Deploy Spring Boot, Quarkus, Micronaut, or any Java application on a dedicated Cloud VPS. Full root access, JVM tuning, systemd service management, and 4 GB+ DDR5 RAM for comfortable JVM heap allocation.
Java applications need dedicated heap memory and JVM tuning that shared hosting and restrictive PaaS platforms cannot provide. A VPS gives you full JVM configuration control and the dedicated RAM Java needs.
-Xms and -Xmx without platform restrictions. Set your Java app's heap to exactly what it needs — 512 MB for microservices, 2 GB for enterprise apps. No PaaS memory limits or container sizing guesswork.
Compile Spring Boot or Quarkus applications to GraalVM native images for instant startup and lower memory footprint. Native image compilation requires root access and custom JDK installation — only possible on a VPS.
Run your JAR as a systemd service. Auto-start on boot, automatic restart on failure, structured logging with journalctl, and proper signal handling for graceful shutdown — production-grade Java process management.
Run PostgreSQL on the same VPS for sub-millisecond JDBC connection latency. Critical for Spring Data JPA and Hibernate applications making many database calls per request.
The optimal software stack pre-configured for this use case on a Host4Fun Cloud VPS.

Everything that makes Host4Fun Cloud VPS the ideal infrastructure for your use case.
JVM garbage collection performance is sensitive to memory bandwidth and latency. DDR5's higher bandwidth reduces GC pause times for large heap applications — critical for low-latency Spring Boot APIs and high-throughput Java services.
JVM JIT compilation is CPU-intensive. AMD Ryzen's fast cores reduce JVM warm-up time and improve steady-state throughput for JIT-compiled Java workloads. C2 compiler optimizations benefit from fast single-core performance.
Install GraalVM on your VPS and compile Quarkus or Spring Boot Native applications to native executables. Native images start in milliseconds and use 10x less memory than JVM mode — enables Java microservices on even the Starter plan.
Configure your JAR as a systemd service with proper JVM flags, environment variables, and heap settings. systemd handles auto-start on boot, automatic restart on crash (with configurable delay), and structured log output via journalctl.
Spring Data JPA / Hibernate connecting to a local PostgreSQL instance via Unix socket or loopback achieves sub-millisecond JDBC round-trip. Eliminates the 5-20ms network latency to remote cloud databases per query.
Install any JDK distribution — OpenJDK, Eclipse Temurin, GraalVM, Amazon Corretto, or Azul Zulu — with SDKMAN or apt. Switch JDK versions per application. Full freedom over Java runtime selection.
How a self-managed Host4Fun Cloud VPS compares to shared hosting and managed cloud services.
| Feature | Host4Fun Cloud VPS | Heroku (Java) | AWS Elastic Beanstalk | Azure App Service |
|---|---|---|---|---|
| JVM Heap Config | Full -Xmx control | dyno limits | ||
| GraalVM Support | ||||
| PostgreSQL Colocated | addon cost | |||
| Monthly Cost | $7–$14/mo | $7–$25+/mo | $20–$60+/mo | $15–$50+/mo |
| Dyno/Container Sleep | Always on |
Real use cases from developers, agencies, and businesses running on Host4Fun Cloud VPS.
Deploy Spring Boot REST APIs with Spring Data JPA, PostgreSQL, and Redis caching. JVM tuned for API workloads — fast startup, configured heap, and systemd auto-restart for production reliability.
Quarkus native image microservices start in milliseconds and use minimal RAM. A single VPS runs multiple Quarkus native service instances simultaneously — cost-effective microservices without Kubernetes overhead.
CS students and Java developers learning Spring Boot, Hibernate, or enterprise Java patterns need a real server to deploy to. A $7/mo VPS provides the full Java production environment for learning and portfolio projects.
Deploy Java coursework, final year projects, and algorithm implementations to a real server. Spring Boot projects running at a public HTTPS URL are significantly more impressive on a CV than localhost demos.
Spring Boot applications for internal enterprise tools, data processing, and business logic need dedicated RAM for the JVM heap. A Professional or Business VPS plan provides the memory these applications need.
Minecraft servers run on Java — typically requiring 2-4 GB RAM for smooth gameplay. A Professional plan ($14/mo, 4 GB DDR5 RAM) runs a Minecraft server for 10-30 players with dedicated resources and DDoS protection.
All plans include AMD Ryzen CPU, DDR5 RAM, NVMe SSD, 10 Gbps, DDoS protection, and dedicated IPv4.
Annual billing charged as one payment. Prices exclude taxes.
Full JVM control. Spring Boot, Quarkus, GraalVM native. PostgreSQL colocated. AMD Ryzen DDR5. From $7/mo.
