# Deploy FastAPI on Cloud Providers { #deploy-fastapi-on-cloud-providers }

You can use virtually **any cloud provider** to deploy your FastAPI application.

In most of the cases, the main cloud providers have guides to deploy FastAPI with them.

## FastAPI Cloud { #fastapi-cloud }

**<a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>** is built by the same author and team behind **FastAPI**.

        // Try providers in order of preference
        List<RdmaProvider> providers = Arrays.asList(new DisniRdmaProvider(), // InfiniBand/RoCE - highest performance
                new TcpRdmaProvider() // TCP fallback - always available
        );

        for (RdmaProvider provider : providers) {
            if (provider.isAvailable()) {
                log.info("Selected RDMA provider: {}", provider.getProviderName());

    public void testCreateProviderAuto() {
        RdmaProvider provider = RdmaProviderFactory.createProvider("auto");
        assertNotNull(provider, "Auto provider selection should return a provider");
        assertTrue(provider.isAvailable(), "Returned provider should be available");
    }

    @Test
    public void testCreateProviderTcp() {
        RdmaProvider provider = RdmaProviderFactory.createProvider("tcp");

  because they are specific for each packaging:

  Versions of the plugins are shared in a few constants:

# Развертывание FastAPI у облачных провайдеров { #deploy-fastapi-on-cloud-providers }

Вы можете использовать практически любого облачного провайдера, чтобы развернуть свое приложение на FastAPI.

В большинстве случаев у основных облачных провайдеров есть руководства по развертыванию FastAPI на их платформе.
