Cloud Computing is an emerging paradigm in the advanced network arena that facilitates the users to access shared computing resources through internet-on-demand. Cloud Computing has been widely used since it brings tremendous improvements in business. Cloud users are expected to grow exponentially in the future. In order to meet the demands of future cloud users, a full-fledged survey analyzing the various issues is the need of the hour. The different classifications presently available do not present the issues at micro levels. Amongst the various issues, the ones at design and implementation levels are of utmost importance since they directly affect the performance of the applications. Hence the cloud issues at those levels are presented in this paper from the available literature.
