Replicated System

Figure: Cost of Replicated Computations

Consider the simplest replication of a system consisting of two components with n replications. The traditional architecture and the noemic architecture are in Figure gif on page  gif.

Let a be the cost of each component in the calculation. Let c be the cost of communication. Let n be the number of replications.

The comparison results are shown in Table gif on page  gif.

Replication does not help the traditionally built application when it comes to elaboration tolerance.
