(I know that this is about selfhosting, but I am forced to use cloud services due to it not being viable to selfhost because of DSL internet speeds in my house, and I need this to be accessible outside my home.)
I recently made a Linode account (and got the free credit), and I am planning on only paying $5 a month if I can. I noticed that Nextcloud AIO (from Linode “Marketplace”) ran very well on the lowest shared CPU plan (1GB ram, 25GB storage, 1 CPU core (CPU seems to me an AMD Epyc?)).
Will it be okay for me to host a Wordpress website and a Nextcloud instance from the same server? I will be using Docker/Podman, and only I will be using the Nextcloud instance.
Ahahaha
Convincing argument, but unfortunately a cursory Google search will reveal he was right. There is very little CPU overhead. The only real consideration is a bite extra storage and RAM to store and load the redundant dependencies of the container.
You’re also ignoring the amount of work the kernel has to do to shift UUIDs around, the resources that the docker daemon itself uses and amounts of redundant stuff to make sure those processes are running that would usually be handled by systemd on a clean system. Yes, containerization is much better nowadays but still overhead.
