Reliability of cloud computing in Quantum Chemistry calculations

Cloud computing is an emerging technology to the scientific community in variety of disciplines. Especially, in chemistry related fields like bio-informatics, pharmaceutical chemistry and even in chemical industry, its role is significant at present. The research in theoretical chemistry such as Quantum Chemistry, Molecular Modeling, Molecular Dynamics, Theoretical Chemical Kinetics and Chem-informatics, requires extensive computational cost which have been considerably reduced because of this new technology. However, the extent of effectiveness of cloud computing in such studies, if the access is from commercial providers would be unreliable. Here in the advantages of cloud computing in theoretical chemistry, giving emphasis to quantum chemistry calculations with respect to cost, security and accessibility have been reported. The comparison is made with some leading commercial cloud providers and private clouds.
