O porquê da nuvem?

O que é a nuvem?

A Computação em Nuvem é um estilo de computação em que recursos de TI altamente escaláveis são fornecidos como um serviço usando tecnologias de Internet a vários clientes externos

Características da nuvem?Escalabilidade elásticaCapacidade virtualmente infinitaPaga baseado no consumoPelo tempo que quiser Alta confiabilidadePresença Global

SLA mensal 99.95%

Windows Azure Data Storage Concepts

Account Table Entities

Queue Messages

Container Blobs

https://<account>.blob.core.windows.net/<container>

https://<account>.table.core.windows.net/<table>

https://<account>.queue.core.windows.net/<queue>

Windows Azure BlobsUpload/Download BlobsProvides continuation for large uploadsProvides range readsStrong Consistency and Optimistic Concurrency

Conditional operations – If-Match, If-Not-Modified-Since, etc.

A highly scalable and durable file system in the cloud

Store files as blobs and associate metadata with itBlobs can be up to 200 GB in size

Snapshot BlobCreate versions/backup of your blobs

Lease BlobExclusive write lease

Efficient Resume for browsers and streaming media players require:

Windows Azure Queues

Provides reliable message delivery

Programming semantics – Ensures that a message can be processed at least once Put message into the queue

Get message makes the message invisible in queue for a specified invisibility timeout

Delete message once done processing to remove message from queue

If worker crashes, message becomes visible for another worker to process

Queues DemoDemo

Windows Azure TablesScalable Structured StorageStore Tables with billions of entities and TBs of data

Provides flexible schema (NoSQL)

Data Model

A table is a set of entities (rows)

An entity is a set of properties (columns)

Familiar and Easy to use APIOData Protocol

WCF Data Services - .NET classes and LINQ

Insert entityUpdate entity

Merge Replace

Query Projection ($select)
