Access Control Moving PartsAccess Control Moving Parts
• Portal– A UI for creating and managing
collections of access control rules• Client API
– Provides a programmatic way to manage collections of access control rules
• Service (STS)– A hosted service that issues tokens– Developers interact with the
service via the “Geneva” Framework

• Data services tier of the Azure Services Platform• Built on SQL Server foundation• Broad data platform capabilities as a service
– Friction-free provisioning, scaling– Significant investments in scale, HA, lights-out
operation and TCO

• It is an operating system for the cloud• It is designed for utility computing• It has four primary features:
– Service management– Compute– Storage– Developer experience
What Is What Is Windows AzureWindows Azure??

• The same facilities that a desktop OS provides, but on a set of connected servers:– Abstract execution environment– Shared file system– Resource allocation– Programming environments
• Utility computing– 24/7 operation– Pay for what you use– Simpler, transparent administration

• The Windows Azure provides core technologies for building rich services on top of unreliable but scalable hardware (i.e., a cloud operating system)– Supports building applications that scale– Programming tools and interfaces are
designed to be familiar to traditional desktop programmer
• Introduce new concepts that are similar to existing ones at a different abstraction level

• Types of roles and static role configuration• Set of configuration settings for a role• Contract with the environment code runs
• Service configurations– Defines values for properties that can be dynamically updated for a running deployment
• Values of a configuration parameter• Number of running instances

• Every role has access to APIs for common functionality needed for services– Read configuration setting values– Write messages to set
of standard logging streams• “Printf” sitting on top of a lot of plumbing
so logs are downloadable and archived easily• Critical messages generate live alerts
– Get access to unreliable local storage for caching
• Defines interface for worker role

• Blobs – provide a simple interface for storing named files along with metadata for the file
• Tables – provide structured storage. A table is a set of entities, which contain a set of properties
• Queues – provide reliable storage and delivery of messages for an application
