Cloud Computing Models: Analyzing SaaS, PaaS, and IaaS for Schools

This report provides a comprehensive comparison of Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) cloud computing models. It evaluates each model based on cost, availability, security, and administrative burden, with a focus on their applicability to school network infrastructure. The report recommends SaaS for schools due to its cost-effectiveness and ease of implementation, highlighting its benefits for student enrollment and data security. The implementation strategy includes understanding the school's needs, identifying a dedicated team, designing a scalable infrastructure, and procuring necessary components. The transition to SaaS also involves eliminating existing server infrastructure and enhancing data security through cloud service providers. The report concludes by emphasizing the importance of proper resource utilization to manage costs effectively with increased student enrollment. Desklib offers this document and many other resources for students.

Summary
Recommendation of service
The main recommendation which can be stated here relating to the need of the school and
matching the need of the student would be the Software as a service. This is due to the factor that
there are different resources which would be very much helpful from the point of view of
students. Another benefit which can be seen in the sector of implementation is the cost which is
associated with the service of SaaS (Rittinghouse & Ransome, 2016). Cost can be considered as
one of the factor which can drive the success factor of the implementation in the working of the
infrastructure of the school.
Implementation
The main sector of implementation of the solution of SaaS are as follows
 Understanding of the need of the school
 Identification of the team who would be involved in implementation/ task.
 Scalable infrastructure design.
 Finalization of the requirement of the bandwidth and facility of hosting
 Procuring of components of infrastructure.
 Deployment
 Recovery plan
Elimination of existing network
The sector which is related to the concept of lack of server infrastructure would be
removed with the implementation of the software as a service. This is due to the factor that SaaS
provides its own infrastructure which can be altered with the required infrastructure of the

9NETWORK FUNDAMENTAL
school. In most of the cases the insufficient network and the access area of the resources would
be removed due to the services being readily available from the cloud service providers (Ali,
Khan & Vasilakos, 2015). Data security can also be enhanced with the implementation of the
SaaS which is also facilitated from the end of the service providers.
Enrollment of student
The service would be working quite perfectly with the indulgence of more student. One
of the concern area in the sector of more enrollment would be requirement of the resources
which would be directly affecting the cost factor associated with the service. The wastage of
resources in such a condition can be a concern area so it can be stated that it should be taken care
that resources are utilized properly.
