Cloud Computing is all about delivering services over the Internet. It has some technical, business and economical aspects. The complexity of service provisioning has increased significantly with the increasing number of cloud services and their providers. This creates a complex situation and as a result the service provisioning techniques face hurdles. The challenge of service provisioning is to properly offer services by adjusting the complexities efficiently. There are significant works to solve the problem in different manners. But still there are some gaps that are to be noticed and bridged for future advancement of cloud technology research. In this paper an attempt has been made for analyzing the service provisioning techniques from different perspectives. The said perspectives are various techniques and methodologies, QoS parameter considered, context awareness, etc. Moreover, the role of a broker in this context is also addressed. The overall motivation is to identify the open challenges, that may provide a future research direction in context of service provisioning. © Springer Nature Singapore Pte Ltd. 2017.

Service Provisioning in Cloud: A Systematic Survey

Advances in Intelligent Systems and Computing

In cloud service domain, an acceptable standard of quality of service (QoS) must be maintained for subscribed services. The performance measurement of those cloud services is based on the satisfaction of customers with respect to the pre-defined QoS. Deviation of QoS as mentioned in SLA results dissatisfaction among users. A large numbers of business entities and consumers are involved in this service delivery process. In business environment, guaranteeing the QoS and establishing the service contracts are essential. However, for the service providers, it is challenging to maintain the QoS at run-time. Moreover, even if it is maintained, additional cost may be needed. Sometime a categorization among the consumers (premium or ordinary) is also required due to the limitation of the resources. Thus, the service management for ensuring the delivery with desired QoS at least for the premium consumers is necessary. This paper proposes a novel methodology termed as service insurances, which is incorporated into the service broker as a new module. The proposed concept is expected to ensure customer's satisfaction in context of a business application domain. © Springer India 2015.
