The architectures presented here are by no means exhaustive of the choices available to you when inventing your own technical infrastructure. We’ve put forth these to demonstrate some of the various ways the pieces and parts of these services can be put together. The chapters that follow present detailed examinations of each of the disparate services available. Mapping these solutions to the nonfunctional requirements that are specific to your application and enterprise will yield a solution that may be similar, but most likely not identical, to those we’ve presented here.
