Cloud Computing:- Cloud computing is the process, in which network of remote servers are hosted on the internet which store, mange and process the data on remote servers instead of local servers or a personal computer. The functionality of cloud computing has the same as we are physically sitting on desktop or inside to any network of the world, which provided by any of providers over the internet. There are different basic concepts and terminologies which are used in cloud computing are discussed as under:-
Deployment model of Cloud:-
It represents the specific cloud environment which is separated by ownership, size and access. There are four types of models which are described as under:-
1) Public Cloud:- The Public cloud

Services are accessed before the time. The services are accessed in Minutes /hourly basis The services are accessed within days/weeks Once the cloud environment is setup, We can access faster than traditional computing system, where more time is needed for installation, setup and configuration of the system.
2. Capital Expenditure (CAPEX) Pay on demand, variable according the requirements. Upfront onetime cost, Fixed In cloud computing, what you need for your business or organization, only pay for what you demand, while traditional have maximum cost of purchasing hardware, software, installation and setup charges.
3. Economies per scale organizations Yes for all organizations Only for large organizations Cloud computing services are good for both large and small organization because it uses pay on demand services. However the traditional is good for large organization having large business and more expensive for small organizations.
4. Multi-tenancy Yes Generally not, but can be found in application hosting. This property is normally in cloud computing because it hosts multiple customers efficiently across shared resources.
5. Scalability Elastic & Automatic Manual In cloud computing the scalability is done automatically by up or down, However human interventions is needed to add or remove the
The idea of accessing, storing, and processing data from online server or virtual server instead of local server is called as Cloud computing. When we store data in our hard disk which is very near to computer that is called as local storage and computing but Cloud computing doesn’t access data from our hard disk.
The second cloud infrastructure that I would like to describe is the Software as a Service model, which is also known as SaaS. The SaaS model provides a broad scope of devices that are able to access software programs from one company’s applications. System as a service was developed to run applications from any device or user that has permission from the host. The book states, “Online email services, such as Gmail and Yahoo!, are good examples of SaaS” (Jill West, 2016). Cengage Learning made the Software as a
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
DFS promises that its system can be extended by adding more nodes to accommodate data’s growing. Also it can remove those not frequently used data from overloaded nodes to those light nodes to reduce network traffic. Scalability is the capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged in order to accommodate that growth.
There are several steps in this model; create roles, create hosts or storage, assign roles to hosts, and create zones, apply constrained on roles, apply constrained on zones.
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
Research has shown that cloud computing is not only good for companies but also for the environment. By moving e-mail, patient records and applications into the cloud, it will not only save the company money but also move into the future. Healthcare Professional Office, Insurance companies and Laboratories would all be able to access patient records without the patient having to fill out multiples of the same forms over and over again.
Even though cloud computing is still an emerging technology there are many benefits to our organization by adopting this technology. For instance, the reduction of operational cost, the ability to access data from any network and device, and the ability to upgrade and downgrade with ease whenever needed. Looking at the statistical data from companies that have adopted this technology, I think Partners in Heath should adopt Cloud computing. It think it is the perfect technology to solve our financial problems, as well as adding several benefits mentioned earlier.
Cloud computing is computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Clouds can be classified as public, private or hybrid
Cloud computing is able to increase the speed of business. Cloud computing offers the speed to make computing resources on an instance basis, not just need to first survey time and skilled resources in design and implement infrastructure and applications to deploy and test it. Cloud computing can engance revenue, share bigger market, or other advantages.
...Implementation of cloud systems can be implemented in stages with costs that coincide with usage. The ROI outweighs the issues or problems that could occur. Cloud computing gives a competitive advantage of being able to keep up with changes in technology without having the cost involved. Amazons cloud computing allowed companies like Ericsson to remain competitive and thrive.
The cloud storage services are important as it provides a lot of benefits to the healthcare industry. The healthcare data is often doubling each and every year and consequently this means that the industry has to invest in hardware equipment tweak databases as well as servers that are required to store large amounts of data (Blobel, 19). It is imperative to understand that with a properly implemented a cloud storage system, and hospitals can be able to establish a network that can process tasks quickly with...
of multiple types of end users. The data is stored in one location so that they
Using cloud computing, you can access your files and programs from any computer anywhere in the world, all you need is an Internet connection.
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.
