Description: The ‘Last Known Good’ (LKG) is a fundamental concept in resource management, especially in the context of cloud computing. It refers to the last known state of a resource that was functioning correctly before a change or update that may have caused a failure occurred. This state is stored to allow system administrators and developers to revert to a stable configuration in case a new deployment fails. The importance of LKG lies in its ability to minimize downtime and ensure service continuity, as it allows for the quick restoration of a resource to its previous operational state. In a cloud environment, where resources can be dynamic and changing, LKG acts as a safe reference point, facilitating disaster recovery and change management. Additionally, the use of LKG promotes safer and more efficient development practices, as teams can experiment with new configurations without the fear of losing access to a functional state. In summary, ‘Last Known Good’ is a critical tool for stability and resilience in infrastructure management.
