This document provides an overview of the Microsoft Windows Azure platform, including its data center infrastructure, categories of services, and key projects. Some of the main points covered include: - Windows Azure uses globally distributed data centers housed in shipping containers to maximize server density and efficiency. - It provides various compute, storage, data, connectivity, security, and application services through a generalized cloud application model. - Key projects expand on services for identity/access management, caching, service hosting, information delivery, and more.

- 14. Windows Azure Diagnostics Compute > Configurable trace, performance counter, Windows event log, IIS log & file buffering • Local data buffering quota management • Query & modify from the cloud and from the desktop per role instance • Transfer to storage scheduled & on-demand • Filter by data type, verbosity & time range
- 15. Windows Azure Storage > Rich data abstractions – tables, blobs, queues, drives, CDN • Capacity (100TB), throughput (100MB/sec), transactions (1K req/sec) > High accessibility • Supports geo-location • Language & platform agnostic REST APIs • URL: http://<account>.<store>.core.windows.net • Client libraries for .NET, Java, PHP, etc. > High durability – data is replicated 3 times within a cluster, and (Feb 2010) across datacenters > High scalability – data is automatically partitioned and load balanced across servers StorageStorage
- 16. Windows Azure Table Storage Table Storage > Designed for structured data, not relational data > Data definition is part of the application • A Table is a set of Entities (records) • An Entity is a set of Properties (fields) > No fixed schema • Each property is stored as a <name, typed value> pair • Two entities within the same table can have different properties • No schema is enforced
- 17. Windows Azure Blob Storage Blob Storage > Storage for large, named files plus their metadata > Block Blob • Targeted at streaming workloads • Each blob consists of a sequence of blocks • Each block is identified by a Block ID • Size limit 200GB per blob > Page Blob • Targeted at random read/write workloads • Each blob consists of an array of pages • Each page is identified by its offset from the start of the blob • Size limit 1TB per blob
- 18. Windows Azure Queue Queue > Performance efficient, highly available and provide reliable message delivery > Asynchronous work dispatch • Inter-role communication • Polling based model; best-effort FIFO data structure > Queue operations • Create Queue • Delete Queue • List Queues • Get/Set Queue Metadata > Message operations • Add Message • Get Message(s) • Peek Message(s) • Delete Message
- 19. Windows Azure Drive Drive > Provides a durable NTFS volume for Windows Azure applications to use • Use existing NTFS APIs to access a durable drive • Durability and survival of data on application failover • Enables migrating existing NTFS applications to the cloud • Drives can be up to 1TB; a VM can dynamically mount up to 8 drives > A Windows Azure Drive is a Page Blob • Example, mount Page Blob as X: • http://<account>.blob.core.windows.net/<container>/<blob> • All writes to drive are made durable to the Page Blob • Drive made durable through standard Page Blob replication
- 20. Windows Azure Content Delivery Network > Provides high-bandwidth global blob content delivery • 18 locations globally (US, Europe, Asia, Australia and South America), and growing > Blob service URL vs. CDN URL • Blob URL: http://<account>.blob.core.windows.net/ • CDN URL: http://<guid>.vo.msecnd.net/ • Support for custom domain names > Access details • Blobs are cached in CDN until the TTL passes • Use per-blob HTTP Cache-Control policy for TTL (new) • CDN provides only anonymous HTTP access Content Delivery Network
