VDS-M: room for an application and its database

VDS-M is the right size once an application is serving real users: a shop, a CMS with steady traffic, an API with its own database, or a handful of small services run by one team.

The deciding factor is that the database and the application both want memory at the same time. That is where VDS-S starts to feel tight, and it is exactly what this size is built for.

CPU and RAM are reserved for you rather than shared with other customers on the same host. Response times stay predictable at peak, which is the practical difference from an oversubscribed VPS.

You get full root access: your own distribution, your own packages, your own firewall rules. No control panel is imposed on you.

RAM and disk are chosen at checkout. Leave headroom on memory for database caching — that is the first place a tight spec shows up as slow queries.

If you run several services side by side or expect sustained heavy traffic, VDS-L is the better fit. Moving up later does not mean rebuilding the project from scratch.
