Learning to manage a self hosting environment is a great skill to learn but I would point out there are plenty of people on HN who have these skills but prefer to rely on managed providers.

Even including people who manage infrastructure professionally I would guess that the vast majority of them don't fully self host their own file storage, email, calendar etc.

Obviously you may have your own unique reasons to want to do this but just know that those who know the full extent of what is required to do this safely and resiliently don't feel it's worth the hassle or effort.
