What is Cloud Computing?

Before delving into the specifics of healthcare, it’s essential to understand the fundamentals of cloud computing. Essentially, cloud computing involves delivering computing services – servers, storage, databases, networking, software, analytics, and intelligence – over the Internet (“the cloud”). Instead of owning and maintaining physical data centers and servers, organizations access these resources on demand from a cloud provider.

There are three main service models:

Infrastructure as a Service (IaaS): Provides access to basic computing infrastructure – servers, networking, storage. Users manage the operating system, middleware, and applications. Think of it as renting the hardware.
Platform as a Service (PaaS): Offers a platform for developing, running, and managing applications without the complexity of managing the underlying infrastructure. Developers can focus on coding.
Software as a Service (SaaS): Delivers software applications over the Internet, on demand, typically on a subscription basis. Users access the software through a web browser or mobile app. A prime example is a web-based EHR system.

Deployment models also vary:

Public Cloud: Services are offered over the public Internet and are available to anyone. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
Private Cloud: Infrastructure is dedicated to a single organization. It can be hosted on-premises or by a third-party provider.
Hybrid Cloud: A combination of public and private clouds, allowing organizations to leverage the benefits of both.
Community Cloud: Shared by several organizations with similar requirements.
