  • From Directions on Microsoft: Chicago class. Named for the facility under way in Northlake, a suburb of Chicago, this type of data center is optimized for massive scale. Instead of using racks of servers, this facility is designed to accept shipping containers, each filled with approximately 2,500 servers, designed to a Microsoft specification and known internally as "Cblox." (For a photo of the interior of such a container, see "Inside a Data Center Container".) The building is designed like a parking garage, with spaces for semitrailers carrying containers. A single connector on the outside of the shipping container links its computers to a "spine" that contains connections for power, network, and cooling. This allows a Chicago-class facility to have hundreds of thousands of servers, with one employee on site for approximately every 30,000 servers. When a certain percentage of the servers in a particular container are offline or obsolete, Microsoft will decommission the entire container of 2,500 servers—a process that could take months in a Quincy-class facility will take approximately one hour in a Chicago-class facility. This ease of replacement will also allow Microsoft to improve energy efficiency over time, as new container designs will include more servers and more efficient cooling systems.

    18. 18. Windows Azure Storage Massive scale and low cost Durable, available, scalable and secure Redundant copies, commodity hardware, layered architecture Blobs: Simple interface for storing named files along with metadata for the file Tables: Structured storage. A set of entities, which contain a set of properties. Partitonable Queues: Reliable storage and delivery of messages for an application
    19. 19. Windows Azure Storage: Blobs Store Large Objects (up to 50 GB each) Account/Container/Blob/Block naming Standard REST Put/Get Interface PutBlob(BlobName, stream, size) Overwrites the existing blob by that name GetBlob(BlobName, starting offset, length) DeleteBlob(BlobName) Associate Metadata with Blob Metadata is <name, typed value> pairs Set/Get with or separate from blob data bits Up to 8KB per blob
    20. 20. Streaming a Blob via Blocks Uploading a Large Blob blobName = “MyMovie”; Benefit: • Efficient continuation and retry • Parallel and out of order upload of blocks PutBlock(blobName, blockId1, block1Bits); PutBlock(blobName, blockId2, block2Bits); Block Id N Block Id 3 Block Id 2 Block Id 1 10 GB Movie ………… PutBlock(blobName, blockIdN, blockNBits); PutBlockList(blobName, blockId1,…,blockIdN); MyMovie Windows Azure Storage 22
    21. 21. Windows Azure Storage: Tables
    22. 22. Windows Azure Storage: Tables Structured storage in the form of Tables A Table is a set of entities (rows) An Entity is a set of properties (columns) Namespace Account Name – Table Name Entity (PartitionKey, RowKey) Table Name You give a unique name to each Table, which is scoped by Account An account can create many tables Focus is to provide Scalable Structured Storage via Tables Not a relational database (e.g., no foreign keys, no joins, etc)
    23. 23. Windows Azure Storage: Tables Your table can grow to be billions of entities (rows) and TBs of data The table may need to be spread across thousands of servers to handle traffic to that table Partitioning is how we spread the table out The Table’s entities are broken into partitions
    24. 24. Scaling Tables through Partitions Partition Key Document Name Row Key Version Column 3 Modification Time Column 4 State …… …. Column N Description Examples Doc V2.0 8/2/2007 Current …… …. Committed version Partition 1 Examples Doc V2.0.1 9/28/2007 Working Alice’s working version FAQ Doc V1.0 5/2/2007 Current Current committed version FAQ Doc V1.0.1 7/6/2007 Working Alice’s working version FAQ Doc V1.0.2 8/1/2007 Working Sally’s working version FAQ Doc V1.0.3 9/6/2007 Working Bob’s working version Partition 2 Table’s entities are broken up into Partitions Partition: set of entities with same partition key value PartitionKey – unique ID for the partition within the Table RowKey – unique ID for the row within the partition All Queries are sorted by Partition Key and then by Row Key Each partition can be served by different nodes 26
    25. 25. Why Partition? Entity Locality Entities in the same partition will be stored together for efficient querying and cache locality when accessing Table Throughput Table Storage automatically performs partition load balancing based upon the partition key Scale to meet the traffic needs of your application 27
    26. 26. Windows Azure: Queues Provides reliable queued message delivery Simple, asynchronous work dispatch via queues The programming semantics ensure that a message is retrieved at least once Queue access provided via REST Account can contain Queues Queue contains Messages URL: http://<Account>.queue.core.windows.net/<QueueName> Queues contain Messages Message Size <= 8 KB Messages can contain references to blob/table storage 28

    36. 36. .NET Services: Access Control Svc Challenge Ensuring secure transactions for systems in disparate security domains is crucial but difficult to implement COMPANY C COMPANY A ADFS COMPANY B Secure Provides hosted identity and access services for organizations while allowing them to fully control it Federated & Flexible Next-generation AD access and federation services for organization and third-party applications Standards Based Claims based access control using secure tokens Based on standards such as WS-Trust, REST and SOAP
    37. 37. .NET Services: Service Bus Challenge Applications built in the cloud will need to span systems to talk to other third party apps or applications that are on premise APPLICATION D INTERNET SERVICE BUS APPLICATION A APPLICATION B APPLICATION C Federated Applications can connect securely across firewalls and org boundaries in a loosely coupled, federated manner Powerful Request - Response, and publish subscribe with multiple senders and receivers on a single rendezvous point Simple low footprint download built using standards such as HTTP, RSS, SOAP
    38. 38. Service Bus (WCF Relay Bindings) Identity Service Trust Authenticate Connectivity Service 3 Connect Open 4 2 1 Authenticate 5 Relayed Connection Client 6 Direct Connection (optional) Service 41
    39. 39. .NET Services: Workflow Challenge As activities are offloaded to the cloud, how do you do long running multi step activities driven by events Application C Visual Studio XAML Application B Application A Agility Enables you to create workflows without worrying about deployments Simplicity Uses similar programming model as on-premises workflows Federated Enables cross-organization and cross-trust domain workflows
    40. 40. Workflow (Update) Windows Workflow in the cloud! XOML only Restricted list of allowed activities Basic “process orchestration” between parties HttpReceive HttpSend ServiceBusSend XPathRead XPathUpdate Basic copy/paste deployment Can also be done via an API 43
