Two popular technologies, Big Data and Cloud Computing, have become the focus of IT professionals' worries. There is a massive influx of information from a variety of sources every day. The sheer volume of this data makes it unmanageable by standard data processing methods. This data is not only massive, but also dynamic and extremely varied. The term "Big Data" refers to the practice of storing, processing, and analysing massive datasets. The focus of cloud computing, on the other hand, is on providing the underlying infrastructure to make such operations both feasible and efficient. The potential of Big Data is being explored by many different fields, including small and major organisations, healthcare, and education.
