1. A computer-implemented method of facilitating management of an Information Technology (IT) environment, said method comprising: evaluating at runtime, by a processor, a pairing construct usable in managing the IT environment, the pairing construct being explicitly defined and including a first specified resource, a second specified resource and an explicit directive to act on the specified second resource, the evaluating at runtime comprising using one or more runtime characteristics of the IT environment to assess based on the then current runtime environment an effect of the pairing construct on a current runtime state of the IT environment to determine whether the pairing construct is to be used in runtime management of the IT environment; and conditionally controlling management of the IT environment based on the runtime evaluation of the pairing construct, wherein the conditionally controlling comprises using the pairing construct to manage the IT environment, based on the evaluating at runtime determining that the pairing construct is to be used.
