MSK Failover and OS Patch


IHAC, the customer experienced a failure due to OS Patch failure while using MSK. Our advice on this is to scale up MSK. Here, the customer asked additional questions.

  1. What is the minimum period of notice (e-mail) for MSK Patch (a week ago?)?
  2. Is the problem caused by the number of partitions or is there any other possible case?
  3. The customer is using MSK through a triple redundancy configuration(use multi-az with three instance), so was it impossible to avoid failure through this? I am wondering how to respond when OS Path fails or how to set an alarm.

If you have a good guide, please let me know.
