Windows Azure Overview Simon Thurman Azure Incubation Email: simont Twitter: @simonthurman
The Windows Azure Platform Windows Azure is an internet-scale cloud services platform hosted in Microsoft data centers around the world, proving a simple, reliable and powerful platform for the creation of web applications and services.
Service Management is performed by the Fabric Controller, which controls all the resources within the data center. The Fabric Controller deploys your service and monitors the overall health of the fabric. Security and Control State-of-the-art physical security processes combined with strictly controlled OS access model. Data is replicated in multiple fault domains in location selected by the customer. Virtualized Computation provides massive application scalability. Customers can build a combination of web and worker roles. Those roles can be replicated as needed to scale the applications and computational processing power. Storage Services allow customers to scale to store large amounts of data – in any format – for any length of time, only paying for what they use or store. State-of-the-art data centers located around the world. Host your applications and data securely, accessible from everywhere you allow. Windows Azure Automates the Management of Your IT Resources
Compute Services in Windows Azure GOAL: Massive Scalability Two role types: Web Role & Worker Role Windows Azure applications are built with web roles, worker roles, or a combination of both deployed to a number of instances. Scale out – not up – by replicating worker instances as needed. Allow applications to scale user and compute processing independently. Each instance runs on its own VM (virtual machine), replicated as needed
Windows Azure storage is an application managed by the Fabric Controller
Windows Azure applications can use native storage, MySQL within a VM, or SQL Azure
Application state is kept in storage services, so worker roles can replicate as needed
Blobs can be stored in global Windows Azure Content Delivery Network (CDN)
Storage Services in Windows Azure GOAL: Scalable, durable utility-based storage
Blobs, Tables, Queues and Drives BLOBS: Provide a simple interface for storing named files along with metadata for the file. DRIVES: A durable NTFS file system volume, sharable across instances. QUEUES: Provide reliable storage and delivery of messages for an application. TABLES: Provide structured storage. A table is a set of entities which contain a set of properties.
