Designing with Patterns Synopsis: In this exercise, your task is to propose a design for the Messaging Infrastructure layer of the new Brokerage Information System (BIS) for the Bizco company. To accomplish this, you must select a pattern and instantiate it, modifying the architecture to meet the quality attribute requirements for the company BizCo Business Goals To establish BizCo as the industry leader in brokering appraisal for commercial and residential properties.
