Question - What is the Public Cloud?
Answer -
Be it a public or private cloud, the primary objective is to deliver internet services. Unlike a private cloud, public cloud services are third-party applications that can be used by anybody who wants to access them. The service may be free or be sold on demand.
Public clouds are open to people for use and deployment. For example, Google and Amazon, etc. The public clouds focus on a few layers like cloud application, providing infrastructure, and providing platform markets.
