    01 Maven, Gradle, Spring Boot — automatic detection

    Clever Cloud automatically detects the build tool (Maven or Gradle) from your project structure. The full cycle — dependency download, compilation, packaging, startup — is handled by the platform. Supported frameworks and environments:

    • Spring Boot — executable JAR packaging, automatic detection
    • Quarkus — JVM mode and native GraalVM mode (via Docker)
    • Micronaut — fast startup, low memory footprint
    • Vert.x, Helidon, Dropwizard — supported via executable JAR
    • Java EE / Jakarta EE — deployable via Docker runtime

    JDK versions configurable via environment variable. A Procfile allows you to customize the startup command for non-standard architectures.

    02 The Java PaaS for organizations that demand reliability and compliance

    Java remains the dominant language in French IT departments, consulting firms, and large enterprises. Clever Cloud is built to meet the requirements of these organizations: high SLA, regulatory compliance, multi-team access management, production observability.

    The Premium offer guarantees a 99.99% SLA, 24/7 on-call support, and priority incident resolution in under 2 hours — for critical Java applications that cannot afford downtime. A range of enterprise services can be added, such as identity and access management (IAM) via Keycloak as a Service, enabling fine-grained permission control by environment, project, and team — without configuring a dedicated Keycloak server.

Frequently asked questions

How do I deploy a Spring Boot application on Clever Cloud?

Clever Cloud supports Maven and Gradle. Link your Git repository, configure the deployment branch, and run git push. The platform automatically detects the build tool, compiles the application, generates the executable JAR, and starts it. A Procfile allows you to customize the startup command.

Which Java versions are available?

Clever Cloud supports Java 11, 17, and 21 (LTS versions). The version is configurable via the CC_JAVA_VERSION environment variable. JVM security patches are applied automatically.

Are Quarkus and GraalVM supported?

Quarkus in JVM mode is natively supported. For native GraalVM mode (compiled binary), the application must be packaged as a Docker image and deployed via Clever Cloud’s Docker runtime.

Is Clever Cloud suitable for enterprise production Java applications?

Yes. The Premium offer provides a 99.99% SLA, 24/7 on-call support, and dedicated account management. Customers such as MAIF host their critical Java applications on Clever Cloud. The platform is ISO 27001 and HDS certified.

How do I manage multi-team access on a Java application in production?

Clever Cloud offers native RBAC (Role-Based Access Control) configurable by organization, project, and environment. For enterprise SSO requirements (LDAP, SAML, OIDC), Keycloak as a Service is available directly from the marketplace.
