I am Maqbul, I am running multiple sites from Godaddy Deluxe Hosting. Sometimes my site is down for a while and saying "exceeds resource limits". So please kindly suggest me to choose product, Whether to choose Resource or by dedicated hosting.
And if i upgrade from shared to dedicated is this problem solved or not
your issues won't necessarily be fixed by moving to dedicated hosting. Your issues will only likely be resolved by purchasing more data space or reducing data, as it sounds like you are almost at your limits.
A chat with support will be valuable because you don't want the same problem in six months time.
It's either this solution or putting up with occasional downtime, although this isn't going to make you popular with your clients.
