Yunshan and see what clouds are floating in the sky

Abstract: Cloud for everyone is not unfamiliar, the Internet from the birth of that day, in their own blood flow of a piece of cloud. The concept of cloud computing can make the calculation cost and storage cost drop greatly, it is the biggest aspect that it can gain popularity.

Define Cloud

With the development of information technology in the cloud computing model, the industry will continue to debate and improve the competitive supplier's cloud-related software, technology, and attempt to guide the definition of cloud computing for enterprise evaluation services, and ultimately appropriate cloud-based IT services. A quick survey of public resources shows a group of related breeds, although not exactly consistent with the definition of cloud computing:

In different definitions, while describing the different aspects of some cloud models, the track revolves around an application or provides services through the Internet or through a dedicated network to achieve gage predictions, computer resources tight "network is computer".

Explore Cloud

The Gartner Framework provides a useful starting point for a deeper understanding of cloud computing. Let us in all aspects of this framework and how they relate to the health care world.

An electronic health archive or an infrastructure-type picture archiving and communication System (PACS) provides archival storage services through a cloud computing model to provide a service that is based on an application as well known and manageable operating parameters as an already predetermined range of operations. This service provider may allow customization or localization of individual customer services, or may limit these customized minimum requirements to maintain the technical and financial viability of the application.

As a service (IaaS) infrastructure, including virtual servers, storage, networking, firewalls, backup, recovery, archiving, and related management tools. The IaaS provider creates a dynamic, managed technology environment that includes one or more services. Some services have a very clear focus on a component, such as network-based backup, while other services provide complete virtual data that can be at the center of the customer's flight running their application configuration in the cloud. Medical institutions need or want to customize a wide range of applications that can still benefit from the scale and cloud model flexibility considered as a managed part or all of the application means of IaaS.

It is important to clarify the differences between traditional mainframe and IaaS. Traditional mainframe dedicated to specific infrastructure, hosting agencies. It is essentially the same configuration that the organization will run within the company from the host provider. Managed service providers must take business and technology disciplines to the added cost of overcoming WAN resources (and self hosting).

In contrast, IaaS is intended as an effective computing tool. Some parts of a common, highly scalable infrastructure are dynamically assigned to each customer, producing through a pooling of services providers and possible tradeoffs of resources, That is, IaaS may in some cases have an essentially more efficient use of cost-saving service levels for customers is not the best choice for an organization's it needs. In this case, hybrid IaaS and traditional hosts can still be beneficial for both customers and service providers. In any case, medical institutions considering the data center investment, whether within the enterprise or in the service provider's "cloud", will be well advised to apply to the cloud design discipline infrastructure to obtain optimal resource usage.

Because of IaaS's creation of "virtual data centers", we do not have to limit our horizons to the IaaS of traditional data center assets. The lowest value, but the hospital's IT department provides one of the highest profile services is the personal computer or client configuration, operation, management and support. This is a thankless task, which is almost never satisfying to the user, and produces burnout, turnover, and low morale in the IT department. Through desktop operating environments such as Windowsxp,windowsvista or Windows7 virtualization, and even a single application virtualization, it is now technically possible to fully manage desktop images in cloud computing using the same basic resources and managing the technologies available for use in data center assets.

Desktop virtualization is a development and powerful tool that healthcare providers can use to improve end-user client experience, create a consistent look and feel for a variety of computing devices, and enhance security while reducing configuration and management costs. As virtual desktop products begin to be fully embraced, such as single sign-on using biometric passwords and context-sensitive computing, medical service providers will be given the ability to reduce costs for customers while improving the user experience with powerful tools for health care standards. Some it dreamers even predict that when laptops, desktops or mobile devices are no longer provided by the employer for the day, but will be a personal choice, employees make the devices they use to access the cloud-hosted virtual desktops with corporate support, allowances or platform options in the deep enterprise offering preferential support

As a service platform (PaaS) expansion infrastructure, as a service with a number of core applications, operating systems, and often software development and implementation service provider management tools. Increasingly, these applications and operating environments are open source software or open source software that has been changed to make it possible for "enterprise-class" customers to quickly implement applications in these pre built environments. One of the frequently mentioned success stories of this model is the classified ad site "Craigslist", which is established and still working in a PAAs model, and is kept by surprisingly small groups of effective developers and managers. In health care, some doctor portals and hies are under construction in the PAAs model by specialized medical IT service providers who then use PAAs tools to suit their actual medical platform provider customer needs.

