Infrastructure as a Service (IaaS) is a rapidly expanding model of cloud computing. It includes control of computing resources, such as memory, computing power and storage capacity, satisfying the most fundamental IT needs for businesses on a usage-based payment model. Currently, there is an increased demand for IaaS services, which in turn feeds competition among cloud providers. As the price ...

Children at risk for type 1 diabetes can develop early insulin autoantibodies (IAAs). Many, but not all, of these children subsequently develop multiple islet autoantibodies and diabetes. To determine whether disease progression is reflected by autoantibody maturity, IAA affinity was measured by competitive radiobinding assay in first and subsequent IAA-positive samples from children followed f...

The coordinated action of the auxin-sensitive Aux/IAA transcriptional repressors and ARF transcription factors produces complex gene-regulatory networks in plants. Despite their importance, our knowledge of these two protein families is largely based on analysis of stabilized forms of the Aux/IAAs, and studies of a subgroup of ARFs that function as transcriptional activators. To understand how ...

With the increase of centralization of resources in IT-infrastructure and the growing amount of cloud services, database management systems (DBMS) will be more and more outsourced to Infrastructure-as-a-Service (IaaS) providers. The outsourcing of entire databases, or the computation power for processing Big Data to an external provider also means that the provider has full access to the inform...

This paper proposes an architecture for optimized resource allocation in Infrastructure-as-a-Service (IaaS)-based cloud systems. Current IaaS systems are usually unaware of the hosted application’s requirements and therefore allocate resources independently of its needs, which can significantly impact performance for distributed data-intensive applications. To address this resource allocation p...

Infrastructure as services (IaaS) in Cloud computing offers the features of increasing the hardware resources (CPU cores, RAM, hard disk or storage space, and network bandwidth) on-demand in no time or utilizing the additional configured VMs to execute the business applications in a shortest time as possible by utilizing the dynamic scaling. The scheduling algorithm in the IaaS allows the appli...

Cloud Computing has became an emerging area in the recent areas. It extends services like SaaS, PaaS and IaaS. One of the complicated applications in Iaas is parallel data processing. Parallel data processing is needed to integrate and deploy their programs in customer premises. However, the processing frameworks which are currently used have been designed for static, homogeneous cluster setups...

Results of researches in different areas of science and technique confirm that an effective route in order to solve important tasks is the possibility of migrating data resource within the cloud. Therefore Cloud Computing services including Infrastructure as a Service Cloud (IaaS Cloud) should have high availability level. It is serious problem, because even large cloud providers face with sudd...

With the increasing maturity of various cloud service delivery models ( Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS)) and deployment models (Private, Community, Public, Hybrid), the security risk profile of each cloud service configuration is coming into focus. In this paper, we take up the example of a Public Infrastructure as a Service (Iaas) ...

The Infrastructure-as-a-Service (IaaS) model of cloud computing is a promising approach towards building elastically scaling systems. Unfortunately, building such applications today is a complex, repetitive and error-prone endeavor, as IaaS does not provide any abstraction on top of naked virtual machines. Hence, all functionality related to elasticity needs to be implemented anew for each appl...
