Confidentiality and integrity of data in Infrastructure-as-a-Service (IaaS) environments increase in relevance as adoption of IaaS advances towards maturity. While current solutions assume a high degree of trust in IaaS provider staff and infrastructure management processes, earlier incidents have demonstrated that neither are impeccable. In this paper we introduce Domain-Based Storage Protecti...

Abstract—IaaS clouds invest substantial capital in operating their data centers. Reducing the cost of resource provisioning, is their forever pursuing goal. Computing resource trading among multiple IaaS clouds provide a potential for IaaS clouds to utilize cheaper resources to fulfill their jobs, by exploiting the diversities of different clouds’ workloads and operational costs. In this paper,...

Cloud computing and Infrastructure-as-a-Service (IaaS) are emerging and promising technologies, however their adoption is hampered by data security concerns. At the same time, Trusted Computing (TC) is experiencing an increasing interest as a security mechanism for IaaS. In this paper we present a protocol to ensure the launch of a virtual machine (VM) instance on a trusted remote compute host....

Server virtualization technology achieves ”Infrastructure as a Service (IaaS)” model services. Anyone can use virtual server resource easily without preparing computer hardware, thus IaaS environments provides multiple operational benefits to users. Therefore, today various types of users, not only personal users but also enterprise users, deploy virtual resources on IaaS cloud. On the other ha...

Cloud computing is an emerging paradigm to provide Infrastructure as a Service (IaaS). In this paper we present NEPTUNE-IaaS, a software system able to support the whole lifecycle of IaaS provisioning in a Virtual Cluster environment. Our system allows interactive design of complex system topologies and their efficient mapping onto the available physical resources of a cluster. It also provides...

Cloud computing and Infrastructure-as-a-Service (IaaS) are emerging and promising technologies, however their faster-pased adoption is hampered by data security concerns. In the same time, Trusted Computing (TC) is experiencing a revived interest as a security mechanism for IaaS. We address the lack of an implementable mechanism to ensure the launch of a virtual machine (VM) instance on a trust...

Open source IaaS is hot topic in cloud computing and every year a new IaaS with a different design is announced. This paper provides a closer look into three common IaaS; Eucalyptus, OpenStack & Nimbus. OpenStack is currently the best choice of public cloud providers due to its aim at standardization and scalability while Eucalyptus is more appropriate for private cloud deployments.

Infrastructure as a Service (IaaS) is one of the most important layers of Cloud Computing. However, there is an evident deficiency of mechanisms for analysis, comparison and evaluation of IaaS cloud implementations, since no unified taxonomy or reference architecture is available. In this article, we propose a unified taxonomy and an IaaS architectural framework. The taxonomy is structured arou...

Solving of tasks for Cloud Computing is impossible without maintaining of high availability level of Infrastructure as a Service (IaaS) Cloud. Several large IaaS Cloud providers try to solve this problem by means of increasing number of physical machines (PMs) in multiple pools. However, migrations of available PMs from one pool to another and also repairs, diagnostic instances of failed physic...

An important basis for cloud computing are public IaaS cloud services as offered e.g. by Amazon, Rackspace, VmWare. Since IaaS cloud services are often used as a flexible infrastructure for SaaS cloud services, it is important to investigate IaaS cloud services as a basis to realise regulatory requirements in cloud computing, e.g the European Data Protection Directive and the E-Privacy Directiv...
