Abstract
Cloud computing is one of the most discussed topics in recent years among distributed
systems. Many Information System (IS) professionals now consider cloud technology as the
best solution to improve the growth of business in every sector. Today, there are a plethora
of cloud service architectures that are generated by prior studies. However, there is no de
facto architecture that can satisfy context-based client requirements. The provider
dependent architectures are designed in a way to suit the services and products of the
respective cloud providers. While others are targeted for specific cloud service model and
cloud deployment model.
These days, many organizations show interest to adopt cloud environment that is apt to
their local settings. To this end, organizations require cloud service architecture tailored to
their current context. On the other hand, carriers which adopt new technologies mostly with
the recommendation of providers are challenged to satisfy client requirements. The study
proposed a conceptual carrier-based cloud service architecture taking into consideration
client’s requirements and the capability of the carrier. The architecture was designed with
three major components, namely Infrastructure as a Service (IaaS), Cloud Service Broker
(CSB) and telecom capability services. The architecture has also incorporated the Service
Oriented Architecture (SOA) based Enterprise Service Bus (ESB) architecture for
dynamically configurable virtualised services.
A deployment environment is also constructed for the proposed architecture using the
analysis result of the collected data from clients and carrier cloud provider. Industry best
practice and standards have also been considered while generating the deployment
environment. Finally, an evaluation of the proposed architecture has been conducted using
experts review and it achieves a high degree of agreement among the participants.
