Greenhouse Gases (GHGs) emission is the principal cause of global warming. In order to regulate the emissions of these gases, the emissions need to be assessed and quantified. Carbon footprint is the evaluation of human activities that lead to GHGs emissions. The Covenant University Electricity Network during periods when utility supply fail runs on diesel powered generators located at different centers within the campus. These generators emit carbon-based compounds into the environment. Assessing the quantity of carbon dioxide which is the principal GHGs emitted per year gives 33.14-tonnes. Analysis of the load profiles in the centers showed that all the eight generators are not supposed to be running simultaneously as it is now. This study developed a new network model where all the generators were integrated into a DC microgrid that ensured resource sharing. The model was simulated using energy management and optimization techniques resulting in reduced micro-generators engagement, Green House Gases emission and fuel consumption. Consequently, carbon dioxide emitted per year dropped to 18.44-tonnes from 33.14-tonnes. The developed model improved the carbon footprint of the campus by as much as 44.3%.

Cloud service providers centralize all servers, networks, and applications to allow their users' access at any time and from any location. Cloud computing uses already existing resources like server, CPU and storage memory but runs on a new technology known as virtualization. The core idea of virtualization is to create several virtual versions of one single computing device or resource. This enables many user operating systems to work on such a single underlying piece of device. Network bandwidth is one of the critical resources in a cloud environment. Bandwidth management involves the use of techniques, technologies, tools, and policies to help avoid network congestion and ensure optimal use of the subscribed bandwidth resources while also being a bedrock of any subscription-based access network. Bandwidth management is being utilized by organizations to allow them to efficiently utilize their subscribed bandwidth resources. Bandwidth management deals with the measurement and control of packets or traffic on a network link in order to refrain from overburdening or overloading the link which can lead to poor performance and network congestion. In this paper, the highest development with respect to virtualization in cloud computing is presented. This study review papers available on cloud computing and relevant published literature in multiple areas like conferences, journals etc. This paper examined present mechanisms that enable cloud service providers to distribute bandwidth more effectively. This paper is therefore a study of virtualization in cloud computing, and the identification of bandwidth management mechanisms in the cloud environment. This will benefit forthcoming cloud providers and even cloud users..

Virtual machines are the core of cloud computing that runs as independent machine grouped into different networks within the hypervisor. Practically done by deployment of clouds computing hosts enterprise servers in virtual machines on an array of high-end servers. Managing cloud resources has to do with controlling and limiting access to the pool of available resources. This brings about the conception of an agreement between the resource services cloud providers and the customers otherwise known as Service Level Agreement, in other to restrict access to provisioned resources. Resource provisioning is a flexible on-demand pay-as-you-go package that is negotiated; and signed based on SLAs between customers and cloud providers. SLAs enable cloud providers to evade costly SLA consequences payable when there are violations, optimizing the performance of customers' applications and professionally manage resources to reduce cost. These documents are the agreements called Service Level Agreements (SLAs). SLAs outline the expectations which are: terms, conditions, and services of the clients from their service providers regarding availability, redundancy, uptime, cost, and penalties in cases of violations. These ensure clients' confidence in the services offered. Managing resource is an ongoing major issue in cloud computing. Considering the limitation of resources, it poses a challenge for cloud service providers to make provision for all resources as needed. This paper seeks a solution to problems that relates to the present trends and developments of what cloud Service Level Agreements are and it ensures so by reviewing current literature. Thus, this research is a study of cloud Service Level Agreements, cloud resource management and their challenges. This paper has made provision to act as guidance for future research and it is anticipated to be beneficiary to potential cloud end users and cloud service providers.
