Due to the effectiveness that this approach offers, is powered by a pay-per-use approach, and a variety of sectors including finance, healthcare, and geosciences the direction of and education is toward this technology. This essay provides a summary of cloud computing. And also draws attention to the cloud computing's features, services, and deployment approach.

It signifies a departure from computing as a service provided to clients via the internet by massive data centres, or "clouds," as opposed to computing as a product that is purchased. While the IT sector is beginning to take notice of cloud computing, academic research in this area seems to be trailing behind. This report aims to provide an overview of the unexpectedly expanding advancements with inside the technical underpinnings of cloud computing and their research efforts.
