The four products discussed in this chapter are not the only implementation choices for achieving each of the desired architectural steps. As stated, they are referenced to provide a consistent view with the examples in the discussion of architecture in Part 3. It is beyond the scope of this book to try to reference all of the available product examples that could be implemented to achieve the architectural goals of the N1 Grid system. These examples provide insights into some of the options available to move forward and begin implementation of the N1 Grid vision.
It could be argued that implementation is really the first step. To many IT operations and administration personnel, nothing ever begins until it is actually being implemented. Although there is no argument that implementation is probably the most tangible and widely visible step of the process, it is by no means the beginning of a successful one. All too often, the IT environment is shaped by rapid implementation, without sufficient preparation and architecture to support it. The desire to get going should not override the necessary steps of preparation and architecture. Prepare, architect, and implement is the most efficient path to success the path to "realizing the N1 Grid vision."
