INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 01, JANUARY 2020 ISSN 2277-8616 1513 IJSTR©2020 www.ijstr.org A Survey On Various Types Of Task Scheduling Algorithm In Cloud Computing Environment Priyanka Sharma , Dr. Sanjay Shilakari, Uday Chourasia, Priyanka Dixit, Alpana Pandey Abstract: Now a days, Cloud computing has become an significant and most popular computing model that usually supports on demand servic es. Cloud Computing provides its services on pay-as-you-go basis .By using cloud computing resources expeditiously and by reducing in managing time and cost and increasing the outcome of the project is the main idea of cloud service provider. Therefore, using effective cloud scheduling algorithms is still main concern in cloud computing. Task scheduling is a pivotal part in the field of the cloud environment. In task scheduling user requests for certain task, then tasks are scheduled to certain resources at a specific exemplification of time. Basically task scheduling mainly f ocuses to diminish the make span and lengthen the resource utilization. Task scheduling is an Non Polynomial-Complete problem. There are lots of subsisting trail-and-error techniques for task scheduling till now but more amelioration and rectification is needed for better execution and to increase the efficiency of task scheduling till now, there is no combined study of task scheduling mechanism in cloud computing which describes its parameter, pros, cons, algorithm. This paper mainly emphasis on explaining Comparison on different Task scheduling algorithm in cloud computing adaptive ————————————————————. 1. INTRODUCTION In the simplest term, Cloud computing means to storing and accessing data and programs over the Internet instead of your computer's hard drive. It is just an image for the Internet. The term network or Internet are also refers a cloud. In other words, we can say Cloud is something, which is present at remote location. Cloud can provide services over various types of network, i.e., on public networks or on private networks, i.e., Wide Area Network , Local Area Network or Virtual Private Network. There are various types of Applications run in cloud and they are-  e-mail  web conferencing  customer relationship management (CRM)  Online File storage  Photo editing software  Digital video software  Twitter-related applications  Creating image-album  Web application for antivirus  Word processing application  Spreadsheets  Presentation software  Finding a way on the map  E-commerce software.  The term Cloud Computing refers to manipulating, configuring, and accessing the applications online. The location of physical resources and devices being accessed are typically not known to the end user. Cloud also provides facilities for users to develop, deploy and manage their applications ‗on the cloud‘, which give rise to virtualization of resources that maintains and manages itself. In general, there are three cloud computing characteristics that are common among all cloud-computing venders: 1. The back end of the application (especially hardware) is completely managed by a cloud vendor. 2. A user only pays for services they used i.e. (.memory, processing time and bandwidth, etc). 3. Services are scalable 2. CLOUD MODELS In cloud models there are certain kinds of services and models which is functioning behind the scene making the cloud computing feasible and accessible to end users. There are two types of the working models for cloud computing:  Deployment Model  Service Models Figure.1 Cloud Models DEPLOYMENT MODELS A cloud deployment model is a ―configuration‖ of certain cloud environment parameter such as storage size, accessibility and proprietorship. Cloud deployment model can have four types of access i.e : Public, Private, Hybrid and Community.  PUBLIC CLOUD –The name speaks for itself , as the public clouds are available to the general public data are creatsed and stored on third-party servers. In other words, Public Cloud allows systems and services to be easily accessible to the general public. Examples of Public cloud deployment models are-Amazon Elastic ___________________________________  Priyanka Sharma Department of Computer Sciences Technology University of technology RGPV ,Bhopal  Dr. Sanjay Shilakari Department of Computer Sciences Technology University of technology ,RGPV Bhopal  Uday Chourasia Department of Computer Sciences Technology University of technology RGPV ,Bhopal  Priyanka Dixit ,Department of Computer Sciences TechnologyUniversity of technology RGPV ,Bhopal  Dr. Alpana Pandey ,MANIT ,Bhopal
