2.The load of each tenant follows either the temporal characteristics of a working week or the characteristics of a demo system (cf. Sect. 2.4);

3.Each tenant has a realistic size; and,

4.Variations in load differ sufficiently among tenants.

The latter requirement is challenging. On the one hand, our goal is to create new tenants with a realistic load pattern. This requires that the pattern resembles the original tenants. On the other hand, too much resemblance among tenants is not desirable, since as a result the aggregate load in the cluster would be smoothened (cf. Fig. 1.1) as the total number of tenants is increased. Our bootstrapping technique takes this trade-off into account, as we shall see in the following.
