Differences:
Some of the differences between Cloud and Autonomic computing are as follows:
a. Cloud Computing is more of a virtual computing interface, in which the environment where users work is not actually connected to a single machine. Cloud Computing involves the leasing of computing infrastructure and software via the internet, so that the virtual environment is completely maintained at a remote location. The users do not know where the infrastructure is or the paths their data takes. Because, of this, Cloud computing allows for greater accessibility, since users do not have to understand the tools and programs that create the interface whereas in Autonomic computing, at its most basic level, requires an understanding of the infrastructure

b) Both computing types involve multitenancy and multitask. This means many customers can perform different tasks by accessing a single or multiple instances of resources. Sharing resources help in reducing peak load capacity [32].
c) Cloud and Grid Computing provide services level agreements for guaranteed uptime availability. If the service slides down from the level of guaranteed uptime service, the consumer gets service credit [32].

b) Major difference between Grid and Cloud computing is Grid systems are architected in the manner such that individual user requests can consume large fraction of the total resource pool and Cloud systems often limit the size of an individual request to be tiny fraction of the total available capacity. The focus of Cloud computing is to support large number of users and the focus of grid computing is to allocate maximum amount of resources to handle single request from user in order to finish the task in minimum amount of time.
c) Cloud Computing gives good efficiency even for small service. Ex: Amazon S3 provides services for storage and retrieval of data in the Cloud. Data as small as 1 byte and as large as 5 GB or even more can be stored in Cloud servers. But, the storage service in Grid computing is well suited for data-intensive storage. Storing as small as 1 byte in data grid is not economically suited. The amount of data must be large for maximum benefit
Today, cloud services are widely used by people around the world in purpose of business, government, and personal use. With cloud services, users use resources - could be storage, computional capability, or software- from cloud service provider mediated by Internet. Doing computational work with cloud services involves a number of computers to do the large-scale works, therefore it usually called by distributed system over Internet (reference, paper?). Cloud service also offers a large-scale service where users only pay for what they use (on-demand). Therefore, companies migrate to business-to-business cloud as they don’t have to spend money building intial cost for their computational business. For instance, instead of building their own storage, network, cooling, they could just “rent” resource from cloud provider for the lower cost. Besides money benefits, cloud resources also able to be shared by multiple...
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.
... dynamic scaling, cost variability and utility pricing model. Instead of purchasing infrastructure equipment, companies can buy resources as a fully outsourced service on demand by using IaaS cloud computing. IaaS also offer two cost savings of the cloud computing for Innovartus Technology, economies of scales and utility-based pricing model. Finally, like PaaS, but IaaS offers better services for software development and focuses on workflow management regardless of the data source used for the application.
Cloud computing is a relatively new technology that allows data to be stored, distributed and manipulated with greater ease than ever. As described by Gurjar and Rathore (2013), the “Cloud is a large pool of easily usable and accessible virtualized resources. These resources can be dynamically reconfigured to adjust to a variable load, allowing also for an optimum resource utilization” (p. 1). By moving data, documents and media to the Cloud, the potential for business efficiency and productivity increases and anyone with internet can take advantage of the benefits. As with anything, it is important to understand the risks and benefits in order to weigh whether or not moving to the Cloud is the best move for the business. Some companies, like Lavu, an iPad based point of sale system, operate solely on the Cloud. Without Cloud computing capability, some organizations would not exist.
From our research we can describe Cloud computing as both a platform and a type of application. The Cloud computing platform offers, configures, reconfigures and provisions hardware and software services as needed. Server equipment in the cloud can be physical or virtual machines. Clouds in actuality also offer storage area networks (SANs), network equipment, firewall and other security devices. Cloud computing refers to applications that are not stored or ran from the local systems, but that exist on the cloud and are accessed remotely. Any user with suitable internet connection and standard browser can access a pool of virtualized computer resources in the cloud.
Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. In addition, the platform provides on demand services to the users for accessing that are always on anywhere, anytime and any place. Cloud computing platform provides the scalability, availability and utility computing for services on Internet.
Enterprises and individual users are outsourcing their services on the web, instead of maintaining the resources of their own. Outsourcing of technical resources enables the organization to concentrate on business need instead of technical aspect, which is looked after by the expert of the IT area. To facilitate such users, a web based paradigm known as cloud computing has emerged and offering the services on utility model [p3]. The major goal of Cloud computing is to reduce the operating cost, increase throughput, increase the reliability and availability [p10].
Cloud computing : Cloud computing is a new class of network based computing that takes place over the internet. Large number of remote servers are allow to centralized data storage and there is online access to computer resources and services.
Cloud computing is sort of like the first computers come full circle – in the early days of computing, users at terminals with no computing power to speak of made use of the number-crunching capabilities of mainframes in a shared fashion – in fact, the model of computer use was called “time-sharing.” As the personal computer grew in power and capabilities while also becoming a cheap...
Cloud computing remains firm and has great potential for the future despite its disadvantages and the fact that it is still is a working progress. The number of users are constantly growing and bigger companies are starting to be interested, offering better and finer tuned services and solutions. The best thing to do is to hope that the advantages will further grow and flourish and the disadvantages will slowly disappear, since cloud computing seems to have made IT a little bit easier (Morris, 2011).
The term used as cloud computing is a wide term. It includes a wide range of different services. Cloud computing is also known as on demand computing. This name is given to cloud computing because it provide online services to different persons on computer by sharing processing resources in addition with data to computers depending upon different demands.
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.
This section point up the idea of Cloud and Grid Computing, it find out some is-sues and compare both technology. Cloud computing and grid computing are widely used now-a-days. Cloud computing becomes crowd pleasing and it is in the main-stream. Cloud computing is an transpire model for business computing. Cloud computing is moderate and economical than the grid computing, that is the reason it reduces the user’s cost. Grid computing is tightly coupled whereas cloud computing is loosely coupled. Basically, cloud computing is based on grid computing but if grid computing is to be discussed then there would be possibility that it may be cloud or maybe not. Cloud stakes the services. Grid can be considered as a middleware that enable sharing and managing grid components based on user requirements. Cloud computing consists of three things: clients, grid computing, and utility computing. Grid computing provides computing resources as a utility that can be used or not while cloud computing moves one step forwards it provides on-demand resource provisioning and eliminates over provisioning when used with utility pricing. Increasingly, IT companies are switching to cloud computing. There are some types of cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), storage as a Service, Information as a Service and Software as a Service (SaaS) [4][5].
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
