An activity is a set of tasks that accomplish a goal.

According to ISO/IEC 17789, the three main groups of cloud service activities are:

  • Activities that use services
  • Activities that provide services

ISO/IEC 17789 defines three major roles that perform groups of activities in cloud computing. The activity roles are:
