Offshore Hosting Guides<\/span><\/p>\n

What developers actually want from a host<\/h2>\n

Not a dashboard. Root access, a predictable machine, an IP that is not on a blocklist, and a provider that does not suspend an account because an automated scanner found something it did not understand.<\/p>\n

Offshore VPS hosting tends to score well on all four, and the jurisdiction is often a side benefit rather than the reason. This page covers what to look for and where the traps are for an application rather than a website.<\/p>\n

The four requirements<\/h2>\n

KVM, not containers.<\/strong> Docker needs real virtualisation to work properly, and a container based VPS either blocks it or runs it degraded. Memory on a container plan is also oversellable, which means your numbers are aspirational. Check with systemd-detect-virt<\/code>, and see why KVM matters<\/a>.<\/p>\n

A console in the panel.<\/strong> VNC or noVNC, something that works when SSH does not. You will lock yourself out with a firewall rule at some point, and a console turns that into two minutes instead of a support ticket.<\/p>\n

Snapshots.<\/strong> Take one before every risky change. Being able to roll back a bad migration in ninety seconds changes how confidently you work.<\/p>\n

A clean IP.<\/strong> Check it against major blocklists before you build anything on it. A recycled IP can arrive with a history that breaks your outbound mail on day one.<\/p>\n

Running the stack<\/h2>\n

Whatever you run, a few things are worth getting right early because they are painful to retrofit.<\/p>\n

Bind services to localhost.<\/strong> Postgres, Redis, MongoDB and Elasticsearch all default to a broad bind address in some packages. Anything on 0.0.0.0<\/code> is reachable from the internet the moment the firewall lets it through, and unauthenticated Redis on a public IP is compromised within hours.<\/p>\n

ss -tulpn | grep -v 127.0.0.1<\/code><\/pre>\n
Run that after any install. Everything in the output should be something you deliberately exposed.<\/p>\n
Use a reverse proxy.<\/strong> nginx or Caddy in front, your application on a local port. That gives you TLS termination in one place, easy multi-app hosting, and somewhere to add rate limiting.<\/p>\n
Run the app as its own user<\/strong>, not root. Then a compromise in the application is not a compromise of the machine.<\/p>\n
Set up the firewall before the app is public<\/strong>, not after. Our firewall guide<\/a> covers the order that avoids locking yourself out.<\/p>\n

Deploys and staging<\/h2>\n
Even solo, deploying by editing files over SSH stops being viable quickly. Two habits pay for themselves within a month.<\/p>\n
Deploy from git.<\/strong> Pull on the server, or push to it, but have the state of production be something you can identify by commit. When something breaks at 11pm, knowing exactly what changed is the difference between a fix and an archaeology session.<\/p>\n
Have a staging environment.<\/strong> A subdomain with its own database, where migrations run before they run on real data. Our staging guide<\/a> covers building one that cannot accidentally write to production.<\/p>\n
Add a systemd unit for the application so it restarts on failure and comes back after a reboot. Then actually reboot the server once and confirm everything returns. That test finds more problems than any amount of reading config files.<\/p>\n
Transactional email<\/h2>\n
This catches out nearly every SaaS project on a new VPS, so it is worth flagging clearly.<\/p>\n
Many providers block outbound port 25 by default to limit spam, so your application’s password reset emails silently fail. Even where it is open, a fresh IP has no sending reputation and mail from it lands in spam.<\/p>\n
Do not fight this. Send through a dedicated provider over port 587 with proper authentication, and set SPF, DKIM and DMARC on the domain. Our email guide<\/a> covers the records. Trying to run your own mail sender on a new IP is weeks of work for a worse result.<\/p>\n
Scaling<\/h2>\n
Scale vertically first. Doubling the RAM on one machine is an hour of downtime; splitting into multiple machines is an architecture change. Most applications never need the second one.<\/p>\n
When you do split, the usual first move is putting the database on its own server, because databases want memory and applications want CPU, and separating them lets you size each properly.<\/p>\n
Before any of that, check you are not simply short on one resource. Load average against core count, available memory, and the wa<\/code> figure in top<\/code> will tell you which. Our sizing guide<\/a> covers reading them.<\/p>\n
