Five Benefits Of Cloud Computing To Healthcare
October 22, 2012
As its name may suggest, “the cloud” is a mysterious yet increasingly ubiquitous presence in all parts of life. Realistically, its definition is simple: cloud computing takes advantage of economies of scale and resource pooling to provide massive amounts of storage and computing power to any users who sign up for the service.
Cloud computing is still a relatively new force in computing, but it’s already beginning to make big inroads in health IT as well. Here are five benefits of cloud computing to healthcare:
1. Data security: resiliency. The cloud infrastructure offers durability and up-time that far exceed what any hospital’s IT department could offer. Because of economies of scale, large cloud service providers are able to build large redundant data centers that place a higher emphasis on backup, data resiliency and uptime for lower costs. Cloud storage, for instance, can cost as little as 10 cents a month for “fast” storage and a penny a month for “cold” storage. There’s a higher bar of excellence for a cloud provider, surrounding the integrity and ease of secure access to data.
2. Data security: privacy. Is cloud data less secure? The truth is the levels of security are much higher than what you see in a local IT department. Security in a hospital’s server room can be as little as just keeping the door locked; when data is in the cloud, however, it forces you to put all of your security in the application layer. Data on the server is “an encrypted blob of bits,” that even the cloud provider has no access to. Cloud providers also rely on their economies of scale to maintain systems that attest to privacy standards such as PCI (credit card industry), HIPAA (healthcare industry) and FISMA, the Federal Information Security Management Act, which has more than 400 controls that need to be audited.
3. Speed of innovation. For reasons partly discussed above, cloud-based services can upgrade and improve their services rapidly, cheaply, and with minimal or no interruption to service. The cloud is all about rapid innovation. Allowing the cloud provider to continually improve the data and computing power frees up the local IT staff for “value-added tasks,” such as infrastructure maintenance and administration.
4. Mobile applications. Every great mobile app is backed up by some cloud infrastructure. The two trends of cloud computing and mobile health are inextricably linked: All behind the scenes is the workhorse that powers the app. Mobile uses a lot of backend cloud services. By storing all of its data and computing power in the cloud, a healthcare provider enables staff to have access to information anywhere it wants to make it available. For large institutions, or partnered organizations, that data may be needed in two places at once and can be synchronized and shared in real time. Transitioning to a cloud service enables greater speed and access for healthcare providers, as well as patients. The next wave is an app someone can get, that someone can fill out and collect data for their healthcare provider.
5. Developing trends. Along with all the ways cloud computing can integrate in to existing uses, it seeks to replace more uses and empower more people and systems. It makes sense to transition to cloud based services because they enable doing similar kinds of things for less money on a bigger scale. They remove inefficiencies in IT. Another strength that cloud services provide is their ease of access. Cloud service providers have been “good about pushing open formats instead of closed formats meaning that the structures and file systems employed are open and easily adaptable to. This makes adopting a cloud system as a replacement for a localized one much easier, more efficient and cheaper.
