1.1. What is Red Hat JBoss Fuse Service Works?
リンクのコピーリンクがクリップボードにコピーされました!
Red Hat JBoss Fuse Service Works is a platform for developing enterprise application integration (EAI) and service-oriented architecture (SOA) solutions. It consists of a service component framework, business rules/complex event processing, life-cycle governance, runtime governance, and process automation. Red Hat JBoss Fuse Service Works is built on the same core as JBoss Fuse, and includes enterprise messaging, Apache Camel, and Apache CXF. Red Hat JBoss Fuse Service Works enables users to design, deploy, integrate, and orchestrate business services.
Red Hat JBoss Fuse Service Works can be used to integrate your major business systems into a cohesive infrastructure. Development is simplified with a transparent, lightweight service framework which uses Enterprise Integration Platform (EIP) technology. This allows developers to work with familiar technologies such as Apache Camel, BPEL, BPMN, or POJOs. To reduce the operational costs of production and maintenance, the platform utilizes an automatable, content-aware repository and service activity monitoring. These support the entire service life cycle.
1.2. Core Functionality
リンクのコピーリンクがクリップボードにコピーされました!
Red Hat JBoss Fuse Service Works provides the following core functionality:
- Enterprise Integration Pattern (EIP) Based Development
- The versatile EIP framework is implemented in routing and transformation processes for faster and more efficient integration solutions.
- High Performance Messaging
- A high performance messaging broker supports messaging patterns such as publish-subscribe, point-to-point, and store-forward, and multiple cross language clients.
- Service Development
- The web services framework exposes integration assets as services and calls external services, supporting all major web services standards. It also supports RESTful calls.
- Structured Service Development
- A lightweight service development framework provides full life-cycle support for developing, deploying, and managing service-based applications.
- Automatable Registry with Workflow
- Manage the life-cycle of services from design, development, and deployment by defining, exposing, and enforcing rules or policies.
- Business Transaction Monitoring
- Capture service activity information, define and collect metrics, and define alerts and SLAs.
1.3. System Integration

Integrating your major business systems into a cohesive infrastructure can be a challenge, especially when you have legacy applications. Red Hat JBoss Fuse Service Works provides a number of ways that enable you to integrate both new and legacy applications. Development is simplified with a transparent, lightweight service framework which uses the EIP technology. This allows developers to focus on higher order concepts while still working with familiar technologies such as Apache Camel, BPEL, BPMN, or POJOs. To reduce the operational costs of production and maintenance, the platform utilizes an automatable, content-aware repository and service activity monitoring. These support the entire service life cycle and development, QA, and production teams with runtime and design-time visibility, monitoring, and alerting.
1.4. Core and Components

Red Hat JBoss Fuse Service Works provides an environment for easily applying SOA concepts to integrated applications. A SwitchYard application consists of components such as composite services and composite references. These provide service definitions and accessibility.
Along with SwitchYard, Red Hat JBoss Fuse Service Works is made up of a number of components including a rules-based router (Apache Camel), a web service framework (Apache CXF), and a message broker (Apache ActiveMQ).

These components can be used in Red Hat JBoss Fuse Service Works to enable developers to build the required functionality using reliable and familiar tools. Some examples of how the components can be used are shown below:
- Bean Services with CDI
- SwitchYard leverages the power of Java EE6 and CDI to allow Java objects become services by adding an @Service annotation to your bean. Beans are automatically registered at runtime and references to other services can be injected as CDI beans using the @Inject annotation. Use CDI in your JSP and JSF applications to inject enterprise services into the web tier.
- Declarative Transformation
- With declarative transformation in SwitchYard, you can define the transformation and types to which it applies. SwitchYard automatically registers and executes the transformation. Choose from Smooks, Java, XSLT, JSON, and more.
- Decision Services with JBoss Rules
- Encapsulate business rules as decision services using the JBoss Rules component in SwitchYard. Each service has a well-defined contract with protocol binding details and marshaling details abstracted away by SwitchYard.
- Smooks
- This transformation engine can be used in conjunction with Red Hat JBoss Fuse Service Works to process messages.
- Business Process Execution Language (BPEL)
- You can use web services to orchestrate business rules using this language. It is included with Red Hat JBoss Fuse Service Works for the execution of business process instructions.
- JBoss Rules
- This is the rules engine that is packaged with Red Hat JBoss Fuse Service Works. It can infer data from the messages it receives to determine which actions need to be performed.
- Testing
- Comprehensive unit test support is provided to allow you to test services as you develop them.
