{: #hosting}
If you have an existing app, you can host it on {{site.data.keyword.Bluemix}} with all the infrastructure or platform services you need. You can also migrate your app to {{site.data.keyword.Bluemix_notm}} incrementally instead of shifting your app to the cloud environment all at once.
{: #migrating}
If you need your app to access your on-premises data or services, you can use {{site.data.keyword.SecureGatewayfull}} to establish a secured tunnel between an {{site.data.keyword.Bluemix_notm}} organization and your enterprise backend network. For details, see Reaching enterprise backend with {{site.data.keyword.Bluemix_notm}} Secure Gateway via console{: new_window} 
.
If you need help with your migration, IBM Cloud Migration Services{: new_window} are available.
{: #ht_hostapp}
In the {{site.data.keyword.Bluemix_notm}} catalog{: new_window} , you can choose a managed environment like Kubernetes or Cloud Foundry, or can you host your app directly on a bare metal or virtual server.
On a virtual deployment, most of your app's operations are managed by {{site.data.keyword.Bluemix_notm}}. A virtual deployment is best if your workload is spread out across geographic regions and you want to use an {{site.data.keyword.Bluemix_notm}} hypervisor to manage your deployments. A bare metal deployment is best if you need direct access to a dedicated physical server for higher performance.
You also have many options for:
- Selecting the type of storage{: new_window}
that's right for you from block storage, file storage, or Object Storage. - Selecting the type of network{: new_window} you need.
- Selecting a containerization{: new_window} service to take advantage of {{site.data.keyword.Bluemix_notm}} Kubernetes technology.
