Inventory change management (integrated inventory history inquiry)

It collects the status at the time of change of cloud resources, provides change comparison, and change tracking/management functions.

Easy to track arbitrary tasks
It is easy to trace the cause when a failure occurs due to a change in resources.
It is easy to trace the cause of cost increase when cost increases.
Easy to view resources created, modified, or deleted within a period
By registering change events as change history during operational work, it is easy to track what changes were made at the time of change work.

1. Change Management

1-1 Change Event

Change Event: This refers to the state of a resource at the time it is created/deleted, or the state of a resource at the time when the property managed by CloudXper is changed.

1-2 Change History

Change History: This is a feature that manages change events in a group, meaning that it is a feature that allows the person in charge of the change to track and manage "why" the change was made.

1-3 Notes

If change events are not collected among AWS EC2 Instance resources - If creation and deletion occur as needed through a short life cycle, operation through change events is not easy, so they are not collected.
1. If the AWS EC2 Instance resource contains a specific tag key
  1. Auto scaling tag key: aws:autoscaling:
  2. EMR tag key: aws:elasticmapreuce:instance-group-role
2. Instance with AWS EC2 Spot Lifecycle
