wherein the first component comprises the compute component, and the second component comprises the storage component;

wherein the first resource is the compute resource, and the second resource is the storage resource; and

wherein the causing the co-location includes allocating a new compute resource on the at least one host on the basis of the inquiry response including the host address for identifying the at least one host hosting the storage resource.

8. A component entity for controlling at least one of a first resource and a second resource in a system including the component entity, a further component entity, and at least one host in a cloud environment; the at least one host hosting the second resource; the first resource being managed by the component entity; the second resource being managed by the further component entity; wherein amongst the component entity and the further component entity one comprises a compute component entity and the other comprises a storage component entity; and wherein amongst the first resource and the second resource one is a compute resource and the other is a storage resource; the component entity comprising:

processing circuitry; and

memory containing instructions executable by the processing circuitry whereby the component entity is operative to:

send an inquiry request to the further component entity, the inquiry request including an inquiry relating to the second resource;

receive an inquiry response from the further component entity, the inquiry response including a host address for identifying the at least one host; and

locate the first resource and the second resource on a single host based on the inquiry response, the single host being one amongst the at least one host and a further host hosting the first resource.

9. The component entity of claim 8 , wherein the instructions are such that the component entity is operative to send the inquiry request in response to a request to deploy or reconfigure at least one of the first resource and the second resource.

10. The component entity of claim 8 , wherein the instructions are such that the component entity is operative to establish a physical correlation between the first resource and the second resource.

11. The component entity of claim 8 :

wherein the component entity comprises the storage component, and the further component entity comprises the compute component;

wherein the first resource is the storage resource, and the second resource is the compute resource; and

wherein the instructions are such that the component entity is operative to allocate a new storage resource on the at least one host based on the inquiry response including the host address for identifying the at least one host hosting the compute resource.

12. The component entity of claim 8 , wherein the instructions are such that the component entity is operative to reconfigure at least one of the first resource and the second resource so that both of the first resource and the second resource are hosted on the single host.

13. The component entity of claim 8 :

wherein the component entity comprises the compute component, and the further component entity comprises the storage component;

wherein the first resource is the compute resource, and the second resource is the storage resource; and

wherein the instructions are such that the component entity is operative to allocate a new compute resource on the at least one host based on the inquiry response including the host address for identifying the at least one host hosting the storage resource.

14. A system for controlling a first resource and a second resource, the system comprising:

a first component, a second component, and at least one host in a cloud environment, wherein the at least one host is composed of a hardware processor and a hardware memory; the at least one host hosting the second resource;

wherein the first component manages the first resource;

wherein the second component manages the second resource;

wherein amongst the first component and the second component one is a compute component and the other is a storage component;

wherein amongst the first resource and the second resource one is a compute resource and the other is a storage resource;

wherein the first component is configured to send an inquiry request to the second component, the inquiry request including an inquiry relating to the second resource;

wherein the second component is configured to send an inquiry response to the first component, the inquiry response including a host address for identifying the at least one host; and

wherein at least one of the first component and the second component is configured to locate the first resource and, respectively, the second resource on a single host based on the inquiry response, the single host being one amongst the at least one host and a further host hosting the first resource.

15. A non-transitory computer readable recording medium storing a computer program product for controlling a first resource and a second resource in a system including a first component, a second component, and at least one host in a cloud environment;

the at least one host hosting the second resource; the first resource being managed by the first component; the second resource being managed by the second component; wherein amongst the first component and the second component one comprises a compute component and the other comprises a storage component; and wherein amongst the first resource and the second resource one is a compute resource and the other is a storage resource, the computer program product comprising software instructions which, when run on processing circuitry of a component entity, cause the component entity to:
