Description

WebSynergy, Web Services Integration Platform as EAI solution with MOM and Web Services technologies}

The present invention provides a new service called Web Services under a new web-based distributed computing environment.

Technology to make new systems as well as existing IT resources more effective

As a new concept of EAI solution that enables efficient integration

Web Services Integration Platform.

Since the conventional enterprise application integration (EAI) solution is an EAI vendor product specialized for the company that developed the product, another integration technology is required for the integration technology to secure various interfaces for B2B between companies. And even if a company integrates various information systems, it is always faced with many difficult problems of new / old combination of IT technologies such as preserving existing information system and building new system. The IT system built for the company's efficiency will be entangled and entangled like spaghetti, and the centralized integrated management will result in the company's competitiveness and efficiency.

Although many technologies related to the operation of information systems of companies are represented as EAI technology, these technologies also face another EAI problem in the B2B problem outside of the company or between companies even though they can perform in-house performance.

However, the new concept of integrated technology applying the standard technology of Web Services can be understood as a technical means of EAI and it is expected to make a big change in the existing EAI market.

Web Services standardizes the communication layer of EAI vendors

Value-added services such as workflow / transactional-integration can be provided, and corporate integration systems using WebSynergy make it easy to transition enterprise IT resources to Web Services.

In other words, it is much quicker and easier to build integration using Web Services and to add functions for Web Services based on EAI. With Web Services

This is because EAI is closely related to each other and its function can be amplified.

Recently, as Web Services has emerged as an e-business solution for in-house or inter-integration, many companies, large and small, are paying attention to Web Services. In particular, the infrastructure of Korea's most advanced high-speed communication network will accelerate the optimized web service environment, and the ultimate goal of inter-company web services will be realized as B2B. Many companies are planning to introduce Web Services to commercialize domestically developed products to enhance international competitiveness through import substitution effects and core technologies, and to create significant added value by possessing global IT solution technology that meets global standards. will be.

WebSynergy (Web Services Integration Platform), which is used as the name of the present invention, is a new concept of EAI solution that combines the technology and functions of web services.

WebSynergy is an end-to-end integration platform that manages key elements required to implement fully automated business processes. It is a web services integration solution based on messaging-oriented middleware (MOM) based integration broker. The MOM-based infrastructure has the following structural advantages. It provides guaranteed message delivery, message persistence, loosely coupled system design choices, and provides scalability, clustering, and support for an asynchronous programming model. Many companies have already introduced MOM, and the messaging solution provided by default in WebSynergy serves as a logical "backbone" for sending and receiving Simple Object Access Protocol (SOAP).

The expected benefits of combining MOM technology with Web Services include:

First is Reliability. MOM provides an efficient and realistic option for asynchronous and transactional systems. SOAP messages received using the MOM can be stored and delivered when the receiver is available, providing a guarantee of message delivery, persistence, and elasticity for ad hoc network connections.

Second is Scalability. It supports systems that meet the level of scalability and performance required by asynchronous designs only. JMS can also perform load balancing in managing and distributing SOAP message requests, in addition to increasing scalability.

Third is the consistent datd format. XML, which is the basis of web services, is a common data format that enhances MOM-based functionality and facilitates integration with other systems.

WebSynergy uses the JMS-based MOM to deliver messages as opposed to traditional Web Services using the simple HTTP protocol.

It can overcome the problems and limitations of 'ststeless', transaction, and message transmission and reception confirmation of HTTP method.

In addition, WebSynergy provides a large number of application adapters already implemented, and is a fully distributed architecture that combines peer-to-peer (P2P) architecture with Peer Server running on all nodes at the network end and Hub & Spoke messaging. It is a brokered P2P system that provides an ideal distributed computing environment. It overcomes the limitations of scalability and single point failure, which is a disadvantage of Hub & Spoke messaging method through P2P structure, and improves scalability and efficiency by performing major tasks such as data transmission and service deployment in each peer server. In addition, the management function, which is an advantage of the Hub & Spoke method, is introduced to define a rule between business processes in the central control module to support a single management of the entire business.

