Basic Concepts Of Architecture Messaging MOM (Message Oriented Middleware) shields the inherent complexities like OS, Network topology and protocol, programming language from the applications Application Communicate with each other using a series of messages. Applications deposits (publish/request) and retrieve (subscribe/response) the messages from queues (a special message holding area) Message Processing Synchronous Processing Asynchronous Processing – enables applications to immediately return to normal processing after generating request without having to wait for

Basic Concepts Of Architecture Message Delivery Volatile – fast Messages are stored in memory Messages are lost if the system shuts down Guaranteed – slower Messages are stored in a persistent queue Messages are guaranteed to reach to its destination regardless of network reliability, target system’s availability, bandwidth limitations

Basic Concepts Of Architecture Message Sharing - Publish and Subscribe Sending documents out for potential subscription (do not need to know who receives them) Published documents are routed to the subscribed clients When a client publishes a document, a “subscription pointer” to the document will be placed in the inbound queues of all subscribers Each subscriber uses its pointer to extract a copy of the document from the queue There can be multiple subscribers to single published message

BPM The Process designer must be an easy-to-use and intuitive tool for process/business analysts to completely describe a Process. Process Simulator enables the process analyst to perform as-if scenarios and to find out the bottle-necks in the process before deploying the process. Process Executor is the Engine which manages the behavior ( persistency, integrity and flow ) of the Process at run-time.Process Facilitator is the work-portal and it provides the interface for human interaction Process Monitor collects data on each process instance and allows the Business Owners to keep an eye on the Business Processes.Process Analyzer enables the business process / function owners to create multi-dimensional enterprise dash-board.

How it works ?

BAM “BAM defines the concept of providing real-time access to critical business performance indicators to improve the speed and effectiveness of business operations.” BAM is largely born-of , and is reshaping, two previously distinct technology markets: Analytics and decision making of Business intelligence market Real-time and business process linkage of Enterprise Application Integration (EAI) BAM focuses more on what is happening than on what has happened or might happenBAM sits in-between the historical and analytical focus of BI and the forward business planning of Corporate Performance Management

webMethods Product Suite

webMethods Product Suite This diagram provides logical view of recommended B2B solution architecture I.e. there is no co-relation to the physical machines. Reverse Proxy Server – Use only for routing inbound documents. No need to open internal firewall ports to DMZ. Send outbound documents directly to Partner location (or DMZ file server for partners to pick up) Reverse Proxy Server – No need for IS clustering as the reverse proxy servers only route the documents to internal IS. Use pseudo-clustering Internal DMZ Facing IS Servers – In IS Cluster with shared Repository Server Configuration. Hosts Trading Networks packages and connects to a Trading N/w database.

webMethods Product Suite Trading n/w database – configuration information - Partner Profile - TN Document type definitions (representing XML, Flat file, EDI, SWIFT) - Processing Rules [Routing] - Certificates - runtime information … transaction analysis logs used for document tracking. Integration Server for Enterprise Application – Acts as adapter run-time for integration with enterprise applications. As best practice, this IS may be on same machine as enterprise application or on a separate server close to the application. The IS performs - operations on the end-application via adapters - enables data exchange between the enterprise application and integration messaging backbone (broker) - provides transformation of data from application format to canonical (and vice-versa).

webMethods Product Suite Audit Log database and Trading Networks database will be setup on Oracle/SQL Server database instance. Audit log – used to track execution of the services such as adapter services, flow services as well as business processes on the integration servers. Messaging Backbone comprises of multiple broker servers in hardware cluster for high availability.
