Cloud Computing in Healthcare
LENGTH: 3230 words
As Cloud adoption in healthcare evolves, we expect a major chunk of healthcare services to move onto the
Cloud, allowing healthcare players to focus on providing cost effective and efficient healthcare services,
says Vishal Gupta, VP Advanced Services and Leader Healthcare Practice (East), Cisco
The healthcare industry has traditionally been considered to be a slow adopter of technology; and there are
valid and obvious reasons for their cautious approach. Many of the healthcare players have not adopted
technology completely in their environments as yet and their primary focus has been on automation of back
office systems, payment and reimbursement, digitisation of medical records, and business intelligence for
regulatory compliance and accreditation. In many emerging/developing countries like India, IT budgets are
very low. Investments in IT compete with other priorities like radiological equipment or operational
expansion.
Evolution of Cloud Technology
Technology has penetrated in human lives so much that it has started to become an intrinsic part now.
Mobile phones have brought in a revolution in the way we live. A sample study of usage of Smartphones by
US physicians in US is depicted in the figure below. We increasingly look to social media to inform our
personal and business decisions. Our expectations on communications, data, content, and applications have
increased dramatically and we look for instantaneous and ubiquitous access to information. 'anytime',
'anywhere' access to information has become a defacto requirement in today's world.
The combination of rising expectations and a rapid rate of change, pose a challenge to traditional
approaches for information technology (IT). A new approach is needed to free individuals and organisations
from the constraints of traditional IT. Cloud is a new computing paradigm. In Cloud, IT resources and
services are abstracted from the underlying infrastructure and provided on-demand and at scale in a multi-
tenant environment. Cloud has several characteristics:
* IT, from infrastructure to applications, is delivered and consumed as a service over the network
* Services operate consistently, regardless of the underlying systems
* Capacity and performance scale to meet demand and are invoiced by use
* Services are shared across multiple organisations, allowing the same under?lying systems and
applications to meet the demands of a variety of interests, simultaneously and securely
* Applications, services, and data can be accessed through a wide range of con?nected devices (e.g., smart
phones, laptops, and other mobile internet devices)
Cloud encompasses several variations of service models (i e., IaaS, PaaS, and SaaS) and deployment
models (i.e., private, public, hybrid, and community clouds), as defined below.
