Enterprise Service Bus (hereinafter referred to as ESB) is the basis of SOA architecture. As the pillar of the information transmission in the SOA architecture, it can provide high-speed information transmission channels for various operation systems. ESB can integrate the data across existing operation systems through ways of atomic transaction and portfolio transaction, eliminate technical differences between different applications, enable different application severs to coordinate operations and achieve the communication and integration between different services. All application systems can be integrated into ESB platform through adaptors of service providers and requesters so as to achieve the connection between services, production and consumption of all operation systems.
Background
Traditionally, enterprises use point-to-point approach to achieve application integration, which has definitely led to the netted structure of enterprise IT architecture, and then the complicated and rigid application architecture, high maintenance costs and slow market response. Galadin ESB can effectively solve those problems.
Functional Modules
(1) Core Bus
In the whole Galadin ESB architecture, core bus serves as the master control center or the core platform on which all the service scheduling, routing control and the management of service portfolio and service consistency are played out.
(2) Adaptor
In the whole Galadin ESB architecture, adaptor is used to connect the core ESB platform with application systems. As the structure of application systems varies from each other, there are usually some legacy systems and ESB platform only provides a uniform interface for the connection with application systems, adaptors are needed to shield the inconsistency between ESB platform and application systems.
(3) Management Module
To ensure the long-term sound running of Galadin ESB platform requires the support of full-fledged background management functions including a management module which can continuously release new services, solve all sorts of possible problems timely and deal with service configuration information.
(4) File Transfer
In order to ensure the reliability and efficiency of bulk transfer of files or business data, it is required to set up a set of tree network platforms for file transfer which should be separated from the specific operation applications and ensure the asynchronous transfer of various business data files.
Features
(1) Dual communication interface
MQ and XML are applied to transfer data both inside and outside the ESB. Moreover, the system supports both synchronous and asynchronous information transmission and therefore meets the demand of both synchronous and asynchronous transactions.
(2) Various communication approaches
The corporate integration platform the model of supports point-to-point communication, publishing and subscribing.
(3) Powerful business dealing capacity
Galadin ESB platform can divide users’ applications into several working units. As data updating in each working unit is logically related, the completion and rollback should be done simultaneously so as to maintain data integrity.
(4) Supporting heterogeneous platform
Given there are various hardware platforms and operating systems, complicated network environment and various software development and operation contexts in corporate applications, the corporate integration platform provides online trading and communication interfaces that can accommodate the complex heterogeneous platforms and shield the differences in bottom communication protocol and coding approach for application system so as to enable the system to focus on the development of business logic.
(5) Offline batching and transfer
Batch files can be transferred through customized server for transmission and by designating fixed transmission interface.
Key Benefits
Galadin ESB is a basic integration platform for application systems and services of enterprises and is a basic IT platform for the information exchange among a large number of heterogeneous systems, hence serving as a conveyor belt. Based on the service bus, it is possible to achieve release and sharing of standard services and flexible and efficient information exchange, to improve the business flexibility and the speed of market response and therefore to enhance the competitive edge of enterprises. The specific benefits are as follows:
(1) Setting up enterprise service bus in heterogeneous applications can realize standard connection with applications as the first difficulty in application integration is the large number of heterogeneous interfaces of heterogeneous systems. If Galadin ESB is applied to achieve the interaction among these applications, the application interfaces do not need to have a same protocol or communication interface since Galadin ESB is responsible for shielding the heterogeneity in the protocol and data structure of interfaces.
By adopting loose coupling and by isolating the application logic function of operation systems and the integration function of the integration platform, Galadin ESB can reduce the complexity of the interconnection and intercommunication of systems, improve the capacity of service interaction across systems and organizations of enterprises, maximize the IT asset value of enterprises and respond to the demand of market business in a flexible and efficient way.
As for business changes, Galadin ESB supports processed arrangement of services. It can achieve separation of business logic from integrated logic and flexible arrangement among services and can modify service arrangement to adapt to the new business if changes in the demand inside an enterprise cause changes in integrated business.
In terms of network environment, based on the standard service packaging of Galadin ESB and the intelligent routing technology in the interaction among services, Galadin ESB provides unique arrangement models of “autonomic” and “federal” distribution and therefore achieves reliable interaction among services in an open, dynamic and changeable network environment and reduces the cost of information sharing inside the enterprise.
Potential Client
As the enterprise application integration platform of ESB can make integration of heterogeneous systems less complicated, reduce the degree of coupling among various operation systems and facilitate the integration and disconnection of operation systems, Galadin ESB platform is applicable to all kinds of enterprises who need integration of various systems.
