Architectural teams or development teams should investigate more than one
architectural options for their ecommerce systems. The proposed options then
should be evaluated in a systematic fashion by applying a set of well-defined
criteria. Without subject evaluation of various options, we may end up with
choosing the architecture we prefer, not the architecture most suitable for
your business requirements.
Cost of Initial Development
The cost of initial implementation is usually a small portion of your total cost of
application development. Application evolution and maintenance incurs large portion
of the total cost. This is specially true for the development of ecommerce systems
since the scope of the system changes continuously. Ecommerce systems generally
prefer the architectures which require lower initial investment.
Complexity of Development whether your IT staff
have the right expertise to implement the architecture in a cost-effective way.
Performance of the Application whether the
applications based on the architecture can deliver the performance to meet
your business needs.
Evolution of the Application whether the architecture
is flexible enough for addition of new functionality. What is the cost for application
enhancement?
