It has revolutionized the way businesses operate by providing a flexible and scalable infrastructure for their computing needs. Cloud providers offer a range of services with a variety of pricing schemes. Cloud pricing schemes are based on functional factors like CPU, RAM, and storage, combined with different payment options, such as pay-per-use, subscription-based, and non-functional aspects, such as scalability and availability. While cloud pricing can be complicated, it is critical for businesses to thoroughly assess and compare pricing policies along with technical requirements to ensure they design an investment strategy. This paper evaluates current pricing strategies for IaaS, CaaS, and PaaS cloud services and also focuses on the three leading cloud providers, Amazon, Microsoft, and Google. To compare pricing policies between different services and providers, a hedonic price index is constructed for each service type based on data collected in 2022. Using the hedonic price index, a comparative analysis between them becomes feasible. The results revealed that providers follow the very same pricing pattern for IaaS and CaaS, with CPU being the main driver of cloud pricing schemes, whereas PaaS pricing fluctuates among cloud providers.</p>","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":"163 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The network users request various services with specific Quality-of-Service (QoS) values. The QoS-aware Web Service Composition (WSC) methods assign available services to users’ tasks and significantly affect their satisfaction. Various methods have been provided to solve the QoS-aware WSC problem; However, this field is still one of the popular research fields since the dimensions of these networks, the number of their users, and the variety of provided services are growing outstandingly. Consequently, this study presents an enhanced Fox Optimizer (FOX)-based framework named EQOLFOX to solve QoS-aware web service composition problems in edge computing environments. In this regard, the Quasi-Oppositional Learning is utilized in the EQOLFOX to diminish the zero-orientation nature of the FOX algorithm. Likewise, a reinitialization strategy is included to enhance EQOLFOX's exploration capability. Besides, a new phase with two new movement strategies is introduced to improve searching abilities. Also, a multi-best strategy is recruited to depart local optimums and lead the population more optimally. Eventually, the greedy selection approach is employed to augment the convergence rate and exploitation capability. The EQOLFOX is applied to ten real-life and artificial web-service-based edge computing environments, each with four different task counts to evaluate its proficiency. The obtained results are compared with the DO, FOX, JS, MVO, RSA, SCA, SMA, and TSA algorithms numerically and visually.

Recognizing this, our study introduces a novel reference architecture, Cloud Monitoring Kit (CMK), for a multi-platform monitoring system.

Thus, distributing these loads among the virtual machines is crucial, in order to maximize resource utilization and enhance system performance, load balancing must be implemented that ensures balance across all virtual machines (VMs). In the proposed framework, a credit-based resource-aware load balancing scheduling algorithm (HO-CB-RALB-SA) was created using a hybrid Walrus Optimization Algorithm (WOA) and Lyrebird Optimization Algorithm (LOA) for cloud computing. The proposed model is developed by jointly performing both load balancing and task scheduling. This article improves the credit-based load-balancing ideas by integrating a resource-aware strategy and scheduling algorithm. It maintains a balanced system load by evaluating the load as well as processing capacity of every VM through the use of a resource-aware load balancing algorithm. This method functions primarily on two stages which include scheduling dependent on the VM’s processing power. By employing supply and demand criteria to determine which VM has the least amount of load to map jobs or redistribute jobs from overloaded to underloaded VM. For efficient resource management and equitable task distribution among VM, the load balancing method makes use of a resource-aware optimization algorithm. After that, the credit-based scheduling algorithm weights the tasks and applies intelligent resource mapping that considers the computational capacity and demand of each resource. The FILL and SPILL functions in Resource Aware and Load utilize the hybrid Optimization Algorithm to facilitate this mapping. The user tasks are scheduled in a queued based on the length of the task using the FILL and SPILL scheduler algorithm. This algorithm functions with the assistance of the PEFT approach. The optimal threshold values for each VM are selected by evaluating the task based on the fitness function of minimising makespan and cost function using the hybrid Walrus Optimization Algorithm (WOA) and Lyrebird Optimization Algorithm (LOA).The application has been simulated and the QOS parameter, which includes Turn Around Time (TAT), resource utilization, Average Response Time (ART), Makespan Time (MST), Total Execution Time (TET), Total Processing Cost (TPC), and Total Processing Time (TPT) for the 400, 800, 1200, 1600, and 2000 cloudlets, has been determined by utilizing the cloudsim tool. The performance parameters for the proposed HO-CB-RALB-SA and the existing models are evaluated and compared.

Many such applications can be represented as directed acyclic graphs (DAG). Device-edge-cloud fusion provides a new kind of heterogeneous, distributed, and collaborative computing environment to support various MEC applications. DAG scheduling is a procedure employed to effectively and efficiently manage and monitor the execution of tasks that have precedence constraints on each other. In this paper, we investigate the NP-hard problems of DAG scheduling and energy-constrained DAG scheduling on mobile devices, edge servers, and cloud servers by designing and evaluating new heuristic algorithms. Our contributions to DAG scheduling can be summarized as follows. First, our heuristic algorithms guarantee that all task dependencies are correctly followed by keeping track of the number of remaining predecessors that are still not completed. Second, our heuristic algorithms ensure that all wireless transmissions between a mobile device and edge/cloud servers are performed one after another. Third, our heuristic algorithms allow an edge/cloud server to start the execution of a task as soon as the transmission of the task is finished. Fourth, we derive a lower bound for the optimal makespan such that the solutions of our heuristic algorithms can be compared with optimal solutions. Our contributions to energy-constrained DAG scheduling can be summarized as follows. First, our heuristic algorithms ensure that the overall computation energy consumption and communication energy consumption does not exceed the given energy constraint. Second, our algorithms adopt an iterative and progressive procedure to determine appropriate computation speed and wireless communication speeds while generating a DAG schedule and satisfying the energy constraint. Third, we derive a lower bound for the optimal makespan and evaluate the performance of our heuristic algorithms in such a way that their heuristic solutions are compared with optimal solutions.

Aiming to optimize data placement for SW, this paper proposes EQGSA-DPW a novel algorithm leveraging quantum computing and swarm intelligence optimization to intelligently reduce costs and energy consumption when a SW is processed in multi-cloud. EQGSA-DPW considers multiple objectives (e.g., transmission bandwidth, cost and energy consumption of both service and communication) and improves the GSA algorithm by using the log-sigmoid transfer function as a gravitational constant <i>G</i> and updating agent position by quantum rotation angle amplitude for more diversification. Moreover, to assist EQGSA-DPW in finding the optima, an initial guess is proposed. The performance of our EQGSA-DPW algorithm is evaluated via extensive experiments, which show that our data placement method achieves significantly better performance in terms of cost, energy, and data transfer than competing algorithms.

These strategies encompass the implementation of load-balancing algorithms, dynamic scheduling, and virtualization techniques that generate logical instances of resources within the clusters. Moreover, the implementation of data management techniques is essential to facilitate effective data sharing among clusters.
