Summary

In this chapter, we have gone through two important features of Proxmox—live migration and HA. Using live migration, we can shift our services to other machines with minimal system downtime when we find that the system resources on a cluster node are almost fully utilized. This allows us to have better resource management. With a VM running with HA, the system downtime can be minimized, and the system administrators are not required to monitor the system 24/7 on their own.

In the next chapter, we are going to see how to import our existing operating systems to our Proxmox cluster to enjoy the functionalities we just mentioned.
