Taking a Look at Cloud Computing

Cloud computing is an emerging technology. With its huge demand, it is rapidly growing. Cloud computing is defined as "a type of Internet-based computing", where different services such as servers, storage and applications are delivered to an organization’s technological infrastructure through the Internet.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

Cloud computing has evolved with the passage of time and has revolutionized the entire ICT industry. Cloud computing is categorized into two forms Service oriented computing and Grid Computing. Service oriented Computing is an transpiring paradigm that has revamped the consumption of software and related product all around the globe. The core functionalities that service oriented computing provide is elements and that are independent of platforms and are programmed using standard protocols to support distributed computing across various organizations. [2]

Cloud computing, or “the cloud”, is defined by NIST as; “...a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” [1]

Cloud computing has become a compelling paradigm for delivering and managing services over the internet. Although it might be difficult to define cloud computing, one simple definition of the term is virtualized third-party hosting. In simple terms, instead of renting the entire or actual physical server, one rents a certain proportion of server resources. The client’s server runs within a virtual container that may be moved from a physical server to another without service interruption. Cloud computing has changed the entire landscape of Information Technology, and it is finally actualizing the long-standing promise of utility computing. This paper serves as a comprehensive overview of the cloud computing technology; definition,

Cloud computing is the growing method of computing adopted by many organizations nowadays around the world. The word ‘cloud’ refers to the network, the servers providing the cloud services can be located anywhere in the world (Garg & Buyya, 2012). The services are provided through internet and made available to the end users. Several definitions are given for the cloud computing in the literature. According to (Mell & Grance, 2011), “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This Cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” Different advantages of having cloud computing includes, services are available on demand, the users have to pay only as per the use and the services are accessible from anywhere as it is available over network. There are different service models and deployment models available for cloud computing.

Load stability is a process to achieve finest resource utilization, increase throughput, reduction response-time plus avoid under-provisioning. Static algorithms are less effective than the dynamic algorithms. Dynamic algorithm is helpful to allotment of load among virtual machines of the cloud at run time. This algorithm always uses previous load results to making distribution decisions. Due to these results dynamic load balancing algorithm give a major enhancement in performance over static algorithms [1]. Load balancing is a method to strength network data processing capability, increase the flexibility and availability of the network. Using multiple components with load balancing, instead of a single component, to provide external services can solve the problem of insufficient processing capacity of a single host, and can also solve the challenges posed by concurrent access due to the importance of load balancing scheduling, which is the key issue as this a scheduling algorithm based on dynamic policy. Although dynamic load balancing exerts immense stress on a system and each node needs to interchange status information periodically yet it is more advantageous when most of nodes work in individual manner with partial interaction with others.

Cloud computing is large group of remote servers which are networked for facilitating pervasive, expedient, on-demand network access to configurable and common computing resources such as CPU processing, network bandwidth, disk space that can be quickly facilitated and reclaimed with minimum central management. The underlying complexity of such a system is handled by an Operating System which is designed to support interoperability, scalability, security, user privacy, data management, fault tolerance. These operating systems need to work proficiently in the background to ensure that all the resources are available when needed and ensure acceptable performance and quality of service.

Cloud computing is a mixture of distributed system, utility computing and grid computing. In cloud computing, use combination of all these three in virtualized manner. Cloud computing converts desktop computing into service based computing using server cluster and huge databases at data center. Cloud computing gives innovative facility like on demand, pay per use, dynamically scalable and efficient provisioning of resources. Cloud computing the new developed technology of distributed computing systems changed the phase of entire business over internet and set a new trend.

Cloud computing is currently being used by a large number of organizations. Many consider it a major development of the decade in computing. In this article I define cloud computing, various services available on the cloud infrastructure, then discuss the technological trends which have led to its emergence, its advantages and disadvantages, and the applications which are appropriate to outsource to a cloud computing service.

This report will explore and go into brief detail regarding the technology of cloud computing. It will cover subject areas such as, what is the cloud, the history, the benefits and the drawbacks.

A cloud is a unique information technology (IT) environment which has been designed for the purpose of provisioning, scalable and measured information technology resources remotely. Cloud Computing Service provides IT as a service over the internet on demand basis and the payment is based on usage. Cloud computing services are provided from development platforms and full applications to servers and storage. Cloud computing is a pervasive advancement which gives a beneficiary way to the clients to benefit the cloud applications on interest. It refers to the network service in which services are provided with assured QoS, affordable computing infrastructures with an easy and simple access on demand and is enabled

Cloud computing is one of the biggest innovations of the 21st Century. Moving into 2014, cloud computing remains a big IT trend. It is a broad term that covers any type of computing or storage service that is delivered to users from remote servers. This mode of service has technically been in place for years, with online email services being one common example. As technology has progressed, a variety of services can now be provided from the cloud, such as file storage and the ability to run an entire program without having them installed on your computer. Cloud computing allows for pay-per-use or charge-per-use access to applications, software development and deployment environments, and computing infrastructure. Furthermore, it

Cloud computing has quickly become a popular model where computing resources are made available on-demand to the user. The unique capabilities of cloud computing has created new opportunities for IT and businesses. Cloud computing uses the Internet for delivery of cloud storage capabilities as a service to any users.
