1 Scope

This Recommendation provides an approach to use cloud computing to meet existing challenges in the use
of big data. This Recommendation addresses the following subjects:
• Overview of big data;
– Introduction to big data;
– Big data ecosystem and roles;
– Relationship between cloud computing and big data;
• Cloud computing based big data system context and benefits;
• Cloud computing based big data requirements;
• Cloud computing based big data capabilities.
Note that use cases of cloud computing based big data are provided in Appendix I and II.
