Cloud standards are uniquely suited to crossing boundaries that occur in hybrid cloud deployments. This column presents several new efforts in this area and discusses their history and current state, along with related software projects.
This column completes a two-part exploration into features of application programming interfaces (APIs) that are useful in clouds. The discussion contrasts APIs with other types of interfaces and describes variations on protocols and calling methods, giving examples from physical hardware control to illustrate important features of cloud API design.
The Open Virtualization Format (OVF) is a software packaging standard designed to support the portability and deployment of applications in different virtualization platforms. Ease interoperability and portability among cloud providers is of paramount importance to mitigate vendor lock-in and fostering cooperation among different cloud technologies. To this end, the researcher community is spending...
Cloud computing is a revolutionary paradigm that allows to acquire infinite resources on demand and pay only for the actual use. Together with novel software development methodologies, such as Agile and DevOps, the cloud can really help companies in responding to market demand for continuous delivering innovative services, enabling the shift from a silo based release process, where customers, developers...
For some years now, the concept of Cloud Computing (CC) is presented as the new revolution of information technology. It presents not only a technical innovation for better IT system flexibility, improvement of working methods and cost control, but also a new economic model, built around the concept of IT Services that are identifiable, classifiable and countable for end users, who can benefit by...
This case study showcases the innovative use of ICT within Mauritius. It is shown how the implementation of commercial-off-the-shelf application software has enabled Mauritian Government organisations to adopt global best practice. The paper focusses on revenue management, with particular reference to Mauritius Revenue Authority (MRA) and Central Electricity Board (CEB), and how the achievements at...
Cloud computing (the delivery of computing as services rather than products) creates new challenges with respect to openness. Existing approaches such as open source licensing of software products have proven inadequate in a service-oriented world; attempts to address the limitations by closing the “service provider loophole” have failed to gain traction. Similarly, multiple providers are yet to fully...
Software as a Service (SaaS) is a software delivery model in which software resources are accessed remotely by users. Enterprises find SaaS attractive because of its low cost. SaaS requires sharing of application servers among multiple tenants for low operational costs. Besides the sharing of application servers, customizations are needed to meet requirements of each tenant. Supporting various levels...
Obtaining cloud computing services can be viewed as a form of outsourcing, and as such it shares the essential risk profile of all outsourcing contracts concerning opportunistic behavior, shirking, poaching, and opportunistic renegotiation. Developing cloud computing is also an advanced technological development effort, and as such it shares all of the risks of large and uncertain development efforts...
Nowadays technologies, frameworks and architectures are forced to be service driven, platform independent, reliable and scalable. Application markets, Service Oriented Architectures and Cloud Computing are currently in focus of the new upcoming business models. Based on an analysis of service life cycle management and composition standards the following article illustrates an architecture for a service...
Although event recording on a computer system (also known as logging) is of utmost importance for reconstructing and detecting security relevant events, currently no adequate and sophisticated solution for complex environments, such as Grid and Cloud Computing, exist. Current LOG file formats lack of several important factors, hindering automatic evaluation needed for distributed systems to comply...
Software-as-a-Service (SaaS) is an emerging software application delivery model. It has gained an increasing momentum, and it is being adopted at a very fast pace. However, the integration of SaaS applications with enterprise on-premise applications has become a major factor for the success of its adoption. There is a critical need for methods and communication infrastructures that can enable distributed...
The boom around cloud computing has reached to crown. Some professionals believe it's an absolutely new trend representing the next level of the Internet evolution. Others believe it's hype, as it uses long established computing technologies. This paper analyze cloud computing technology from different points of view and presents the findings in order to figure out the benefits and risks of cloud...
