Cloud Computing is the idea or concept of accessing scalable (able to be expanded) technology-enabled services using the Internet instead of a personal computer or an office server. Some of first movers in cloud computing includes Salesforce.com which introduced the idea of delivering applications through a simple website, Amazon with its Amazon Web Service, and Google Docs. Decades ago, most businesses use a centralized computing model which usually includes supercomputers where all the software, storage devices, and other things are included. But because of its very high cost which typically reaches up to millions of dollars, the demand for less expensive but more powerful microprocessors have increased in the 1980s. That, through the phases including grid and utility computing, Application Service Provider (ASP), and Software as a Service (SaaS), eventually led to the evolution of cloud computing.
In the early 1990s, as more people began to move from client-server models to internet-based computing, the concept referred to as grid computing was introduced. It originated with the idea of making computer power as accessible as an electric power grid. Grid computing eventually made it possible for different organizations to work together since it is composed of networked loosely coupled computers working together to do large scaled tasks. It is then supported by the utility computing which allowed people to rent computing services such as access to the Internet. Then, in the late 1990s, Application Service Provider (ASP) came into play and made it possible for businesses to outsource their IT needs such as software and servers which saved ...

Many companies find Cloud computing very convenient and efficient in terms of time, money, and even energy. With that, it has become really popular especially to businesses. But still, for every transaction, companies should always be cautious. Before making any decision or giving any information, a lot of things should always be taken into consideration. That is when communication between the customer and the provider plays a big part. Companies should make sure first that the services offered by the cloud providers will really be beneficial to them. They should also ask the providers regarding their back-up plans in case something goes wrong regarding the outages, security, and data mobility. In the end, it still depends on the companies on how they can make the most out of the cloud computing.
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
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.
INTRODUCTION: With cloud computing, Amazon has enabled the usage of internet and central remote servers to maintain data and applications and created an environment where connectivity and availability is unobtrusive and prevalent. Amazon offers two options for hosting applications and databases. Amazon EC2 with Elastic Block Storage allows one to run a MySQL database server on Elastic Compute Cloud, an Infrastructure-as-a-Service provider, with Elastic Block Storage (EBS). Meanwhile, another option called Amazon’s Relational Database Services (RDS) is a scalable relational database in the cloud with high availability.
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
To sum up, cloud computing may not be cost-effective, especially under some circumstances. For those enterprises which already have certain scales, upfront investment of moving up to cloud could be substantial due to the magnificent data foundation. Once an organization involved in cloud, that means it is going to rely on cloud to some degree. The efficiency of the organization might suffer from delayed technical support. Even some practical cases (MemSQL, Zynga and Uber) show cloud is not suitable for long-term business operation. Besides, a company may suffer a great loss due to cloud’s security issue. Thus cautious consideration should be taken by before the final decision.
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.
To conclude, the greatest worries about cloud computing are security and protection. The thought of giving over essential information to an alternate organization stresses some individuals. Corporate executives may waver to exploit a distributed computing framework on the grounds that they can't stay with their data secure. It profits these organizations to have solid efforts to establish safety set up. Overall, the administration might lose all its customers. It's in their enthusiasm to utilize the most progressive strategies to secure their customers' information.
Based on the payment system, cloud computing is defined as a pay-per-user or subscription based service that broadens its current capabilities and structures. In the networking field, cloud computing is comparable to grid computing, where computers in a network with idle processing cycles are harnessed to work out problems or issues that are too exhaustive for accomplishment by a single machine (Knorr and Gruman, 2011). In cloud computing, the shared IT infrastructure involves a network of servers that operate through virtualization to perform high quality and highly intensive computing processes and tasks. Using web terminology, cloud computing is the storage and data processing via the use of a web browser, rather than the direct use of the personal computer or office server. Therefore, it can be described as the provision and acquisition of information, ...
A good private cloud service makes data protection its utmost priority. It does so by building security within its system based on a company's individual needs. Cyber attacks are only going to become more commonplace. Business owners work too hard to be victims of cybercrime.
The fundamental idea behind a virtual machine is to remove the hardware of a single computer and make it a self-contained operating environment that behaves as it is a separate computer. Essentially, the virtual machine is software that executes an application and isolates it from the actual operating system and hardware. CPU scheduling and virtual-memory techniques are used so that an operating system can create the illusion that a process has its own processor with its own (virtual) memory. The virtual machine provides the ability to share the same hardware yet run several different operating systems concurrently, as shown in Figure 2-11.

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.
