Cloud Computing
In this report I will be looking at cloud computing, I will begin with an overview of cloud computing. I will then look at the advantages that cloud computing brings to the table. Lastly I will be looking at the concerns that people have with cloud computing.
What is Cloud Computing?
Cloud computing is computing that involves a larger number of computers that are connected over a communication network such as the internet or access and storing data over the internet instead of your hard drive. There are four main types of cloud private, public, community and Hybrid.
Private cloud is an infrastructure that operated within a single business or organization firewall. There are highly virtualized and privately owned and managed. An example of a private cloud is StudyNet that is run by the University of Hertfordshire.
A public cloud offers services such as applications and storage over the internet for general use. Public cloud services can be offered on a pay-per-usage mode so that you only pay for what you use. An example of a public cloud is the TV and film services Netflix what lets users stream content anywhere in the world to their mobile devices.
A community cloud is a cloud infrastructure that is shared be several organizations that have common computing concerns, such as audit requirements. The goal of a community cloud is the pay-per usage of a public but with the security and privacy of a private cloud. An example of a community cloud is the UK government G-Cloud that is used by the public sector.
Hybrid cloud is cloud infrastructure that consists of a minimum of one private cloud (internal cloud) and one public cloud (external cloud). The use of hybrid cloud is so business can keep mission-crit...

...ct to the cloud and are able to access from where you are. Cloud computing can be access from range of electronic devices that able to connect to the internet such as smartphones and tablets.
A cloud computing system can be sent up and running in a very short period. A new user being added to system happens instantaneously and eliminates waiting periods. In cloud computing the software integration is done automatically, which prevents downtime using the system.
A Cloud computing system grants small to medium enterprise access to enterprise-class technology which they would not usually have access to because of cost.
Cloud computing is general more efficient than your typical IT Infrastructure and takes less resources to compute saving energy. Using the cloud computing you can save up to 30% less energy consumption and carbon emission then using on-site servers.
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
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
OpenStack is an open-sourced company independent private cloud platform built with segregated resource pools that can interconnect. For example, a virtual machine can be created using OpenStack Nova, which will connect into the block storage component to store data. The same server can be connected into a vLAN(virtual network) to have other servers throughout various locations connect to one network without costly networking hardware. Configuration is relatively easy as there is need to count, track or monitor which servers have the software installed. Managing the VMs created in OpenStack Nova is also easy as it is possible to use the CLI from the browser through a VNC proxy. In fact, all of the resources and modules can be managed from the browser.
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.
Creating a hybrid cloud which entails taking a strategic approach to cloud adoption by determining what data you want to move to the cloud to avoid unnecessary business disruptions and support customers’ needs.
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 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.
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
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.
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.
