Cloud Based Healthcare : Requirements And Challenges

Today is the world of IOT (Internet of things) and so that data is producing at very high rate in the form of Big data. That is why it becomes very difficult for companies and organizations to invest too much upfront cost for the setup of infrastructure and platform to handle this big amount of data. Cloud computing has come in boom around the year 2007 with rapidly growing innovative social and business organizations. Cloud computing allows its users to use the on-demand resources from shared pool of configurable resources at a very nominal price.

Cloud Computing has very many benefits especially for the businesses. First, it leads to reduced technological costs. This is because unlike purchasing of a system which is expensive, the payment is only made upon usage and thus making it cheap (Marston et al 2011). Secondly, there are much reduced

As previously mentioned, cloud computing has recently emerged as a pioneering model for hosting and distributing services over the Internet. Actually, the model entails sharing resources on a huge scale through a value effective and location independent process. While the resources on the cloud are deployed by the seller, they are utilized by the consumer (Belamkar, 2014). Cloud computing is very beneficial to organizations and companies because it is engaging to business organizations

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

The other technology applied in the healthcare sector is that of applying the connected medical devices. These devices have been applied in making sure that patient information is picked up and automatically transmitted to other connected computers for analysis and easy treatment (Desourdis, 2009). The devices usually allow the patients to see how they are fairing in real-time as well as giving them an opportunity to monitor their own lives on real-time basis. The other important technology that is important in the merged healthcare system is the of installing electronic health record systems that are hosted on physical servers with few healthcare entities by applying cloud-based systems to make sure that data security in the

Personal health record (PHR) is an emerging model of patient-centric health information exchange system, which has been often outsourced to be stored at any third party locations, such as cloud service providers. However, there have been wide privacy concerns as the personal health information could be exposed to unauthorized parties and to those third party servers. To assure the patients control over accessing their own Personal Health Records, it is required to encrypt the PHRs before outsourcing. Yet, there are issues such as risks of scalability in key management, privacy exposure, flexible access, and efficient user revocation, has been remained the most important challenges toward achieving fine-grained, cryptographically enforced data access control. For, designing the above system different methods of encryption techniques have to be studied and see what are the main advantages and disadvantages of the system as few of disadvantage in one system can be used advantage of another system. We have to study how data is stored in cloud system and how users can access them. To design a system such that it has different level of accessing flexibility such that the owner can choose which accessing is required for different user such that data tamper and data corruption can be eliminated. To design a system which has time limited access and data

One of the main benefits of cloud computing is that the company’s resources are used in other different ways and reduce the overall costs. It eliminates the need for a physical hardware computer and replace it with an online storage or a software delivered over the internet. For instance, government agencies are shifting its government IT infrastructure into the cloud and launch mobile and e-services for citizens and businesses. As an example of cloud applications in some countries: In China a company named Wang Fu Jing has deployed cloud services to share supply chain information and implement B2B e-commerce with suppliers (Kshetri, N. ,2011). Another example is in South Korea: IBM’s cloud computing centre provides architecture, skills and pilot projects for banking, telecommunications, and IT hosting services (Kshetri, N. ,2011). An Indian bank named ICICI’s uses Zoho’s applications to develop services such as personalised insurance for diabetes (Kshetri, N. ,2011). Cloud computing offers many services to companies and government agencies; applications, operating systems and data are secured in the cloud environment rather than on a physical computer that is exposed to the risk of lost, stolen or hardware failure. Compared to client-based computing, cloud-based software is easier to install, maintain and upgrade. Furthermore, mobile applications based on cloud computing are becoming increasingly popular. Ericsson estimates that there

The purpose of this paper is to discuss Cloud Computing, a new technology that has become an important tool in the business of healthcare. The paper will provide an overview of cloud computing and discuss the evolution of this new concept in business today. The paper will also examine the application of cloud computing in healthcare and discuss its advantages and disadvantages. Since there are many perspectives on HIPAA and HITECH acts in the healthcare community that have caused fears and concerns regarding security requirements for storing patient data remotely, the conclusion of the paper will review and discussed the

Cloud computing is basically a model based on “pay as you go” that reflects the best business approach for the organization to pay only for the services that are used. Organizations have adopted this approach rapidly due to the attributes of minimal investment, rapid deployment along with cost reduction. Thus, the organizations are free from monitoring and managing the technical issues as it is offered by the service providers. According to Modi, et al. [2], around 91% international organizations have adopted the model of cloud computing for its significant element of cost reduction.

The main purpose of preparing this report is to describe the concept of cloud computing, how it works, advantages, disadvantages and its entire component. Cloud is becoming famous day by day all the big organizations are adopting this technology in their campuses. Cloud computing provides a facility to deliver our all computing resources over the internet, which can be accessed at any time from any place rather storing them on our

requirements, and pay only for the services they use. However, despite all cloud benefits there

IT industry being one of the major development areas, many people choose their career in it. To support all range of industries i.e., from small scale to large scale, cloud computing emerged which reduces the efforts both physically and with regard to capital investment.

Cloud computing is a vital part of this new era IT world or we can say that it is a technology of new age which are used to connect data and application from anywhere around the planet through the internet. Anything and everything from servers to mobile phones can be connected to the cloud. It has also yielded up some new companies which are providing consumer a large range of services. Due to this the upcoming companies can now better concentrate on its major purpose and not have to worry about installing their own servers and about its maintenance. They can be very easily outsourcing it to these cloud suppliers saving a lot of capital and energy investment by them. Now,

According to the National Institute of Standards and Technology (NIST), cloud computing is referred to as a model for enabling convenient, on-demand network access to a shared pool of configuration computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. The following paper will discuss the meaning of cloud computing, the major providers, benefits of adoption, pitfalls of adoption, current trends in the business community, and current application within the business community.

If one were asked to predict the future of medicine a decade ago, I am certain only the most optimistic of people may have gotten a few predictions right. The future of health care which is based of countless variables is difficult to predict but one thing is for certain that computation will one of the most crucial aspects of its progress. Be it diagnosis or treatment computational algorithms are ubiquitous. Advances in electronics and computer science are immediately being used for betterment of health care and solve its current problems such as high costs, disintegrated care and human errors.
