Despite the great benefits of cloud computing on businesses, some organizations have had to withdraw from its service due to incomplete compliance to conditions from standards, bodies, or Service Level Agreements which have led to their being penalized. A structured and efficient model is helpful to aid small and medium scale enterprises (SMSEs) utilize cloud services safely and ascertain their fitting...
Energy interconnection (EI) is a logical consequence when ideas of open source and distributed scheme from the information field are introduced into the energy field. EI is essentially a typical cyber-physical system. This paper studies the new capabilities in sensing, computation, communication and control by analyzing its characteristics and demand. Firstly, we analyze the system architecture of...
In the era of Big Data, software systems can be affected by its growing complexity, both with respect to functional and non-functional requirements. As more and more people use software applications over the web, the ability to recognize if some of this traffic is malicious or legitimate is a challenge. The traffic load of security controllers, as well as the complexity of security rules to detect...
The paper proposes the method of building the electric power marketing business application system based on the cloud computing and microservices architecture technologies to solve the issues of the current system with the concentrated infrastructure and the monolithic architecture which are difficult to support the business processing in very large scale and the evolution of the electric power marketing...
Microservice architectures provide small services that may be deployed and scaled independently of each other, and may employ different middleware stacks for their implementation. Microservice architectures intend to overcome the shortcomings of monolithic architectures where all of the application's logic and data are managed in one deployable unit. We present how the properties of microservice architectures...
Today's Enterprises are facing many challenges in the service oriented, customer experience centric and customer demand driven global environment where ICT is becoming the leading enabler and partner of the modern enterprise. In the last decade, many enterprises have invested heavily in SOA-aligned IT transformations, but not harvested what SOA promised to provide. Now the API and Microservice paradigm...
Network function virtualization (NFV) is a promising solution for cost reduction, service agility, and scalability to cope with the dynamic changes of traffic volume and business requirements. In the NFV framework, management and orchestration framework (MANO) plays an important roles in the automated provisioning, configuration, lifecycle management, and high availability of virtual network functions...
The article touches upon issues pertaining to the domain of IT infrastructure modeling in electronic university. It describes the approach of IT infrastructure modeling based on system and process principals, and decomposition method. The functional modeling of business processes of providing e-learning services and designing IT infrastructure has been performed. Supporting ITIL/ITSM processes with...
Enterprises are under great pressure to be nimble and adjust quickly to ever shifting business priorities and constantly evolving technologies. This is usually seen as a driver to adopt Cloud technologies, however, the existing large investments in on premise IT infrastructure and data residency constraints combined with decreasing IT budgets precludes a fast and immediate migration to public or private...
Cloud computing has become the norm in the provisioning of computing resources due to its flexible and proven reliability. Businesses perceive cloud services as a trend that presents enormous possibilities both in economic and technical terms. The growth in cloud services have also increased bottlenecks and security risks to business assets. Cloud security monitoring has remained relatively unexplored...
In order to achieve the expected benefits provided by network function virtualization and software defined networks, the key role is placed on management and orchestration functionality with goal to automate services provider business processes. Network function virtualization and software defined networks establish new requirements upon network management systems which demand a change of existing...
Sustainable energy sources such as renewable energies are replacing dirty sources of energy in order to address the environmental challenges of the century. In order to operate data centres with renewable energies we have to mitigate their volatile and variable nature. In this paper, we present the Energy Adaptive Software Controller (EASC), a generic software controller and interface that developers...
This paper describes a functional view of a privacy architecture based on a shared-services model. The architecture exposes 7 functional management components: Master Management, Privacy Monitoring, Private Data Identification, Policy Management, Privacy Service Injection, Privacy Logging, and Privacy Analytics for (re)use by multiple applications operating in heterogeneous Big Data environments....
Today, the main limit for an efficient exploitation of resources owned by one or more IaaS environments is not technical, but structural: users and providers have two different views that rarely are really integrated. Cloud users have a deep knowledge about their workflows, but they don't have any details about the real state of the IaaS physical resources. Cloud providers have the opposite problem:...
Aggregators are considered to be a key enabling technology for harvesting power system services from distributed energy resources (DER). As a precondition for more widespread use of aggregators in power systems, methods for comparing and validating aggregator designs must be established. This paper proposes a functional reference architecture for aggregators to address this requirement.
Enterprises face the challenge of rapidly adapting to dynamic business environments. The traditional approach to process management is only partially appropriate to this new context, and calls for the advent of new, evolutionary business processes. This new approach attempts to address specific issues related to flexibility and adaptation such as design of easily adaptable processes, dynamic handling...
Virtual Communities (VCs) are dominating our daily activities from different insights. Social, Business, Professional, Educational and many VCs are competing to conquer the cloud by targeting more audience through the services they provide. The diversity, magnitude and quality of provided services raise a new challenge for managing these services. Consequently, the success or failure of VCs depends...
A key feature of Cloud computing is its agility and flexibility to support the scalability needs of business solutions. Currently, the agility is only limited to the scalability of the compute, memory and storage. To improve an application's agility, we need to monitor & measure solution level metrics and associate the performance of the metrics to the business agility needs of the solution...
In this paper we investigate synergies between Network Functions Virtualization (NFV) architectures and Software-Defined Networks (SDN). We identify value adding capabilities such technologies may offer to telecom providers regarding agile management and deployment of network functions across their infrastructures. Specifically, we propose a modular NFV architecture that permits policy-based management...
Software Defined Networking (SDN) is supposed to bring flexibility, dynamicity and automation to today's network through a logically centralized network controller. We argue that reaching SDN's full capacities requires however the development of standardized programming capabilities on its top. In this paper we introduce “Bring Your Own Control” (BYOC) as a new concept providing a convenient framework...
