administrative effort: VPS vs. shared hosting
I am currently in a shared hosting plan. Am considering upgrading to a VPS plan. Can anyone tell me if there are additional administrative or maintenance efforts I have to consider if I move to a VPS plan? I am running a site with a shared SSL certificate, that includes PHP and MySQL apps. Also a site with a WordPress install. I have some CRON jobs running PHP scripts. One of my PHP apps occasionally sends out an email or 2, and allows for an occasional file upload. Would a move to VPS cause me to have to structurally change my PHP apps? (I only do relative URL links, not absolute). So do I need to do my own backups in a VPS plan, install my own SSL certificate when needing to be renewed, etc. etc. Thank you in advance.
