Answer:
I would recommend HA.
Step-by-step explanation:
HA stands for high availability. High availability is recommended because it has the power to be consistent or operational for a great amount of time. It is one of the features of a system whose objective is to make sure that operational performance is higher than it would be normally. Such a system works by having multiple components and checking regularly to see if each of the components are working fine, in a situation were it isn't, a component that is working well will be switched to.
