With the increasing number of users of cloud, the load/ traffic also increases and it becomes important to have some techniques to balance the load equally among all the nodes, so that the user doesn’t suffer and the services are delivered effectively and efficiently. Therefore the need for Load Balancing algorithms arises. There are a number of techniques available for load balancing. In this paper, different kinds of load balancing algorithms in cloud computing along with the challenges and the qualitative metrics for the various load balancing algorithms are presented.
Keywords: Load balancing, dynamic and static algorithms, Virtual Servers.
1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “Cloud computing is a model for enabling ubiquitous, 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 is composed of five essential characteristics, three service models, and four deployment models.” Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It provides an easy and flexible way of storing, retrieving huge data without bothering about the resources. With
The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “a model for enabling ubiquitous, 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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology
Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any
Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of
Cloud Computing provide enterprises and users with varieties of capabilities for store and process data in the data centers of third-party. It depends on resources sharing to carry out accordance and economies of scale, like a utility over a network. The basic of Cloud Computing is the extended concept of sharing services and aggregate infrastructure. It is the product of evolution and using current exponents and technologies.
Cloud Computing is a process of delivering a companies or individual’s applications and documents from any place, at any time, on any device. It is also a process in which hosted services are delivered through the internet.
"Cloud Computing is a model for enabling ubiquitous, 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
The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centres all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centres are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.
Cloud computing, in its most basic form, is “using computer services [such as computer and data storage, management and processing] that are delivered over a network” (Kim & Solomon, 2013, p. 189). For example, an organization may require a great deal of storage for their data but may not want to purchase the servers, the physical space for the servers, or the personnel to manage the infrastructure. Instead, they take advantage of the many cloud computing options and outsource their needs, hiring someone to do everything off-site usually with the goal of reducing their overall cost of ownership. As defined by the National Institute of Standards and Technology (NIST), cloud computing has five essential characteristics, three service models, and four deployment models (Mell & Grance, 2011) which will be covered, briefly, in the next few sections.
Cloud computing is computing and software resources available on demand, as a service. Computing tasks, Running Applications or storing data can be three broad categories of activities of cloud computing. There are mainly three types of services; Software-as-a-service, Platform-as-a-service and Infrastructure-as-a-service. There are four key deployment models, private, public, hybrid and community cloud. Cloud has few key characteristics like being cost effective, rapidly elastic, segueing into plethora of opportunities and innovations, resource pooling and available on-demand along with providing advanced security. Cloud computing has many advantages like being economical, quite
Cloud computing an evolving term that describes the event of the many existing technologies and approaches to computing into one thing totally different. Cloud separates application and therefore the resources with info from the underlying infrastructure, and therefore the mechanisms wont to deliver them. Cloud enhances collaboration, agility, scaling, and availableness that provides the potential for price reduction through reduced and economical computing. The word Cloud describes the employment of assortment of services, info, infrastructure comprised of pools of network, info, and storage resources. These elements are often quickly organized, provisioned, enforced and decommissioned, and
Cloud computing is a technology that has come full-circle in recent years. Computer equipment used to be too expensive for an average individual to own. The original industry model was a computer mainframe with dummy terminals. This fit the technical definition of Cloud Computing in a primitive sense because all data was stored and accessed from the mainframe. With the advent of the microprocessor, MS-DOS and Windows, hardware and software prices dropped and computers became commonplace in businesses and homes. This transition led to a model with personal computers storing data locally and not being connected to each other. Then as the Internet was created and the World Wide Web was developed to explore it, Personal Computers became
First of all what is cloud computing? Cloud computing is the storing of data and applications on remote servers, and accessing them via the internet rather than saving or installing them on your personal or office computer. In order to understand cloud computing lets divide the cloud computing into two parts. The first part is computing whenever there is a computing there is one word that comes to our mind that is nothing but a computer. Computer computes something computed that computes something with the help of processor and memory so whenever there is a word computing then this consists of processor and memory. Then we move into the second part what is cloud? Cloud is a different name that has been used for internet. It is a different
A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resource(s) based on service-level agreements established through negotiation between the service provider and consumers. The term ‘cloud’ first referred mainly to large ATM networks. Cloud computing began in earnest with the advent of Amazon’s web-based services. Yahoo, Google, IBM, Microsoft, Sun, Intel, Oracle, SAS, and Adobe followed to offer cloud computing technologies.
This report revolves around the topic of Cloud computing, Cloud computing software to be exact. For the purpose of this report information was gathered from various sources including electronic data, books, online journals and the World Wide Web. The topic of cloud computing software consists of an introduction which gives a brief history about the cloud, as well as the definitions of some key terms responsible for the growth of cloud computing as we know it today. It then goes on to define and discuss the types of cloud deployment methods also known as the different ways of approaching the cloud. They are the public, community, private and hybrid cloud. The next section then again defines and discusses the three main cloud delivery models
