Best option for live migration (only lxd vs lxd with docker vs just docker )

[Sarthak Sharma]

Hi, I am new to the field of containers, and need to migrate a framework running on a system to another system (keeping all the configuration files and all its other dependencies) on runtime with minimum drop time and maximum support available. 

I can use KVM's live migration but using containers I think will be better and faster. Plz help me with the best alternatives to be used in this case which also have a well documented implementation as I know that it can be done using the "checkpointing and restore" functionality using dockers but how to actually configure it to do so is still a concern.

Thanks. :)
