How shared Java hosting works
In shared Java hosting many customers use one machine. Either each gets a small private JVM with a strict memory cap, or several share one JVM. You get a control panel, a folder and a limit.
How a Java VPS works
A VPS is a whole virtual server. You get dedicated memory and CPU, your own Linux and root access, or a managed version where we run it. The JVM is yours to configure.
Comparison
| Shared Java hosting | Java VPS | |
|---|---|---|
| Memory | Capped, often 256 to 512 MB | Dedicated, 2 GB and up |
| Java version | What the host provides | Any version you choose |
| JVM flags | Limited | Full control |
| Frameworks | Mostly WAR on Tomcat | Tomcat, Spring Boot, WildFly, Payara, Docker |
| Database | Provided by the panel | Install your own, tuned |
| Neighbours | Can slow you down | Isolated |
| Admin work | Little | Some, unless Managed |
| Price | Lowest | Higher, predictable |
When shared is enough
- A test or demo site with almost no traffic.
- A tiny WAR that you want online for little money.
When you need a VPS
- A production application, especially with a database.
- Spring Boot, Quarkus, WildFly, Payara or Docker.
- A specific Java version or custom JVM flags.
- More than one application or background service.
- Predictable performance.
Management is the real question
The extra work of a VPS is real: updates, backups, monitoring. That is what Managed plans take over, which gives you VPS control with the effort of shared hosting.