WebSynergy combines the benefits of the integration of both technologies by combining Web Services' technology to play a leading role in future integration between and among companies and the proven MOM technology deployed in many companies. It is a solution that can implement more efficient and completed EAI.

First, let's look at the combined model of MOM and Web Services.

First, we use JMS as a vehicle for SOAP.

HTTP, the transport used by other solutions for Web services,

It is simple, convenient and scalable due to the characteristics of stateless.

The lack of guarantees for message delivery is a matter of fact.

This is a problem for systems.

-HTTP is not transactional.

If an error occurs while delivering the message, the message forwarder

It is not possible to verify that the message was delivered to the recipient.

-Check whether the request is repeated even if the message is retransmitted

Can not.

Asynchronous messaging in MOM works with various Web Services Architecture models.

Programming styles are supported.

Interaction styles available to Web Services defined in WSDL

As follows.

1) Request / Response

Standard RPC-style web services use this request / response model.

On the WebSynergy platform, after reading SAOP Requests from one queue,

RPC-Web Services by placing a SOAP Response in another reply queue

support

After the client process sends a message to the Web Service,

Related reply message from

2) One-way

-The client sends a message to the web service and does not expect a response.

Not

3) Solicit / Response

The web service delivers the message to the client, which in turn

Sends an association reply message to the web service

4) Notification

-Web Service delivers a message to a client, but the client

Do not send answer message

Develop asynchronous Web Service Clients using styles 1) and 2)

Asynchronous Web Services development using styles 3) and 4)

Second, deploy MOM Applications to Web Services

1) If you already have messaging-based applications in your enterprise,

Convert applications to Web Services (create WSDL) and then

You can send SOAP messages on the WebSynergy platform.

(WebSynergy uses MOM and JMS to communicate)

Eventually deploy existing applications to Web Services.

2) XML schema and incomming SOAP message required by MOM system are WebSynergy.

It is mapped at runtime on the platform and is suitable for MOM-based applications.

Data converted to the format is placed in the appropriate message queue or topic.

3) Using SOAP and HTTP as a means of message delivery is a corporate firewall

It's a great way to extend your corporate messaging infrastructure out there.

In this way, mutual communication with external partners and customers

Build a B2B (B2B)

Three, MOM Applications Invoking Web Services

1) Traditional messaging that receives and processes messages from the MOM queue

Applications can call other Web Services for the process

2) After manipulating the input messages, using those messages as parameters

Invoke Web Services

Four, WebSynergy (Web Services Integration Platform) is an existing EAI integration broker

The following Web Services functions are provided in the functions provided by.

1) An application that can creat / test / deploy / pulish / manage web services

Providing an integrated platform environment

2) Easy and efficient web services of business partners for B2B

Provides the ability to register / use

3) The function to convert existing applications existing in the enterprise into web service

(Use the wrapper to virtualize existing applications

switch to web service)

Fifth, WebSynergy provides easy development and deployment of Web Services / Service Components.

Comprehensive integration providing an integrated development environment and framework for use

Solution.

1) Web Services standard support: SOAP, UDDI, WSDL, XML

2) Transactional Integrity Guarantee: The transaction of web service itself

Resolve defects with integrated broker ( WebSynergy ) transactional complement.

3) Auditing: Provides an efficient auditing mechanism to access and use web services.

To be accurately monitored.

6) Workflow Management: Define web services in one business process

Workflow management capabilities.

7) Enhanced security: Over various internet protocols such as HTTP / HTTPS / FTP / SMTP

Deliver messages with high security, easy to UDDI or other storage

Provide a secure bond. Policy management for accessing and using web services

Provide efficient security devices such as user authentication.

Lastly, it is a visual management tool function for the convenience of users. WebSynergy provides JAVA-based service / security management tool, distributed application writing tool, monitoring tool, peer server tool, etc. Users can simply integrate the existing system by drag & drop method using visual management tool. New services can be deployed and services can be modified in real time to monitor work process status.
