 #### Helmholtz Cloud Service Portfolio
 The Helmholtz Cloud will appear as a federated cloud. All services are hosted by one of the 19 Helmholtz centers. There will be some services that are available for all Helmholtz employees. But in many cases, it will be unavoidable to sign an additional agreement between the providing center and the using organization. So, the services you can use will depend if the agreements between your organization and the providing Helmholtz center exists.
