Tasks Scheduling Techniques in Cloud Computing

Cloud Computing considers one of the most significant innovations that has aroused the curiosity of technologists all around the world. It has many advantages, but it also has a large number of challenges that reduce the efficiency of this technology, including scheduling tasks, which is crucial for organizing user needs and achieving numerous objectives. Because cloud computing serves millions of users at once, it must be able to meet all user needs with excellent performance and a guarantee of the quality of service. Therefore, to fairly and effectively fulfill these requirements, a suitable tasks scheduling system is required. The scheduling solutions should be chosen to satisfy the varied user needs while minimizing the make-span and expense. Task scheduling is employed to assign specific tasks to specific resources at one particular time. The issues with task scheduling have been addressed using a wide variety of ways. Task scheduling's fundamental tenet is to prioritize performance and minimize time lost between activities. In this paper, an overview of the different scheduling approaches used in the cloud is proposed. This paper also discusses the scheduling parameters used in these methods. As well as this paper suggest scenario of scheduling framework that addresses the significant challenges of scheduling tasks in the cloud by dividing the incoming tasks into three groups based on critical tasks (insensitive task, sensitive task and more sensitive task) and other requirements such as minimum execution time or minimum of cost and prioritization.
