Big data as a service (BDaaS) is the delivery of statistical analysis tools or information by an outside provider that helps organizations understand and use insights gained from large information sets in order to gain a competitive advantage.
Given the immense amount of unstructured data generated on a regular basis, big data as a service is intended to free up organizational resources by taking advantage of the predictive analytics skills of an outside provider to manage and assess large data sets, rather than hiring in-house staff for those functions. Big data as a service can take the form of software that assists with data processing or a contract for the services of a team of data scientists.
BDaaS is a form of managed services, similar to Software as a Service or Infrastructure as a Service. Big data as a service often relies upon cloud storage to preserve continual data access for the organization that owns the information as well as the provider working with it.
