One of the main goals in any computational system like cloud is to effectively allocate resources proficiently for task scheduling. However, dynamic characteristics make it more prone faults and failures. The flexible responsive changes are made redistribute virtual machines (VMs) address these failures maintaining continuous services. may inadvertently lead uneven load distribution. Therefore, thorough attention required ensure carefully monitored equilibrium following fault tolerance. Addressing all issues simultaneously with optimized Quality Service (QoS) parameters a good need time. In this paper, novel hybrid model: Hybrid Fault-tolerant Scheduling Load balancing Model (HFSLM) has been proposed optimize makespan dynamically arriving tasks efficiently utilize available VMs. Moreover, model also provides solutions several crucial concerns systems including VM failure, VM/task heterogeneity. consequence approach offers Neighbouring as substitute corresponding complete its execution. Furthermore, escorted by load-balancing algorithm maintain distribution after handling further optimization considered QoS parameters. HFSLM evaluated comparing FTHRM, MAX-MIN, MIN-MIN, OLB on small scale over diverse machine heterogeneities ELISA MELISA an extremely large scale. evaluation results show that recommended tops compared approaches cases heterogeneities.

In today’s world, a situational awareness of sustainability is becoming increasingly important. Leaving better world for future generations the main interest many studies. It also puts pressure on managers to change production methods in most industries. Reducing carbon emissions industry today crucial saving our planet. Theoretical research and practical requirements diverge, even though numerous researchers have tackled various strategies handle emission problems. Therefore, this work considers problem furniture manufacturing Hosur, Tamilnadu, India. The case study company has system that resembles hybrid flow shop (HFS) environment. As HFS scheduling problems are NP-hard nature, exact solution techniques could not be used solve Hence, sequential optimization algorithm (SHOA) been developed paper minimize footprint. SHOA, pigeon-inspired (PIOA) hybridized sequentially with firefly (FA). A computational experimental design proposed analyze efficiency introduced strategy, solutions indicate approach reduce footprint by up 9.82%. results motivate us implement

Cloud computing has gained prominence due to its potential for computational tasks, but the associated energy consumption and carbon emissions remain significant challenges. Allocating Virtual Machines (VMs) Physical (PMs) in cloud data centers, a known NP-hard problem, offers an avenue enhancing efficiency. This paper presents energy-conscious optimization approach utilizing Giant Trevally Optimizer (GTO) which is inspired by hunting strategies of giant trevally, proficient marine predator. Our study mathematically models trevally's behavior when targeting seabirds. The involves strategic selection optimal locations based on food availability, including pursuing seabird prey air or seizing it from water's surface. Through extensive simulations, our method demonstrates superior performance terms skewness, CPU utilization, memory overall resource allocation research promising addressing challenges centers while optimizing utilization sustainable cost-effective operations.

Virtualisation is a major technology in cloud computing for optimising the data centre’s power usage. In current scenario, most of services are migrated to cloud, putting more load on centres. As result, center’s size expands resulting increased energy To address this problem, resource allocation optimisation method that both efficient and effective necessary. The optimal utilisation infrastructure algorithms plays vital role. resources rely policy virtual machine resources.
