Azure Services Platform
™

A set of building blocks for handling user data and application resources, and
extensible components to build rich social applications and consumer experiences
Live Framework
Extensible components to build rich consumer services
 Mesh Services – build applications that span across the web, devices, apps, and services
User – Mesh management and sharing resources across multiple users
o
Device – facilities for managing the collection of heterogeneous devices; relationship, status, security
o
Synchronization – data and metadata synchronization framework across applications, devices, and cloud
o
Application – facilities for managing the configuration, deployment, and versioning of applications
o
Identity Services – manage identities with associated services; delegated authentication

Directory Services – manage relationships between identities, data, devices, and apps

User-Data Storage Services – manage user-centric information; extensible data types

Communication and Presence Services – transport infrastructure for transient and persistent state

management between applications and devices
Search Services – facilities for building search capailities for web sites and applications

Geospatial Services – geocoding/reverse geocoding, routing, search, mapping data

Development Platform
Uniform way for programming Live Services from any platform, language, application or device
 Exposes RESTful programming model for live resources
 Protocol based – open standards usage: HTTP, XML, ATOM, RSS
 Resource Model: unified model across Live
 Symmetric client/cloud programming model
 CRUD/Query, triggers and SPROC based interaction model
 Libraries: Rich client libraries (.NET, Silverlight, JavaSript etc.)

Set of highly scalable, developer-oriented services that provide key building
blocks required by many cloud-based and cloud-aware applications
Service Bus
Exchange messages between loosely coupled, composite applications
 Connectivity to on-premises applications; secure, federated firewall-friendly messaging; simple,
connected pub-sub eventing; extension of WCF
 Federated namespace – shared, hierarchical, Internet-accessible URL
 Service registry – publish service endpoints, lightweight, hierarchical, RSS-based discovery
 Relay and connectivity – unicast/multicast datagram distribution, bidirectional sockets, request-
response messaging, pull-mode message delivery, Web service intermediary, WS-*/SOAP, REST
Access Control Service
Rules-driven application access control to users across organizations
 Security Token Service (STS) – User name/password, Windows CardSpace, X.509 certificate, 3rd-
party STS-issued SAML token, WS-Security, WS-Federation
 Each .NET Services solution has a private, isolated STS; backing identity infrastructure for all
services published within that solution’s Service Bus namespace
 Claims-based rules-driven authorization – configured via claim mappings
Workflow Service
Model and execute business logic and service interactions
 Reliable and scalable cloud runtime environment for user-defined declarative workflows
 Extends Windows Workflow Foundation (.NET 3.5) to the cloud
 Activities optimized for sending, receiving, and manipulating HTTP and Service Bus messages
 Deploy, manage and track running workflow instances using tools and APIs

Services

Highly scalable and Internet-facing distributed database services in the cloud for
storing structured and unstructured data, and processing relational queries
SQL Data Services
Internet-facing database built on SQL Server relational database
 Data storage – blobs, flexible, structured, birth to archival, multiple consistency levels
 Data Processing – filters, aggregates, user-defined logic, online-offline indexing
 Data Delivery – network proximity aware, locate closest static-content copies, spanning trees for
live-content, failure resiliency
Scalable, Flexible, Reliable, and Secure
High-availability database, scale as needed and without limits
 Data partitions limited to single node on cluster – efficient replication and load balancing
 Geo-replication and transactional consistency of data across multiple copies
 Geo-location configuration helps protect against latency and improve response time
 HTTPS/SSL support; built on SQL Server security infrastructure
Developer Agility
Standards-based interface and familiar language support
 Access runtimes through standards-based interfaces and Web services – SOAP and REST
 Perform CRUD operations with authorities, containers, and entities
 Relational queries via text-based queries, LINQ, typed data in XML wire format
 Simple filtering, retrieval of complete entities, full-text search, paging queries
 Flexible data model, no schema required

Cloud Storage (blob, table, queue)

Cloud services operating system that provides on-demand compute and storage
capabilities to host, scale, and manage applications
Compute Services
Scalable and reliable Web applications 64-bit hosting service in the cloud
 .NET 3.5 SP1, managed/native code, ASP.NET, IIS 7, SOAP/REST/XML, Ruby, Python, PHP
 Security supported by flexible Code Access Security policies
 Small runtime API supports logging and local scratch storage
Storage Services
Simple data storage for cloud-based applications
 Blobs & file streams, simple tables & caches, and queues; local and remote REST-based access
 Geo-distribution and geo-replication
 Authenticated access and triple replication
Management Services
Manage the applications, not infrastructure
 Advanced tracing & logging – monitor compute, storage, and bandwidth
 Dynamically upgrade applications without downtime
 Resource usage and performance insights; monitoring & metering
Development Tools
Model and execute business logic and service interactions
 Complete offline environment, including compute and storage services
 Visual Studio add-in enables local debugging (Eclipse soon)

Design Considerations
data process security management
latency stateless claims-based leverage
authorizaation automation
public / share- idempotent
able identity plan for average
isolation
federation load
reference data
loosely-coupled
end user aware of
primary key
asynchronous identities application
access
IPC lifecycles
not all data is
fault-tolerant rolling changes to
equal
(expect live services
failures)
handle dynamic
data schema and
configuration
changes

Potential Scenarios
Parallel and distributed processing
 Image processing and rendering
 Media content transcoding and publishing
 Finding extra-terrestrials
Voting systems
Share-able reference data
 Search indexes, catalogs
 Maps, profiles, blogs, files, documents, etc.
Composite services
Agent architectures
Multi-enterprise business applications
 Inter-organizational (B2B) business processes
 Extend enterprise SOA to other enterprises
