Big data - Concept and application for telecommunications 1

1 Scope

This Recommendation provides an overview of the big data as a service (BDaaS) functional architecture and
defines the BDaaS functional architecture and cross-cutting aspects by specifying the functional components
for the support of BDaaS.

3 Definitions

3.1 Terms defined elsewhere

This Recommendation uses the following terms defined elsewhere:
3.1.1 activity [ITU-T Y.3502]: A specified pursuit or set of tasks.

3.1.2 big data [ITU-T Y.3600]: A paradigm for enabling the collection, storage, management, analysis and
visualization, potentially under real-time constraints, of extensive datasets with heterogeneous
characteristics.
NOTE – Examples of datasets characteristics include high-volume, high-velocity, high-variety, etc.

3.1.3 big data as a service (BDaaS) [ITU-T Y.3600]: A cloud service category in which the capabilities
provided to the cloud service customer are the ability to collect, store, analyse, visualize and manage data
using big data.
3.1.4 cloud computing [b-ITU-T Y.3500]: Paradigm for enabling network access to a scalable and elastic
pool of shareable physical or virtual resources with self-service provisioning and administration on-demand.
NOTE – Examples of resources include servers, operating systems, networks, software, applications, and
storage equipment.
3.1.5 cloud service [b-ITU-T Y.3500]: One or more capabilities offered via cloud computing invoked using
a defined interface.

3.1.6 cloud service customer (CSC) [b-ITU-T Y.3500]: Party which is in a business relationship for the
purpose of using cloud services.

3.1.7 cloud service partner (CSN) [b-ITU-T Y.3500]: Party which is engaged in support of, or auxiliary to,
activities of either the cloud service provider or the cloud service customer, or both.

3.1.8 cloud service provider (CSP) [b-ITU-T Y.3500]: Party which makes cloud services available.
3.1.9 functional component [ITU-T Y.3502]: A functional building block needed to engage in an activity,
backed by an implementation.
3.1.10 metadata [b-ISO/IEC 2382]: Data about data or data elements, possibly including their data
descriptions, and data about data ownership, access paths, access rights and data volatility.
