The use of cloud computing is rapidly growing, with virtualization playing a key role in cloud data centers. Virtualization allows multiple VMs to run concurrently, improving hardware utilization [1]. Due to the dynamic nature of cloud resources, advanced scheduling methods are essential to allocate ...
With the popularization of cloud computing, cloud systems are applied in many fields. To improve the reliability of cloud systems, researchers contribute a lot in data dissemination [1], data management [2], and security [3]. Still, the fault greatly affected the reliability of cloud systems. ...
A hypervisor, also known as a virtual machine monitor (VMM), is software that creates and runs virtual machines (VMs). It allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing. There are two types of hypervisors: Type 1 (or...
From the perspective of hypervisor (also known as virtual machine monitor, VMM), tracing userland processes is straightforward and has been well-studied as a part of virtual machine introspection (VMI) (Jain et al.2014). Unfortunately, current VMI techniques can not deal with VNFs due to their...
of the cloud infrastructure incurs overhead due to additional I/O processing and communications with the Virtual Machine Monitor (VMM). These factors make it difficult to design such models and generators fitting different workload types and attributes. In the current state of the art, effort is...
Additionally, the proposed approach was successfully tested in a cross-VM scenario. Keywords: side-channel cache attacks; cache misses; AES; cloud computing 1. Introduction Cloud computing aims to provide its users with compute resources as they are required, eliminating the need of acquiring and ...
