Abstract
Cloud computing is Internet based development and use of computer technology. It is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. Cloud computing is a hot topic all over the world nowadays, through which customers can access information and computer power via a web browser. As the adoption and deployment of cloud computing increase, it is critical to evaluate the performance of cloud environments. Currently, modeling and simulation technology has become a useful and powerful tool in cloud computing research community to deal with these issues. Cloud simulators are required for cloud system testing to decrease the complexity and separate quality concerns. Cloud computing means saving and accessing the data over the internet instead of local storage. In this paper, we have provided a short review on the types, models and architecture of the cloud environment.
Highlights
Cloud computing is an internet-based computing technology, where shared resources such as software, platform, storage and information are provided to customers on demand
The exact definition of cloud computing is A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet [5]
Software, information via internet are the main functions of cloud computing with an objective to reduced capital and operational cost, better performance in terms of response time and data processing time, maintain the system stability and to accommodate future modification in the system .So there are various technical challenges that needs to be addressed like Virtual machine migration [20], server consolidation, fault tolerance, high availability and scalability but central issue is the load balancing, it is the mechanism of distributing the load among various nodes of a distributed system to improve both resource utilization and job response time while avoiding a situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work
Summary
Cloud computing is an internet-based computing technology, where shared resources such as software, platform, storage and information are provided to customers on demand. Cloud computing is a computing platform for sharing resources that include infrastructures, software, applications, and business processes. The exact definition of cloud computing is A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet [5]. Cloud computing systems provide various Internet based data storage and services. Infrastructure-as-a-Service (IaaS) is offered in the bottom layer, where resources are aggregated and managed physically (e.g., Emulab) or virtually (e.g., Amazon EC2), and services are delivered in forms of storage (e.g., GoogleFS), network (e.g., Open ow), or computational capability (e.g., Hadoop MapReduce). Cloud computing is typically classified in two ways [9]: 1. Location of the cloud computing
