I'm new to DevOps and quite troubled financially but I desire to put websites that I now host on a shared server environment (CetnOS 12.x.x) on some cloud like DigitalOcean or Lindoe (but without using their droplets with ready OSs - I want to install the OS myself with Vagrant).
To have full automation of every upgrade possible (even OS itself say Ubuntu 18.04 to 20.04 or Apache 2.4 to Apache 3.4, PHP 7.4 to PHP 8.4 and so forth) I desire to use the VAD stack: Vagrant-Ansible-Docker.
DigitalOcean's cheapest plan for example is this 5$ plan:
25 GB SSD 1 virtual CPU 1 GB RAM 1 TB monthly data-transfer
I use the Drupal CMS (>=8) for generally all my websites (which are generally small-scale perceptional websites for small business of free-professions).
Each VPSE will contain up to 2 separate (non multi-stie) Drupal apps and each such app will usually take no more than 256 MB RAM, if I'm not exaggerating).
Can I base these such a X2 drupals installment on such 5$ VPSE with a VAD stack in decent performance? Or there's no way I could handle both VAD and X2 such Drupals on one such small VPSE?
