High-performance Java

Java runs best on Oracle Cloud Infrastructure (OCI). Oracle continues to innovate for the cloud with the GraalVM high performance JDK to accelerate modern microservices-based application performance. Generate more efficient code that starts up faster and uses fewer system resources. Get an additional performance boost from patented optimizations that come with Oracle GraalVM—at no additional cost.

It took 30 years to make a Java developer conference this good
JavaOne 2025 - March 18–20, 2025

JavaOne 2025 marks the return of Oracle’s premier Java developer conference—just in time for
Java’s 30th anniversary. Join a who’s who of Java luminaries as we celebrate with three days of
learning, laughter, and the launch of Java 24.

Deploy Java on OCI benefits

Lower operations cost

Save money by executing the same workloads with fewer compute resources. With Oracle GraalVM, you can dramatically improve Java application performance resulting in faster startup time and lower memory consumption. Running Java on the OCI platform delivers an additional 3X better compute price-performance and 20X better IOPS than AWS base for half the price.

High-performance Java on OCI at no additional cost

Oracle GraalVM is offered at no charge when running Java and JVM-based applications on OCI. Java is the #1 language for cloud native development. It supports multi-language interoperability with no performance penalty.

Modernize existing Java applications—or build new apps

Build new, high-performance Java microservices that start up almost instantly. Native executables use a smaller memory footprint ideal for running in containers with Kubernetes. With an ecosystem of tools, Oracle GraalVM is the preferred way to build with Spring Boot, Micronaut, Helidon, or Quarkus. Optimize existing Java applications on OCI with better performance, stability, and support—backed by the Java experts.

OCI is the best platform for running Java

Application modernization requires the right tools and the right runtime environment to enable better efficiency, performance, and cost savings at scale. OCI users enjoy the benefits from these solutions at no additional cost: Oracle GraalVM, Java Management Service, Oracle Java SE Subscription Enterprise Performance Pack, and Oracle Support.

Oracle GraalVM

Build more efficient code that starts almost instantly or accelerate the performance of your existing Java applications.

GraalVM Native Image ahead-of-time (AOT) compiles Java code, enabling microservices to start 100X faster.
Popular frameworks, such as Helidon, Micronaut, Quarkus, and Spring Boot, chose GraalVM to build and run microservices to take advantage of instantaneous start up, small memory footprint, and peak performance with zero warm-up.
GraalVM high performance just-in-time (JIT) compiler accelerates existing Java performance up to 25%.
GraalVM polyglot support provides high performance runtime support of application written in different languages. It improves productivity by letting developers use the right language and library for a given task.

Oracle Java Management Service

Organizations often have numerous distinct versions of the Java platform installed across desktops, servers, and the cloud. Keeping outdated versions of Java in your environments can present significant security risks. The Java Management Service (JMS) is a free OCI service that monitors Java deployments in the cloud and on-premises. With JMS, you can:

Centralized Management: A single pane of glass to monitor and manage Java workloads across your enterprise.
Security Risk Mitigation: Identify outdated Java versions to minimize security vulnerabilities.
Advanced Features: Access additional functionalities, including Java Migration Analysis, Performance Analysis, vulnerability detection in Java libraries, and more.
