MITS5002 Cloud Computing: Issues and Challenges Research Report

This report provides an overview of the issues and challenges associated with cloud computing. It begins by defining cloud computing as an on-demand network access model offering various configurable resources, including servers, networks, applications, and storage. The report outlines the three primary service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The core of the report focuses on the challenges, including security concerns, high costs, issues with Service Level Agreements (SLAs), and the complexities of service migration. Further challenges highlighted include interoperability problems, the difficulties in developing cloud ecosystems, and the impact of proprietary cloud APIs. The report concludes with a list of relevant references to support its findings.

Cloud Computing: Issues and
Challenges
Name of the Student
Name of the University

The Cloud Computing Approach
 A model based on enabling an on-demand and convenient
networking access to different shareable pool of various
configurable resources
 Computer resources, which are employed within the cloud
computing model are servers, networks, applications, services and
storage [4]
 The cloud platforms offers a diverse range of services such as on
demand self-service, broader access to rapid elasticity, networking
and resource pooling

Service Models within the Cloud Approach
The three service models in relation to the cloud approach are:
 Software as a Service (SaaS)
 Platform as a Service (PaaS) [2]
 Infrastructure as a Service (IaaS)

Challenges faced with Cloud Approach
The challenges faced with the help of a cloud based approach are:
 The security of cloud services are considered to be of high concern
 Some cloud services have a high costing model [3]
 Issues with the Service Level Agreement (SLA)
 Deciding over which services to migrate

Challenges faced with Cloud Approach
The other challenges faced with the help of a cloud based approach
are:
 Issue based on interoperability [1]
 Hindrance based on the development of cloud ecosystems
 Different proprietary cloud APIs would make to extremely difficult
for the integration of cloud services
