So we offer this as an introductory opinion on how you might want to design your
overall SOA Architecture. Feel free to agree or disagree with parts of it as you see it.
However, we would stress that you need to go through the process of defining your
architectural approach to SOA and that you continue the process of refining it over
time, based on the experience and requirements of your organization.
With that caveat out of the way, the following diagram illustrates one way of
organizing our services into distinct layers within our overall architecture:
We can see that this breaks into five layers. It should also be apparent that all layers,
except the top layer, actually provide a set of services to the layer above and typically
do this by building on the layer beneath it.
