2 Cloud Computing management

The data consumer side-related operations can be described as the following procedure.

1) The data consumer requests a data operation from the IDPEP.
2) The IDPEP requests a data policy decision from the IDPDP.
3) The IDPDP requests the specific data policy from the IDPIP.
4) The IDPIP returns the requested data policy to the IDPDP.
5) The IDPDP returns the decision result to the IDPEP based on the collected available resources.
6) The IDPEP performs the data operation based on the data policies.

7) The processed data result is returned to the IDPEP.
8) The IDPEP provides the final results of the data operation to the data consumer.

6.4 Relationship with cloud computing reference architecture
[ITU-T Y.3502] specifies two functional components to support inter-cloud computing, also known as peer
service integration (see clause 9.2.5.1.4 of [ITU-T Y.3502]) and peer service management (see clause 9.2.5.3.9
of [ITU-T Y.3502]). [ITU-T Y.3516] identifies an inter-cloud specific extension to the functional components of
[ITU-T Y.3502] that are part of integration, security systems, operational support system (OSS) and business
support system (BSS) (see clause 8 of [ITU-T Y.3516]). This Recommendation is based on the functions
defined in [ITU-T Y.3502] and [ITU-T Y.3516] on inter-cloud computing and does not define or extend any
new functions. This Recommendation focuses on data management in the inter-cloud environment based on
the establishment of a relationship (pattern) among multiple peer CSPs, including peering, federation and
intermediary, which are defined in [ITU-T Y.3511].

7 Functional requirements for inter-cloud data policy
This clause provides the functional requirements for inter-cloud data policy derived from the use cases
described in Appendix I.

7.1 Data policy language

It is recommended that the CSP support inter-cloud data policy to satisfy data processing and usage.
It is recommended that the CSP support the DPL to annotate (tagging) cloud workloads.
It is recommended that the CSP support inter-cloud data annotation (tagging) in order to realize the CSC
request.

7.2 Inter-cloud data policy administration point

It is recommended that the CSP support the IDPAP to administer data policies in inter-cloud.

7.3 Inter-cloud data policy information point
It is recommended that the CSP support the IDPIP to store the data policy provided by the CSC in inter-cloud.

7.4 Inter-cloud data policy decision point

It is recommended that the CSP support the IDPDP to enforce the data policy on the basis of information
collected by the IDPEP about data processing and usage among peer CSPs in inter-cloud.

7.5 Inter-cloud data policy enforcement point
It is recommended that the CSP support the IDPEP to implement the data policy decision of the IDPDP in the
inter-cloud environment.
It is recommended that the CSP support the IDPEP to collect information about data processing and usage
among peer CSPs in inter-cloud and deliver this information to the IDPDP.
