQL Azure Use & Deployment : Web Portal (API) DB Script SQL Server Managment SQL Azure TDS Custom Tool
