Predominantly, big data as a service is a cloud-based framework, which provides end-to-end big data solutions to enterprises on their demand. It can be defined as a combined structure of data-as-a-service (DaaS), hadoop-as-a-service (HDaaS), and data analytics-as-a-service. The augmenting need for ensuring the high data quality and creating a channelized data flow in enterprises has fueled the need for technologically advanced big data solutions to gather, store, assess, visualize, and make predictions from the information gained from large data volumes. With the rising usage of cloud-based predictive analytics, the global market for big data as a service is likely to witness strong growth in the years to come.
