Since this solution represents the first-step in SOA transformation for ITSO Good, we select the generic profile of the Direct Connection runtime pattern to keep the proposed solution simple. Figure 10-4 shows the level 0 decomposition of the generic profile of the Exposed Direct Connection runtime pattern, mapped onto the Exposed Direct Connection application pattern.