Software as a service (SaaS) is the heart and provides cloud-based software solutions that consumers receive a "seat" or access to the software provided by the ability of the soul to log in. If you are using Gmail,facebook or online banking, you are a SaaS user. SaaS is that many industry insiders analyze the value of the cloud model in the final market performance. SaaS is built on cloud platforms and architectures, completely a "weapon length" service, the user is not in the design, configuration, or provide the role of software management, but only the use of "as is" under the cost pricing model, start possible advertising support, and extend to the price per month for each seat, as well as the specific metering used. SaaS is the emerging health care practitioner EMRs most visible or electronic health files, as mentioned earlier, and in web-based portals to more traditional hcis applications, in health information exchange and applications, different material ordering and fund-raising.

SaaS will take a slow first demand for harsh medical information system applications, which requires extensive customization of online analytical Processing (OLAP) database performance and styling of user and organization-defined parameters. In its purest and most efficient form depended on the SaaS of the multi-tenant, the multiple footprint of the technology architecture, which is another way of saying that multiple organizations can be compliant with any required "walls" between existing and common applications and a common technology infrastructure, in ways that data sets are imposed by any application or software itself as a virtualization layer. The highly visible SaaS success in the commercial space platform, an example of Salesforce.com, is driving innovation in this area. Medical institutions will not have to wait for independent software vendors (ISVs), technology development, and long service providers in the SaaS Marketplace to create software and management tools that allow the necessary customization while maintaining the inherent efficiency of the model.

Other potential SaaS benefits for medical institutions such as miniature editions and community procurement functions. Driven by their healthcare customers, independent software developers and service providers in the SaaS domain will be more frequent, customer-driven updates, and medical application workflows without interruption or downtime. The centralized control of these updates ensures that all users receive and benefit from change. Community sourcing allows skilled SaaS customers to actually develop and propose updated SaaS software based on their own experience. This ability is likely to rapidly spread to different populations of major software and medical information system operations improvements. This type of organic reactive environmental change preserves better drug development links to Real world clinical experience and seeks a more coordinated response to future large-scale emergency medical potential commitments.

Scalability and elasticity

Cloud computing offers unique benefits that are fully scalable and can grow and shrink in the famous parameters. In cloud Computing's global industry, even the biggest hassle of managing resilience is the edge. Amazon and Google, it can be said in this area of Leviathan two, suffer as a result of certain web-based applications that are almost impossible to anticipate and scale in advance to fully absorb the demand for peak demand for the unpredictable paralysis disruption. These "consumer-grade" service levels will not be accepted by the health care, which increasingly, the integrity of the patient's life and work can be threatened through it disruption. As a result, medical institutions will observe the emergence of mixed cloud and cloud providers who combine the financial benefits of cloud computing with the expertise of a specific health care discipline in the field of cloud-based business, while reducing risk through time-tested IT management processes.

Shared infrastructure to build economies of scale

Scalability and infrastructure sharing reduces the traditional cloud computing infrastructure's management and utilization, services and the entire vast population, and ultimately through public and private networks, delivering similar unit costs. It is worth studying how to address the integration into your internal IT operations balance or with other cloud-based services. To meet the computing requirements, the cloud model will ultimately force us to expand our common infrastructure definition, including dynamic external private cloud and public cloud allocation infrastructure. A new segment of security software is being established to ensure seamless fluid distribution across the network infrastructure to achieve security.

In order to obtain the IaaS, the possibilities of PAAs and service provider external private cloud SaaS products are fully exploited, and the organization of discipline needs to be developed within private cloud will, with the development of technology, leveraging secure network technology and evolving virtualized application programming interfaces (APIs) for seamless federated Local hosting in the public cloud , or the Internet, as well as the applications and services provided by the external private cloud provided by the service provider.

Cloud computing risk/rewards in healthcare applications

Some industries have shown that cloud computing is beneficial and provides a safe and reliable computing model. How fast Health will move in this direction is likely driven by the same forces that drive credit card trading and E-commerce many years ago.

Generally accepted statistics show that perhaps the greatest risk of medical quality is the lack of access to comprehensive medical records in order to make appropriate care. The adoption of these systems has become a key medical service provider in the near term, in part because of the ARRA including the Incentive Fund.

The service provider who is providing "as a service" solution business must be checked to prove its ability to maintain the lifecycle service levels through adoption and use of services. To complete such an evaluation, the medical staff may consider the following attributes:

1. In these two areas of expertise and technical processes of medical solutions, effectively meet business or clinical requirements.

2. A cohesive partnership that eliminates disappointment in services. There is nothing more than a blame fight for who is responsible for causing or fixing problems.

3. A distinguished well-known culture. With the development of the market with price per Use mode, the quality of service becomes the key factor of the total ownership cost of the formula.

4, a technology-neutral view, including a more objective way to select the best provider of services and solutions to enable customers and consumers. All solutions are not equal. Choosing a subscription model allows easy improvement between migration as a solution without loss of institutional investment in one of the solutions.
