I need help with my SOA model. The enterprise systems layer should include all of your physical components, systems, databases, other infrastructure, including a presentation of a cloud solution represented by a cloud image, and how all of these in this layer are connected to each other using arrows. The business process layer should include all of your business processes such as accounting management process, business audit activity process, and all other processes that you can consider that should be shared among 4 locations. All the interconnectedness to be shown by arrows among business process in this layer component. Once this is completed, all the other connections have to be drawn with arrows among all the components among the 9 layers.
