Blob Storage


Windows Azure 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

Windows Azure 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

“Geneva”> Next generation identity and access

management platform

• Claims-based access and single sign-on for on-premise and cloud-based applications in the enterprise, across organizations, and on the Web

> “Geneva Framework“ (Windows Identity Foundation)

• Provides .NET development tools, which includes pre-built, user-access logic that externalizes authentication from applications. It helps developers build claims-aware .NET applications, plus build custom security token services (STS)

> “Geneva Server“

• An STS for IT that issues and transforms claims and other tokens, manages user access and enables federation and access management for simplified single sign-on
