Optimize vps cost
actually I have 15 vps (small plan on server4you + 2 Medium plan) and 5 ssd speed plan on contabo,
I use plesk for panel and i buy for each vps a web admin plan.
My site are built in prestashop or wp.
What do you suggest? maybe buy 2-3 big dedicated server and move it all in?
Also i need to semplify management with me.
