In digital century cloud computing is most use and fastest growing platform for making resources available to the users. Data can be available to the user easily with their credential like name password etc users have to memorize these things. But for programmer/developer there is much more to do. Cloud computing is based on internet there are large number of servers where user can access and store data. In terms of cloud computing the background network is known as DCN (Data Center Network). In this paper we have explain Skip List Topology because this topology in the account as the size of list is dynamic and how we can reduce the data traverse time and traffic of network. It is very easy to insert and search data in the list. It is apparent that Skip List is better in term of efficiency then B-tree where both are based on DCN.
