Enterprise Integration Patterns
What Are Enterprise Integration Patterns?
Enterprise Integration Patterns is a book by Gregor Hohpeand Bobby Woolf and describes 65 design patterns for the use of enterprise application integration and message-oriented middleware in the form of a pattern language.
Enterprise Integration Patterns
This patterns are organized into the following categories:
• Integration Styles• Messaging Systems• Messaging Channels• Message Construction• Message Routing• Message Transformation• Messaging Endpoints• System Management

• Apache ActiveMQ (Messaging)• Apache CXF (Web Services/REST)• Apache Karaf (OSGI)• Apache Camel (Routing, EIP)• SwitchYard (SCA*)• Fuse Fabric (Clustering Management)
* Service Component Architecture (SCA) is a set of specifications which describe a model for building applications
and systems using a Service-Oriented Architecture (SOA)
Apache - ActiveMQ
Apache - ActiveMQ
Apache ActiveMQ ™ is the most popular and powerful open source messaging andIntegration Patterns server.
Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features
Language ClientsJMS, ActionScript 3, Ajax, C, C++, C# and .Net, Delphi, Erlang, Flash/ActionScript, Haskell, JavaScript - Ajax or WebSocketsPerl, PHP, Pike, Python, Ruby and Rails support via ActiveMessaging, Smalltalk, WebSockets
Protocols SupportedOpenWire, REST, Stomp, WS Notification, XMPP, AMQPand more
Apache - CXF
Apache CXF is an open source services framework.
CXF helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS.
These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI.
Apache - Karaf
Apache Karaf is a small OSGI based runtime which provides a
lightweight container onto which various components and
applications can be deployed.
features supported by the Karaf:
Dynamic configurationLogging SystemProvisioningNative OS integrationExtensible Shell consoleRemote accessSecurity framework based on JAASManaging instances
Based on Apache Felix Framework
Apache Camel
Apache - Camel
Apache Camel is a versatile open-source integration framework based on known Enterprise Integration Patterns.
Camel empowers you to define routing and mediation rules in a variety of domain-specific languages, including a Java-based Fluent API, Spring or Blueprint XML Configuration files, and a Scala DSL. This means you get smart completion of routing rules in your IDE, whether in a Java, Scala or XML editor.
Uses URIs to work directly with any kind of Transport or messaging model such as HTTP, ActiveMQ, JMS, JBI, SCA, MINA or CXF, as well as pluggable Components and Data Format options.
Apache Camel lets you work with the same API regardless which kind of Transport is used.

SwitchYard is a component-baseddevelopment framework focused on building structured, maintainable services and applications using the concepts and best practices of SOA.
A uniform application model augments Apache Camel, joining Java EE, BPM, rules, orchestration, and routing into a cohesive development model and runtime.

Fuse Fabric
Fuse Fabric technology enable distributed
management of large clusters of ESBs.
Fuse has a Management Console from which you can manage the installation of your software across a cluster.

• A combination of modeling, automation, execution, control, measurement and optimization of business activity flows.
• Modeling - Identify, define, and make a representation of the complete process
• Automation - The work that is done to assure the smooth execution of the process instances
• Execution - Instances of a process are performed
• Control, Measurement - Making sure that the process follows the designed course and determine how well the process is working
• Optimization - discipline of BPM is an ongoing activity that builds over time to steadily improve the measures of the process.
