3rd International Conference of Computer Science and Renewable Energies, ICCSRE 2020

Since the 2000s, the idea that the Internet could be used for machine-to-machine communication and process automation has emerged. Together with the development of electronic objects capable of communicating with IP protocols, this idea led to the concept of the Internet of Things (IoT Internet of Things). Nowadays, the evolution of networks is very intense. New networks are appearing, "all-optical"solutions in the heart of networks, "wireless"solutions to facilitate access to users or to implant sensors / actors in places difficult to access, or finally the Internet of communicating objects. In this evolution, new scientific issues and challenges are emerging. Some of the problems are related to the optimization of generated traffic as well as the improvement of the performance of tools and techniques. Often, these optimization problems lead to models using graphs. The analysis of optimization problems in networks is an important activity. IOT networks create more data traffic that is difficult to control within the operator's network. The method given in this paper will help network operators optimize their networks and assist developers in improving hardware and software interactions to reduce data traffic in the network. © The Authors, published by EDP Sciences, 2021.

Hypervisor-based virtualization and containerization offer abstraction capabilities that make applications independent of the cloud’s hardware infrastructure for migration. Live migration is a widely used technology for load balancing, fault tolerance and energy saving in Cloud Datacenters. In this paper, we will be converging the two types of virtualization (Container and VMs together) into a hybrid architecture that promotes their complementarities without altering or degrading the quality of service (QoS) of the Cloud infrastructure. For this, we studied the live migration of a monolithic application and precisely the video streaming installed in a container nested in a virtual machine. We examined the contribution of this new type of virtualization in terms of processor utilization, disk usage, total migration time and downtime. The results presented show the advantages of Hybrid virtualization especially in terms of total migration time. Indeed, the absence of a real virtualization layer in the containers leads to a rapid interaction with the operating system processes, which affects the total migration time. © 2019, Springer International Publishing AG, part of Springer Nature.

Cloud Management Platforms (CMP) have been developed in recent years to set up cloud computing architecture. Infrastructure-as-a-Service (IaaS) is a cloud-delivered model designed by the provider to gather a set of IT resources which are furnished as services for user Virtual Machine Image (VMI) provisioning and management. Openstack is one of the most useful CMP which has been developed for industry and academic researches to simulate IaaS classical processes such as launch and store user VMI instance. In this paper, the main purpose is to adopt a security policy for a secure launch user VMI across a trust cloud environment founded on a combination of enhanced TPM remote attestation and cryptographic techniques to ensure confidentiality and integrity of user VMI requirements.

Hypervisor-based virtualization and containerization offer abstraction capabilities that make applications independent of the cloud's hardware infrastructure for migration. Cloud Elasticity is the ability to adapt to workload changes by provisioning and de-provisioning resources. There are two types of elasticity: horizontal and vertical also live migration. The later plays a big role in cloud elasticity. Virtual machine (VM) and container migration in Dynamic Resource Management (DRM) is a crucial factor in minimizing the cost of datacenter operation. Live migration is a widely used technology for load balancing, fault tolerance and energy saving in Cloud Datacenters. In this paper, we will be converging the two types of virtualization (Container and VMs together) into a hybrid architecture that promotes their complementarities without altering or degrading the quality of service (QoS) of the Cloud infrastructure. For this, we studied the live migration of a monolithic application and precisely the video streaming installed in a container nested in a virtual machine. We examined the contribution of this new type of virtualization in terms of processor utilization, disk usage, total migration time and downtime. The results presented show the advantages of Hybrid virtualization especially in terms of total migration time. Indeed, the absence of a real virtualization layer in the containers leads to a rapid interaction with the operating system processes, which affects the total migration time. To finish we will explore the live migration in the case of multiCloud, we show that live migration allows better management of material and energy resources. © 2018, The Authors.
