Fast IT development combined with diverse range of requests for IT services have led to the establishment of huge energy hungry data centers all around the world. Consolidation is proposed as one of the most effective methods for energy saving in modern cloud data centers. This paper addresses multi target resource allocation for cloud data centers that applies a holistic view to the resource a...

Cloud computing is an evolving and fast-growing computing paradigm that has gained great interest from both industry and academia. Consequently, universities are actively integrating cloud computing into their IT curricula. One major challenge facing cloud computing instructors is the lack of a teaching tool to experiment with. This paper introduces TeachCloud, a modeling and simulation environ...

rganizations needed a way to unify authentication systems in the enterprise for easier management and better security. Single-sign-on was widely adopted and provided a solution for keeping one repository of usernames and passwords that could be used transparently across several internal applications. After analyzing various issues regarding authentication of user’s in federated systems we have ...

Nowadays service oriented computing requires enlarging the virtualized datacenters. Quality of service has been the sole concern in cloud datacenter deployment. This demand will increase the operational cost and carbon dioxide emissions. Virtualization technology support Virtual Machine consolidation and migration. This will improve the server utilization, availability, fault tolerance and ener...

Optimal resource utilization for executing tasks within the cloud is one of the biggest challenges. In executing the task over a cloud, the resource provisioner is responsible for providing the resources to create virtual machines. To utilize the resources optimally, the resource provisioner has to take care of the process of allocating resources to Virtual Machine Manager (VMM). In this paper,...

Nowadays, Cloud computing is widely used in companies and enterprises. However, there are some challenges in using Cloud computing. The main challenge is resource management, where Cloud computing provides IT resources (e.g., CPU, Memory, Network, Storage, etc.) based on virtualization concept and pay-as-you-go principle. The management of these resources has been a topic of much research. In t...

The core idea of cloud computing is managing and scheduling uniformly computing resources that are connected by a network to provide user services according to the needs. One of the important issues in this environment is related to task scheduling. The scheduler should do the scheduling process efficiently in order to utilize the available resources. In this paper, a particle swarm optimizatio...

Containers are increasingly gaining popularity and becoming one of the major deployment models in cloud environments. To evaluate the performance of scheduling and allocation policies in containerized cloud data centers, there is a need for evaluation environments that support scalable and repeatable experiments. Simulation techniques provide repeatable and controllable environments and hence t...

Cloud computing is a popular computing model as it renders service to large number of users request on the fly and has lead to the proliferation of large number of cloud users. This has lead to the overloaded nodes in the cloud environment along with the problem of load imbalance among the cloud servers and thereby impacts the performance. Hence, in this paper a heuristic Baye's theorem approac...

Abstract This paper is aimed at efficiently distributing workload between the Fog Layer and Cloud Network then optimizing resource allocation in cloud networks to ensure better utilization quick response time of resources available end user. We have employed a Dead-line aware scheme migrate data based on profiling used K-Means clustering Service-request prediction model allocate all requests. T...
