Unsure about how to split services into multiple droplets


Im currently running my entire setup on one large dedicated server and Im planning to move everything into multiple droplets. The reason for that is that I mainly wanna give other people access to specific services.

My Services:

  • 4+ Wordpress Sites (All Sites are very small) [Apache + MySQL]
  • Java powered Web Crawler
  • MySQL [For Discord Bot + Web Crawler]
  • Discord Bot

Choice A:

  • 1# 2GB Droplet [4+ Wordpress Sites] + [MySQL]
  • 2# 2GB Droplet [Web Crawler] + [MySQL]
  • 3# 1GB Droplet [Discord Bot]

Choice B:

  • 1# 2GB Droplet [4+ Wordpress Sites]
  • 2# 1GB Database Droplet
  • 3# 1GB Droplet [Discord Bot]
  • 4# 2GB Droplet [Web Crawler]

My Question:

Im not too sure whether I should install a mysql server on multiple droplets or If I should have one seperate database droplet.

NO WAY, I never recommend to have different CMS 2 sites on same server & database. Everything nowadays, comes down to the safety and security of web-systems.

You’d better keep every different CMS separated. because if one site hacked, everything (other sites) becomes accessible too.

I wouldn’t use a single droplet for your database. I’d recommend having 2 identical droplets with MySQL replication using master/master setup.

This will give you a resilience in the event of a server failure, and will allow you to take a DB server offline for upgrades (i.e. patching) without causing an outage.

Im thinking about maybe installing a mysql server instance on the website droplet since those websites are pretty much completely seperate from the rest.
