Since Infrastructure-as-a-Service (IaaS) clouds contain many vulnerable virtual machines (VMs), intrusion detection systems (IDSes) should be run for all the VMs. IDS offloading is promising for this purpose because it allows IaaS providers to run IDSes outside of VMs without any cooperation of the users. However, offloaded IDSes cannot continue to monitor their target VM when the VM is migrate...

Cloud computing is an increasingly popular paradigm for accessing computing resources. A popular class of computing clouds is Infrastructure as a Service (IaaS) clouds, exemplified by Amazon’s Elastic Computing Cloud (EC2). In these clouds, users are given access to virtual machines on which they can install and run arbitrary software, including database systems. Users can also deploy database ...

Parallel data processing has become more and more reliable phenomenon due to the realization of could computing, especially using IaaS (Infrastructure as a Service) clouds. The cloud service providers such as IBM, Google, Microsoft and Oracle have made provisions for parallel data processing in their cloud services. Nevertheless, the frameworks used as of now are static and homogenous in nature...

This paper introduces Elastic Cloud Computing Cluster (EC3), a tool that creates elastic virtual clusters on top of Infrastructure as a Service (IaaS) Clouds. The clusters are self-managed entities that scale out to a larger number of nodes on demand, up to a maximum size specified by the user. Whenever idle resources are detected, the clusters automatically scale in, according to some predefin...

Infrastructure as a service (IaaS) is a type of cloud computing in which a thirdparty provider hosts virtualized computing resources over the Internet for executing tasks in the cloud computing. Whenever some VMs are overloaded and some VMs are under loaded, this situation may cause to SLA violation and leads to the reduction of customer satisfaction level and further affects the cloud provider...

Infrastructure as a Service (IaaS) is one of the provisioning models for Clouds as defined in the NIST Clouds definition. Although widely used, current IaaS implementations and solutions doesn’t have common and well defined architecture model. The paper attempts to define a generic architecture for IaaS based on current research by authors in developing novel architectural framework for Infrast...

Parallel Data processing has emerged to be one of the killer applications for Infrastructure-as-a-Service (IaaS) clouds. One of an IaaS cloud’s key feature is the provisioning of compute resources on demand. The computer resources available in the cloud are highly dynamic and possibly heterogeneous. Nephele is the first data processing framework to explicitly exploit the dynamic resource alloca...
