# Java SDKs

Use the IONOS Cloud Java SDK to integrate IONOS Cloud into JVM services and enterprise applications.

### When to use the Java SDK

* JVM microservices that manage IONOS Cloud resources.
* Platform tooling and internal portals.
* Integrations in larger Java ecosystems.

### Prerequisites

* An IONOS Cloud account.
* API access for your tenant.

### Authentication

Use the same credentials you use for the IONOS Cloud API.

Keep credentials out of code and config files.

### Common workflows

* Create and manage infrastructure resources.
* Enforce guardrails via custom logic.
* Integrate provisioning into existing systems.

### Troubleshooting

* Validate your credentials and permissions.
* Confirm outbound HTTPS access to the API endpoints.

### Next steps

* Use the REST API if you need full request control.
* Use an IaC tool for standardized provisioning across teams.
