Cloud computing provides physical and logical computation resource on demand for the set of service. Cloud environment reduce the infrastructure cost and easy to use without any extra burden. Cloud storage an access raised the several security issues like data privacy, access control, authentication, virtual machine security, web security etc., In one side hackers, breaches, cloud security issues and threats get expanded. But in another side many technologies are keep increased to secure cloud data. Technology may be cryptographic technique, anonymization technique, machine learning technique etc., In this paper we analyse cloud computing basics, models, machine learning technique and some security solution through machine learning technique such as support vector machine (SVM), K-Nearest Neighbour (KNN), Decision tree and Naïve Bayes classifier technique.
