Toward a correct and optimal time-aware cloud resource allocation to business processes

© 2020 Elsevier B.V. Cloud is an increasingly popular computing paradigm that provides on-demand services to organizations for deploying their business processes over the Internet as it reduces their needs to plan ahead for provisioning resources. Cloud providers offer competitive pricing strategies (e.g., on-demand, reserved, and spot) specified based on temporal constraints to accommodate organizations’ changing and last-minute demands. Despite their varieties and benefits to optimize business process deployment cost, using those pricing strategies can lead to violating time constraints and exceeding budget constraints due to inappropriate decisions when allocating cloud resources to business processes. In this paper, we present an approach to guarantee a correct and optimal time-aware allocation of cloud resources to business processes. Correct because time constraints on these processes are not violated. And, optimal because the deployment cost of these processes is minimized. For this purpose, our approach uses timed automata to formally verify the matching between business processes’ temporal constraints and cloud resources’ time availabilities and linear programming to optimize deployment costs. Experiments demonstrate the technical doability of our proposed approach

A Repository of Cloud Services for Small and Micro Enterprises

Cloud Computing offers an opportunity to support the growth and development of small and microenterprises by enabling low cost Information Technology solutions delivered over the Internet to be made available to them so that they may adopt with little effort or skill. Since the ability of small and microenterprises to adopt technology depends upon the unique conditions in which they find themselves, we hope to facilitate this by investigating and assessing the ways in which Cloud Computing functionality and processes may support the growth of small and microenterprises. In this study, we do this through the creation of an online knowledge repository of Cloud Computing applications and services with direct correlations to addressing specific business needs of small and microenterprises. This serves as a very valuable source of information for local community small and microenterprises looking to adopt low cost Information Technology solutions to address common business needs

Situational Enterprise Services

The ability to rapidly find potential business partners as well as rapidly set up a collaborative business process is desirable in the face of market turbulence. Collaborative business processes are increasingly dependent on the integration of business information systems. Traditional linking of business processes has a large ad hoc character. Implementing situational enterprise services in an appropriate way will deliver the business more flexibility, adaptability and agility. Service-oriented architectures (SOA) are rapidly becoming the dominant computing paradigm. It is now being embraced by organizations everywhere as the key to business agility. Web 2.0 technologies such as AJAX on the other hand provide good user interactions for successful service discovery, selection, adaptation, invocation and service construction. They also balance automatic integration of services and human interactions, disconnecting content from presentation in the delivery of the service. Another Web technology, such as semantic Web, makes automatic service discovery, mediation and composition possible. Integrating SOA, Web 2.0 Technologies and Semantic Web into a service-oriented virtual enterprise connects business processes in a much more horizontal fashion. To be able run these services consistently across the enterprise, an enterprise infrastructure that provides enterprise architecture and security foundation is necessary. The world is constantly changing. So does the business environment. An agile enterprise needs to be able to quickly and cost-effectively change how it does business and who it does business with. Knowing, adapting to diffident situations is an important aspect of today’s business environment. The changes in an operating environment can happen implicitly and explicitly. The changes can be caused by different factors in the application domain. Changes can also happen for the purpose of organizing information in a better way. Changes can be further made according to the users' needs such as incorporating additional functionalities. Handling and managing diffident situations of service-oriented enterprises are important aspects of business environment. In the chapter, we will investigate how to apply new Web technologies to develop, deploy and executing enterprise services

Stochastic Workflow Scheduling with QoS Guarantees in Grid Computing Environments

Grid computing infrastructures embody a cost-effective computing paradigm that virtualises heterogenous system resources to meet the dynamic needs of critical business and scientific applications. These applications range from batch processes and long-running tasks to more real-time and even transactional applications. Grid schedulers aim to make efficient use of Grid resources in a cost-effective way, while satisfying the Quality-of-Service requirements of the applications. Scheduling in such a large-scale, dynamic and distributed environment is a complex undertaking. In this paper, we propose an approach to Grid scheduling which abstracts over the details of individual applications and aims to provide a globally optimal schedule, while having the ability to dynamically adjust to varying workloa

The new cloud computing paradigm: the way to IT seen as a utility

In the present competitive environment, companies are wondering how to reduce their IT costs while increasing their efficiency and agility to react when changes in the business processes are required. Cloud Computing is the latest paradigm to optimize the use of IT resources considering ?everything as a service? and receiving these services from the Cloud (Internet) instead of owning and managing hardware and software assets. The benefits from the model are clear. However, there are also concerns and issues to be solved before Cloud Computing spreads across the different industries. This model will allow a pay-per-use model for the IT services and many benefits like cost savings, agility to react when business demands changes and simplicity because there will not be any infrastructure to operate and administrate. It will be comparable to the well known utilities like electricity, water or gas companies. However, this paper underlines several risk factors of the model. Leading technology companies should research on solutions to minimize the risks described in this article. Keywords - Cloud Computing, Utility Computing, Elastic Computing, Enterprise Agilit

CLOUD COMPUTING ADOPTION FACTORS IN TURKISH LARGE SCALE ENTERPRISES

While most research regarding adoption of cloud computing by companies covers countries with highly developed IT infrastructure, cloud computing is actually used also in less IT-mature countries. Still, companies address cloud computing differently in countries with different levels of IT-maturity. This research explores cloud computing adoption factors in less IT-mature countries having Turkey as the example. Embracing an exploratory approach, we investigated five large Turkish companies. The results show that the main adoption factors in favour of cloud computing are “cost”, “distributed organisational structure”, “mobility of the employees”, and “end-user satisfaction”, while “security”, “critical business processes”, “loss of control over data and systems”, and “technical infrastructure of the region in terms of broadband” are the factors that make companies cautious about cloud computing. The main difference between Turkey and more IT-mature countries with respect to cloud computing adoption factors is inadequate broadband access and lack of knowledge on cloud computing
