Cloud computing, an amalgam of existing technologies ranging from distributed computing to clustercomputing, to grid computing, to virtualization (which forms the foundation of these technologies) has changed the wayorganizations use Information and Communication Technology (ICT). Instead of acquiring resources for on-premise ICTdepartments, these resources are provisioned as service. It usually involves a pool of resources that multiple users cantap into and make use of (in parallel) whenever there is need to. These resources are also provisioned dynamically andare scaled up/down depending on demand. In addition, like any other utility, payment is done on a pay-per-use modelthus reducing the huge initial cost of acquiring on-premise IT infrastructure. Since inception, there has been a steadyincrease in the number of users migrating to the clouds. Based on this increase, there is need to optimally allocate cloudresources so as to ensure that users perceived satisfaction is guaranteed. This work is an exposé on the challenges ofresource allocation in cloud computing and works done in order to surmount these challenges. The work further goes onto juxtapose the various resource allocation strategies in order to identify their strengths and weakness based on howwell they avoid situations such as resource under provisioning, over provisioning, contention, fragmentation andscarcity.
