Questions top executives should ask about cloud computing
... Loud computing has been defined by national institute of standards and technology (NIST) as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (software, hardware and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction [2]. It is an emerging and fast growing computing paradigm that uses internet technologies to enable and facilitate the provisioning of service-oriented, adaptable and scalable IT-based capabilities to external suscribers or clients [1], [3]. It has evolved primarily three widely referenced and adopted service models. ...
... Since the advent of Information Technology (IT), organizations and corporations globally have experienced enhancement and improvement in their various organizational processes and operations. The various health organizations are no exceptions [1]. Currently, the healthcare industry is faced with growing regulatory pressures coupled with high rising economic demands that pose a dire and urgent need for a change and improvement in its Information Technology (IT) infrastruc- ture [9], [11]. ...
... This is potentially driving the imminent need for the adoption and acceptance of cloud computing , especially going by the various investments in the health industry by the governments in Sub-Saharan Africa (SSA) towards achieving the United Nations Millennium Development Goal (UN MDG) [10], [11]. It is a fast evolving computing paradigm that has the promising potential & inherent benefits to deliver this needed im- provement [1]. Top on the priority list of the health care industry are: improved quality of health care, increasing access, reducing cost, and ensuring health data privacy and security [1] . ...
The major concerns for most cloud implementers particularly in the health care industry have remained data security and privacy. A prominent and major threat that constitutes a hurdle for practitioners within the health industry from exploiting and benefiting from the gains of cloud computing is the fear of theft of patients health data in the cloud. Investigations and surveys have revealed that most practitioners in the health care industry are concerned about the risk of health data mix-up amongst the various cloud providers, hacking to comprise the cloud platform and theft of vital patients' health data. An overview of the diverse issues relating to health data privacy and overall security in the cloud are presented in this technical report. Based on identifed secure access requirements, an encryption-based eHR security model for securing and enforcing authorised access to electronic health data (records), eHR is also presented. It highlights three core functionalities for managing issues relating to health data privacy and security of eHR in health care cloud.
At present, the whole world is transitioning to the fourth industrial revolution, or Industry 4.0, representing the transition to digital, fully automated environments, and cyber-physical systems. Industry 4.0 comprises many different technologies and innovations, which are being implemented in many different sectors. In this review, we focus on the healthcare or medical domain, where healthcare is being revolutionized. The whole ecosystem is moving towards Healthcare 4.0, through the application of Industry 4.0 methodologies. Many technical and innovative approaches have had an impact on moving the sector towards the 4.0 paradigm. We focus on such technologies, including Internet of Things, Big Data Analytics, blockchain, Cloud Computing, and Artificial Intelligence, implemented in Healthcare 4.0. In this review, we analyze and identify how their applications function, the currently available state-of-the-art technologies, solutions to current challenges, and innovative start-ups that have impacted healthcare, with regards to the Industry 4.0 paradigm.
