This review would provide clarity on the current trends in task scheduling techniques based on convergence issues and the problem solved. This allows instructors to more easily see when students are stuck or heading in the wrong direction. Cloud computing offers a range of potential cyber security benefits for cloud consumers to leverage, providing access to advanced security technologies, shared responsibilities, fine-grained access management, comprehensive monitoring and highly redundant geographically dispersed cloud services. This is not just a problem-the shift from old software models to the internet has achieved constant speed over the past eleven years.
