I started with hosting from website.com (thinking they were some authority), got a reseller plan from HostGator (before EIG), and then got a cheap server from The Planet. The Planet was acquired by SoftLayer, then by IBM Cloud.
Over the years, I’ve hosted for my clients and explored expanding but never bothered. Hosting for clients reduces my costs for hosting all my sites.
Dedicated server. It’s not so expensive when you have multiple projects, and it’s easier for me to monitor and automate everything.
For WordPress, I use SiteGround; for everything else, AWS.
In my opinion, Vercel is the best choice. You can host your web applications conveniently. Vercel supports everything you need, including domain management, analytics, logs, performance, and databases.
Hetzner, Digital Ocean, depending on the customer’s requirements.
Vultr, OVH and several idle low-end boxes I’m unsure what to do with.
I purchase the domain for them; they pay for it. Hosted on render.com along with the PostgreSQL database. Super easy.
I rent a host on Hetzner for about 8€ per month, serving Wagtail CMS instances from there, deployed with Docker, with a Caddy proxy server. The frontends are deployed to Cloudflare and built on every change via a webhook, so the Hetzner server is never hit unless there’s a site change. Builds take about 1 minute, so no real issues for the clients.
