This paper discusses the open issues in incorporating trust techniques in the NFV environment specified by the ETSI NFV Industry Specification Group, and analyses the available technologies to fill this gap. ETSI is developing security and trust specifications within its NFV-SEC working group, with the aim of establishing and assessing trust of both the hardware platform and the virtualised infrastructure...
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...
In the past, virtualisation, and with it the move toward the cloud, has had a strong influence on the ICT (Information Communication Technology) sector, and now seems set to revolutionise the telecommunications sector as well. The virtualisation into software artefacts of functions that would usually be deployed as hardware has come to be known as Network Function Virtualisation (NFV), and the European...
Statistics show the volume of Earth Observation (EO) data increases in the exponential level during the past decade. As the new generation computing platform to meet the big data challenge, cloud computing significantly facilitates the large-scale EO data processing depending on its powerful computing capability. In this paper, we propose a Cloud WPS architecture integrating the cloud computing environment...
Nowadays, more and more Cloud providers are appearing on the market. In this context, a typical issue is represented by the management of distributed services deployed on different federated Cloud providers. Assuming that a distributed service consists of several microservices, in this paper, we specifically focus on the setup of virtual environments and on deployment tasks required in each Federated...
The incredible rapid development of internet technologies, primarily thanks to omnipresent access of high speed broadband internet access and supporting technologies like Big Data, Cloud Computing, REST/Web services as well as cheap electronic equipment that use new wireless communications standards, lead to equal rapid growth of number of smart devices - “things” - connected to the internet. Increased...
Cloud computing is becoming a relatively mature paradigm in the ICT landscape. In light of the growing appetite for resources and service levels on par with user expectations, multi-cloud scenarios are becoming the next frontier in the usage of distributed datacenters for private and hybrid Cloud scenarios. Application deployment in particular is a noteworthy feature to be evaluated as microservices...
The need for customer-centric agile integrated environment offered in an on-demand self-service manner challenges the traditional R&E operations support systems. The service provider architecture proposed in this paper aims to satisfy end-user's requirements by providing a coordinated provisioning of virtualized resources through automation. Empowered by the establishment of open collaborative...
Service-oriented systems are often at the core of mission- or business-critical systems, and thus advanced quantitative analysis techniques are needed to assess, from the early development stages, whether or not the system accomplishes the stakeholder requirements and constraints. In this respect, in order to take advantage of the distributed nature of the considered systems, the use of distributed...
Every industry is adopting Cloud Computing platform due to its low cost services and zero overheads of maintenance and upgrades. Several new issues are generated because of this wide adoption which are concern to both cloud service provider and cloud service users. Cloud service providers are facing the issue of resource limitations. Cloud service users are facing the issue of vendor lock-in. Federated...
The OpenSON-MDCM provides an OpenStack API provisioning automation to allow multiple OpenStack instances, spanning in one site or multiple sites or in hybrid cloud, to be managed as a single OpenStack cloud.
Heterogeneous data and various system that manage data in organization can be one of the difficult factor to manage data and application. SOA proposed several years ago boast an open standard based on loosely coupled architecture for better integrating application in distributed and heterogeneous environment. ESB is introduced as infrastructure for SOA service connection and message exchange that...
The capability to operate cloud-native applications can generate enormous business growth and value. But enterprise architects should be aware that cloud-native applications are vulnerable to vendor lock-in. We investigated cloud-native application design principles, public cloud service providers, and industrial cloud standards. All results indicate that most cloud service categories seem to foster...
Cloud computing enables the on-demand delivery of resources for a multitude of services and gives the opportunity for small agile companies to compete with large industries. In the telco world, cloud computing is currently mostly used by mobile network operators (MNO) for hosting non-critical support services and selling cloud services such as applications and data storage. MNOs are investigating...
Complex application deployment and management over multiple heterogeneous PaaS platform is one of the key problems that have emerged with the cloud technology revolution. Presently, vendor lock-in has become a major PaaS technology challenge. Multi-Cloud PaaS Architecture (MCPA) has been recently proposed research project, intended to resolve complexity and interoperability challenges. MCPA offers...
Network Functions Visualization is focused on migrating traditional hardware-based network functions to software-based appliances running on standard high volume severs. There are a variety of challenges facing early adopters of Network Function Virtualizations; key among them are resource and service mapping, to support virtual network function orchestration. Service providers need efficient and...
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...
Nowadays, the Open Archive Information System (OAIS) model is widely adopted in hospitals to manage data related to both doctors and patients. However, the Archival Storage systems of hospitals are typically based on old Relational Database Management Systems (RDBMS) that makes hard the management of patients' data especially in the Health Level 7 (HL7) format. In fact, data have to be continuously...
This paper introduces XMPP and suggests how this technology might be used to help implement Intercloud communication. It gives an introduction to XMPP and how the architecture fits together as well as a discussion of the services it provides 'out of the box'. It then discusses secondary benefits of the protocol and highlights how XMPP could be an appropriate base protocol for implementing the Intercloud...
