1. A compute node of a cloud computing cluster, the compute node comprising: a data collection module to collect performance data indicative of cache memory contention of the compute node; a contention score determination module to determine a contention score as a function of the performance data, the contention score to include a contention metric and a contention score level indicative of the contention metric, wherein to determine the contention score comprises to determine the contention score level by comparison of a rate of cache misses per reference number of instructions to one or more threshold values, wherein to determine the contention score level further comprises to (i) compare the rate of cache misses per reference number of instructions to a low contention threshold value, (ii) set the contention score level to a low contention level in response to a determination that the rate is less than the low contention threshold value, (iii) compare the rate of cache misses per reference number of instructions to a high contention threshold value, (iv) set the contention score level to a medium contention level in response to a determination that the rate is greater than or equal to the low contention threshold value and less than the high contention threshold value, and (v) set the contention score level to a high contention level in response to a determination that the rate is greater than or equal to the high contention threshold value; and a communication module to store the contention score in a cloud state database, the cloud state database accessible by a cloud controller of the cloud computing cluster.
