Abstract

A method and system for consolidating N elements of an enterprise IT structure that consists of L elements (N≦L). All combinations of M elements of the N elements are generated (M<N). M is a specified positive integer of at least 1 and less than N. One or more pairs of combinations selected from all of the combinations are ascertained such that each ascertained pair consists of IT structures S1 and an IT structure S2 which are specifically congruent with respect to each other. Specifically congruent means composition congruent, topologically congruent, interface congruent, composition congruent and topologically congruent, composition congruent and interface congruent, topologically congruent and interface congruent, or fully congruent. At least one pair of combinations selected is consolidated. Consolidating each pair P reduces a goal function G that is a function of a total cost of ownership (TCO) of the enterprise IT structure.
