Service Bus Overview

Service Bus helps to provide secure connectivity between loosely-coupled services and applications, enabling them to navigate firewalls or network boundaries and to use a variety of communication patterns. Services that register on Service Bus can easily be discovered and accessed, across any network topology.

Use Service Bus to:

• Connect Windows Azure applications and SQL Azure databases with existing applications and databases
• Bridge on and off-premises applications
• Create composite applications

Service Bus Benefits

• Expose apps and services through firewalls, NAT gateways, and other problematic network boundaries
• Lower barriers to building composite applications by exposing endpoints easily, supporting multiple connection options and publish and subscribe for multicasting. 
• Lightweight developer friendly programming model that supports standard protocols and extends similar standard bindings for Windows® Communication Foundation programmers
• Helps blocks malicious traffic and shields your services from intrusions and denial-of-service attacks

Service Bus Features

• Services discovered through a stable, internet-accessible URL, irrespective of location
• One-way messaging between sender and listener supports unicast and multicast datagram distribution
• Full-duplex connection-oriented sessions between sender and listener support bi-directional communication
• Full-duplex, connection-oriented peer-to-peer sessions with network-boundary traversal create direct end-to-end connectivity through NAT
• Multiple publishers and multiple subscribers can simultaneously use the service’s topic management and event distribution system
• Support of REST and HTTP Access from non-.NET platforms
• Global hierarchical namespaces that are DNS- and transport- independent
• Anonymous access to services is supported only if you permit it

Access Control Overview

The Microsoft® Access Control helps you build federated authorization into your applications and services, without the complicated programming that is normally required to secure applications that extend beyond organizational boundaries. With its support for a simple declarative model of rules and claims, Access Control rules can easily and flexibly be configured to cover a variety of security needs and different identity-management infrastructures.

Use Access Control to:

• Create user accounts that federate a customer's existing identity management system that uses Active Directory® service, other directory systems, or any standards-based infrastructure
• Exercise complete, customizable control over the level of access that each user and group has within your application.
• Apply the same level of security and control to Service Bus connections

Access Control Benefits

• Federated identity and access control through rule based authorization enables applications to respond as if the user accounts were managed locally
• Flexible standards-based service that supports multiple credentials and relying parties
• Lightweight developer-friendly programming model based on the Microsoft .NET Framework and Windows Communication Foundation
