Cloud computing is turning into a notable catchphrase lately. It is a developing and quickly developing registering innovation which uses the web and remote servers to oversee information and applications. It is ceaselessly developing and demonstrating reliable development in the field of processing. It is applied in a few fields alongside huge information examination, the web of things and relentless things are finished with these ongoing advancements. The significant purpose of this paper is to concentrate the absolute most recent methods in distributed computing, which will be helpful for productive information access and information calculation. This paper examines about the vitality proficient Ant Colony System (ACS) calculation utilized for Virtual Machine Placement (VMP) in Cloud, self-sorting out Cloud Radio Access Network (C-RAN) that powerfully adjust to differing system limit requests, Field Programmable Gate Arrays (FPGA) quickening agent planning used to limit the make-range of a given cluster of FPGA demands where make-length is an ideal opportunity to finish all activity demands in a solitary clump, and Intelligent Health vessel ABC-DE which is an electrocardiogram figuring administration where ABC-DE is the shortened form of Artificial Intelligence, Big Data, Cloud Computing - Detecting ECG (Electro Cardio Gram). These are a portion of the ongoing calculations and procedures utilized for the proficient information access and information calculation
