Abstract: Server management data describes observed operating condition of a pool of spare servers. Based on a demand forecast of a specific target system, a dynamic allocation period is determined as a period during which the target system needs additional server resources to handle an expected demand. Based on the dynamic allocation period and server management data, a set of allocation candidates are nominated from the spare server pool, by eliminating therefrom spare servers which are likely to fail during the dynamic allocation period. An appropriate allocation candidate is then selected for allocation to the target system, such that the selected candidate will satisfy a specified requirement during its allocation period.
