Infrastructure as a Service (IaaS)

IaaS is the most complex but also the most flexible of the three. It’s typically used by companies and enterprises that need full control over their data and applications.

IaaS provides the infrastructure—servers, storage, and networking—but users must configure the operating system, runtime, and applications.

Examples include AWS, Google Cloud Platform, and DigitalOcean.

In short, cloud computing ensures that you don't need to deal with bulky hardware and infrastructure for any activity you engage in online.
