VM instances and Hosts information

We have a requirement in cloud discovery. 

  1. If the VM instances are switching between On and Off due to STOP status in AWS, how can we avoid creating the hosts for them. Currently, we saw that the VM instances are lesser in number than the hosts (brought by one integration).
  2. Also, if the VM instances are ON and Off, what should be the ideal period between which we should have the host. Say if the VM instance is off for 10 days. Do we need to bring the host for that as well.

I know the answer is how the client want to put this data into CMDB but have we faced these situations before.

Hi,

Why wouldn't you want to have the host VM represented in the CMDB? There is a Business rule that cascades the statuses from the VM instance to the host VM so they should be in sync.

How are you bringing VM instances - Cloud Discovery ?

Conceptually --> When you discover a virtual machine in one of these cloud providers, two records are related to that virtual machine. One is called VM Instance, AWS calls it instance and Azure calls it of Virtual machine. The other record corresponds to the guest VM also referred to as Host VM or simply the OS Server.

 

VM instance must have a corresponding host - 

 how can we avoid creating the hosts for them--> As u said it one Integration check the query which is fetching Hosts.

 

Point 2- How many days its totally a environment specific number . One question after how many days of a VM instance is off then Its resources are claimed?
