Cloud Computing Definition:
Cloud computing is an internet-based technology that provides shared processing data and resources to the computer and other devices.It allows users and enterprises to store and process their data in third-party data centres. Due to this technology, various businessmen & consumers can easily use applications without installation and access their files from any computer with internet access.
Through cloud technology, users can access their Gmail, Hotmail, yahoo mail etc at any anytime with internet access. In consumer-oriented applications such as financial portfolios, this computing performs tens of trillions of computation per second. In our previous articles, we explain how healthcare transformed by technology, healthcare meets gaming, Healthcare types etc. Here we are going to explain how cloud computing changing healthcare in detail.
Cloud Computing In Healthcare:
Today’s lots of healthcare sectors depend on paperwork, to modernize and reform this sector cloud computing technology is adopted. In Healthcare industry, it plays a vital role in moving the healthcare to a digital platform becoming more patient centred and data driven. This computing technology helps healthcare industry in storing large data, sharing information among hospitals and physicians.
In healthcare, large multinational organizations such as Microsoft, Philips, Verizon, AT& T etc have launched cloud-based vertical solutions. It provides the infrastructure that allows medical practices, hospitals, research facilities and insurance companies to use improved computing resources at the lower initial capital. Day by day cloud computing becomes the key technology requirement of the healthcare IT industry. Following reasons are:
- Store and share large data files involved in medical imaging.
- Supports big data sets for radiology images & genomic data offloading, Electronic health record (EHR) , burdensome tasks etc from hospital IT departments.
- Improves the ability to track and analyze information.
- In various geographic areas, it facilitates the sharing of EHR’s among authorised hospitals and physicians.
This computing technology allows the organization to pay only for those resources whatsoever needed. To create a highly flexible environment with computing technology, all shared resources are allocated dynamically. As per the recent survey, in healthcare provider organization, 83% of IT executives report that they are using cloud-based services with SaaS-based applications. As per the business requirement, the healthcare industry will choose any one of the cloud service models. Three types of service model are explained below:
(i) SaaS ( Software as a Service):
Saas is one of the most attractive models delivers software applications over the internet. For productivity and email services, Microsoft Office 365 is the SaaS offering reduces the capital expenses, needed for hardware, software and other applications.Following benefits of SaaS are:
- Access data and apps from any connected computer.
- Pay per use business model especially for small physician practice.
- Data is in the cloud ensures data safety.
(ii) IaaS (Infrastructure as a service):
Healthcare industry that seeks more scalable infrastructure would prefer this service. This service provides companies scalability with security, defined service level agreements, built in backup and data protection. Following benefits of IaaS are:
- Provide flexible and innovative services on demand.
- No need to invest on your own hardware.
- To support workloads, infrastructure scales on demand.
(iii) PaaS (Platform as a Service):
Larger healthcare institution prefers this service to develop their own cloud-based solutions. This service provider typically develops toolkit and standards for development and channels for distribution & payment. Following benefits of PaaS are:
- Reduce complexity with middleware as a service.
- Deploy new applications to the cloud.
- Develop applications faster.

Advantages of Cloud Computing:
As we know, previously people would run applications or programs from software downloaded on a physical computer or servers in their building. To overcome this, cloud computing technology came into existence which allows users to access the same kind of applications through the internet. Following of its advantages are:
- Environment Friendly
- Capital expenditure free
- Automatic Software Updates
- Disaster recovery
- Increased Collaboration
