1. A computer-implemented method for managing multi-availability zone (AZ) clusters of host computers in a cloud computing environment, the method comprising:
automatically detecting a degraded state of a first AZ in the cloud computing environment based on host failure events for host computers in a first cluster section of a multi-AZ cluster of host computers located in the first AZ;
scaling out a second cluster section of the multi-AZ cluster of host computers located in a second AZ in response to the detecting of the degraded state of the first AZ;
automatically detecting a recovered state of the first AZ based a successful scale-in operation of another multi-AZ cluster located partially in the first AZ; and
scaling in the second cluster section of the multi-AZ cluster of host computers located in the second AZ in response to the detecting of the recovered state of the first AZ.
