An organization’s operational risk is a significant barrier to its growth. A bit of negligence could cause the business’s standing to erode rapidly. Increasing funding management and forecasting risks is essential for the successful development of companies, enhancing their competitiveness in the marketplace and minimizing negative effects.

However, current approaches are limited by various factors such as network latency, bandwidth, energy consumption, task characteristics, and edge server overload. To address these limitations, this research propose a novel approach that integrates Deep Reinforcement Learning (DRL) with Deep Deterministic Policy Gradient (DDPG) and Markov Decision Problem for task offloading in MEC. Among DRL algorithms, the ITODDPG algorithm based on the DDPG algorithm and MDP is a popular choice for task offloading in MEC. Firstly, the ITODDPG algorithm formulates the task offloading problem in MEC as an MDP, which enables the agent to learn a policy that maximizes the expected cumulative reward. Secondly, ITODDPG employs a deep neural network to approximate the Q-function, which maps the state-action pairs to their expected cumulative rewards. Finally, the experimental results demonstrate that the ITODDPG algorithm outperforms the baseline algorithms regarding average compensation and convergence speed. In addition to its superior performance, our proposed approach can learn complex non-linear policies using DNN and an information-theoretic objective function to improve the performance of task offloading in MEC. Compared to traditional methods, our approach delivers improved performance, making it highly effective for developing IoT environments. Experimental trials were carried out, and the results indicate that the suggested approach can enhance performance compared to the other three baseline methods. It is highly scalable, capable of handling large and complex environments, and suitable for deployment in real-world scenarios, ensuring its widespread applicability to a diverse range of task offloading and MEC applications.</p>","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138537018","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}

Current scholarly discussions heavily focus on effectively reducing the scheduling length (makespan) of parallel task sets and improving the efficiency of large workflow applications in cloud computing environments. Effectively managing task dependencies and execution sequences plays a crucial role in designing efficient workflow scheduling algorithms. This study forwards a high-efficiency workflow scheduling algorithm based on predict makespan matrix (PMMS) for heterogeneous cloud computing environments. First, PMMS calculates the priority of each task based on the predict makespan (PM) matrix and obtains the task scheduling list. Second, the optimistic scheduling length (OSL) value of each task is calculated based on the PM matrix and the earliest finish time. Third, the best virtual machine is selected for each task according to the minimum OSL value. A large number of substantial experiments show that the scheduling length of workflow for PMMS, compared with state-of-the-art HEFT, PEFT, and PPTS algorithms, is reduced by 6.84%–15.17%, 5.47%–11.39%, and 4.74%–17.27%, respectively.

{"title":"An Auto-Scaling Approach for Microservices in Cloud Computing Environments","authors":"Matineh ZargarAzad, Mehrdad Ashtiani","doi":"10.1007/s10723-023-09713-7","DOIUrl":"https://doi.org/10.1007/s10723-023-09713-7","url":null,"abstract":"<p>Recently, microservices have become a commonly-used architectural pattern for building cloud-native applications. Cloud computing provides flexibility for service providers, allowing them to remove or add resources depending on the workload of their web applications. If the resources allocated to the service are not aligned with its requirements, instances of failure or delayed response will increase, resulting in customer dissatisfaction. This problem has become a significant challenge in microservices-based applications, because thousands of microservices in the system may have complex interactions. Auto-scaling is a feature of cloud computing that enables resource scalability on demand, thus allowing service providers to deliver resources to their applications without human intervention under a dynamic workload to minimize resource cost and latency while maintaining the quality of service requirements. In this research, we aimed to establish a computational model for analyzing the workload of all microservices. To this end, the overall workload entering the system was considered, and the relationships and function calls between microservices were taken into account, because in a large-scale application with thousands of microservices, accurately monitoring all microservices and gathering precise performance metrics are usually difficult. Then, we developed a multi-criteria decision-making method to select the candidate microservices for scaling. We have tested the proposed approach with three datasets. The results of the conducted experiments show that the detection of input load toward microservices is performed with an average accuracy of about 99% which is a notable result. Furthermore, the proposed approach has demonstrated a substantial enhancement in resource utilization, achieving an average improvement of 40.74%, 20.28%, and 28.85% across three distinct datasets in comparison to existing methods. This is achieved by a notable reduction in the number of scaling operations, reducing the count by 54.40%, 55.52%, and 69.82%, respectively. Consequently, this optimization translates into a decrease in required resources, leading to cost reductions of 1.64%, 1.89%, and 1.67% respectively.</p>","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138536995","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 number of IoT devices is increasing exponentially, and generating huge amounts of data that IoT nodes cannot handle. The centralized cloud architecture can process this enormous IoT data but fails to offer quality of service (QoS) due to high transmission latency, network congestion, and bandwidth. The fog paradigm has evolved that bring computing resources at the network edge for offering services to latency-sensitive IoT applications. Still, offloading decision, heterogeneous fog network, diverse workload, security issues, energy consumption, and expected QoS is significant challenges in this area.

Yottabytes (YB) of information are being produced in the IoT environs because of the ever-increasing utilization capacity of the Internet. Since sensitive information, as well as privacy problems, always seem to be an unsolved problem, even with best-in-class in-formation governance standards, it is difficult to bolster defensive security capabilities. Secure data sharing across disparate systems is made possible by blockchain technology, which operates on a decentralized computing paradigm. In the ever-changing IoT environments, blockchain technology provides irreversibility (immutability) usage across a wide range of services and use cases. Therefore, blockchain technology can be leveraged to securely hold private information, even in the dynamicity context of the IoT. However, as the rate of change in IoT networks accelerates, every potential weak point in the system is exposed, making it more challenging to keep sensitive data se-cure. In this study, we adopted a Multi-level Blockchain-based Secured Framework (M-BSF) to provide multi-level protection for sensitive data in the face of threats to IoT-based networking systems. The envisioned M-BSF framework incorporates edge-level, fog-level, and cloud-level security. At edge- and fog-level security, baby kyber and scaling kyber cryptosystems are applied to ensure data preservation. Kyber is a cryptosystem scheme that adopts public-key encryption and private-key decryption processes. Each block of the blockchain uses the cloud-based Argon-2di hashing method for cloud-level data storage, providing the highest level of confidentiality. Argon-2di is a stable hashing algorithm that uses a hybrid approach to access the memory that relied on dependent and independent memory features.
