The Cloud computing architecture consists of front-end
platforms called clients which could be servers, (fat, thick,
thin, or zero) clients, tablets and mobile devices. The client
platform interacts with the cloud data store through an
application middleware, web browser, or virtual session. The
three main categories of cloud computing are: private clouds,
public clouds and hybrid clouds. Private clouds are used
exclusively by a single organization comprising multiple
consumers. Public clouds are open access clouds that the
general public can access. Hybrid clouds are infrastructures
that combine two or more cloud deployment models (e.g.
private and public). Some studies that have addressed the
problems and implementation techniques for cloud based
systems include: Rolim et al [8] and Saif et al [9].
According to the mobile cloud computing forum, mobile cloud
computing can be described as an infrastructure where both
the data storage and data processing happen outside of the
mobile device [2]. That is a combination of mobile web and
Cloud computing. Mobile devices have nowadays become one
of the most common means by which users can access
applications and services on the Internet. With mobile cloud
computing users with mobile devices do not need a powerful
configuration in terms of CPU speed and memory capacity
because all the complicated computing modules can be
processed in the cloud. Advantages of mobile cloud computing Figure 1: Mobile cloud computing architecture [2]

the Nigerian government to join hands with the stakeholders and
ensure that Nigeria has a viable eHealth strategy/policy in place.

In this study, a framework for a cloud-based health monitoring
system has been proposed. This framework provides a method for
