Cloud computing represents a disruptive innovation in the way of provisioning and managing IT and network resources. One of the main challenge of this paradigm is the monitoring of the actual services performance offered by different Cloud service providers. For this reason, service level management plays a central role to ensure the quality of services in Public Cloud and requires a structured approach...
Service Level Management (SLM) plays a central role to ensure the quality of service (QoS) in Public Cloud environments and requires a structured E2E approach to support the migration of critical services and sensitive data. In fact, the shift of responsibility to the Cloud Service Providers (CSPs) enables the customers (CSCs) to be more focused on the business, but, at the same time, they lose direct...
Current frameworks to track the Quality of Services (QoS) are strictly related to the traditional IT approach and they are not suitable to ensure a proper control on Cloud Computing environments. This paper firstly discusses the differences of a cloud SLM versus traditional SLMs and summarizes emerging challenges in service discovery, selection and management process of SLM in cloud. Secondly it overviews...
In recent past, organizations have purchased IT equipment to be installed and directly managed within their own Data Centres. The rise of Cloud Computing generated an important shift of focus from the private boundaries of the companies to a new golden era of IT outsourcing. To analyse the quality of the services available on the market we conducted a survey based upon 58 IT professionals who have...
The key issue in cloud computing in enterprises is the management of the Quality of Service (QoS), by an appropriate SLM (Service Level Management). Cloud Service Provider are offering SLMs to their users. We think that a third party SLM can be a better way to assure a robust and equal SLM. This paper presents the elements of third party SLM, namely Cloud Service Registration Agent, Negotiation Agent,...
The paper presents a framework for quality management of Cloud Services, that aims to meet requirements of both providers and enterprises. In providers, a capacity planning phase forecasts the load in order to identify resources, while a quality aware cloud balances in real time SLM and efficiency. In enterprises, a dynamic SLA negotiation system chooses the most convenient provider for commodity...
We present a Systematic Literature Review (SLR) on Cloud Computing that selected 39 papers from first tier journals and conferences in the period 2008-2012. The selective approach captures the relevant points of view on Cloud Computing, namely the overall paradigm in terms of delivery and deployment. Afterwards, we point out the technological issues about networking and data management in Cloud Computing...
We present a Systematic Literature Review (SLR) on Cloud Computing that selected 51 papers from first tier journals and conferences in the period 2008-2012. The selective approach captures the economical perspective on Cloud Computing highlighting especially the business issues, cost/pricing models, and legal issues raised by the adoption of this new technological approach. Finally, it also spots...
