DEFINITION OF CLOUD COMPUTING
This essay is primarily about cloud computing, including its definition, types, history, risks, disadvantages, advantages, and future impacts. Cloud computing refers to the delivery of hosted services over the internet. There are three categories of these services: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Cloud service differs from traditional hosting in three ways: it is sold based on the customer's needs, it can be used as much as the customer wants, and it is completely managed by the provider. Customers can easily access the service with a personal computer and internet access. There are two types of cloud computing: public and private. Public cloud services can be bought on the internet, while private cloud services are provided by a data center that offers hosted services only to specific people. Regardless of whether it is private or public, cloud computing aims to provide easy, scalable access to computing resources and IT services.
TYPES OF CLOUD COMPUTING
Infrastructure-as-a-Service (IaaS) is the basis of cloud computing and the main layer considered. This service model brings some benefits, such as control of your applications, data, operating system, middleware, and runtime. The service provider controls the virtualization of your servers, networking, and storage. This allows you to avoid expenditure on hardware and human capital, reduces your return on investment (ROI) risk, and streamlines and automates scaling. However, a basic deficiency is the lack of extra data space for processing power on occasion. With IaaS, you only pay for what you use, which can save you money.
Platform-as-a-Service (PaaS) is the second layer of cloud computing. It provides a platform for developers to build and deploy applications. PaaS offers a complete development and deployment environment in the cloud, including tools for testing, collaboration, and version control. PaaS can be used to develop web applications, mobile applications, and enterprise applications.
Software-as-a-Service (SaaS) is the third layer of cloud computing. It provides software applications over the internet. SaaS eliminates the need for customers to install and run software on their own computers. Instead, they can access the software through a web browser or mobile app. SaaS is used for a variety of applications, including email, customer relationship management (CRM), and enterprise resource planning (ERP).
ADVANTAGES OF CLOUD COMPUTING
Cloud computing offers several advantages. First, it provides easy access to computing resources and IT services. Second, it allows for scalability, which means that you can easily increase or decrease your computing resources as needed. Third, it can save you money by reducing the need for hardware and human capital. Fourth, it can improve collaboration and productivity by allowing multiple users to access the same resources and applications. Finally, it can improve security by providing centralized control and monitoring of data and applications.
DISADVANTAGES AND RISKS OF CLOUD COMPUTING
Cloud computing also has some disadvantages and risks. First, it requires a reliable internet connection. If your internet connection is slow or
Best example of cloud computing is Google drive and Apple iCloud. Google drive is an unadulterated distributed computing administration, with all the capacity discovered online so it can work with the cloud applications: Google Docs, Google Sheets, and Google Slides. Drive is additionally accessible on something other than personal computers; you can utilize it on tablets like the iPad
The first cloud infrastructure that I would like to describe is the Platform as a Service model, also known as PaaS. The platform in PaaS describes the fact that it provides the computers operating system and hardware for the use of applications. To expand on the platform description it easier to say that a company can use this cloud infrastructure in order to run their software rather than having to buy each computer and software to run a program for each computer. A plus side of using PaaS is that new developers are able to test applications in the cloud without crashing their own computer. It is also capable of storing information on the cloud which frees up hardware storage space. The traditional type of networking where you every computer had to be networked and hardwired to each of the
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.
These benefits do not just affect the patient, but they also affect the facilities and doctors providing care to the patient. Patients can expect better outcomes because they have faster access to specialists who can apply higher standards of care when evaluating them for various illnesses or other health conditions. Remote specialties can often determine if a patient absolutely needs to be moved to another facility or if they can stay where they are, allowing them to stay close to their personal support network. Physicians can extend their reach to patients who need their expertise but who would otherwise have missed out on this care without Telehealth. The entire healthcare system will benefit by Telehealth methods by being able to increase the number of patients while decreasing the number of clinicians needed for those
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.
A cloud application service provider gives users access to the software applications remotely via other networks if not the internet. Businesses are freed from installing and maintaining software on personal software computers. . Again, the personnel in branch or remote offices can
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.
Virtualization technologies provide isolation of operating systems from hardware. This separation enables hardware resource sharing. With virtualization, a system pretends to be two or more of the same system [23]. Most modern operating systems contain a simplified system of virtualization. Each running process is able to act as if it is the only thing running. The CPUs and memory are virtualized. If a process tries to consume all of the CPU, a modern operating system will pre-empt it and allow others their fair share. Similarly, a running process typically has its own virtual address space that the operating system maps to physical memory to give the process the illusion that it is the only user of RAM.
I would picture this kind of scenario is like having a walking hard disk all the time with you.
Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
Cloud computing is a type of computing that depends on sharing computing resources rather than having local servers or personal device to handle applications.
