Migrating the VM to a different host is a common technique to improve the performance of a VM that is suffering from resource contention or contention on the physical server. By moving the VM to a different host, the administrator can:

Reduce the stress and load on the original host, which may be under stress due to a peak usage workload.

Increase the availability and reliability of the VM, which may be experiencing slow performance due to resource contention or contention on the original host.

Balance the workload and resource utilization across multiple hosts, which may improve the overall performance and efficiency of the cloud environment.

Migrating the VM to a different host can be done manually or automatically, depending on the configuration and capabilities of the cloud platform. Some cloud platforms support live migration, which allows moving a VM to a different host without interrupting its operation or service. Other cloud platforms require shutting down or pausing the VM before migrating it to a different host .

Peering is a networking technique that allows direct and private connection between two or more cloud networks without using the public Internet. Peering can help the cloud administrator improve the connectivity within the regions by reducing the latency, increasing the bandwidth, and enhancing the security of the data transfer. Peering can be implemented between VPCs within the same region or across different regions, depending on the CSP’s offerings and the customer’s requirements. Peering can also help reduce the network costs by avoiding the use of the Internet gateways or VPNs.
