VPS with 48 or 64 GB RAM: several services on one machine

A VPS with 48 or 64 GB of RAM can host several services on one machine: a website, a database, n8n, bots and a small game server. To do so, isolate each service, set its memory limit and monitor everything. As of 7 November 2026, the Performance plan gives 48 GB for 21.99 € and the Pro plan 64 GB for 34.99 €.

• One service per container: a failure or a leak stays confined.
• mem_limit sets the maximum memory of each service.
• docker stats and free -h show the real consumption.
• The Performance plan gives 48 GB of RAM at 21.99 € as of 7 November 2026.

Split services into containers

Rather than one system that handles everything, place each service in its own container, with its own Compose file. A reverse proxy such as Caddy receives web traffic and routes it to the right service. A failure or a memory leak stays confined to one service.

• One folder per application, with its compose.yaml file and volumes.
• A single reverse proxy for websites, so only ports 80 and 443 are open.
• Databases on the internal network, never published on the internet.

Set a limit per service

Without a limit, a container that grows can take all the memory and drag the others down. In the Compose file, the mem_limit key sets a ceiling, and cpus limits the share of processor.

• Example: mem_limit: 4g for a game server, 2g for a website, 1g for a bot.
• Keep the sum of the limits below total RAM, leaving a margin for the system.

Monitor RAM and swap

Once the services run, check their consumption regularly. docker stats gives the memory of each container, free -h that of the machine. If swap grows, one service uses more than planned.

• docker stats --no-stream: an instant snapshot of each container.
• Note the peaks over a week before adding a service.

Back up before each addition

The more services there are, the more an error costs. Before each new addition, back up the volumes and databases. The method is detailed in the article backups and the 3-2-1 rule.

• Test a restore at least once, on a copy.
