Question about multiple containers, with load balancer on DO

we’re expecting high influx of users, but in spurts. We are having some members migrate from a fairly large community and my investors were insistent that the servers should be able to handle ally types of traffic; one of the main problems of the other site was server reliability. I realize maybe the load balancer might be overkill at this point in time but I thought it would atleast help to make sure resources are provided more equally…also I thought it would be better maintainability-wise to have my basic architecture in place already…
