The document outlines an agenda for a Windows Azure camp held on April 10, 2011, covering key aspects of cloud computing and Windows Azure services. It details the components of Windows Azure, including IaaS, PaaS, and SaaS, as well as features like storage services and SQL Azure. The document emphasizes the benefits of cloud computing, such as reduced maintenance costs and scalability, while explaining various roles and functionalities within the Azure environment.

19. Windows Azure Compute

20. ComputeA Windows Azure compute service is built from one or more roles. In Windows Azure, a service may run one or more instances of each role type. A service could also be composed of one of more instances of multiple role types. Windows Azure supports the following three types of roles:Web role is customized for web application programming and supported by IIS 7.Worker role is used for generalized development, and may perform background processing for a web role.Virtual Machine (VM) role runs an image (a VHD) of a Windows Server 2008 R2 virtual machine. This VHD is created using an on-premises Windows Server machine, then uploaded to Windows Azure.

27. Windows Azure Storage

28. Azure StorageNeed persistent and durable storage in the cloud? Windows Azure is a perfect fit. Windows Azure gives you four core storage services that are secure, scalable and easy to access.Binary Large Object Service(Blobs) Table Service ( Tables)Queue Service ( Queues)Windows Azure DriveQueueTablesBlobs

29. Azure Storage - BLOBSBlobs are one of the most credible feature with AzureProvide a simple interface for storing named files along with metadata for the fileIt’s very much reliable with Large size of fileMain Concept : Account, Container, Blob , Block

30. Azure Storage – BLOBS – Key ConceptsBlobContainerAccountBlockIMG001.JPGPicturesIMG002.JPGAccountBlock AMoviesMOV1.AVIBlock BBlock C

31. Azure Storage – BLOBS – How it works ?Movie.aviMovie.aviMovie.aviIdentify the file to be uploaded (Movie.avi).Identify / split the blocks for the file.Upload every block in any order you want to.Commit the block to a blob.Block 1Block 2Block 3Block 4Block 5

32. Azure Storage – BLOBS – Must KnowKey Points Files has to split to have blocks when it crosses 64 MB. Every block can be a maximum of 4 MB size. The maximum size of the blob / file can be 200 GB or 50,000 blocks. The blocks uploaded is not committed unless the final API call "PutBlockList" is called. Block blobs though offer a very good and effective way of working with bigger files, it lacks on certain places.The maximum size of the file can be no larger than 200GB. It needs at least two API calls to write a blob when uploaded as blocks. [PutBlockto upload a block with block id and PutBlockListto commit all the changes]. Any uploading cannot be committed immediately unless the final call "PutBlockList" is made. Reading a byte range other than the block split cannot be done.

33. Azure Storage – Page BLOBSThe maximum size of a page blob file would be 1 TB. The least page size is 512 bytes and can accommodate any data in multiples of 512 bytes up to 4 MB into a page. As soon as a data is uploaded, it is written into the cloud / disk. All the data / pages inside the page blobs are indexed to allow faster read / write. Windows Azure Drive (TBD) is supported. A page can be considered as a individual file and read / write operation can be performed on it.

34. Azure Storage - Tablesprovide structured storage. A table is a set of entities, which contain a set of propertiesThere is no limitation on the number of table / collection and rows. Every entities can have up to 255 properties. Every entity should have a property defining the row key "RowKey" and partition key "PartitionKey". Row key is the unique identifier of the row and partition key is generally any property which would be better for maintaining partition. (e.g., DepartmentId in an entity of Employee). The limitation of not being an RDBMS is easily and effectively overcome by the support of LINQ on the tables. A LINQ query can therefore be written and executed against the tables. Every table is mirrored thrice in Azure and the reliability and availability is maintained automatically. Every table has a partition keyIt is the first property (column) of your tableAll entities in a table with the same partition key value live in the same partition Need to choose partitioning scheme to make data access scalable

36. Azure Storage - Queueprovide reliable storage and delivery of messages for an applicationKey Concept : Account, Storage, MessageA message in queue has a limitation of 8 KB in size. A Queue has no limitation on the number of messages it can contain. Messages cannot choose their destinations individually but they follow the path or receiver of the queue. Message when consumed by acquiring token which expires by time i.e., once a message is got it will be locked / hidden from any other process unless the time expires or the message is deleted; if the time expires, the message will be marked as new and will be provided to the next consumer waiting. A detailed process is explained in the animation shown below. Messages can be even got without a time expiry and immediately marked as processed.
