1. A computer-implemented method comprising:
obtaining first monitoring data associated with a host computing device, the first monitoring data indicating a load on the host computing device;
updating a first score associated with the host computing device based at least on the first monitoring data to be a second score, the second score reducing a probability of the host computing device being used to host a new customer instance;
calculating a hash value based at least on at least one impairment condition in the first monitoring data;
matching the hash value to at least one fingerprint;
causing at least one remediation action associated with the at least one fingerprint to be performed on the host computing device;
updating the second score based on the at least one remediation action to create a third score, wherein the at least one remediation action is associated with a score reset value, and wherein updating the second score based on the at least one remediation action includes updating the second score to be the score reset value to yield the third score;
obtaining second monitoring data associated with the host computing device, the second monitoring data obtained following a reduction of the load on the host computing device; and
updating the third score based on the second monitoring data to create a fourth score, the fourth score increasing the probability of the host computing device being used to host a new customer instance.
