Introduction: Service integration

Explore the key concepts pertaining to service integration. A service integration bus is a form of managed communication that supports service integration through synchronous and asynchronous messaging. A bus consists of interconnecting messaging engines that manage bus resources. The members of a service integration bus are the application servers and clusters on which the messaging engines are defined.

Learning about service integration buses
A service integration bus is a group of one or more application servers or server clusters in an application server cell that cooperate to provide asynchronous messaging services.
Planning issues for bus topologies
To plan a bus topology, you must consider issues such as number of buses in the topology, distribution of messaging engines and bus destinations, and naming conventions for service integration bus resources.
Learning about messaging engines
Messaging engines are an important component of service integration technologies because they allow applications to communicate with the bus, and process messages.
Learning about data stores
A data store is a message store that uses a relational database. A messaging engine uses a data store to store operating information in the database, as well as to preserve essential objects that the messaging engine needs for recovery in the event of a failure.
Learning about bus destinations
Service integration has the following types of bus destinations: queue, topic space, foreign, and alias. Each has a different purpose.
Learning about mediations
Use mediations to influence the content of a message, or the way in which it is handled in service integration technologies.
Learning about service integration security
The security components of the service integration bus provide end-to-end security for sending messages from one application to another.
Learning about high availability and workload sharing
You can share workload between multiple messaging engines in the service integration environment. You can also make messaging engines highly available.
