The study examined the forms and models of cloud computing technology adopted in the selected institutions from four states in Southwestern Nigeria. The three purposively selected institutions were Federal, State and Private owned making twelve institutions. However, the administered questionnaire was filled in by the ten (10) IT personnel, ten (10) lecturers and five (5) students from each of the selected institutions making 300 respondents. The questionnaire elicited information on the forms and models of cloud computing technology adopted and the extent of use of the adopted cloud computing technologies in the selected institutions. Secondary data were obtained from relevant literature. Data collected were analysed with descriptive and inferential statistics. The study concludes that the forms of cloud computing technology adopted by the selected institutions in Southwestern Nigeria are infrastructure-as-a-service (IaaS), software-as-a-service (SaaS) and platform-as-a-service (PaaS) while software-as-a-service (SaaS) is often used by the institutions. Also, the models of adopted cloud computing technology are private, public, hybrid and community cloud computing by the selected institutions in Southwestern Nigeria. The adopted forms and models of cloud computing technology are used for different business functions such as payroll, procurement, human resources, accounting and finance, CRM, application development, and project management.

Cloud computing refers to a model for accessing computing resource like networks, servers, storage, applications, and services remotely. Cloud computing offers these resources as a service, namely infrastructure-as-a-service, platform-as-a-service, and software-as-a-service. To use these services, two roles involved: the cloud provider offers the service and the cloud customer consumes the service. These resources are efficiently shared and utilized by customers and it is called workload. The requirement of workload depends on customer demands that vary from higher to lower. Based on the customer demand, cloud provider makes the resource available efficiently. In the context of cloud, the workload is based on web-based service or jobs processed in batch mode. The arrival process of jobs in the cloud is not often deterministic. The irregular increase or decrease in workload has a vital impact on resource provision. Monitoring the resources helps in measuring the performance of the cloud so that the resource can be provisioned to customers efficiently.

Cloud computing is gradually increasing its popularity in enterprise-wide organizations. Information technology organizations e.g., IBM, Microsoft, and Amazon have already shifted towards Cloud computing. Cloud-based offerings such as Software as a Service, Platform as a Service and Infrastructure as a Service (IAAS) are the most famous offerings. Most of the existing enterprise applications are deployed using an on-premise model. Organizations are looking for Cloud based offerings to deploy or upgrade their existing applications. SAP, Microsoft Dynamics, and Oracle are the most famous ERP or CRM application OEMs. These enterprise applications generate lots of data are hosted in an organization or on client data centers. Moving data from one data center to the Cloud is always a challenging tasks which cost a lot and takes much effort. This study proposes an efficient approach to optimize cost for data migration in cloud computing. This study also proposes the approach to optimize cost for data collection from multiple locations which can be processed centrally and then migrate to Cloud Computing.

AbstractNowadays schools own computer labs and laptop carts developed to be shared among a large quantity of students and this task requires buying desktop computers and other necessary inventory that create opportunities for them to achieve skills in basic computer programming, internet browsing, etc. Unfortunately, schools cannot afford expensive desktop computers, which require maintaining services and software updates and Chromebook become a real life solution for that issue, because it does not require any expensive maintaining operations and it uses Cloud- Based System for all data that students have. Keywords: Cloud computing; Technology Education; Non-Cloud-Based Computer Systems; Cloud- Based Computer;

Cloud computing makes use of many standard technologies in surprisingly novel ways. It leaves many people bewildered, even confused, especially as it is an area of computing that is undergoing rapid change in terms of a diversification of available services and the growth in underlying contingent technologies. This article shows how the cloud has changed the user experience and goes on to discuss the definition of cloud computing most commonly used. It describes the three service models of Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) and then discusses the four deployment models of private cloud, public cloud, hybrid cloud and community cloud. It concludes with how the cloud impacts security and how most organizations will likely make use of multiple cloud providers. This article introduces key concepts and characteristics of cloud computing, in this way covering in broad terms what it is and how it essentially works.

Cloud computing suggests that the applications conveyed as services over the internet and frameworks programming in the server that give various services and offers in “pay as you go” trend which means pay only for what you use. The information and services are managed as software as a service (SaaS). Some sellers utilize terms, for example, IaaS (infrastructure as a service) and PaaS (platform as a service). The purpose of cloud computing is quickly expanding in everyday life. Today the use of cloud computing is widespread to the point that it is being utilized even in the medicinal services industry. As the development of cloud computing in healthcare is happening at a fast rate, we can expect a noteworthy piece of the healthcare administrations to move onto the Cloud and along these lines more focus is laid on giving cost-effective and efficient services to the general population all around the world. Cloud these days are turning into the new building pieces of significant organizations spread the world over. They offer assistance in servicing to offer different frameworks. Cloud computing has enhanced its technique and technologies in a better way to provide better services. Existing e-healthcare has many difficulties from advancement to usage. In this chapter, the authors discuss how cloud computing is utilized and the services provided by the Cloud and their models and its infrastructure.
