Combining the Services
10.1 Introduction
In Part Two of the book we started out with the architecture of the Service Availability (SA) Forum interface specifications and the information model used in systems compliant to the specifications. These chapters together painted the overall picture of such systems and provided the basics for the discussions to follow.
In subsequent chapters we looked at the different service specifications in details starting from the platform level up toward the applications and the management functionalities.
Our suspicion is that these chapters even in this format presented quite a bit of challenge for readers not particularly familiar with the domain. Nevertheless we can assure these readers that reading the specifications themselves would have been a more daunting task.
In any case, we have done the decomposition and the analysis of our architecture and this is the point where we need to pull everything we learnt about our system together and do the synthesis.
We can look at our system from the perspective of the designers and the developers of an application, who need to build an application that will be able to provide its services in a highly available manner; and for that purpose who want to take advantage of the SA Forum specifications and their implementations by using the SA Forum services instead of developing the same functionality from scratch.
