A New Conception of Load Balancing in Cloud Computing Using Tasks Classification Levels

Abstract

Cloud users can have access to the service based on “pay as you go.” The daily increase of cloud users may decrease the performance, the availability and the profitability of the material and software resources used in cloud service. These challenges were solved by several load balancing algorithms between the virtual machines of the data centers. In order to determine a new load balancing improvement; this article's discussions will be divided into two research axes. The first, the pre-classification of tasks depending on whether their characteristics are accomplished or not (Notion of Levels). This new technique relies on the modeling of tasks classification based on an ascending order using techniques that calculate the worst-case execution time (WCET). The second, the authors choose distributed datacenters between quasi-similar virtual machines and the modeling of relationship between virtual machines using the pre-scheduling levels is included in the data center in terms of standard mathematical functions that controls this relationship. The key point of the improvement, is considering the current load of the virtual machine of a data center and the pre-estimation of the execution time of a task before any allocation. This contribution allows cloud service providers to improve the performance, availability and maximize the use of virtual machines workload in their data centers.

PE-DCA: Penalty elimination based data center allocation technique using guided local search for IaaS cloud

“…To solve the joint resource allocation task scheduling problem, Pan et al [36] proposed a Tabu search-based heuristic approach for cloud computing. Hamza et al [37] discussed a hybrid approach using Tabu search and simulated annealing for load balancing in cloud computing. In [38] authors proposed a new meta-heuristic approach for data center allocation with minimum cost, response time, and processing time.…”

Impact of Self-Directed Learning and Educational Technology Readiness on Synchronous E-Learning

“…For instance, recent blockchain technology can be used for authentication and authorization of a system (Esposito et al, 2021) and enhance the traceability and trackability of the system to enhance management (Ho et al, 2021). On the other hand, other advanced technologies such as the IoT-based system and cloud computing can be used for data processing and providing and sharing of teaching materials and management (Al-Qerem et al, 2020;Youssef et al, 2018). Furthermore, the latest AI technology can be used for data mining (Li et al, 2019) to investigate student learning patterns to determine the appropriate teaching pedagogy to students participating in e-learning.…”
