A major threat to cloud infrastructure network is distributed denial of service (DDoS) attacks. It makes the resources unavailable for its anticipated users, which can be accomplished through malicious virtual machines (VMs) in a hypervisor layer of cloud datacenter. Less protection in VMs leads to DDoS attacks on cloud environment. Traditional approaches used data flow based method, but that i...

Cloud computing datacenters provide millions of virtual machines in actual cloud markets. In this context, Virtual Machine Placement (VMP) is one of the most challenging problems in cloud infrastructure management, considering the large number of possible optimization criteria and different formulations that could be studied. In the existing literature, the VMP problem is mostly formulated as a...

Cloud computing provides a means to store and process data through a collection of resources which can be accessed online. Cloud is a collection of storage and physical machines which are termed as datacenter. Cloud consists of many datacenters located at geographically different places. Every physical machine of datacenter can handle more than one user. Virtualization is the technology behind ...

1. INTRODUCTION Recently, there is an increasing interest on cloud computing and it has become a clear trend of information technology over the world. Cloud computing providers such as Amazon (Amazon online 2008), Google, and IBM has already built large scale cloud platforms and started to provide a wide range of services such as computing resources renting and online documents to end users inc...

Monitoring and analyzing virtual machines (VMs) in a datacenter enables a cloud provider to place them on fewer physical machines with negligible performance penalty, a process which is known as the VM consolidation. Such a consolidation allows the cloud provider to take advantage of dissimilar workloads to reduce the number of ON servers, and thereby, reduce the datacenter energy consumption. ...

Traditional cloud systems are designed to tolerate server or rack-level failures that are uncorrelated and unpredictable. Such systems successfully deliver highly-available cloud services at global scale. However, the increasing criticality of cloud services to the overall world economy is causing concerns about the impact of power/network outages, cyber-attacks, administration errors, or other...

Information and communication technology (ICT) has a profound impact on environment because of its large amount of CO2 emissions. In the past years, the research field of ‘‘green’’ and low power consumption networking infrastructures is of great importance for both service/network providers and equipment manufacturers. An emerging technology called Cloud computing can increase the utilization a...

­The volume of generated data increases by the rapid growth of Internet of Things (IoT), leading to the big data proliferation and more opportunities for data centers. Highly virtualized cloud-based datacenters are currently considered for big data analytics. However big data requires datacenters with promoted infrastructure capable of undertaking more responsibilities for handling and analyzin...

Hyper-converged Infrastructure (HCI) is becoming a significant services platform in the datacenter, and with good reason. Abstracting processing, storage and network resources to create a fully software-defined datacenter is the logical progression of the decade-long virtualization trend. Companies like Nutanix are leading the way, enabling IT departments to create and expand application enviro...

Cloud computing is a quickly emerging field in computer science. It offers a wide variety of advantages over the traditional computing systems. Fast provisioning of resources, low upfront payment, minimal infrastructure management issues and so on. These enticing benefits offered by cloud computing has made it viable for many small organizations and keen individual developers as well. All of th...
