Phobas Inc. is providing an online service for storing notes on the cloud, which can be accessed and updated from multiple devices. This is a classic example of Software as a Service (SaaS) where the software is hosted on the cloud and is provided to customers over the internet. The customers do not need to worry about the underlying infrastructure, maintenance or updates since all of it is taken care of by the service provider. Virtual Private Cloud, Platform as a Service, and Infrastructure as a Service are different types of cloud offerings with different characteristics, and they do not fit the description of the service provided by Phobas Inc.
