Appendix III

Mapping of big data ecosystem roles into user view of ITU-T Y.3502
(This appendix does not form an integral part of this Recommendation.)

Table III.1 shows the results of mapping between the sub-role of the cloud computing reference architecture
(CCRA) user view and the performance of similar roles in the big data ecosystem. A similar sub-role with a
data supplier does not exist in CCRA. A big data service customer and a CSC may be considered to perform
similar activities. Similarly, a data broker and CSN: cloud service broker may be considered in the same
manner. If the CCRA is assumed to contain the big data service area, the activities for the CSN: cloud service
broker should be extended in the data perspective. The big data service provider is related to all sub-roles of
the CSP. This means that the big data service provider could be treated with an implanted feature or an
independent sub-role of the CSP.

Big data ecosystem Note
ITU-T Y.3502
For the cloud computing based big data environment, the new
Data supplier CSN
sub-role of the CSN for the data provider is required.
For the cloud computing based big data environment:
(option 1) the extension of the activities of the CSN: Cloud service
Data provider broker is required.
Data broker CSN (option 2) the new sub-role of the CSN for data brokerage is
required.
(option 3) adding the "brokerage" activity on the sub-role which
corresponds with the data supplier is required.
For the cloud-based big data service environment:
(option 1) using the CSC is required.
Big data service customer CSC
(option 2) the new role or sub-role of the CSC for the big data
service customer is required.
The big data service provider could be treated with an
implemented feature.
Big data service provider CSP Nevertheless, to clarify the cloud-based big data service, an
independent sub-role of the CSP for the big data service provider
is required.
