Research into computing resource markets has mainly considered the
allocative fairness of market mechanisms. It has not been discussed how a large
variety of resource types influences the market liquidity. Markets containing
large numbers of buyers and sellers for heterogeneous resources suffer from a
low likelihood of matching offers and requests. Traders therefore have the high
risk of not being able to trade resources. We suggest a solution that derives SLA
templates from a large number of heterogeneous SLAs in the market and, by using
these templates instead of the original SLAs, facilitates SLA mapping. The
usefulness of this approach is demonstrated through simulation results and a
comparison with an alternative approach, in which SLAs are predefined.
