notes point-to-point topology

Point-to-point topology enables applications to communicate directly with one another. This is
useful when synchronous communication and persistence are required. Applications with pre-
built integration for ERP applications use this topology. Too much of the point-to-point integration
in an organizations IT structure leads to inter application. Benefit of this topology is its ability to
take full advantage of the context and semantics of the original data as it is transformed into one
or more target structures. The major constraint for this topology is if there is any change in either
of the applications like up gradation, etc then the whole integration has to be changed.

pipeline topology

Pipeline topology is useful if dynamic configuration is not required and multiple pipelines are
independent of each other. The information flows will be based on the First In First Out approach.
This is a very simple level of integration.

network topology

Network topology is the best option available if there is a lot of asynchronous activity and
independent transactions must coexist with one another. For this topology to work well, the
interfaces must be well defined and robust. If there is a snag at the interface level then the entire
network communication can fail.

B2C business.

6.15 eai solution

The solution for EAI consists of technology for supporting both data level and business model
level interfacing. Design patterns are used to identify, categorize and reuse interfaces so as
to ensure that the selected method of application-to-application communications is the best.
Effective EAI solutions reduce the up front costs of implementation and provide open, seamless
integration of business processes with any type of technical infrastructure. This also results in a
Zero Latency Enterprise.

6.15.1 requirements for effective eai solution

1. IT strategy needs to be mapped out according to the business strategy and the objectives
2. Complete understanding of the business processes data models and the supporting systems
and applications currently in place
3. Planning for the whole process’ right from need identification, vendor selection to
implementation and future requirements
4. The EAI architecture, viz., process models and integration requirements, has to be
formulated from the IT strategy and architecture
5. Evaluate the EAI tools and the vendors

6. Accountability and ownership has to be established
7. Evaluate the solutions and the scope of integration covered by the technology
