Question: Which feature in the oracle cloud infrastructure compute service enables users to migrate running instances between different physical servers?

One of the benefits of using Oracle Cloud Infrastructure (OCI) Compute service is the ability to migrate running instances between different physical servers without any downtime or data loss. This feature is called live migration and it allows users to move their workloads to optimize performance, availability, and capacity.

Live migration works by transferring the memory and CPU state of the instance from the source host to the destination host, while maintaining the network connectivity and storage attachments. The process is transparent to the instance and does not require any changes to the operating system or applications. The instance continues to run during the migration and does not experience any interruption of service.

To use live migration, users need to enable it for their instances in the OCI Console or through the API. Users can also specify a maintenance policy that determines how their instances are handled during planned maintenance events that affect the physical servers. Users can choose to receive notifications and manually migrate their instances, or let OCI automatically migrate them when needed.

Live migration is a powerful feature that enhances the flexibility and reliability of OCI Compute service. Users can leverage it to optimize their cloud infrastructure and ensure high availability for their critical workloads.
